Ryan Chartier: Welcome, everybody. Let's give it another minute or 2. Let people join
Ryan Chartier: alright, just for the sake of keeping on schedule. Let's go ahead and get started. Welcome everybody to the air Quality and Southeast Asia Workshop, funded by the Department of State.
Ryan Chartier: we'll have about 6 presentations today to get through
Ryan Chartier: and I do have a hard stop at about one Am. My time, but if I have to drop off one of the other Aqc. Members will be able to take it going forward.
Ryan Chartier: so first off we have an introduction to the Department of State program by Adam Ross
Ryan Chartier: Adam.
Adam Ross: There we go.
Adam Ross: Think I'm I think I'm unmuted. Now
Adam Ross: let's see here.
Adam Ross: Great. Well, good morning. Thank you. Thank you, Ryan. Can you hear me?
Ryan Chartier: Yes, I can hear you.
Adam Ross: Great great.
Adam Ross: Well, it's it's a pleasure to join you all this morning.
Adam Ross: As Ryan said, my name is Adam Ross. I am the director of the State Department.
Adam Ross: Regional Environmental hub. Here in in Bangkok, Thailand, we serve as the hub for
Adam Ross: US. State Department, environmental engagement across so.
AcAir CMU: With that.
Adam Ross: Southeast Asia. But again, it's a pleasure to really say we've been seeing a lot of interest from our network and our colleagues on air quality challenges across Southeast Asia.
AcAir CMU: Relax.
Adam Ross: So just wanted to start with some introductory.
Adam Ross: And oh, my!
Adam Ross: Sounds like there's some background noise that maybe some of your colleagues have their their
Adam Ross: audio on. Maybe we can just mute that just for everyone's.
Ryan Chartier: I'm hearing it as well. I think it might be one of the A/C air folks is unmuted.
Adam Ross: Okay.
Adam Ross: well, I'll I'll jump right in air pollution is a cross cutting global threat to human health, economic development and environmental quality
Adam Ross: and reducing and eliminating pollution while expanding the number of people who can breathe clean air are critical priorities for the United States.
Adam Ross: We remain committed to advancing global action on air pollution. And that's why we're joining you here today. We know that gaps in data standards and practical air quality management guidance are some of the biggest barriers to advancing effective global air pollution management.
Adam Ross: Despite the availability of low-cost sensors, satellite data and modeling to inform policymaking. There are many places in the world where data on air quality simply doesn't exist, and
Adam Ross: it's nearly impossible for policymakers to legislate to reduce air pollution while blindfold, blindfolded.
Adam Ross: In late 2022, a study by global health visions in partnership with Unpip
Adam Ross: and the Clean Air Fund surveyed environmental officials and academics working across 119 countries, and they found less than a third of the countries had successfully implemented air quality monitoring networks, or had air quality management strategies.
Adam Ross: practitioners cited the lack of technical capacity as one of the greatest challenges faced by air quality management practitioners, second to only to insufficient funding.
Adam Ross: And surprisingly, these technical challenges were reported as bigger barriers to any lack of political support or authority. To implement programs
Adam Ross: this technical gap is compounded by poor alignment among agencies, institutions and partners providing air, quality, management, guidance.
Adam Ross: and individual agencies. Fragmented approaches can lead to the unnecessary duplication of resources, and at times conflicting information. And then the cross, cutting nature of air pollution. As a health environmental and climate issue means it often falls between the cracks.
Adam Ross: So to improve the availability and understanding of air quality data. The Us. State Department has supported the Research Triangle Institute to carry out this building. Air quality, capacity in Southeast Asia.
Adam Ross: activity in collaboration with academic institutions in Lao Thailand, Vietnam
Adam Ross: to deploy a network of low-cost air quality sensors.
Adam Ross: We look forward to hearing more about the successes and challenges of this activity in furthering both understanding and local capacity in addressing transboundary air pollution.
Adam Ross: We're especially interested to learn about the connections and gaps between data from various sources.
Adam Ross: from low-cost sensors to reference grade monitors, and how this data reaches and informs policymakers.
Adam Ross: as we all know, without accurate and trusted data and agree upon standards. Policymakers can't effectively work to mitigate air pollution through legislation or regulation.
Adam Ross: Challenges like these led the United States to work with partner countries to introduce an air quality resolution at the Sixth UN Environment Assembly in Kenya just last month
Adam Ross: we were extremely pleased and encouraged that Uniax concluded with a resolution to develop a global knowledge sharing platform and regional cooperation to tackle air pollution.
Adam Ross: We welcome this landmark resolution and urge governments to mobilize more funding for this much-needed platform, especially for data collection, and to promote more robust
Adam Ross: regional coordination.
Adam Ross: We expect this new global platform will promote promote regional cooperation to improve air quality building on the momentum already created by the Regional Action program on air pollution currently underway at the United Nations Economic and Social Commission for Asia, Asia, and the Pacific or Unscap.
Adam Ross: to feed into the establishment of a new global unep air quality Knowledge platform. The Us. Has worked to increase its support for regional resources, to improve air sheds.
Adam Ross: In September 2023, the State Department announced a partnership with Scap to launch a project to develop a methodology for improving air quality in airshed spanning multiple countries.
Adam Ross: Another US. Effort to build regional air quality data is our surveyor Southeast Asia program.
Adam Ross: which uses satellite data to bridge gaps in terrestrial collection and helps countries understand trans boundary air pollution flows in the region.
Adam Ross: Surveyor, Southeast Asia works with governments to improve the accuracy of satellite based air pollution data by incorporating data from regulatory grade instruments and makes comprehensive air pollution information available to the public
Adam Ross: surveyor is now facilitating a partnership between the tie and allow governments to improve air quality management, including ditties, community engagement and policy improvement.
Adam Ross: And you may have also seen news of a NASA aircraft that flew over Thailand in march in cooperation with Merritt, the National Astronomical Research Institute of Thailand.
Adam Ross: which worked to analyze and better understand air pollution at various atmospheric level levels
Adam Ross: with so much work being done to improve regional knowledge, resources and expertise in air quality management. We're increasingly looking for opportunities to leverage our password
Adam Ross: to avoid the duplication of efforts and to build and harmonize communities of practice.
Adam Ross: More specifically, we're looking for opportunities to grow regional networks
Adam Ross: like the ones you're a part of here today, we believe regional frameworks, like the one established under a Qse provide a natural mechanism for coordinating donor assistance for air pollution initiatives ensuring donor resources, have the maximum impact in creating sustainable paths to achieving clean air.
Adam Ross: The State Department has an ongoing program with the World Resources Institute on strengthening air quality communities of practice in Southeast Asia.
Adam Ross: This project brings together air quality practitioners from Indonesia, Malaysia, and the Philippines working to strengthen air quality forms in that region.
Adam Ross: Wri's air quality management framework works to strengthen the technical capacity and networks of air quality experts in the target countries, and it also supports the regional sharing of expertise, expertise and experience on air quality management.
Adam Ross: and provides guidance to stakeholders on using existing and previously implemented tools to enhance action on cleaner solutions.
Adam Ross: we now hope to leverage the communities of practice convened by the Wri Project as a resource to inform and enhance Scap's work, to develop a methodology for improving air quality in regional air sheds.
Adam Ross: And we believe these regional communities practice can contribute to strengthening the dialogue among transb boundary air sheds, crossing multiple countries.
Adam Ross: growing regional communities of practice can also help us adapt developing air quality guidance to local contexts, languages and capacities. They can help adapt air quality management tools develop for high resource settings for their more effective use and low and middle income countries where access to equipment or capacity levels may be very different
Adam Ross: with this in mind. The Us. Is now looking at opportunities to extend the communities of practice work now being Indonesia done in Indonesia, Malaysia, and the Philippines
Adam Ross: into the Mekong sub region where we can continue our work to build trust in the low cost sensor network deployed through the Aqsa program and to help local air quality committees of practice work in greater harmony across projects and countries.
Adam Ross: All this work.
Adam Ross: from the Unia resolution to high tech satellite data to NASA, over flights, to
Adam Ross: building networks for air quality practitioners is intended to strengthen our collective regional understanding of the importance of air quality and of our effective measures to improve it.
Adam Ross: We hope our shared efforts to build robust regional networks of air quality practitioners and stakeholders can eventually enable and inform stronger regulation and legislation at the national level across the region.
Adam Ross: I look forward to hearing more today about all of your work, towards the goal of cleaner air for all. Thank you so much.
Ryan Chartier: Yeah with you.
Ryan Chartier: Alright. I'm going to kick this off with my presentation. See if I can get this right on the first try
Ryan Chartier: everybody seeing the presentation, not the speaker. Version.
Ryan Chartier: Okay, great.
Adam Ross: Yep.
Ryan Chartier: Thank you everybody for for joining us. I'm going to give a brief overview of what? We're calling the Aq. Project for short. The full title of the Projects building air quality, monitoring capacity in Southeast Asia.
Ryan Chartier: I will try to keep this relatively short. I wanna make sure all of our speakers from Southeast Asia do have enough time for their presentations, and I think, you know, based on looking at who's present in the
Ryan Chartier: who's attending that? Most of us have already had some background information provided on on the project.
Ryan Chartier: so just to introduce myself, I'm Ryan Shorty here. I've been at Rt. International for about 13 years. Now, analytical chemist by training, and most of my research has recently focused on direct personal exposure measurements to particulate matter
Ryan Chartier: all over the world. I was tangentially involved with this project for the majority of the the lifetime of the project.
Ryan Chartier: My colleague, Prakash.
Ryan Chartier: was the pi to be to start the study. I want to say he probably completed 90 of the study, and then, for various reasons, he had to move on.
Ryan Chartier: So just just to start.
Ryan Chartier: this project is very much a collaboration between Rti and our partners in Southeast Asia.
Ryan Chartier: Namely, A/C. Air and Esrc. Out of Chiang Mai University, the National University of Laos, the center for Environmental monitoring and modeling out of Vietnam. I believe it's the Vietnam National University, and then it as Adam had mentioned previously, is the National Astronomical Research
Ryan Chartier: Institution of Thailand, I believe, is the the full acronym
Ryan Chartier: and just the disclaimer. This project was funded by the Department of State. But any opinions or just discussions here are my own
Ryan Chartier: just to start a big thank you to the Acc leadership team. As I mentioned, Prakash was the Aqc. Lead for the majority of the study. He is now at Wri in India. So hopefully, some of us will be able to collaborate with him again in the future. Sam Porn, was the the Thailand Lead Hung, formerly of Cemm, was the lead in Vietnam.
Ryan Chartier: He owes the Lao lead, and then Ron was our collaborator at Narit, responsible for some of the emissions modeling that took place.
Ryan Chartier: so, as most of us know, exposure to high levels of air pollution is associated with a number of adverse health outcomes with it being the fourth largest risk factor for early mortality. And unfortunately, almost a hundred percent of the population and southeast days are are exposed to air pollution levels above WHO. Recommendations.
Ryan Chartier: And this results in over 2 million premature deaths. Although this number from who does include India and Bangladesh, so it's little weighted towards them. But I believe the latest numbers I've seen for Southeast Asia is greater than 300,000 premature deaths annually due to exposure to elevated levels of air pollution.
Ryan Chartier: And, as Adam had mentioned, yeah, air quality monitoring is essential to understanding the spatio temporal trends associated with the high levels of air pollution as well as predicting where that air pollution is going as as it doesn't know borders and then working to mitigate exposure amongst the population.
Ryan Chartier: So some of the the main objectives of our Aqc. Project were to one engage stakeholders from Academia non-governmental organizations, governmental organizations and then work to build air, quality, monitor and capacity in Southeast Asia.
Ryan Chartier: which included the deployment of low cost sensors throughout the region.
Ryan Chartier: We're also working to expand public awareness
Ryan Chartier: and provide educational materials, to, to people, to educate them about some of the hazards associated with elevated levels of air pollution.
Ryan Chartier: And then our
Ryan Chartier: overall goal is just strengthen the air quality, monitoring capacity in Southeast Asia and then expand awareness of of the issues associated with with air quality.
Ryan Chartier: So we've deployed approximately a hundred low cost sensors in Southeast Asia, mainly in Thailand, Lao, and Vietnam, and the majority of these sensors were purple air, Pm. 2.5 monitors sourced from the United States but we also deployed some dust point monitors that come from Cmu and Thailand, and that allowed us to do some inner comparisons between devices and kind of harmonize some of the data.
Ryan Chartier: We have. Pm, 2, 5. Data available, some, some of the locations. We have starting as early as 2020. And then our last data download was this past January?
Ryan Chartier: So
Ryan Chartier: when we first started this project, purple air data downloads were free and open access. Anybody could go into their system and download air quality data from any of the sensors
Ryan Chartier: that has changed over the course of the project. There's now a pay wall up for Eddie.
Ryan Chartier: Non, us deployed sensors.
Ryan Chartier: Fortunately, some of those data are still available through other sources, such as IQ air and open a queue which are continually pulling low, cost sensor data from other locations, and then compiling them and
Ryan Chartier: their own platforms.
Ryan Chartier: and part of the the study was calibrating the purple air and dustboy sensors against a pollution control department reference monitor in Thailand.
Ryan Chartier: So we we did a long term co-location deployment.
Ryan Chartier: and we use the the
Ryan Chartier: the reference data against the low cost sensors to develop calibration curves for the low cost sensors.
Ryan Chartier: And then we applied that to all of the purple air and dustboy centers, sensors that were deployed as part of this project.
Ryan Chartier: And so these these data are not currently available through any of the online platforms. But I'm happy to provide them upon request.
Ryan Chartier: I don't know if you can see my mouse 1 s.
Ryan Chartier: So there was
Ryan Chartier: great spatial spatial coverage in in Thailand, amongst the Pcd. Monitors, as well as the dust boy network.
Ryan Chartier: Laos and Vietnam had very few low cost sensors at the beginning of this project. We can see on this plot here. This is a plot of some of the the purple air sensors we've deployed. So we've worked to fill in some of the the spatial gaps in Southeast Asia.
Ryan Chartier: and this meeting
Ryan Chartier: is rather timely. As Chiang Mai has recently had
Ryan Chartier: been number one on the list of worst air quality in the world, according to some metrics. So this. This top plot up here comes from from IQ air
Ryan Chartier: and which is a
Ryan Chartier: pretty pretty good platform. If you haven't looked at it. It incorporates low cost, sensor data, meteorological data as well as data from NASA satellite. So you can. Also, you can see and pseudo real time where there are active fires burning.
Ryan Chartier: So if
Ryan Chartier: it's difficult to see on here, on, on this map here. But if you zoom in, there are active fires covering most of the Southeast Asia region at at
Ryan Chartier: yeah, currently. So unfortunately, I know you are all experiencing pretty pretty terrible air quality at the moment, so that just helps highlight the need for addressing this
Ryan Chartier: as there's no real good way to mitigate it on the personal level at the moment.
Ryan Chartier: This this
Ryan Chartier: bottom figure on the bottom right is from the the purple air map, and so you can't really see the numbers. But I think most of us are familiar with the color codes of the Us. Air quality index. And so you can see lots of lots of reds and purples.
Ryan Chartier: and I believe when I last checked the website. Hanoi had made it onto the to the top 10 list as well. Unfortunately, so all of these sensors are active. They're up and running. The data are available for people to use.
Ryan Chartier: Even though this project is ending, the sensors are going to remain deployed and active for for as long as we can maintain them, and we're happy to hand over maintenance to other folks as well. If there are projects that could utilize these sensors. Being in the Us. There, there's not much I can do to upkeep these sensors. But that maybe that's part of a a larger discussion, for later on
Ryan Chartier: part of the project is also engaging with stakeholders. So the the Aqc. Team, specifically, the country leads, have held a number of meetings, attended conferences and workshops to to help educate. You know, various stakeholders and network with other researchers interested in addressing air quality in Southeast Asia.
Ryan Chartier: We've also developed some educational materials. Over on the right. Here, you can see this is a pamphlet we developed with some educational information just
Ryan Chartier: giving background information on on what is their pollution? What are the components that we care about? What are the sources and some actionable steps that people can take to reduce their exposures. We've also developed 2 educational videos. I believe we may be viewing one of these part of the meeting.
Ryan Chartier: all of these materials are freely available. If they're useful to you, please feel free to download the Youtube videos, send out links, post your social media. Just use them as part of your arsenal of educational materials when discussing air quality with with various stakeholders.
Ryan Chartier: And I do believe there is a an air quality awareness week coming up in May.
Ryan Chartier: So if these materials would be useful in any way, shape or form, to support any efforts you may have ongoing to during that air quality awareness week please reach out.
Ryan Chartier: So in today's workshop. I think I mentioned this earlier, but we have 6 presentations planned. We'll have at least one presentation from each of our partner countries. While Pdr. Vietnam and Thailand
Ryan Chartier: the presentations will last for about 15 min with 5 min for questions.
Ryan Chartier: I know.
Ryan Chartier: Generally presentations tend to go over the allotted time limit. We'll we'll try to keep on schedule as best we can, but I don't plan to cut anybody off. If there's, you know, a valuable discussion going on.
Ryan Chartier: the presentations will be in English. Just for simplicity. But any of the attendees feel free to ask questions in your native language, and and somebody will translate that prior to the presenter answering.
Ryan Chartier: I I do plan to send out a list of attendees for networking purposes. If you're interested in being on that email list at some point during the workshop, please put your name, Institute title and email address into the chat. I'm not going to use the the registry. So if you're on the registry you registered for this workshop and don't want to be included. Then just don't enter your email into the chat. We'll solely use what's on the chat?
Ryan Chartier: so what I'm hoping to get out of this workshop. We're going to highlight some of the ongoing air quality work from our re colleagues in Southeast Asia. That way. Everybody is aware of some of the ongoing research in the area, and then we can hopefully network either towards the end of the the workshop or offline as needed.
Ryan Chartier: I think it's an important forum. Yeah, we're we can have some open discussions about air quality in Southeast Asia and suggestions for S. Steps to address some of these issues.
Ryan Chartier: The discussions are going to be towards the end of the workshop.
Ryan Chartier: So let's try to keep any questions related to the specific presentations, for now and then we'll have more of an round Table open discussion towards the end of the workshop.
Ryan Chartier: As I mentioned, networking amongst the various researchers on the call, both during the workshop, now and then offline following the workshop is important, and I'm happy to facilitate any of those conversations going forward. I may not be parts of the part of those conversations. Just do the due to the time differences, but I'm happy to put various people in contact with other attendees.
Ryan Chartier: It's a quick overview of the agenda we have. I'm going to wrap up in the next minute or 2 and then I believe Cmu is gonna show one of the educational videos that they develop help develop as part of this project.
Ryan Chartier: And then we'll continue with Matt Perkins with the the next presentation.
Ryan Chartier: The last 30 min or so, if we're on schedule, will be kind of an open, ended discussion. I have some pre planned questions to to start us off, but.
Ryan Chartier: as I had mentioned previously, I I have an appointment at about 6 Am. My time. So I'm going to try to hop off this call at about one am. Just so I can hopefully get a couple of hours of sleep before I start my day. But Sam Porn or one of my other Apc colleagues, will be able to run the discussions if I need to leave.
Ryan Chartier: and then, before we hop into the presentations, a big thank you to the State Department, one for their funding, but all of the support they've provided throughout the course of this project. There've been multiple people involved. But I'll just
Ryan Chartier: that say, thank you to State Department staff as well as the the other grantees working in this area. They've been very helpful and accommodating as well with any questions.
Ryan Chartier: the Aqc. Team. So I I introduced some of the country leads, but they didn't work in a vacuum. They have their their teams that helped out from with everything, from logistics to deployment of sensors, which is not a trivial task in some of the locations where we deployed sensors. They're they're very remote. So it was very time consuming process.
Ryan Chartier: and then, thank you in advance to all the attendees, please, if you can try to be an active participant in the discussions, I think you know, the more people involved in the discussions, the the better information we'll be able to have to help formulate plans for for moving forward
Ryan Chartier: and don't hesitate to contact me with any questions. My email address is there my phone numbers there. And if you're on the list of folks
Ryan Chartier: willing to communicate via email after the the workshop I'll be Ccd there as well.
Ryan Chartier: And we have any questions before we move on to the next section of the workshop.
Ryan Chartier: Okay, Cmu, did you? Wanna
Ryan Chartier: play one of the videos.
Ryan Chartier: I believe we were just planning to show one video correct.
Somporn Chantara: Yeah, sure, we are ready to do that just a moment, please.
Somporn Chantara: Clean air is vital for living things around the world.
Somporn Chantara: whether it's humans, animals, or plants.
Somporn Chantara: However, the air we breathe contains contaminants that can harm our health.
Somporn Chantara: The air pollution derives from various sources, including the open burning of agricultural residuals and forests, as well as vehicle, exhaust emissions, industrial emissions and construction activities.
Somporn Chantara: One of the air pollutants that can affect human health is PM. 2.5 PM. 2.5 or fine inhalable particles with diameters that are generally 2.5 micrometers and smaller. How small is 2.5 micrometers. Imagine about our hair.
Somporn Chantara: The average human hair has a diameter of around 70 micrometers, which means it is 30 times bigger than the largest PM. 2.5
Somporn Chantara: pm. 2.5 can be emitted directly from the source or produced in the air as the result of chemical processes.
Somporn Chantara: These, Pm. 2.5 are carried thousands of kilometers by the wind.
Somporn Chantara: PM. 2.5 particles can enter the lungs and lead to short-term acute health effects, including coughing, asthma, and various respiratory and cardiovascular disorders. Some of these conditions may result in acute effects. Furthermore, long-term chronic exposure to air pollution can increase the risk of serious conditions, such as stroke, heart disease and lung cancer.
Somporn Chantara: Therefore it is crucial to effectively manage air quality at the national.
Somporn Chantara: regional, local.
Somporn Chantara: and even individual levels. To mitigate these risks.
Somporn Chantara: therefore, we started to hear quality monitoring capacity in Southeast Asia or Hqc.
Somporn Chantara: Which is funded by the Us. Department of State in order to support the installation of a well-tested low-cost Pm. Sensor
Somporn Chantara: in 2,021 Rti International's Research team in collaboration with Chiang Mai University, Thailand
Somporn Chantara: Research Center for Environmental monitoring and modeling. Vietnam.
Somporn Chantara: a national University of Laos, began supporting local stakeholders in installing the low-cost Pm sensors in Thailand Vietnam and Laos.
Somporn Chantara: We aim to develop a network of low-cost Pm. 2.5 sensors to cover a greater area and also raise awareness and concerns about air pollution at local and regional levels. As a result, the A. Qc. Project has expanded its network of low-cost Pm. 2.5 sensors to 3 countries, Thailand, Laos and Vietnam.
Somporn Chantara: Such data is beneficial to local stakeholders
Somporn Chantara: for further details about the first workshop and the locations of sensors along with additional resources, make sure to check out the links provided there you'll find in-depth information, useful links, and more
Somporn Chantara: a.
Ryan Chartier: Great. Thank you. Some foreign not upon, or some foreign as we're talking. Can can you drop the Youtube links into the chat just in case people are interested in seeing the videos. I don't think the QR. Code was up long enough for for people to be able to take a picture.
Nuttipon Yabueng: Sure, and before we start the the next sections, could you please download the blackout zoomed on in the chat, and then we will have the referral together before we start the next sections
Nuttipon Yabueng: alright, and please turn on the camera, and every stop will take a picture
Nuttipon Yabueng: for a short minute
Nuttipon Yabueng: alright.
Nuttipon Yabueng: And everyone please turn on the camera we would like to have. So for that together today.
Nuttipon Yabueng: Okay, if ever stop ready, you can make assigned to take a photo? Right?
Nuttipon Yabueng: A.
Nuttipon Yabueng: The first, the first quarter.
Nuttipon Yabueng: 1, 2, 3,
Nuttipon Yabueng: a
Nuttipon Yabueng: I
Nuttipon Yabueng: and
Nuttipon Yabueng: the second one.
Nuttipon Yabueng: 1, 2, 3.
Nuttipon Yabueng: Okay.
Nuttipon Yabueng: the moment.
Nuttipon Yabueng: Hey?
Nuttipon Yabueng: Okay.
Nuttipon Yabueng: thank you very much.
Ryan Chartier: Thanks everybody.
Ryan Chartier: Matt, I think you're up next I was that when I was reviewing your slides I saw you had a few discussion, questions or items at the end. Are you planning to stick around for the full workshop, or is that something you'd like to address at the end of your presentation?
Matthew Perkins UN ESCAP: Whatever is more suitable from your side.
Matthew Perkins UN ESCAP: I can do heather.
Ryan Chartier: Okay, maybe we can hold off until the discussion section. If if you're planning to be here
Ryan Chartier: perfect. Thank you. Go ahead whenever you're ready.
Matthew Perkins UN ESCAP: Okay. Great.
Matthew Perkins UN ESCAP: Yes. So thanks everyone for having me here today. I'm really excited to join this workshop. It's it's great to see some new faces, and also folks that we have been working with for some time and be be back in this community. I'd like to go through S. Capps activities on air pollution and findings that could help support the work of this group moving forward. Our primary framework as an intergovernmental organization is the regional action program on air pollution.
Matthew Perkins UN ESCAP: We were very excited to have all of our 53 Member countries endorse this action program in December of 2022 and provide that regional, coordinating instrument among the countries to promote the science based policy. So I'd like to highlight a couple of ways that that can intersect with the work we're discussing here.
Matthew Perkins UN ESCAP: We moved directly from signing the agreement to implementation. I've summarized a couple of the events and and interventions that we've had since that time. This is included both, you know, high level political events as well as tangible and local interventions to promote change
Matthew Perkins UN ESCAP: under that umbrella scap is currently coordinating 4 projects that would involve the countries on this call related to air quality. Those obviously have a an array of activities associated with them, and we would be very enthusiastic to cooperate with folks on those moving forward
Matthew Perkins UN ESCAP: so to to frame the the discussion. Today, I've pulled out a couple of insights that we would like to highlight in ways to approach the air pollution problems in Southeast Asia and in and in these particular countries, specifically
Matthew Perkins UN ESCAP: as from our prior work, we had, built a a data warehouse and applied machine learning to data sets in our focus countries like to pull out these working results that we had for the city of denying in which we were looking at how to harmonize the readings from the ground based air pollution sensors in the context of updated gaps, calibration and and other components that impact that data. We
Matthew Perkins UN ESCAP: we're able to have a highly successful results in adding more insight to the available data in that context.
Matthew Perkins UN ESCAP: Likewise, we were able to determine that by digging into the existing data in new and different ways, that meaningful insight could also be obtained for driving forward with interventions. Here's 2. A examples of that the top graph is one that I think folks would be intuitively quite familiar with. It's just a raw count of remote sensing detected hotspots a annual average for the last 15 years represented
Matthew Perkins UN ESCAP: it by month.
Matthew Perkins UN ESCAP: So this well captures the kind of seasonal variances that we typically see among the comp countries in Southeast Asia and their approaches to to biomass burning
Matthew Perkins UN ESCAP: in this context, it
Matthew Perkins UN ESCAP: examining the data, not just from a count of the total number, but also from a understanding of the size of the individual fires brought new perspectives to where to focus action, as in some countries it's quite clear that they're they may have a certain number of of biomass burning sites, but they may be much smaller. This is very helpful in understanding how to target interventions for total impact.
Matthew Perkins UN ESCAP: Additionally, by looking at patternicity, for where fires are occurring at the same location, repeatedly across multiple seasons helps 0 in on distinguishing the difference between man-made fires and fires that may be naturally occurring wildfires which would obviously benefit from a different type of intervention. So these are all new and helpful perspectives that can come from the same data sets by applying new data science techniques to understanding the the situation.
Matthew Perkins UN ESCAP: Likewise, we, we note that this approach is becoming much more
Matthew Perkins UN ESCAP: necessary an increasing use of machine learning and advanced data. Science techniques in these applications can be seen across projects and interventions. The particular example that I have on the screen now is related to dealing with remote sensing data from the gem satellite platform in order to obtain near real time air pollution data throughout Southeast Asia.
Matthew Perkins UN ESCAP: so that the need to move towards and and mainstream data, science and machine learning and air pollution work is more clear than ever before.
Matthew Perkins UN ESCAP: In this regard we assisted a number of cities in Southeast Asia in creating data, driven city level air pollution action plans, including Shanghai and a number of those cases we held on the ground workshops and coordinated with the the beneficiaries and stakeholders there, some of which are are on this call. Now, in order to help focus the science into action locally
Matthew Perkins UN ESCAP: in terms of potential opportunities that this organization of this group of people may be most interested in. I'd like to highlight these results from one of S. Capsa partners, Adpc. That are supporting the surveyor. May Kong intervention that was mentioned previously. We were very enthusiastic to see the results of their innovative work here in combining remote sensing data with
Matthew Perkins UN ESCAP: specific types of research grade ground instruments to determine the viability of the available data on particularly pm, 2.5,
Matthew Perkins UN ESCAP: in that context, we considered their re results to be extremely encouraging being able to demonstrate reli reliability through our squared values of between point 8 2 and point 8 9 particularly for an area of the globe that has comparatively fewer research grade sensors we were very encouraged by this result, and believe it will be very helpful in moving forward
Matthew Perkins UN ESCAP: forward to action in these countries as we move forward. So I wanted to highlight this as a particularly useful tool that the participants in this call may be interested in.
Matthew Perkins UN ESCAP: So in terms of this section of my presentation, these are the 3 real takeaways that we would like to to underline the need for the machine learning data science approach to the data sets that we're dealing with in in Southeast Asia.
Matthew Perkins UN ESCAP: The need to understand the full data life cycle of where machine learning is coming into play by third parties and the data that they're providing and to highlight that we really do have policy, relevant action, oriented conclusions that can be drawn from this data. If we use these methodologies to examine what we have
Matthew Perkins UN ESCAP: and in that regard I would like to sort of respond to something that that Ryan had highlighted earlier. You know, we really do feel that the sustainability of low cost sensor networks is an important component. We know that our colleagues at Cmu and Cmru have been very involved in that. I think there would be a real opportunity here for S. Cap to be able to help support the sustainability
Matthew Perkins UN ESCAP: of those sensor networks as well as you know, preserve and keep alive the data and data sharing there. So I hope that we could have a 2 way or potentially 3 way conversation after this to discuss some tangible options for taking forward the important work
Matthew Perkins UN ESCAP: that that that your intervention has done so far.
Matthew Perkins UN ESCAP: So with that being said, I'd like to highlight a couple of areas that we feel are opportunities for emerging perspectives on the next steps for air pollution in these countries.
Matthew Perkins UN ESCAP: In particularly, we we've been impressed by work on socially differentiated policy impact. I've extracted a couple of examples here from this recently published study on the need to combine the machine and data side of air pollution science with the way it's impacting people on the ground.
Matthew Perkins UN ESCAP: particularly in the pro in the prism of vulnerable populations people struggling with poverty and and so forth, which, of course, would be directly relevant to the human impact of what we've been seeing in in the data so far.
Matthew Perkins UN ESCAP: So in this regard, I'd like to highlight that one of the particular dimensions where this aspect shows very clearly is in the need to
Matthew Perkins UN ESCAP: understand how policies around clean cooking and clean vehicles affect people at different parts of the income structure, and that in some cases these policy interventions can actually be quite harmful depending on the, you know, total intersectional picture of the people who are being impacted on the ground. So in the interest of time
Matthew Perkins UN ESCAP: I'll just highlight that S. Camp is moving forward with mainstreaming a socially differentiated approach to air pollution, policy, action, and has done a preliminary data inventory of all of the of the countries. And in our definition of Asia in the Pacific that make this data available. It appears to us that, Vietnam, for example.
Matthew Perkins UN ESCAP: does publish the household income data necessary to support this type of analysis. In the case of Lau, we were able to identify some of the data sets necessary, but not all and would hope to continue to cooperate with the people on this call, moving forward to make sure that we really can have that kind of analysis, to make sure our policy interventions are well founded.
Matthew Perkins UN ESCAP: So I think impacting illustrating some of the the harmonies and and perspective that we're seeing and and the different actors. I would like to to highlight a couple of of
Matthew Perkins UN ESCAP: points in this regard one being the need to move away from a geographic boundaries, political boundaries, perspective, and towards an an air shed perspective to emphasize the you know, the shared code benefits approach and and really take a very science centric approach to understanding. Where the emissions coming from, where are they going, and who are they impacting? And and we're pleased to see more and more uptake of this type of perspective
Matthew Perkins UN ESCAP: among policy makers in the region. We're very hopeful that scientific experts such as yourselves can play a vital role in helping to reorient people's thinking around the need to cooperate in air sheds rather than
Matthew Perkins UN ESCAP: looking at a line on a map
Matthew Perkins UN ESCAP: in this regard. Here's kind of an example of some things happening in the region. This particular one from India, which, we think is, is very valuable because it is taking this. This air sheds approach, as you can see in the the lower right hand section, they're tracking, incoming emissions from other urban centers that share the air shed of this particular city. So the science here is really what we think is is leading the way.
Matthew Perkins UN ESCAP: And I think we all have some thinking to do around how this information is represented and shared in order for it to be persuasive and and really prompt action. So we do see
Matthew Perkins UN ESCAP: local action in the region that we think can be mutually beneficial across the countries in Southeast Asia.
Matthew Perkins UN ESCAP: I noted that that Adam mentioned. This intervention, I would also like to to highlight it. I think it's a a great case study and international cooperation on advancing air pollution science this particular mission, which I think takes gives us some great insight into how the air shed in this area is performing is, is quite valuable. And and we look forward to analyzing the data from that.
Matthew Perkins UN ESCAP: This type of cooperation is something that scap really wants to support moving forward.
Matthew Perkins UN ESCAP: I'd also like to highlight this example of of how this model has been successfully deployed elsewhere. For consideration in the air sheds we're dealing with. Which highlights how the thinking moved from political boundaries to scientifically
Matthew Perkins UN ESCAP: created perspective the air sheds and then overlaid with the human needs of the vulnerable populations in those areas. We feel strongly that this process to combining air shed science with social impact is really the way forward
Matthew Perkins UN ESCAP: most recently, we were impressed with this published scholarship which gives a great breakdown of how to apply an air shed centric perspective in both data, rich and developing country environments Scap expects to use this type of scholarship as a keystone in moving forward with our future interventions in the Sabra region.
Matthew Perkins UN ESCAP: In that regard I'd like to briefly highlight these particular priorities that we would like to move forward with in in Southeast Asia. The project that we will be implementing on air sheds contains several key components. We would like to be working directly with 3 multi country air sheds in Southeast Asia. I'm happy to confirm that our
Matthew Perkins UN ESCAP: official letter, seeking expressions of interest from the pertinent Ministries of Environment has already been sent out. We've received a number of responses and we'll be following up with a couple of the other countries in in Southeast Asia. I think it
Matthew Perkins UN ESCAP: this stage I have to be a bit strategically ambiguous until agreements are officially signed. But several of the countries in this room have expressed interest, and a few have not, so we would like to be able to to work with all of you to encourage your policy makers to participate in this project.
Matthew Perkins UN ESCAP: It has a strong data sharing component the drafting of air shared cooperation agreements. And key things that we think will really move things forward as as well as providing resources financial resources for company countries to implement their
Matthew Perkins UN ESCAP: air pollution priority interventions throughout the the 3 Year project term. So with that being said, I'd like to also highlight some of the related matters that scap has coming up for everyone's awareness. We are currently supporting 2 open ended working groups on air quality standards and one on data. This is the
Matthew Perkins UN ESCAP: schedule of meetings for those working groups. Those would be. Those are open for their participation of all of the persons on this call if you would like to participate and receive an enter an invitation to that. Please let me know, and we'll be happy to to loop you in on that. The recommendations from these working groups will form a policy paper that will be sent to our Member countries this
Matthew Perkins UN ESCAP: fall for their consideration and informing their their future action. So we hope that we can continue to work with you folks on the working groups and and other related interventions. We also are producing a a number of of studies and upcoming events that we would love to be able to collaborate with with you on so in light of the time I'll leave it there.
Matthew Perkins UN ESCAP: But look forward to a lively and and fruitful discussion as we move forward today. So thank you very much.
Ryan Chartier: Thank you, Matt. Are there any questions?
Ryan Chartier: I have a question.
Ryan Chartier: maybe hypothetical, but I I like the air sheds approach. I think it's been successful in the past and can be successful here. You mentioned providing funding to the participating countries.
Ryan Chartier: How how would that be divvied up? Would it be by the area of greatest need or the potential for the greatest improvements in health.
Ryan Chartier: or would funding be prioritized for the areas where decrease in air pollution is most achievable, or some combination of all the above
Ryan Chartier: you're you're muted, Matt.
Matthew Perkins UN ESCAP: Drink some combination. We have a set of selection criteria which I'd be happy to go over. I don't think I could necessarily do it within the the available time. But we have a basket of indicators that we use to to focus that funding and that will be done in in a dialogue with the the beneficiary countries as as we move forward.
Matthew Perkins UN ESCAP: Okay.
Ryan Chartier: Any other questions from anybody else at this point.
Ryan Chartier: Okay, thank you, Matthew. It sounds like you would benefit from
Ryan Chartier: an email list of the attendees here for communicating with further. So just a reminder, every anybody who's who's willing to be on that email list. Please put your information into the chat.
Ryan Chartier: So I'm porn. I I think you are next.
Somporn Chantara: Thank you, Ryan.
Somporn Chantara: Let me share
Somporn Chantara: my screen.
Somporn Chantara: Hey? Did you see it? Right?
Somporn Chantara: Good morning, everyone.
Somporn Chantara: My name is Sam Pontara from Jomal University. My talk today entitled The Research Activities and Academic Services concerning our pollution in Northern Thailand.
Somporn Chantara: So I think most of you know that
Somporn Chantara: at this time it's a peak for the air pollution in Southeast Asia, particularly in the upper part of the region. So this picture can give you an overview about how bad the air pollution can be in this region.
Somporn Chantara: and this video also show the birth. I will option my city on 15 of February, on the plan on the way from Shanghai to Bangkok we can see very clearly the different between the
Somporn Chantara: the air inside basin and the above.
Somporn Chantara: Normally we have a very nice view from the top of the mountain, like you can see in the left hand side.
Somporn Chantara: but in this season we cannot avoid it. It still happen from year to year.
Somporn Chantara: And this is a data from Pollution control Department and Quality monitoring station in geomicity.
Somporn Chantara: It's showing average 24 h pm. To 5 5 concentrations in shy my city.
Somporn Chantara: And the data was starting from 2,018 to now.
Somporn Chantara: So you can see that every dry season from February to April, we still have very high concentration of Pm. 2.5 into my city, and it's much higher than the national standout. Now they be used. 37 microgram per cubic meter.
Somporn Chantara: The highest concentration
Somporn Chantara: was found last year in 2,023, and for this year it's still
Somporn Chantara: on the way to go. So the data I have now is that over 1 50 microgram per cubic meter for their daily average concentration.
Somporn Chantara: And from this
Somporn Chantara: slide you can see the Trans battery air pollution, the distribution of PM. 2.5 generated from the active fire Hotspots using the Vafen model
Somporn Chantara: run vital the chocolate. One of my colleagues at Cmu. So, as Mitch Matthew already mentioned about the Si approach, I think from this slide we can see very clearly why we have to work together to solve the problem, because even the source of the application are generated in another places. What you still can
Somporn Chantara: can get the impact from that because of the air has no battery.
Somporn Chantara: So this show the data from 2,021, but it's almost the same for every year.
Somporn Chantara: More data on 5 hotspots in Southeast Asia.
Somporn Chantara: So I highlight 5 countries in this graph.
Somporn Chantara: including Vietnam, Cambodia, Lao, Thailand, and Myanmar.
Somporn Chantara: So each year we also have the same problem with the air pollution because of the open burning. The red color you see in the map is the active fire. Hotspots be detected from the satellite
Somporn Chantara: from the Via system. So each year we have less burning. Some year we have more burning. It depends on the climate condition as well. For example, any year online in the idea with Maureen or less rain.
Somporn Chantara: And this is the data of the active fire counts
Somporn Chantara: from 2,018 again until now.
Somporn Chantara: But this year we have the data only up to 14 Marsh.
Somporn Chantara: So you can see that most of the burning occur in Myanmar and also in Thailand and Laos.
Somporn Chantara: So we have to figure this out
Somporn Chantara: for this year. Our pollution in Chiang Mai City.
Somporn Chantara: We also collect the
Somporn Chantara: PM. Samples every year, and I would like to show to you how it changed from the first of February this year until the seventh of March.
Somporn Chantara: so you can see the change of the sky and also the the colors of the samples. So we collect the samples, and we can differentiate it from the the doctor of the of the black color here. So it
Somporn Chantara: it's starting from very low concentration, like 15 microgram per cubic meter up to the very high 122 microgram per cubic meter of PM. 2.5 concentrations.
Somporn Chantara: So we come up with the summarize that the factors that affecting the air pollution in Northern Thailand can be these 3 main factors. The first one is the geography, because our location is slotted by High Mountain, so most of the cities in northern Thailand are located in the basin, so this flavor to the pollutants to
Somporn Chantara: accumulated in the basin. The second factor is also the natural one which is the meteorological factors. For example, wind temperature, inversion. So these factors can also pause the serious app pollution. If we have a high pollutants in the area.
Somporn Chantara: and the last factor is the source of air pollution. The most important source in our region is the open by mass burning, even though in the big city we also have the problem of the transportation which emits also amount of air pollution. But this factor can be controlled. And we think that if we are focusing on the source control it would be better in the future
Somporn Chantara: talking about the Accc activities, as Ryan already mentioned, about the objectives of that of the project for us, I think that the most effective way is to train and to educate the stakeholders.
Somporn Chantara: and how to build the capacity in equality management.
Somporn Chantara: We also apply the local sensors that we obtain from the us the purple air and the one that we have
Somporn Chantara: in Thailand originate from Shomi University. That that's why we have more locations in Thailand. So from from this we can also obtain valuable data.
Somporn Chantara: And this is our Shanghai University team
Somporn Chantara: myself. Dr. Said Dr. One, Dr. Nathan, Dr. Paul Park, and our supporting team, Miss Peter Moon, Drisam and Miss Yusia.
Somporn Chantara: We have launch the project in 2,021, and we have lots of activities. After that. This is some of activities that I would like to show the exhibition that we launch during the Ted Xian. My event in J in November 2,021 at the Shanghai.
Somporn Chantara: So we also we. We have lots of visitors, and one of that is Mr. Shawn O'neil, the late A. Consult general from the Us. Consulate in Jian mind.
Somporn Chantara: We also join many seminars, and this is one of them
Somporn Chantara: the Seminar and exhibition organized by the Norton Brace Council during March 2,02022 in January as well.
Somporn Chantara: and this one is the activities
Somporn Chantara: in January
Somporn Chantara: exhibition on and even sharing the Thailand Us. Experiences
Somporn Chantara: a path through cleaner and healthier communities 5 ways to develop clean air between Thailand and the Us. Co-hosted by the Us. Mac home for future program
Somporn Chantara: and the major organizer is the Us. Consulate in January, so I myself and Doug say also keep a lecture on the source of the air pollution in Northern Thailand.
Somporn Chantara: and another event being we have several meetings with Dr. Yvon Bing, the Us. Fellow and representative from the Us. Embassy in Bangkok and us consulate in Jiang
Somporn Chantara: in December 2,022, in March, when 2,023, and also I have a chance to meet with the deputy director, Miss Sarah Quincy, the from the Us. Embassy in Bangkok, and the team in August 2,023. So we have discussion Major, on the evolution in the region and how our activities can support
Somporn Chantara: the Governor to to manage the equality.
Somporn Chantara: And these are some of the examples
Somporn Chantara: that we have in our project.
Somporn Chantara: like the accus brochure for the introduction part and the educational material, as Ryan already mentioned in his talk.
Somporn Chantara: And now let's move to the research activities as team you.
Somporn Chantara: So we have the Equality Monitoring Station
Somporn Chantara: at the rooftop of our building here inside a Cmu.
Somporn Chantara: so we can observe the changing of the sky
Somporn Chantara: by taking some pictures, and we also collect the samples like the Pm samples, using the several equipment. For example, these our samples that we have
Somporn Chantara: every year, using the high volume as sampler, low volume, or Mini volume as samplers.
Somporn Chantara: We also collect the size fractionated Pm samples using the cascade impactor.
Somporn Chantara: So these are the examples of our samples before we do the analysis further in the lab
Somporn Chantara: and assess the health impact and also the impact on the environment
Somporn Chantara: for the activities and community-based projects. We have some projects to show to you as well.
Somporn Chantara: So we have several meetings with the Permanent Secretary of Higher Education, Size, Research, and Innovation, and the Committee of the National Research Council of Thailand.
Somporn Chantara: and also the office of the Public Sector Development Commission on Air Pollution management. So they come to visit us at my university, and we show them our facilities and our past research projects, and also the ongoing projects.
Somporn Chantara: I also have a chance to meet with the Prime Minister of Thailand. 2 times in November last year I did the presentation about the activities of same you and supporting role to show my governor and stakeholders on air pollution management.
Somporn Chantara: And the previous, the just, just the current one in March.
Somporn Chantara: So I present on the situation and source of evolution in Northern Thailand, and possible solutions to the Prime Minister. So I hope that our work can also support and help
Somporn Chantara: the way to solve the problem in the near future.
Somporn Chantara: We also have some communication channel with the stakeholder using the live official
Somporn Chantara: because, it's quite popular in Thailand. So that's why we come up with this option. So if you add friend, with us so you can, you can check the air quality in your area by sharing the location. And importantly, you can also check the
Somporn Chantara: the equity in advance, like the forecast for a next few days. So it's quite easy to use, and it's very informative. You can also fly the safe zone that you can stay during the
Somporn Chantara: the one either way, that you want to go out and spend some days.
Somporn Chantara: We also have the project so called Cmu model. This project is the initiative project to reduce the PM. 2.5 emission from open burning for sustainable development goals at but village in Shanghai Province.
Somporn Chantara: The object tips of the project are to improve the quality of life of the people to reduce the open burning
Somporn Chantara: and to prevent the health impact of the people. And last, but not least, to create a prototype area for such sustainable communities.
Somporn Chantara: So we have done lots of sub projects in the village, together with the people in the village.
Somporn Chantara: for example, we have 4 types of projects
Somporn Chantara: under the economic and quality of life, development, environment, public utility, social and public health.
Somporn Chantara: So the project was launched already. 3 years, and we already finished the project, and we hope that we can continue this kind of project in the next area.
Somporn Chantara: But the question still remain.
Somporn Chantara: if we already done enough.
Somporn Chantara: we have we missing something, and what else should be done?
Somporn Chantara: And this is my last slide. Thank you very much for your high attention.
Ryan Chartier: Thank you. So important. Great talk. Does does anybody have any questions?
Ryan Chartier: I have a couple?
Ryan Chartier: one. I I see you're collecting the pm. On filters. It looks like.
Ryan Chartier: was it? Quartz filters?
Ryan Chartier: I'm curious. What? What are you analyzing for? Pahs, or something similar. And how does the chemistry change depending on where you are in the burn season.
Ryan Chartier: And then my second question is
Ryan Chartier: more related to me, being naive about the this area of the world having not been there. But in general, what do people do to protect themselves during hay season? From the Pm.
Ryan Chartier: I know some people work in office buildings. They may have filtered air, but in general I'm guessing that's not the case for most people. What what steps do they take to protect themselves from air pollution. And what steps would you recommend.
Somporn Chantara: Yeah.
Somporn Chantara: okay, for the first question about what we are analyzing our samples. So we have lots of parameters
Somporn Chantara: for analysis of our samples. For example, the Ph for the help risk assessment.
Somporn Chantara: And we also do the source analysis by analyzing water soluble ions
Somporn Chantara: or C and Ec. Using the carbon analyzer
Somporn Chantara: heavy metals.
Somporn Chantara: So these kind of parameters can be used for source analysis.
Somporn Chantara: Yeah? And for the second question, how do people protect themselves during the air pollution episode. So actually, I did not mention
Somporn Chantara: our activities. We also produce the PM. 2, 5, 5. Mask
Somporn Chantara: that can be useful for the people that living outside. So they should wear the mask to protect themselves, and they are off site. But inside a house we also have some kind of technology like future.
Somporn Chantara: the air inside a house and use the positive air to help decreasing the level of pollution inside the house. And the government also try to help, for example, into Microville Province. We also have the project. So call
Somporn Chantara: reduction of the dust. That's mean we try to increase the number of houses or the rooms in the public space, to equip with the equipment that can filter the air and do the pressure positive pressure room.
Somporn Chantara: So, so that's for helping.
Ryan Chartier: Thank you. Yes, I
Ryan Chartier: I know the hay season. It could be a problem. And here in the Us. When there's wildfires, I I know when the smoke gets it in homes, it actually lands on surfaces due to the high surface area in the homes. And it can undergo heterogeneous reactions. And you're you're still being exposed to the
Ryan Chartier: that.
Ryan Chartier: The smoke, or you know, one of the products of the smoke for for weeks and weeks after the event. So I imagine that's also an issue here following hay season.
Ryan Chartier: Be curious to see if
Ryan Chartier: if there's research in that area at some point. But it
Ryan Chartier: looks like, Matthew. You have a question.
Ryan Chartier: You're you're muted. If you're
Ryan Chartier: speaking.
Matthew Perkins UN ESCAP: Thanks. Yes, there's Lag getting unmuted. I do a couple of questions, and great to you Dr. Sam Porn,
Matthew Perkins UN ESCAP: and kind of adjacent to what
Matthew Perkins UN ESCAP: we've discussed here.
Matthew Perkins UN ESCAP: In terms of the future needs. I think we've had in the last couple of years significant resources identified for installing low cost sensors, but generally we'll track Pm. 2.5 and a. And a handful of other compounds
Matthew Perkins UN ESCAP: at this stage, looking at the map, it suggests to me that, particularly for Thailand, and potentially for its neighbors as well.
Matthew Perkins UN ESCAP: that low cost sensors would no longer be a top priority for answering the most important scientific questions I would suspect in the alternative that looking at things like heavy metal deposition, or more detail on the composition of the Pm. 2.5 compounds themselves, and and whether or not carcinogens are hitching a ride there due to previous types of pesticides and things like this?
Matthew Perkins UN ESCAP: Th, that we need more deep scientific insight rather than broad, low cost sensors. So if you could share your views on that, that would be great. Thanks.
Somporn Chantara: Hey? Thank you, Matthew. So, as you mentioned, yes, we have lots of local sensor. But for the
Somporn Chantara: detail
Somporn Chantara: of the what are inside the
Somporn Chantara: the Pm. For example, is still needed.
Somporn Chantara: For example, in some countries there's still not many publication or knowledge about that. In Northern Thailand we do have some research published in international level. So it's not that hard to find, but we still have to explore many topics. So I always talk to my colleagues that we still
Somporn Chantara: have to follow many lead countries to the deep size. So we still on the progress to develop ourselves.
Somporn Chantara: And we still need more funding and also more
Somporn Chantara: this assistant to help to do this kind of of research. For myself, I think we we have, some results on the source analysis, for example, in Zoom, my city. But we still have to explore this information for another places, and I do love to cooperate with our colleagues from another countries to
Somporn Chantara: expand our our research network. And I can send some of my research a paper to to you. If you like to have some specific titles on that, please let me know. Thank you.
Ryan Chartier: So important does Pcd. Do chemical speciation of of any at any of their collection sites? Or is it mostly academic institutes that are disposable.
Somporn Chantara: Yeah, most the universities are taking care of that. I mean, it's the research based.
Ryan Chartier: Okay, thank you.
Ryan Chartier: We have any other questions before we move on.
Ryan Chartier: Okay, why don't we.
Somporn Chantara: Another question, or which is.
Ryan Chartier: I think, his hands still up.
Ryan Chartier: so we'll we'll move on to our our second presentation from Thailand.
Somporn Chantara: Thank you
Somporn Chantara: upon you, unmute.
Nuttipon Yabueng: Oh, yes, just a moment, please.
Nuttipon Yabueng: I'm not down
Nuttipon Yabueng: alright. I
Nuttipon Yabueng: can. You see my screen now?
Somporn Chantara: Yes.
Nuttipon Yabueng: Gets
Nuttipon Yabueng: okay. Alright. Good morning, everyone. I am not the con yet from Chima University. Actually, we are the same team with the Dr. Sapon. Today, I would like to present and share some data about the health impacts in the topics of the associations of air pollutants and hospital admission in ching my thailand, which is quite specific with the health.
Nuttipon Yabueng: So
Nuttipon Yabueng: that.
Nuttipon Yabueng: Alright. Okay. Just talk a little bit on the situations of air pollutions in Northern Thailand. Actually, Dr. Someone have said before, this is the patent of the Daily Pm. 2.5 only into my city. We got a data from the Persian Control Department at you might for many years since 2,000 12. And this is the pattern you can see the high peaks of the Pm. 2.5 concentrations
Nuttipon Yabueng: with files in will files during the dry season in nought, since in Thailand during February, March and April, every year, and
Nuttipon Yabueng: every year the concentration. So pm. 2.5 or more exceeded than the national accuracy, stand out of Thailand, F. 50. Mega grand, we're keeping method. This, which is the the old one and since the ws of guidelines just rewind the guideline of air pollution of the
Nuttipon Yabueng: PM. 2.5 guideline. Here they reduced to 15 mega gram per cubic meter last year in Thailand. We also, at just
Nuttipon Yabueng: the Naaqs in Thailand, reduced to 37.5 microgram. Break cubic meter, and you can see it's still higher than the the new standards, right?
Nuttipon Yabueng: And this one is the the the things that we're organizations can find out. We call it key facts by WHO. Like Ryan, say, in in this presentation we found each year 7 million
Nuttipon Yabueng: early days result from the app pollution with many diseases here. So with the heart disease around 34% new media around 21% on also the stroke.
Nuttipon Yabueng: okay.
Nuttipon Yabueng: stork, and also the
Nuttipon Yabueng: codd, which is about the lung disease, long disease, and also lung cancer here, and unfortunately, around 4.2 million premature date worldwide, due to the outdoor pollution export shows.
Nuttipon Yabueng: And that's why we are interested in the impacts of the air pollution, some health. And for this one in Thailand also, we try to concern about this impact. So this information I got from the Ministry of public health. They focus on the civilians of the disease caused by the Pm. 2.5. They just cratified into
Nuttipon Yabueng: for Diseases Group. This is group like a respiratory disease, heart disease and stroke consentibilities, and also the martyrs.
Nuttipon Yabueng: These 4 groups here and then.
Nuttipon Yabueng: We have a study sites which collect the Pm. 2 pi. And try to analyze the chemical compounds that specifically for the toxic compound and try to summarize and try to analyze the data together, and I would like to show you the study signs of us. So we have 2 studies that in my in my province which represents
Nuttipon Yabueng: the urban the rural area and urban area. So this one we question. Now, you can see from this picture is surrounded by the green and red color which represent that agricultural fields and also the forest
Nuttipon Yabueng: forest area like this. And this one show you the station that we have, and we also set out our equipment
Nuttipon Yabueng: on the top of this the station, and another sign into my city which represent the city area, and you can see it's routed by the great color which represent the urban development. And also we also have the A Martin area beside here.
Nuttipon Yabueng: And this is our stations at the meteorological center in Chilma, near the Chengma airport. Here we set up the the same equipment, and we correct the samples.
Nuttipon Yabueng: And this one, this compound that we spec that we focus more. We call the polysec aromatic hydrocarbon or Ph, which are the
Nuttipon Yabueng: products from incomplete combustions. And we found some of them, some of them already. Casinos, unique group. So this one, classified by the International Agency of the research and cancel, for example, here been so epul. This one was classified group one Cascan and we, and they also have a many
Nuttipon Yabueng: compounds that have a potential for the cast cancel the
Nuttipon Yabueng: development. So that's why we try to analyze this compound, and for briefly, result that we got. This is our sample. We correct pm, 2.5 sample. So this one represents, like a heavy Pm, 2.5, and this one like normal situations. And for the urban area and also rural area, we can see the same trend
Nuttipon Yabueng: the the line graph represents Pm. 2.5, which correlates with the bar graph which represent Pia ish for both urban area and rural area, and surprisingly, more than 70%
Nuttipon Yabueng: was accounted for the carcinogenic ph for both sides. So that's why we quite intuitive on on this, quite
Nuttipon Yabueng: on based on help risk assessment from the Ph concentration it just we. We can come up with the this result by calculation, so we can see the Pm. 2.5 here and we found, like Ph. Was higher in the rural area around 2 times higher than the urban area, right? And then we cross. And then, after
Nuttipon Yabueng: we calculate, we can identify like in the rural area, have a higher
Nuttipon Yabueng: while in the urban area we can classify as the medium rates.
Nuttipon Yabueng: Yeah, it is the result from the ph concentration only. But moreover, we also have a collaborate with the Department of Business Control Ministry of public health. We can get the data from the hospital admissions.
Nuttipon Yabueng: And this graph will show you the number of important with the Copd and asthma this disease already focus disease, for in Thailand as well, and this graph will show the bar graph. We have 2 colors.
Nuttipon Yabueng: The blue one represents male and the ping one represent female. You can see the the peak of the number of the Inpartians here every year like this, which
Nuttipon Yabueng: the same Tre, which is the same trend with the Pm. 2.5 concentrations in the light graph here every year around January, February, February, and march around here every single year. So this one is quite interesting. So that's why we tried to find a correlation between our number of importance and Pm. 2.5 concentrations.
Nuttipon Yabueng: We we can see the medium correlation for both male and female around 0 point 5
Nuttipon Yabueng: here
Nuttipon Yabueng: and when we try to analyze our data, I mean the toxic compile. Ph
Nuttipon Yabueng: pm. 2.5 and hospital admissions. We can see the train actually. So E, even we have the list data of the toxic compile, but we still can see the train around here. If the high high of Pm. 2.5 and also high, of the PH. Will fall around here. We can see the total
Nuttipon Yabueng: in party, and also high as well around this this time
Nuttipon Yabueng: this one for the urban chain line and for the rural chimney at Ching Down. We also have the data from the hospital admission at Ching down hospital as well, but unlikely we don't have pm, 2.5 data like that real time. Pm, 2.5 data at that area. But anyway, we
Nuttipon Yabueng: can see the trend. And if you look at the highlight here, the yellow highlight I can. I will highlight a trend like we can felt
Nuttipon Yabueng: Peak a peak around here
Nuttipon Yabueng: during dry seasons. Every year like this, that so the number as depends on each year. But we can see the same peak in the same period of time by the respiratory diseases in the rural area of.
Nuttipon Yabueng: And yeah, the same, we can file like so for this one is not really clear that much. So we can file their high peaks of the total importion here and
Nuttipon Yabueng: carcinogenic, ph or the the toxic compile also high. But around this time we still. In in the process of discussion here.
Nuttipon Yabueng: right?
Nuttipon Yabueng: And for the nearly last presentation I just found I just got the information from the Public health, administrative health that provide approach to prevent and address the health issue related to the air pollution that mean they also concerned about this.
Somporn Chantara: Seems like the Internet is broken.
Ryan Chartier: Yeah, I think. Think she froze.
Nuttipon Yabueng: The risk group, like the student can see individuals and elder with the some disease. Yeah, so this one is a po policy that they provide, which related to the the levels of the Pm. 2 pi. 5. For example, if the Daily Pm 2 pi. 5, less than I was
Nuttipon Yabueng: national accuracy standards are at 37.5 microcore keeping meter. They will launch this policy just promoted to re reductions of the applicants through the effective
Nuttipon Yabueng: communication once, if the Pm. 2 pi. 5 higher than 250 microgram per cubic meter, therefore that's more on the proactive operations, maybe enhance the management efficiency. Lots of things around that. Yeah.
Nuttipon Yabueng: And I think this is all for my presentation. Thank you for your
Nuttipon Yabueng: attentions.
Nuttipon Yabueng: So if you have any questions or anything to share. Please let me know.
Ryan Chartier: Very interesting. Thank you.
Ryan Chartier: yeah. Your incremental lifetime cancer risk numbers are quite high for ambient air.
Nuttipon Yabueng: Yeah.
Ryan Chartier: They they can. They can get a lot higher for for indoor and personal exposures. But for an event that's quite high, and it's probably
Ryan Chartier: underestimating the actual cancer risk, because there's quite a few additional pahs that are carcinogenic that weren't on your list.
Ryan Chartier: And then on top of that you have to consider the dermal and ingest and exposure to a particular matter, landing on skin and dust and getting in getting in food.
Ryan Chartier: so it's
Ryan Chartier: quite high. Unfortunately. Do you have any hypotheses for?
Ryan Chartier: Why, it's higher in the rural areas. Is it just proximity to where the burning occurs? Or is there a cook stove component that might plan to that?
Ryan Chartier: any thoughts? And along those lines.
Nuttipon Yabueng: Oh, yes, if you look at our area is here. And my opinion, I I think, in the Ros area here is located near the the area that can have the open burning. So that's why it's more near sort. So the that's may influence on the concentrations of
Nuttipon Yabueng: Pm. 2.5, and also the chemical composition. So that's why, during the smoke hits seasons or during the dry season, we can file high concentration supportants in the rural area more than urban area. But in we, we can file like another another work. We can file like during non smokers period
Nuttipon Yabueng: in the urban area in the urban area, also get higher
Nuttipon Yabueng: pollutants than the rural area.
Ryan Chartier: And are you looking at any other, doing any other compositional analyses of the Pm. To look at at metals, or anything like that cause. I I do have a feeling that oxidative potential is may end up being a more useful metric than just. Pm, mass going forward.
Ryan Chartier: So I'm curious if you've looked at metals because th those are gonna increase the oxidative potential of the Pm. And then I I think Matthew has a question.
Nuttipon Yabueng: Yes.
Matthew Perkins UN ESCAP: Okay, sure, thanks very much. Couple of things I wanted to check in with you with. We had also done an evaluation of the health data from the the Ministry, and there were a couple of findings that I I was hoping to get your views on. One of those was that, particularly when
Matthew Perkins UN ESCAP: viewing
Matthew Perkins UN ESCAP: acute effects, you know what admissions are we seeing in close association with a spike? Our results were very
Matthew Perkins UN ESCAP: Chris.
Nuttipon Yabueng: Sorry. Sorry, Matthew, can you please ask me again? I think my Internet it's not very well.
Matthew Perkins UN ESCAP: Okay. Sure.
Nuttipon Yabueng: Yeah. Yes.
Matthew Perkins UN ESCAP: I wanted to ask about the difference between acute conditions and time lagged impacts. One of the things that we had seen was particularly when looking at birth. Defects of children born to mothers who were pregnant during the peak burning season were significantly higher, particularly around nervous system. Birth defects and negative health impacts from intra uterine hypoxia, low oxygen in the womb
Matthew Perkins UN ESCAP: which we felt was a very important gender component, but also a key health impact of the peak season that is not necessarily captured. If we're focusing specifically on the acute conditions.
Matthew Perkins UN ESCAP: So I'd like to check if if your research has shown similar findings, or, if you believe that is not the case, city, any views you might have on on that one also, with the the urban rural exposure for Northern Thailand, we found that there was a significant impact for occupational exposure.
Matthew Perkins UN ESCAP: The pause, probabilities of people who work in directly in the agricultural sector, for example, at much higher exposure than people who would work, for example, in the city, in the hospitality sector, for obvious reasons. And we found this to be a very important component in the data model. So if you had any thoughts on those 2 points.
Matthew Perkins UN ESCAP: I'd also love to just talk to you for about a day and a half about this stuff. It's really important, but I'll leave it to those 2 for now. Thank you.
Nuttipon Yabueng: Okay, thank you.
Nuttipon Yabueng: So actually, as I
Nuttipon Yabueng: as I understand, for your pride for the women that have a pregnancy.
Nuttipon Yabueng: of course. Pm, 2.5. Pollution. Let's say applicants can have the impacts on on the baby inside as well in terms of the the developments, and also what they do with as well. And for another point. Sorry I cannot capture the that one.
Matthew Perkins UN ESCAP: This is on the importance of occupational exposure in modeling the health impacts in urban and rural areas.
Nuttipon Yabueng: Sure. Sure. In in my experience where the people who work outside also have the the higher than the the prepaid or break, I mean inside or indoor. I mean, if office, because they may have the the with the chance to expose with the Pm. To Wi-fi, or the chance that exposed to the the app
Nuttipon Yabueng: outside more than the people that work in the indoor. Yet I think it is the the interesting point that we can discuss further. So so right now, I would say, this one, I just start to
Nuttipon Yabueng: analyze the data. And we also have plan to analyze in more detail is not only the politen, and we also, would like to expand, to to analyze the methodological
Nuttipon Yabueng: parameters that can impact on this kind of disease, especially in the dry season, which is the the summer in in Thailand. So we can file their
Nuttipon Yabueng: different between minimum and maximum pen temperature have some correlate with the in part in numbers as well. So this might be another factors that we can discuss in further.
Ryan Chartier: Great. Thank you. Feel sounds like we have a few things to follow up on it after the meeting. Surprisingly, we're within 5 min of our target time. So we have a a scheduled 5 min break if folks wanna just step away for a couple of minutes and then we'll come back, and we'll start on the presentations from Vietnam.
Ryan Chartier: Great.
Hung NGO Vietnam: Yeah, Ryan, how how can I say on my slide? I need to send to the organizer, or I can say from my on my screen.
Ryan Chartier: Yeah, you.
Somporn Chantara: By yourself. Yes.
Hung NGO Vietnam: Yeah, yeah, thank you. Yeah.
Hung NGO Vietnam: Boom.
Ryan Chartier: Okay, let's let's meet back in 5 min.
Hung NGO Vietnam: 100 people and
Hung NGO Vietnam: Shampond, can you see my screen.
Nuttipon Yabueng: Yes, we can see.
Hung NGO Vietnam: Okay.
Hung NGO Vietnam: 5, members.
Ryan Chartier: Hong, you're showing up with my name.
Ryan Chartier: Let's keep it.
Hung NGO Vietnam: Oh, my gosh! How I how can I make that? I'm a.
Ryan Chartier: I I I think that's it's fine. It it must have been you. You clicked on the link that I use after I registered, and somehow it.
Hung NGO Vietnam: The.
Ryan Chartier: My name. That's funny. I haven't seen that happen before.
Hung NGO Vietnam: I try to to ching your name. Okay.
Ryan Chartier: Sure.
Hung NGO Vietnam: Yes, let's go.
Hung NGO Vietnam: but.
Ryan Chartier: Let's wait one. Let's wait. One more minute minute, Hong. Just so. It's a full 5 min.
Hung NGO Vietnam: Yeah, yeah, it's fine.
Hung NGO Vietnam: I said. That's a thing. And after my presentation, how many make a sample of application.
Ryan Chartier: Alright! Hong! Do you wanna kick us off for the Vietnam presentations whenever you're ready.
Hung NGO Vietnam: Yes.
Hong Le: Needs
Hong Le: earth.
Ryan Chartier: I I think, on the agenda Hong. You are scheduled to go first, but it looks like Hong has his presentation already up. Is that okay?
Hung NGO Vietnam: I.
Ryan Chartier: You were g.
Hung NGO Vietnam: I spoke to Hong already, and I will make it first.
Ryan Chartier: Got it yet.
Hung NGO Vietnam: Okay. Can you hear me now?
Hung NGO Vietnam: Yep.
Hung NGO Vietnam: okay, that's good. And
Hung NGO Vietnam: can you see the slides up? Move?
Hung NGO Vietnam: Let me.
Ryan Chartier: Yeah, I I can see your mouse is, is that what you're.
Hung NGO Vietnam: Yeah.
Hung NGO Vietnam: So the slide run.
Hung NGO Vietnam: I'll get Suba, yeah.
Hung NGO Vietnam: I'm ready.
Hung NGO Vietnam: So we will find another chance to visit Jamai for another workshop on the original. Huh! I will need to go, and I can pay for myself.
Somporn Chantara: Sure you are welcome.
Ryan Chartier: Alright hung whenever you're ready, I think.
Hung NGO Vietnam: Yeah, yeah. So we should start. So thank you very much. Ryan, and Rdi and other colleague us, that I have a chance to discuss today with the final result of the prospect up air quality management. By using the local sensor in in Southeast Asia, we we have been together for 3 already.
Hung NGO Vietnam: And yes, today I I just present a quick perspective of the the equality management, and Indian in Hanoi Vietnam, and also the potential application upload cost center. And after my after my presentation, how we present how it can apply for how analyzes at example.
Hung NGO Vietnam: So my presentation just have the current status of equality in Hanoi
Hung NGO Vietnam: the local sensor that we have been doing together, and the application of a local sensor in in Hanoi.
Hung NGO Vietnam: So yeah, at you already. Notice, that's the current. So that statement of air quality and I know it quite bad, we one of the worst city for the air quality like.
Hung NGO Vietnam: And yeah, you can see here some
Hung NGO Vietnam: some parameter of the the equality in
Hung NGO Vietnam: in Vietnam and in Hanoi.
Hung NGO Vietnam: For the recent year.
Hung NGO Vietnam: And yeah, on more of the indict is over the quality.
Hung NGO Vietnam: and as a main bulletin is pm, to
Hung NGO Vietnam: 10, and BM, 2.5.
Hung NGO Vietnam: And yeah, it reach over the what health organization
Hung NGO Vietnam: standard to go
Hung NGO Vietnam: by by brick
Hung NGO Vietnam: and
Hung NGO Vietnam: yeah, yes, it obviously that the air quality in in handow it it it very big challenges.
Hung NGO Vietnam: And we have running some modeling to, so that
Hung NGO Vietnam: as a air pollution, particularly in Pm. 2.5 is almost all over the city.
Hung NGO Vietnam: And yes, you can see the picture here
Hung NGO Vietnam: that can solve the the equality in in Hanoi we we need to do
Hung NGO Vietnam: more. How to keep the the air quality in. In. I know, in the region. The qualities compared to standard. And yeah, it's been a lot of team to to to do for that.
Hung NGO Vietnam: And
Hung NGO Vietnam: yes, you can see here that
Hung NGO Vietnam: the percentage of the Daily Record at the Ufm. Msc. In Indiano.
Hung NGO Vietnam: The they
Hung NGO Vietnam: is bad according to the Equality index. Quite a lot.
Hung NGO Vietnam: And
Hung NGO Vietnam: we can see here that we need to improve the monitoring either, and the modelling and the air quality management.
Hung NGO Vietnam: Well, we, we we need to to to to work on that
Hung NGO Vietnam: for the the better equality environment in in Hanoi.
Hung NGO Vietnam: and after the preferred 3 year we have been using the desk voice, sensor
Hung NGO Vietnam: in in in Hanoi and Byzant for all over the country.
Hung NGO Vietnam: and
Hung NGO Vietnam: we have
Hung NGO Vietnam: to collect the data and calibrate and compare it as a standard monitoring station in Indian in Hanoi.
Hung NGO Vietnam: and we can see here clearly that the local sensor have a good advantage because it
Hung NGO Vietnam: affordable and cheap.
Hung NGO Vietnam: and it can install easily, but it also have some little advantage
Hung NGO Vietnam: for the accuracy. And the registration standard
Hung NGO Vietnam: that, not yet upset. But the the local sensor.
Hung NGO Vietnam: So for the application upload questions, Indian Hanoi! We saw that it very much potential to to to apply.
Hung NGO Vietnam: Yeah.
Hung NGO Vietnam: you can see here that it's it's a law that the the equality management might be installed in all over the Provin Vietnam is a law.
Hung NGO Vietnam: but the the traditional standard, the monitoring station, it too expensive and the operational cost it also a lot. And sometime
Hung NGO Vietnam: with the International Funded prospect, we have some monitoring station is tone, but how to keep it on good operation and maintenance it also a big challenges on that sky. I think that the local sensor. We have a good opportunity to to apply, especially in Vietnam or as a developing country.
Hung NGO Vietnam: and you can see here that our last voice, sensor and some sensor from Thailand. Also, is toned in the in in the system, and it collected data for all over Vietnam and also other country.
Hung NGO Vietnam: And at least we have the measurement data
Hung NGO Vietnam: and how the measurement data is good. We we need to to to work on that. Maybe we can compare with the as a standard traditional
Hung NGO Vietnam: station, and they can calibrate, certify each other
Hung NGO Vietnam: in here that we can see that collaboration between the government is a region and the local community
Hung NGO Vietnam: and the advanced technology like, that's why I answer from you, that is is a key element that we can create a good equality management system in In. In Vietnam.
Hung NGO Vietnam: as a pilot project conducted by Sam, and as a colleague in Thailand Lao. We, supporting from Rt. Is very good that we can see. Obviously, that's the local sensor applicable for the monitoring system.
Hung NGO Vietnam: Yeah, once again, I in fact I I thought that one to to say that in Vietnam the local sensor is not legally allowed
Hung NGO Vietnam: to provide the the data for for for the the management system. But I think that in the coming time we we discussed with the the local authority, and then, as the other scientists that can help
Hung NGO Vietnam: for for for this, because it's only the ways that we can be user, the equality management
Hung NGO Vietnam: the traditional. It's too expensive in in Vietnam condition.
Hung NGO Vietnam: And yes. So in. In general, I think that the air quality management can use a local sensor in wire, Ranger, because it easy to install, and it's cheap and is. The maintenance it is, it is less.
Hung NGO Vietnam: And we can collaborate and integrate with it with the standard station that's up can happen as a
Hung NGO Vietnam: for the local community and the personnel use. I think that you know so very good potential that a household and a local community they can install the locust and survive themselves. And it can provide the information for forecast and real time. Prediction. So people can can can know and adapt with the the the equality.
Hung NGO Vietnam: So here is is my presentation. It's sorry. Is it? Too short? But the in in conclusion, I think that? The low question. So it's very much potential to apply in in developing country from the perspective of the technology, the management and the fiscal of of the the finance matter.
Hung NGO Vietnam: So thank you for your attention, and then
Hung NGO Vietnam: open your floor for discussion. Thank you.
Ryan Chartier: Thank you. Hong.
Ryan Chartier: Yeah, I I think before this project there were very few, if any, low cost sensors in in Vietnam, if I remember correctly. So hopefully, you can continue to make use of the sensors. You've deployed.
Ryan Chartier: probably
Ryan Chartier: not going to be good enough for any kind of policy decisions. But it. There's at least data available to, you know, researchers in the public data readily available from the low cost sensors.
Ryan Chartier: looking at some of the the fire maps we saw previously. It looked like at least in Northern Vietnam, you know. Open burning wasn't
Ryan Chartier: is.
Ryan Chartier: you know, concentrated in Vietnam as it is in some of the other countries. Are there other sources, maybe specific to Hanoi that could be targeted for, you know.
Ryan Chartier: emissions, mitigations, traffic, or or something similar
Ryan Chartier: that's not related to the the agricultural burning.
Ryan Chartier: Or do you see a lot of agricultural burning? Pm.
Ryan Chartier: Coming from other countries into northern Vietnam?
Hung NGO Vietnam: Yes, thank you, Ryan, you you're right that we have a big problem with the open burning.
Hung NGO Vietnam: And in Hanoi Sam, also, conducting a prosec on the open burning. and I think that the as a local sensor can apply to to measure Sakai of data, because as a why, we only have the the the modeling since the simulation analyzes. So if we can have some measurement timely measurement, it is very much better.
Ryan Chartier: So it sounds like in in contrast to what Matthew had said for for Thailand, where you know the
Ryan Chartier: moving forward, it's more of the deep science, understanding the the Pm. And maybe some of the some of the biological mechanisms by which it affects health. It sounds like in in Vietnam there is a need for these low cost sensors to supplement the the sparse government monitors that are available.
Ryan Chartier: so it
Ryan Chartier: hopefully, hopefully, this will continue to be useful for you and your colleagues. Hong. Well.
Hung NGO Vietnam: From the commitment.
Hung NGO Vietnam: yes, from the commitment of a Vietnam team at Cm. We trying to keep the the the the sensor for one year more.
Hung NGO Vietnam: And let's see if we can use that sensor for another. Another research activity.
Hung NGO Vietnam: Yeah. But the it have been 3 already. And I I really don't know the stable of the sensor for the long time.
Hung NGO Vietnam: but if we can use it in some somehow, somehow, we we will keep it, and we thank you very much for the project, for Rti having supported the on the local sensor deployment in in Vietnam.
Hung NGO Vietnam: It's only the first initiative activity, but it will pick the significant milestone that we can open together in in the coming time.
Ryan Chartier: Thank you, hung, and it sounds like there may be some offline conversations amongst folks. How how to keep some of these sensors up and running for the long term.
Ryan Chartier: I don't know if there's purple air data or dust boy data showing you know how baseline might drift over time compared to a reference, but at some point, if you ever do have another big effort in Vietnam, it would probably be good to try to co-locate them with a reference prior to deploying them.
Ryan Chartier: But happy to discuss that more with you if that comes up.
Hung NGO Vietnam: Yes, thank you.
Ryan Chartier: Do we have any other questions for for Hong right now?
Ryan Chartier: Nope, okay.
Ryan Chartier: let's ready for the next Vietnam presentation hong. Are are you ready?
Ryan Chartier: great.
Hong Le: Yeah, I will share my screen.
Hong Le: Okay, can you see my screen?
Hong Le: Okay.
Hong Le: yep.
Hong Le: Move.
Hong Le: Yes.
Hong Le: Hello, everyone. Thank you. Dr. Ryan. Dr. Whom give me a chain to present my study result. So I'm Dr. Hongli from University of Queensland.
Hong Le: I'm original nation from Vietnam, and also I work as a consultant for University of Medical and Pharmacy in hot immunity in Vietnam. So I today I will present that our Richard
Hong Le: and and the title is using local sensor.
Hong Le: To. Sorry. I just tried to hide the street. Okay, are you using local sensor to measure individual air pollution exposure
Hong Le: and our project name is avoid truck to
Hong Le: avoid trap traffic, related air pollution. And we use a multi-sector collaboration between health education and environment to minimize the impact of trap, a traffic related air pollution on children in Hot City, Vietnam.
Hong Le: and our project funded by United States Agency International Development Usid under Laser Pune program, and we collaborate with Department of Education Training Department of Health, and for in city we have support also from DNA. Call up a card company in Vietnam. This is a startup about local sensor
Hong Le: device. We also have the participant over 1,000 children and their parent and our reset team member include a receptor from University of Medicine and Pharmacy in hockey, and also University of Queensland, Australia.
Hong Le: And, as you know, air pollution is a global concern, and in which Pm. 2 profile is one of the most important pollution. In fact, our human health.
Hong Le: and, according to war, air quality report, in 2,022 Vietnam ranked the third among the most polluted countries in Southeast Asia, with an average, a new Pm. To provide concentration as it's
Hong Le: I sit in 5.4 times.
Hong Le: That is Friday, in the new guideline of the pledge, or in 2,021,
Hong Le: and in our study we we can find that Pm. To when the children children is up for notable population to the air pollution. So the children spend over 30% of their time as soon and during the time and the time to go to school, and they expose to trap evolution traffic rate, air pollution in from human activity, from the
Hong Le: broad vehicle, admission, construction, industrial emission, and when the when the children spoke to air pollutant, they can give some possible mechanism for assemble skin bearer, dysfunction, oxidative damage or inflammation, dysfunction.
Hong Le: and this helped. This a health mechanism. We encose the respiratory symptom for a simple reason, etc, are also respir resp respiratory, respiratory disease for assemble, asthma, allergic corinitis, asthma, acceler, respiratory infection.
Hong Le: So in our study we want to answer 2 questions. The first one, what is the current data on the air quality at school by BM. 2, 4, 5, concentration.
Hong Le: And the second question we want to answer, what is respiratory health problem in the population of school children, and is difference by social, demographic, and school related condition.
Hong Le: So this, the next part is our methodology.
Hong Le: We have for school participate in our study to spoon in, in residential, in their in residential zone we convin district, and we have to spoon from Bintend district. This is the this school, close to Big road and industrial zone. So we conduct their study from August to December. We followed. We
Hong Le: we foreload the data from August to the December. During that we we conduct this survey about respiratory symptom. We we to the student, the student from 4 school break from 4 to 7, and about the same site totally
Hong Le: 1,000 school children in for school. So during the hours during our study. We also conduct a many respiratory health examination Len function, Len function and urine test
Hong Le: but we don't have time today. So I I I will not present many. How dates are today.
Hong Le: Regarding to how I do measure air pollution. We we also measure outdoor and indoor environment and also individual exposure with air pollution for outdoor and indo environment. You can see on the picture the picture we've used
Hong Le: for palm am monitor. We we put on outside the school and locate it from 3.4 to 4 point meter up, hold around level. In each school and in class we have trail palm, a monitor in inside classes, and we measure Pm. To both 5 and it will give us the Pm. To qualify means every hour
Hong Le: individual exposure in regarding to individual exposure. We also use the combination of Ap. 3 from Habitat Company and micro pan from Rti Company to measure personal air pollution, exposure. So the the Chi you can see on the picture. They will war, they will, they will! They will wear the device in front of their bodies.
Hong Le: And we have trail microb children and 64 apim children. Have a data.
Hung NGO Vietnam: Monday, and.
Hong Le: And we we for this for 13 children who who we wear, who wear, who wore the AV tree and micropen at the same time, and we put on the the small back, and they went 48 h.
Hong Le: And this is our result.
Hong Le: The figure one short, the distribution of daily 24 h mean Pm. To qualify concentration.
Hong Le: and we can see the different significant different between 2 to groups. Does the school from the school close to big rot and industrial zone, or and the school in residence or zone.
Hong Le: and we can see in the right in the right season that. Pm, 2.5 us are higher than the rainy season and 24 h average mean. Pm, 2.5 meetings over 51 in.
Hong Le: In in school, close to the big row and industrial zone for the school in residential zone, the PM. 2.5 mean around 34.0,
Hong Le: and we can see in the for in the drop.
Hung NGO Vietnam: What is it?
Hong Le: The elevated level of Pm. To go for us in in November and December in the right session. But the the pattern are similar into in fall school.
Hong Le: and next the figure to show the distribution of our Pm. To provide concentration over 24 h.
Hong Le: and we can see the Pm. To qualify Hi
Hong Le: during the night, hum in the in the scoon cloth to thick throat, and industry also on, but less than in error, with a rest in a schoon in a residential zone.
Hong Le: and we can see the during about 4 Pm. The PM. To 4, 5, 10 to ingrade until nighttime.
Hong Le: So that's either time where the children go back home. They they they go to. They go back home or travel to the school, travel to harm or travel, and they usually go with their parent, or they have some extra class after the official school day.
Hong Le: So that's why they still outside. But for some activity, and Pm. 2 provide PPM. 2.5, still high.
Hong Le: and the figure 3 will show the correlation correlation between Pm. 2, profile concentration record by Apm. 3. And micro Pam unit. We have. As I told you, we have a 13 children where the same app, and my Ab and my Pam, and we have, we have a 13 parent unit
Hong Le: and the wrap. Rob. I will show the Pm. 2 profile concentration record by micropam less than 600 micro RAM from cubic meter and be crap.
Hong Le: We will show you the Pm. To both 5 concentration record by micropm and a Pm. 3, less than 200 micro ramp cubic meter.
Hong Le: And we can see
Hong Le: the data request
Hong Le: quite interesting when we use the spammer correlation test, and we found a Pm. To provide concentration monitored by abim and micropam, show a significant, strong, strong, strong correlation with our equal here 0 point 7, 4,
Hong Le: and the figure 4 show us a Pm. To qualify concentration with the limit. 100 micro cubic meter exposure by it. 30 min of the day. For on combined personal sample.
Hong Le: So we mishe, we have a total. We have total over around 70 children with Ebm. And this is the data from Ebm 3
Hong Le: you can see the Pm. To provide concentration among students very significantly within 24 h, and so regular chains over the time.
Hong Le: And the next figure about the next figure figure 5 is short, the mean Pm. 2 or 5. Concentrations with standard error by micro environment or activity. For on come by personal sample. So in our study we have their diary
Hong Le: collection. So children in, we children have to report their activity each 30 min.
Hong Le: and in 24 utter in 48 h. And and this is the the figure, if I show us them
Hong Le: the each activity and the Pm. To provide concentration for each activity, and we can say the highest.
Hong Le: Here is our second hand smoking. Sorry burning is saying secondhand, smoking, cooking at home, and most up at the top 3 is from indoor air pollution. Is it right? So we can say every particular concentration will highest. Why the participant were experiencing, followed by second hand smoke and cooking smoke.
Hong Le: and the next figure we show you the wheezing of Ranitis in the last 12 months.
Hong Le: and
Hong Le: the first is from the school, close to Big Row and Industrial, and the second from the school in residential zone, we we found some difference between 2 school groups. However.
Hong Le: there is no evidence between between 2 groups.
Hong Le: and oh.
Hong Le: we also, and the next. The next.
Hong Le: A resolve
Hong Le: is show you the reference of wheezing and grinitis. These are some key respiratory symptom in the last 12 months by school related to related condition. And here we can say the significant.
Hong Le: Oh, sorry! We can see the significant difference between the children spend less than 15 min on the road, or over 15 min on the road. So that's mean the children who spend over 15 min in the road every spoon day, and we have more prevalent, have a higher prevalence of symptom.
Hong Le: So that is our conclusion. The we have the first one we can see. We can see the concentration of Pm. 2. Profile at scoon in residence or area.
Hong Le: It's about the means. The the means is 31, and as soon close into big pro with an industrial area, or with the mean in with the means, is 61.2 micro 5 cubic meter. So on, I see the Wso standard.
Hong Le: The second conclusion we can found the reference of respiratory symptom was higher than reported in early study in the last decade.
Hong Le: but the revelers of bre respiratory symptom were not significantly different. Between 2 screen roof
Hong Le: and the Pm. 2.5 concentration among students very significant
Hong Le: significantly within 24 h, and rich high when the participant is both indoor air pollution. For example, you can see in our study, insane from it, burning sand, burning incense, some secondhand smoke and cooking smoke.
Hong Le: and the prevalence of wheezing was higher among school children spend over 15 min in road travels from school. So from our study we found that the children, not just exposure to traffic air pollution, but also have a high risk at the high risk of indoor air pollution.
Hong Le: Okay, so that is all my presentation. Thank you for your listening.
Hong Le: If you have any question, feel free to add me now.
Ryan Chartier: Thank you very much
Ryan Chartier: similar to to what Matt Matthew said earlier I I could talk for hours on personal exposure.
Ryan Chartier: I think we've worked together on projects.
Ryan Chartier: I do. You have any issues with recall bias for the time, activity, diaries, particularly with the children. I know that is
Ryan Chartier: often a concern, especially when there's no co-located GPS data to actually track where they are. Was that an issue in your study?
Hong Le: Yeah.
Hong Le: Hmm, yeah, thank you for your question, mark. That's a good idea. We
Hong Le: we, I think that's a one function from error. Micropam error. Ti, I'm not sure 100%. But Ryan can can tell more about that. But I we didn't do that. The reason is because the ethic.
Hong Le: So you know, when we conduct a study in children in Vietnamese children, we have to pass for many states of ethic
Hong Le: process. So it's we cannot do if we do the GPS. Anyway, I think we we didn't do that. But micro pam, I think it can do it.
Hong Le: Yeah.
Ryan Chartier: Yes, we
Ryan Chartier: Irv approval for working with children. I'll just always
Ryan Chartier: tedious for sure.
Ryan Chartier: I we recently did a study
Ryan Chartier: similar to this with asthmatic children in the United States.
Ryan Chartier: and we found that they're ultra fine particle exposure so particles. Less than 100 nanometers in diameter is elevated during transit time. So when they're traveling in a vehicle. So I I'm I'm not surprised that you had more instances of of wheezing. In that case. Different kinds of particulate matter likely have different kinds of
Ryan Chartier: amount of toxicity associated with them with
Ryan Chartier: emissions from vehicles being.
Ryan Chartier: you know, high end metals
Ryan Chartier: cause a lot more oxidative stress and lead lead lead to wheezing and inflammation.
Ryan Chartier: also, in the comparison between the
Ryan Chartier: the microp and the airbeam. 3
Ryan Chartier: just so everyone knows I I designed the micro pump in the children's version. So I'm intimately familiar with it and how it works it. It applies a relative humidity correction factor in real time.
Ryan Chartier: And I don't think the Airbnb 3 does. So
Ryan Chartier: I'm wondering if some of the deviations could actually be minimized.
Ryan Chartier: If you account for the relative humidity across the measurements?
Ryan Chartier: Just you have a strong correlation. Anyways, I'm just wondering how how that would change if you account for humidity something to look at. No, no real question. There.
Hong Le: Yep. Yeah, that's Yeah. This is a the Tessa initial analysis
Hong Le: from our team. I, as as you can show, as you can see in my presentation. We also have a urine test and learn function test date for lunch function data. So we would. We will try to combine many different part data part together to to answer the question. Yeah, but we didn't. We haven't finished data, analyze it. But that's a good recommendation I would take. Not in a way of it. Yeah.
Hong Le: thank you must.
Ryan Chartier: Lot, lots of good data. H. Hung, you have your hand up. Do you have a question.
Hong Le: You!
Hong Le: Yes.
Hung NGO Vietnam: Yeah, yes, I'm here. Yeah, yeah, it's not a call question. It's a easy. It's a comment. Yeah, so thank you very much. Yeah. Your presentation just to make my my. My presentation is more clear. I'm sorry that in the abundant time I I don't have many time to to prepare and talk, but obviously, that everything that need
Hung NGO Vietnam: to be apply is a local sensor in in, in, in the developing country.
Hung NGO Vietnam: Yeah, for the children, I think it's very crucial and and it applicable. I'm now working for
Hung NGO Vietnam: one reason that the organization working for for the the children the next generation. So, Ryan, I'm thinking that we can create something new with the Dos. Us
Hung NGO Vietnam: that can support it and home lake and lead on that. I'm I'm in with a follower.
Hung NGO Vietnam: so on the sensor. We can really relocate it up as a project. With this and homeland you can decide it on that. And it started Ryan in in Rti. So how? How we can handle the situation and we can best you. But my my curious question is, how long it can be used, because it had been used in 3 year.
Hung NGO Vietnam: And can we use this for the next 3 year? For example.
Ryan Chartier: I think that's unknown. At this point. Hong. The folks at Purple air may have more information on how the optic soil over time. But I think if you co-locate the low cost sensors with a reference device or even a research grade device, confirm that they're working correctly, then it should be okay to to use them.
Ryan Chartier: and and we can. We can talk offline. But it no, I I agree there's lots of space for collaboration, and if if the studies health focused Nih or something similar, maybe a better target. But
Hung NGO Vietnam: I I would love to do that. And with a new affiliation, I still keep in touch with the University for the Academic advisor as a as a free, free. Yeah, Jack, I do. We follow up for the remaining student for
Hung NGO Vietnam: overseas study.
Hung NGO Vietnam: and I willing to to, to, to to discuss, and then let's see if we can find some interesting to do together last month. I also may have a meeting with the Us. Embassy in in Hanoi, and I saw that they develop a portfolio of the investment in the coming time. I'm not yet keep up. Let that with the
Hung NGO Vietnam: with a colleague out there, but I think that we have a good chance for the not only Vietnam, but for Southeast Asia also.
Hung NGO Vietnam: So I hope that after this meeting. Ryan. Still keep in touch with that and letting the team go together.
Hung NGO Vietnam: And I'm I'm really looking forward to meeting Chung line because we have a date of that, but we
Hung NGO Vietnam: we're not able to to make it.
Ryan Chartier: Yes, we'll certainly keep in touch. Matthew, you have your hand up. Do you have a question.
Matthew Perkins UN ESCAP: Yeah, I just wanted to come in briefly on this. And really praise this work. I think this does a great job of advancing the science on a number of really policy relevant issues. And I'm really excited to know more about it.
Matthew Perkins UN ESCAP: Including. I don't know if it's suitable for this call. But I I'd love to have a conversation about replicating this work in other cities, and and what that would look like from a a budgetary and and process perspective. You know, I think this is has really triangulated why, it's so important to have more insight into the household exposure
Matthew Perkins UN ESCAP: and personal exposure, dimensions of of air, pollution, and and public health. So just bravo! To all involved, and hope to take this forward. Thank you.
Hong Le: Thank you. Ma.
Hong Le: thank you. Ryan and Dr. Hall, I just have a last comment. Not just only this project, but also, we also have another project, and we also measure the traffic traffic evolution exposure and no traffic is polar during the COVID-19. And we found that the children have a very. We have a high risk of indoor air pollution. So I think low cost
Hong Le: really have to measure individual exposure. So we can think about that. Yeah.
Hong Le: yeah, thank you for your comments.
Hong Le: And I'm happy to collaborate my email here. And in the in the group chat very happy.
Hung NGO Vietnam: Out to 5. Extra. No worry. Yeah. Yeah. And in in in what vision? No, we also develop a a portfolio for the urban area, and also because we forgot on the children. So I I think that we will keep in touch and discuss further.
Hung NGO Vietnam: Yep.
Ryan Chartier: Sounds good and without personal level measurements. It's it's sometimes difficult to get at some of the mechanisms of what's causing the health effects.
Ryan Chartier: It's it's more difficult on a population level. So
Ryan Chartier: yeah, a big advocate for those direct personal measurements. Although they are costly and logistically complicated, they can provide very high quality data. So
Ryan Chartier: alright, Keo, you're our last
Ryan Chartier: presentation.
Ryan Chartier: do you want to? Are are you prepared.
Keophousone Phonhalath: Yes, thank you, Ryan. Yes, I would like to share my screen.
Keophousone Phonhalath: O
Keophousone Phonhalath: poop!
Keophousone Phonhalath: Can you see my screen? I mean
Keophousone Phonhalath: my strife?
Keophousone Phonhalath: Yep.
Ryan Chartier: Can see.
Keophousone Phonhalath: Great. Thank you. Thank you, Ryan, and everyone. My name is Gail, who's on from Hala. I'm working at the Faculty of Interior Departmental engineering. And I'm the one as the Ryan. It was mentioned before. I'm the
Keophousone Phonhalath: one of the team, and as the next known team
Keophousone Phonhalath: actually, we are many, many people that include in the team. But this paper that I would like to show for this workshop is we work together that 3 advisor. And this topic, the student is was the one we're the one that done this topic.
Keophousone Phonhalath: Yeah, under the our project. So this one, the topic is evaluation of PM. To qualify at
Keophousone Phonhalath: 9 village in Ventan. Capital log. Pdf.
Keophousone Phonhalath: this one. So the this one is the content. I would like to talk about. So first, one introduction methodology. There is our Pm. To qualify for the er version and conclusion.
Keophousone Phonhalath: and the first one about the introduction.
Keophousone Phonhalath: Actually, Laos Vietnam.
Keophousone Phonhalath: we have the same situation, especially Laos and Thailand, at the northern part of Laos. Actually, we have, we got these situations in long time as the activity of the the agriculture. One thing is, they did they do slack and burn at the northern part in Laos, not just early on in the northern part.
Keophousone Phonhalath: See is from northern part until southern part.
Keophousone Phonhalath: especially on high hill or mountain, on a mountain, that they do slap and burn.
Keophousone Phonhalath: and some activity that can produce more pollution in la is one is the that now is transportation allows one house they will have, especially in winter, and they will have about
Keophousone Phonhalath: 2 or 3 car in one house, so this one that everyone
Keophousone Phonhalath: go out and reproduce the pollution. Actually the government. They have the the, the law for controlling the how to say release the emotion or control the emotion relation. So this one is so, the the technical. They always try to fix the car to make, not to make the car got problem, but still still some truck or some car that they still produce the pollution in the air.
Keophousone Phonhalath: and the other side you can see the picture on the right side. At the top you can see that landfill is not sanitation landfill, and it's just landfill that they done the waist and yeah, the down the waist. 1 one way to put reduce of the waist. They burn the waist.
Keophousone Phonhalath: some some place, and some also that we not yet got the information. They also burn also, because they want to reduce the with at the land. So they dumb so they dumb, and then the burn. So that's why that some some sauce is can be from the landfill. That is not sanitation landfill in the lock, in house. So this the problem in louse longer, and the other one also. We
Keophousone Phonhalath: they are now, the industry will increasing so many, many, the the economic zone in Laos, in especially in venture and capital, there are many economic zone, so this one can produce the equality emission outside. So this one can produce da da
Keophousone Phonhalath: problem
Keophousone Phonhalath: before this topic in last year. Actually, we done about delays this before before this topic. In 2,002 at that time that we could install only full point. So that tell me, we monitoring
Keophousone Phonhalath: at the online data
Keophousone Phonhalath: for 4 point. And after that we focus on this location is venture capital ethnic story.
Keophousone Phonhalath: Actually, in Vinton capital there are 9. There are 9 district, but we study only for district, because the installation at that time is was not full, so we study only for district, for venture capital at that time. So for the first one we study at the Sequo district there are 2 point
Keophousone Phonhalath: for sensor installation. The sensor installation is purple air is as the hung present. Before that we use purple air is the low cost. And thank you. This project give us to monitoring the the equality for this. Otherwise we could not get this information to to promote it. How the quality is lost. Now
Keophousone Phonhalath: the second second district is at the map. There are 2 point also in this, and the other one in has a phone. This week is nearby Thailand. This one is the only one sensor.
Keophousone Phonhalath: The other one is Sizetta Sicita. Is this, one is nearby. The
Keophousone Phonhalath: so I said, economic zone, economic zone. And so this one. So you mean that it can produce from the economic. I mean industry sector.
Keophousone Phonhalath: And yeah, the dental dental is near near by Sizetta. And it's the big one, the big area that yeah, so, and there are many people people in there in this district. So we choose, 2.1 point is nearby, really Density House. And there are many school, and there are many office around there, and the other one is near nearby the size. So it's nearby. The
Keophousone Phonhalath: economic. So
Keophousone Phonhalath: how does work does our work will work at the
Keophousone Phonhalath: 5 period. The first time we work from night January
Keophousone Phonhalath: to 13 January is for 5 days, and and the other second hand, from 6
Keophousone Phonhalath: February to 10 February, and at that time we work from 13 to 17 months.
Keophousone Phonhalath: The time is from third to 7 April
Keophousone Phonhalath: and the fifth. We were from first to 5
Keophousone Phonhalath: May in 2,023,
Keophousone Phonhalath: and every work that we work is for is
Keophousone Phonhalath: each month. We work for 3 3 days, we record the data, we collect the data from the website.
Keophousone Phonhalath: So when we collected account that that detect the equality of Pm. From 7 to 6 Pm. In evening, while we choose this time, because during this time in early morning they use the the transportation from 7 until 9, and after that they stay at the office, and they went out for lunch
Keophousone Phonhalath: about 11 to to 1230, and after that in the winter in Laos. They start working around 30,
Keophousone Phonhalath: 3, 32, 4,
Keophousone Phonhalath: and if the government of this, because they is will be transparent
Keophousone Phonhalath: traffic jam. So they went out from the office in 3 30 until 4. They start already, but some the private sector or private company. They start at 5, start fi, and stop at 6 about that. So is that that we choose the situation
Keophousone Phonhalath: and the acumen as this, we use that under the project this one is proper, and we use that and installation. This one is that the
Keophousone Phonhalath: and this one is the step of information.
Keophousone Phonhalath: So in this.
Keophousone Phonhalath: after we install, and then we collect the data, this one, we call it online data online data for 12 h. So we collect as that. I said before, the period of the work. And we collect 2 data. Actually, we call it, that is, one Pm to Wi-fi and Pm to Wi-fi Api that we have to. But today I would like to show you the data of raw Pm, to Wi-fi of this area.
Keophousone Phonhalath: This one? Yes, we call it that. So this one is the result of my village. So this one is the first village is Gangpayang. This one is by Thailand. Actually, this one is nearby. We call Mekong River and nearby Thailand is is far from from the rural area. So this one we can see. The result is really low from the
Keophousone Phonhalath: lower than the standard we use. This analyze this, we use the standard of loud. So national environment 2,017 so this one is lower than standard, because it's very far from the the
Keophousone Phonhalath: transportation far from the road, and it's far from the
Keophousone Phonhalath: how small. So we choose this one to be one example. So we can see that it's lower than the standard.
Keophousone Phonhalath: And yeah, second one is some Web village, and this one is my house. This one is this my house is nearby.
Keophousone Phonhalath: Nearby Mini school and nearby temple, nearby main road and nearby market is far from market, about 500 meter and far from my faculty, about 2 kilometer, so is I choose this one to be with one example in the district, so we can. How that is well
Keophousone Phonhalath: higher than standards in January until May, but the domain was lower, because
Keophousone Phonhalath: last year the brain was start in May
Keophousone Phonhalath: early of the May, so it mean that this one is can be reduced of the PM. 2.5 in the air.
Keophousone Phonhalath: but the other higher it was in April. You can see it's working April. The the quality or the temperature in Laos last year in April is about 40 to 44 degree. So this one is can impact to this. Apm 2.5 was increased.
Keophousone Phonhalath: But yeah, I don't. Yeah.
Keophousone Phonhalath: for the other one is what not. Village is. Our tech company is this office but this one? Why we choose this one? Because it's nearby. Edl Company, nearby Katie Sax School, nearby to Temple and nearby other technic school.
Keophousone Phonhalath: and nearby the Whatnot village is. So we choose this location
Keophousone Phonhalath: and the same situation, but different in February. So this one in the February is not different, much with much, but in April is more high, because is this
Keophousone Phonhalath: pioneer with my house about 2 kilometer? So is I. I must have
Keophousone Phonhalath: that time many transportation. They use this road nearby, our our our office. So the their main transportation, and the tempo and the people transport too many. So it's one high and no rain yet in the May, so it's what the rain start. So it the the Pm. 2, p. 5, was reduced
Keophousone Phonhalath: in tensor at midnight
Keophousone Phonhalath: points are admin less. This one in size.
Keophousone Phonhalath: Sizetta is nearby tag one temple you may hear this name Tagline Temple, that's really famous in love.
Keophousone Phonhalath: and it nearby many government office.
Keophousone Phonhalath: It's nearby. Patu site
Keophousone Phonhalath: many office nearby has so many people to that they transport around there, and many talk with them in this area.
Keophousone Phonhalath: It's the same in in April. It's one high, and it's worth 100.
Keophousone Phonhalath: But it may also was reduced the same situation with other press.
Keophousone Phonhalath: no one also nearby Ponza. This one is nearby.
Keophousone Phonhalath: Thailand Embezzi, Indonesia Embassy near by. Patosai.
Keophousone Phonhalath: nearby.
Keophousone Phonhalath: Vington College. Also, so it's what really, really traffic jam about down here, especially about 5 to 6 pm. They use car that transport to bring their children to study in Ventan College in this area. So it was
Keophousone Phonhalath: and so we found that so in April was higher than 150. As I mentioned before, that there are many transportation around there.
Keophousone Phonhalath: Yeah, in this long gone there are no factory. There are no factory logic. Once I run so no factory.
Keophousone Phonhalath: But the at my village. Just some factory only, but it's not big factory
Keophousone Phonhalath: in Nando. Nanguang is in US. And supportable.
Keophousone Phonhalath: She caught the longest one
Keophousone Phonhalath: this area. There are many factory and there are many economic. But it's not economic. So on it, just economic shop that they sell. And there are many Chinese people stay in there, and many hotel, many restaurants
Keophousone Phonhalath: in this area around there, in this around there, so that we found that even is not big factory, but we found that in April it will higher than 140. So this one the situation.
Keophousone Phonhalath: this is way. Hoi whole is nearby main compass of our National University of La, or the main campus, is located at Don. Do. This. One is very near. We don't know is for about 3 or 4 kilometer.
Keophousone Phonhalath: And in this area really density density, because there are many what we call dormitory, that or apartment or student that they're in the the room. They're in the room for study in Dodo campus.
Keophousone Phonhalath: and many, many many shop, many restaurant, many phone shop.
Keophousone Phonhalath: and many how to say that we call what we call the bar around, not not the bar near. Don't go, but the bar at the my home, that there are many bar or many restaurant that you drink. And so there. So that's why around 6 Pm. That they will start to transport or travel to the bar or travel to the restaurant around doing so that we can find April is what high. So is about nearly 200.
Keophousone Phonhalath: Me and Nico, grandpa, make make him yeah
Keophousone Phonhalath: in Batang. Batang is nearby. The South Northern Half Bus Station, Northern have a station and is nearby airport, and so
Keophousone Phonhalath: it's nearby. Many house around there, and the company, the main company of the private sector. That they, they, they, they, they are located in there. So this we can file. That is higher, was higher than 200 in April. So university
Keophousone Phonhalath: situation.
Keophousone Phonhalath: That tone that tongue is one is located at the water resource faculty.
Keophousone Phonhalath: We we asked to install in there that is nearby.
Keophousone Phonhalath: It's nearby, Pakan, but it's far from Pakina, 5 or 2 6 kilometer. This one is nearby. The car.
Keophousone Phonhalath: So room car, so room that they they sell the car around that many, many so room car in there that's located along the 13.
Keophousone Phonhalath: Not road that there are 13, no road that they transport to the north, so there are many, many people, and they use the highway, and so that the highway also nearby that home
Keophousone Phonhalath: village also, so that maybe many transportation about the factory. There are not many factory around there, and the the the activity of the shop activity of multiple shop activity of the the what we call
Keophousone Phonhalath: eva bicycle. Also add the that just located in there now, so that that many people to receive in this area. So it's worth higher than 108, 18.
Keophousone Phonhalath: So this one is the result of the vapor that I told you before, so only Kangpayang is was lower than
Keophousone Phonhalath: spend that.
Keophousone Phonhalath: But the other place that people
Keophousone Phonhalath: travel, transport and the factory nearby them. So it's worth. Produce the airport, or especially Pm. 2.5 a loop as well. Higher, we're higher than that.
Keophousone Phonhalath: So this the conclusion. So the highest, the Pm. To qualify according to our study, is most higher at the web, not our faculty, because it's nearby. Many people. And yeah, they transport to here by Motorbi and car so, and the surrounding also, they transport to the Edl office to they transport to the school they transport to Temple, so this will higher than the other place.
Keophousone Phonhalath: and for Tampa Young is what the Lower West the lower one, and for some boy whatnot phones are at Nong. They they this one that nearby, the the Mini Shop School Council, using revenue application, that nearby area.
Keophousone Phonhalath: So this at the end of my presentation, thank you for your attention and thank you for your question. Comment. Thank you.
Ryan Chartier: Thanks so much, Cale.
Ryan Chartier: I'm surprised any of the villages were below the standards at this time of year, just based on the amount of smoke that we've seen, and and
Ryan Chartier: all of the Southeast Asia area.
Ryan Chartier: reek.
Ryan Chartier: How how much
Ryan Chartier: in the other villages? How much of the Pm. Do you think is due to the smoke during hay season versus some of the more local sources?
Ryan Chartier: Is that something you you've looked into because it's hard to differentiate them. With the low cost sensors, what do you feel is is.
Ryan Chartier: you know, the input from the the smoke versus local sources, like traffic or restaurants.
Keophousone Phonhalath: I think this
Keophousone Phonhalath: the the situation of the smoke in this area there are many smoke, as you see at the picture at I saw. And at the end, Webex.
Keophousone Phonhalath: yeah, you can see this picture there. How many? Actually, I I
Keophousone Phonhalath: I I was not prepared for it. Actually, I was
Keophousone Phonhalath: in Longview I saw the situation. The same is the picture also in Longvia and the other place also. This mean the situation now of the smoke is really
Keophousone Phonhalath: is very high in this season before raining coming in May. So it and and the situation of a pollution. Actually it was passing January until
Keophousone Phonhalath: until April same last year as a the same situation. The smoke was really high during this time, and start the raining in May June, and it it will start again in October or November because it's dry season. And then actually in October and
Keophousone Phonhalath: October.
Keophousone Phonhalath: November and December is not really high, but start in January, and the the source of this are small.
Keophousone Phonhalath: In one year I found that it's from burning slack and burn, but in Vmtium is not the source from mass, from slack and burn slide. And was they active in some home district?
Keophousone Phonhalath: Santong district is nearby, and the way to to Milan. Thailand, that's what so is is they do this activity to make clear the land for agriculture before the rain come in.
Keophousone Phonhalath: But for wind tunders, the smoke there come from transportation
Keophousone Phonhalath: and transportation and the the erectic, I mean the building they use erectic. Some transport heat. It's come out, and the other one is from the factory that they produce some application, that outside that
Keophousone Phonhalath: did.
Keophousone Phonhalath: So, yeah, yeah, so is I'm I saw this, the low cost people is, can you as much in the previous time? Laos? Actually, we, the government, they have the equipment for monitoring, but is difficult. We can use this with them. They they will be monitoring by themselves.
Keophousone Phonhalath: The the national you see about cannot cannot use that. Well. So we thank you for this project, and so that he'll ask to monitoring this. And we can keep this information to the government in the future. Yeah.
Keophousone Phonhalath: yes.
Ryan Chartier: Thank you. Yep.
Keophousone Phonhalath: Yeah, how I've done.
Somporn Chantara: Yes, thank you.
Somporn Chantara: Thank you, Cal, for your presentation. So I just would like to mention. But you would say that before that, did you also co-locate your local sensor with the Government and quality monitoring station or not? Because at first we we need to to see whether our sensor. Pm. Deployations are related well with the Quality monitoring station belong to the government or not. The second part is that
Somporn Chantara: it will be more clear if you can plot the graph, using the maybe daily concentration. So we can see the fluctuation between days.
Hung NGO Vietnam: On the Delete Tomiser.
Somporn Chantara: In in in in each location. So it's will provide us more detail on that. Because I think we we have like second or hourly data.
Somporn Chantara: So it would be better if you can plot in detail. So maybe your students can do that in the future.
Somporn Chantara: Thank you.
Keophousone Phonhalath: Thank. Thank you. Attend some, Paul. Yes, yes, I also.
Keophousone Phonhalath: I agree. I do agree that I have to compare with the government sensor. I able contact to the government. We have to make clear on that. And as now they try to collect the data back
Keophousone Phonhalath: and they want to
Keophousone Phonhalath: promote, or they want to inform their data first before they keep us that information. We also want that to compare this data that we make sure that we? That's why our paper not yet public, because we we would like to come, have the the government data
Keophousone Phonhalath: at that one and the other one that you mentioned that we have to make the map of personation. Yes, we we will do that in the future. That's on the next issue.
Keophousone Phonhalath: Claudia still done. Yes, thank you.
Ryan Chartier: And I think it's also good to point out that, unlike some of the other areas where we deployed the purple airs.
Ryan Chartier: we needed to purchase Internet
Ryan Chartier: like cards or programs for for some of the locations in in Laos, just because there's no Wi-fi available.
Ryan Chartier: So that is
Ryan Chartier: that's going to be an ongoing issue in some of the more rural areas, I think in Southeast Asia. If we
Ryan Chartier: if somebody's gonna deploy more sensors is, how
Ryan Chartier: how do you
Ryan Chartier: get connect them to the the Internet? So they upload the data to the various platforms.
Ryan Chartier: and then what do you do when that Internet goes down because I believe you know, some of the deployments took multiple days of travel, correct Kao, to to
Ryan Chartier: get somebody out there to deploy the sensor and then come back was took days as opposed to, you know.
Ryan Chartier: a quick deployment like we're used to sometimes in in other projects.
Keophousone Phonhalath: Yes, thank you, Ryan. Yes, as I work, and I able report at Laos, and that is difficult. One thing is
Keophousone Phonhalath: the the Wi-fi. As you mentioned that we have to choose the location of the point that they have Wi-fi, and the other one is the the government. The local government, we have to inform them, although to inform them they want us to install at the location that they have the Wi-fi, especially at the Rental office.
Keophousone Phonhalath: So we install install at the the the local Government office, so that they can monitor all monitoring with us.
Keophousone Phonhalath: especially in Kings Ali
Keophousone Phonhalath: long hab and second, and so that they want to monitor with us. So we choose that they have the Wi-fi mean that the area that extend outside of that. They don't have Mass Wi-fi even nearby the border with Vietnam also they don't have, and they don't allow us to to to start that will. This will really challenge for us at the time.
Keophousone Phonhalath: Yes, thank you.
Keophousone Phonhalath: Go at that
Keophousone Phonhalath: great.
Ryan Chartier: Thank you
Ryan Chartier: any other questions. Yep.
Ryan Chartier: I see a hand up.
Sudjit Karuchit (SUT): Hi! My name is Ajit from University Sorana University.
Sudjit Karuchit (SUT): Thailand.
Sudjit Karuchit (SUT): I just have a question. Why didn't you
Sudjit Karuchit (SUT): make sure I'll use 24 h
Sudjit Karuchit (SUT): concentration averages.
Sudjit Karuchit (SUT): I think you use 12
Sudjit Karuchit (SUT): hour
Sudjit Karuchit (SUT): right?
Sudjit Karuchit (SUT): And when you compare the 12,
Sudjit Karuchit (SUT): our ailer rate.
Sudjit Karuchit (SUT): we've
Sudjit Karuchit (SUT): 24 h standpoint.
Sudjit Karuchit (SUT): It's not exactly
Sudjit Karuchit (SUT): comparable.
Sudjit Karuchit (SUT): I mean, you are. You're using
Sudjit Karuchit (SUT): the
Sudjit Karuchit (SUT): the high concentration period
Sudjit Karuchit (SUT): with the
Sudjit Karuchit (SUT): Ariz, with
Sudjit Karuchit (SUT): I mean the stand down which
Sudjit Karuchit (SUT): intend to
Sudjit Karuchit (SUT): to be to represent
Sudjit Karuchit (SUT): 24 h.
Keophousone Phonhalath: Yes, thank you for question. Yes,
Keophousone Phonhalath: At that time it was the initial study. At that time we discussed at our department. We just for actually, we want 24 h. But the capacity of the people that work at that time cannot work well, and the Wi-fi. So it's not, is not well at at any point. So we we just for 12 h in order to collect, because
Keophousone Phonhalath: some point they checked out the Wi-fi, I mean, they block out purple air for for us. So that's why the data we choose really difficult to get. They block out the the proper air. But the Wi-fi, I mean even the Wi-fi, not Wi-fi. They plug out the proper air, so we have to communicate with them, not to block out, but some they also follow, but some not follow.
Keophousone Phonhalath: So we choose the daytime that that that they block the purple edge a. A. As so we choose that 12. But in the future we also will plan that we want to do on the 24 h. So we have. We make plan to
Keophousone Phonhalath: communicate
Keophousone Phonhalath: with the owner of the house to let us to do that. You know, as as you see on the map, some point they block out. Even we try to connect, communicate with them that they block out so we cannot get. We could not get the data at the real time at this day. We have.
Keophousone Phonhalath: We we plan also thank you that we will do in the future. Thank you.
Sudjit Karuchit (SUT): Okay, thank you.
Sudjit Karuchit (SUT): I understand your limitations.
Sudjit Karuchit (SUT): But but just to just to
Sudjit Karuchit (SUT): give you
Sudjit Karuchit (SUT): to be aware of. When you make comparison it. It's like,
Sudjit Karuchit (SUT): the situation is worse
Sudjit Karuchit (SUT): than actual
Sudjit Karuchit (SUT): actual situation, right?
Sudjit Karuchit (SUT): I mean, if you include
Sudjit Karuchit (SUT): the nighttime
Sudjit Karuchit (SUT): concentration in the average.
Sudjit Karuchit (SUT): your your crafts will will be
Sudjit Karuchit (SUT): lower.
Sudjit Karuchit (SUT): It's not
Sudjit Karuchit (SUT): going to be like 200 or something.
Sudjit Karuchit (SUT): I guess. So
Sudjit Karuchit (SUT): that's 1 one thing I think
Sudjit Karuchit (SUT): is important.
Keophousone Phonhalath: Yes, thank you. I will do that in the future. Yes.
Ryan Chartier: We have any other questions at this point.
Ryan Chartier: So now we're on the agenda. We're scheduled for a discussion.
Ryan Chartier: I think.
Ryan Chartier: Matt, in the interest of time. Do you want to do? Or, Matthew, do you want to go over some of your questions? I
Ryan Chartier: I think you had these at the end of your slides at least the version I looked at
Ryan Chartier: the machine learning one, I I think, would be a good conversation starter, and actually
Ryan Chartier: thinking about being able to differentiate sources. The purple air does output data and different size bins not necessarily on their website. But if you use an Sd card version. Which case you may be able to differentiate traffic pollution from, say.
Ryan Chartier: smoke, that's been traveling for multiple days.
Ryan Chartier: I'm guessing a machine learning approach would be needed for that.
Ryan Chartier: But I think
Ryan Chartier: I think you're
Ryan Chartier: you're thinking on a larger level. Correct? Do you wanna
Ryan Chartier: start the discussion off with machine learning
Ryan Chartier: and
Ryan Chartier: what you were hoping to get out of the discussion here within the group.
Matthew Perkins UN ESCAP: Sure, actually happy. To go in whatever direction is is most suitable. I think there's been a very enriching discussion with lots of follow ups. So no particular need to have my slide frame things. And that being said, I
Matthew Perkins UN ESCAP: would sort of summarize that I think machine learning is very helpful for
Matthew Perkins UN ESCAP: determining sectoral level. Emissions, inventories but not necessarily specific points. For example, what percentage of the air pollution is because of industrial emissions rather than what specific factory is emitting.
Matthew Perkins UN ESCAP: There are are just some some limitations to how finely grained of an inference can be made
Matthew Perkins UN ESCAP: through those purposes. Yeah, I I think in in country, you know, there's a there's a certain tipping point on the low cost sensors where that's something to invest in this sort of growing.
Matthew Perkins UN ESCAP: going broad versus going deep. Kind of approach.
Matthew Perkins UN ESCAP: You know, in in my view, I think, some of the work that Dr. Sam Porn has done around
Matthew Perkins UN ESCAP: chemical analysis of Pm. 2.5 to infer the scale of trans boundary contribution, particularly around potassium miles. Biomass burning seems to me to be a really good idea to build on. So you know that, I think, would be an example of of where use of money to go deep would be valuable.
Matthew Perkins UN ESCAP: And then the the use of the wearable sensors to drill into more of the household exposure sensors seems like,
Matthew Perkins UN ESCAP: a really good vector as well. So that would be kind of my overarching contextualization of where machine learning can be helpful. And on that basis. What are some priorities to consider for allocating resources on the the science based policy? So
Matthew Perkins UN ESCAP: any feedback that the group might have on those principles would would certainly be very welcomed, and looking forward to following up with a number of you individually on on taking your work forward, thanks very much.
Ryan Chartier: Have you typically worked with local data scientists? Or do you have resources available to say universities in Southeast Asia that they could tap into externally and data scientists based elsewhere.
Matthew Perkins UN ESCAP: That's a good question with a bit of a complicated answer, because our lead data scientist was actually a a a quite brilliant Thai woman who was living in California. So she was doing the that a Thai National Research on Thai data from the other side of the planet and that was very, very effective. You know that being, said I, I do also, you know, acknowledge that I think there certainly is.
Matthew Perkins UN ESCAP: the level of human capacity amongst the countries represented in this room to be doing that scale of data science locally. In in my view, it's not the the skills of the researchers. It's more the availability of the data the availability of resources to support that data science
Matthew Perkins UN ESCAP: and the capacity of the decision making institutions, usually government, to take those works forward.
Matthew Perkins UN ESCAP: but I would certainly be very interested to hear from the researchers themselves on whether or not they agree with my opinion about what it's like to be a researcher in Southeast Asia. That's my perspective.
Ryan Chartier: Any comments from anyone on the team.
Somporn Chantara: Yeah, I would like to add up to what Matthew mentioned about that
Somporn Chantara: situation of research in South Asia, particularly in Thailand. Okay? So I I myself, I it's quite difficult now to ask for the budget from their
Somporn Chantara: the government to go in detail in a deeper size, particularly in the air pollution side. So they are looking more on the application of the research.
Somporn Chantara: So it means you have. Your research has to be ready to be used in the real world.
Somporn Chantara: So it's not just. They don't want us to spend money on the research in the lab.
Somporn Chantara: So it means it's quite difficult for us also to to take care of both sides. So we have to go deep in size, and we also have to sell our research to be applied to be used in the real world. Things like that.
Ryan Chartier: Thank you.
Ryan Chartier: and I just have one more discussion question that I think I'm going to sign off, and I'll I'll let
Ryan Chartier: you all continue the discussion. If you think that's that's useful.
Ryan Chartier: just my questions around the role of education in, you know, promoting better air quality in Southeast Asia is.
Ryan Chartier: There's a push
Ryan Chartier: from a lot of
Ryan Chartier: lot of places in the Us. To start educating people on air quality and even how to measure air quality at younger ages. Sometimes, all the way down to to primary school,
Ryan Chartier: deploy sensors in the classroom.
Ryan Chartier: children can look at how the air quality changes based on what they're doing. Or you know, if you're looking at vocs, what you release into the air
Ryan Chartier: is
Ryan Chartier: air quality, and some of the health effects is that typically taught at any stage
Ryan Chartier: in Southeast Asia that you're aware of within schools.
Ryan Chartier: So starting to teach kids early about the hazards of air pollution and what they can do to mitigate some of those on a personal level.
Ryan Chartier: Or is that something that is rarely brought up or taught at young ages
Ryan Chartier: outside of, say, you know, university or academic settings for for much older
Ryan Chartier: folks.
Ryan Chartier: Excuse me.
Somporn Chantara: Men.
Somporn Chantara: Yes, I agree.
Somporn Chantara: Yes, we should start at the primary school, or even younger.
Somporn Chantara: for children to learn about the air quality. And how important
Somporn Chantara: do we have to improve our and
Somporn Chantara: for the next generation. So in Thailand, for example, we have various Kai projects working with the school children
Somporn Chantara: to teach them how to
Somporn Chantara: how to protect themselves and learn how to read a data.
Somporn Chantara: For example, the concentration, RPM. 2, 5, 5 was
Somporn Chantara: translated to color like what we used with the Api.
Somporn Chantara: and then they learn what the meaning of that. And how how do they
Somporn Chantara: act when, when we have the critical level of evolution, things like that. So I think it's very important to educate them at a young age.
Ryan Chartier: Yeah, it seems like, until there's large scale interventions that really help reduce
Ryan Chartier: exposures that
Ryan Chartier: some, you know, behavioral change or exposure mitigation on the personal level may be useful to to reduce lifetime exposures or chronic exposures.
Ryan Chartier: especially when levels are so high and certain months. You know, focus could be made, you know, on that time period, what what can people start doing at a younger age to just reduce their their lifetime, exposure, lifetime, dose to particular matter.
Ryan Chartier: Something to to think about. But on on that note I'm going to sign off. I'll let the Aqc. Team continue the discussion.
Ryan Chartier: and then I'll I'll just take a look at the recording tomorrow when I have some time. But thank you, everybody so much for for joining and participating
Ryan Chartier: Aqc. Team been fantastic throughout this whole process, and I will be in touch offline with a number of you in the coming week. So thank you very much, and have have a great rest of your day.
Somporn Chantara: Thank you very much, Brian.
Ryan Chartier: Bye. Thank you.
Hong Le: Here, by.
Somporn Chantara: Bye. Thank you.
Keophousone Phonhalath: Bye, bye.
Hung NGO Vietnam: Bye, bye, Ryan.
Somporn Chantara: Now, Kate.
Somporn Chantara: so shall we continue, or
Somporn Chantara: do you have any points to.
Hung NGO Vietnam: So far.
Hung NGO Vietnam: Yeah, the idea here that we have 5 as a yeah. And I think that we should keep with us in in in general.
Hung NGO Vietnam: And I, I I I lean on the the, the the microl, and the
Hung NGO Vietnam: yeah, the advanced condition in in each of my Thailand.
Hung NGO Vietnam: So we we we can for be the forelower in in in the next thing. But the
Hung NGO Vietnam: I saw that right now. Yeah. He challenged it to find the funding. But there
Hung NGO Vietnam: if we can have the regional impact, we and have a fight.
Hung NGO Vietnam: So we we should keep in touch in in in somehow. I'm Steve, the the academic advisor position at the University.
Hung NGO Vietnam: And there are there are a lot of academic women resource it out there that can can can can support.
Hung NGO Vietnam: And I will link to to to keep in touch with you in Rgi. And how how can I in Vietnam, until discuss that we can use a local tensor system for for some study.
Hung NGO Vietnam: and it would be nice if you can focus on the next generation. The the children as a school.
Hung NGO Vietnam: And yeah for school. It's much easier than we do the research on the modeling and that monitoring that treatment and and entering. Yeah.
Somporn Chantara: Yes, I agree. The next step is that how we can maintain our local sensors to work for us in the long term. So for the maintenance issue. We need some budget to to do that. And today we have double state with us. Also, his team can support him.
Somporn Chantara: Our team in the future in terms of maintenance, but not in terms of the budget. Maybe some of no knowledge sharing or things like that.
Hung NGO Vietnam: Yeah, we personnel can keep the system in in one year more. And let's see after. But
Hung NGO Vietnam: at least we can keep the system up to the end of this year.
Somporn Chantara: Okay.
Somporn Chantara: yeah, how about in Louse?
Somporn Chantara: I think, Gail, do you think the maintenance issue will be
Somporn Chantara: a problem?
Keophousone Phonhalath: Yes, the the maintenance will be the problem, as now, as I mentioned, because some employee
Keophousone Phonhalath: we try to contact. But they don't reply or get my call. So it's quite yeah. The situation of one. And last year, also, we got one problem at the
Keophousone Phonhalath: deploy at whole panel, so that they've got problem with the equipment.
Keophousone Phonhalath: But when they
Keophousone Phonhalath: transport to us, and then I check the 5 days, no problem I sent back, so that that was work again. So I think this
Keophousone Phonhalath: it can be. And the other one is the
Keophousone Phonhalath: the Internet, also that they me need more to to get actually actually rt, also for keep us this budget already. But if we extend more work, I think that need more budget for for that work.
Keophousone Phonhalath: Yeah.
Keophousone Phonhalath: yes.
Somporn Chantara: Are there any opinion or comments from the others?
Somporn Chantara: Actually, I'm very interesting to I I like to cooperate with our team to maybe
Somporn Chantara: collect more samples, not not just always measure the concentrations, but
Somporn Chantara: sampling the real samples or further analysis in the lab.
Somporn Chantara: And we can, we can get like.
Somporn Chantara: maybe ask for more budget.
Somporn Chantara: Later I will figure it out and let you know about about that. But I yeah.
Hung NGO Vietnam: Yeah. 1 one thing more that we we didn't mention before about the publication of the data, what we have been doing so far
Hung NGO Vietnam: the publication
Hung NGO Vietnam: because we, we need to positioning our activity. And they know that we have the system. And it has a data.
Hung NGO Vietnam: And we can couldn't make it in in the the last the last year. But
Hung NGO Vietnam: If some other can interact, we can have some.
Somporn Chantara: To discuss with Brian. Because, it's.
Hung NGO Vietnam: See the author right here.
Somporn Chantara: Download. Yeah, to download the the data from the propane. Now.
Hung NGO Vietnam: Hmm, okay.
Somporn Chantara: Okay. Any other
Somporn Chantara: idea, or commence.
Keophousone Phonhalath: And again, I also after this we will have other student to work, and
Keophousone Phonhalath: we would like to how to say, to back up the data in previous time. So is if they, there is any people that from see from University that can help us to
Keophousone Phonhalath: to the upload the data in previous time. I mean, yeah, that.
Somporn Chantara: Upload or download. You mean download right.
Keophousone Phonhalath: Download data, not upload the download data. Yes, in previous time.
Somporn Chantara: I think we can consolidate Ryan.
Keophousone Phonhalath: Oh, okay.
Somporn Chantara: So, as I said, Car, do you have any idea on this?
Somporn Chantara: If you like to download some previous data from the censors.
Sate Sampattagul: Actually, we can access to to website.
Hung NGO Vietnam: Have to pray.
Sate Sampattagul: Aware. And we might download the previous data from the system.
Sate Sampattagul: I think my team have already
Sate Sampattagul: already done the download before. Maybe we can share with you the instruction how to download the data.
Keophousone Phonhalath: Yes. Yeah.
Hung NGO Vietnam: Yes, yes.
Hung NGO Vietnam: please. Thank you.
Somporn Chantara: Okay, yeah.
Somporn Chantara: so we can contact be by email later. Yeah.
Keophousone Phonhalath: Yes, now.
Somporn Chantara: The high. Some normally. Take shot on that. Yeah.
Somporn Chantara: okay.
Somporn Chantara: any other comments before we finish for the workshop today?
Somporn Chantara: Okay, no more.
Hung NGO Vietnam: Yeah, we just keep in touch now and forever. I mean.
Somporn Chantara: Okay, thank you. Everyone
Somporn Chantara: for joining. And I think this today workshop is very useful for all of us
Somporn Chantara: and help us understand each other more and learn a lot. Yeah, thank you everyone again and see you again next time. Thank you, Matthew, for the clapping and joining.
Hung NGO Vietnam: Thank you again for support. And the tie team that leading the project. Very well. We've been giving tests. Thank you.
Keophousone Phonhalath: Oh, thank you!
Somporn Chantara: Thank you and goodbye for today.
Matthew Perkins UN ESCAP: Thank you. Thank you very much. Thank you.
Nuttipon Yabueng: Cube.
