ChidlomDweller Posted February 18, 2018 Share Posted February 18, 2018 I see so many post and comments (also in the BP) insinuating that the Thai government underreports the pollution figures. Scoundrels as they are, here that's not the issue. The AQI is not the same as the PM2.5 measurement. The AQI is an index of how unhealthy various pollutants like PM2.5, PM10, ozone, CO2, are, to bring them on a comparable scale. PM2.5 is the average micrograms per cubic meter of this pollutant over 24 hours. Such a number on its own would tell you nothing about how unhealthy the pollution level is, nor would it allow you to compare the health hazard from, say PM2.5 to the Carbon monoxide measurment. For more info or if you don't believe me, google "relationship AQI and PM2.5". AQI is a scale of the estimated health impact, the other a physical measurement. For instance PM2.5=50micrograms/m3 corresponds to an AQI reading of 150. PM2.5=155 micrograms/m3 corresponds to an AQI of 200. The past few days the newspapers have been reporting PM2.5 readings like 60, 70, which correspond to an AQI in the 150-200 zone. No cheating or conflicting data here.

This is what I've been trying to tell people but it's all a bit too complicated for some posters. I would disagree with you on one thing though. PM2.5 is not necessarily a 24-hour average. It's usually reported as an hourly average. Link to comment Share on other sites More sharing options...
mommysboy Posted February 19, 2018 Share Posted February 19, 2018 You miss the point. By using the Thai measure the layman is led to believe that the Thai p2.5 is much lower than it actually is. Link to comment Share on other sites More sharing options...
Wallet73 Posted February 19, 2018 Share Posted February 19, 2018 I've been suffering with chronic bronchitis, asthma and very bad sinusitis for years now, everytime i leave Bangkok i start to feel better. So this time i've been out of Bangkok for nearly 5 months and my lung problems have resolved! I only have occasional asthma now. I even had a very expensive HEPA air purifier in my apartment. Thais are killing their country. Link to comment Share on other sites More sharing options...
ExpatOilWorker Posted March 3, 2018 Share Posted March 3, 2018 The wind blew most of the pollution away from Bangkok. I can now see a building that is 20 km away. Happy days are back. Link to comment Share on other sites More sharing options...
adammike Posted March 9, 2018 Share Posted March 9, 2018 I was in Bangkok for 3 nights sat to tue and it was ok, blue skies so very hot in the sun walking about but as pollution free as Bangkok gets. Link to comment Share on other sites More sharing options...
JimShorts Posted March 12, 2018 Author Share Posted March 12, 2018 The air has been decent the last few days, which was nice to finally be able to go outside again. Not sure what happened, but today the air pollution is back in full effect. Well over 150 all across Bangkok and seemingly most of Thailand as well. You can really see it today, the buildings in the distance have disappeared completely. Link to comment Share on other sites More sharing options...

To be fair on the PCD, monitoring stations do sometimes go down but they're back up again fairly soon. There are a variety of monitoring stations to choose from and the one closest to me is still showing PM 2.5 at 175. Link to comment Share on other sites More sharing options...
LALes Posted March 12, 2018 Share Posted March 12, 2018 It is brutal out there today in BKK. Looks like the worst day we had last month. Just when you thought it was safe to go outside again. Guess we're not out of the woods, yet. Link to comment Share on other sites More sharing options...

Indeed the 2.5 is again being reported - but the official government data is only PM10 reporting so always sounds much better than it is. Link to comment Share on other sites More sharing options...

TallGuyJohninBKK Posted March 12, 2018 Share Posted March 12, 2018 I'm still seeing the correct chart info including PM2.5 for Bangkok... And, it's NOT good out there. Mask and HEP:A filter time.

My point was the official reporting to the public for air pollution within Thailand is based on PM10 rather than PM2.5 - the AQI website will normally report the PM2.5 if available (it was not available for a time after 0700 today so they then revered to PM10.

There are no non government monitoring stations in Bangkok. The US Embassy has one in Chiang Mai but not here. It's not clear what you mean by 'official reporting'. The PCD has both pm10 and PM 2.5 stations and publishes the data of both. Link to comment Share on other sites More sharing options...
JoshBe Posted March 12, 2018 Share Posted March 12, 2018 I only started tracking the AQI a few months ago, but from my subjective experience, it seems that the air quality is much worse this year than it was last year. Any recommendations for an affordable air purifier for a small room (30m2)? Link to comment Share on other sites More sharing options...

I would've stayed away from a Thai brand and went with a Japanese one (Sharp, Hitachi), but an air purifier that lasts over a decade is certainly a sign of good quality.

Also that company doesn't publish the filtration efficiency of the filter they use so it's likely to be low. Link to comment Share on other sites More sharing options...

You do not want ionizer. This will cause different health issues. Blueair are the best, but very expensive. I have a few Blueair purifiers along with a few Bwells. The Bwells perform very good. I recommend getting a PM monitor, I find mine very helpful, especially when going out of the house. I have one I got in the USA, looks exactly like this one on Lazada but with a different logo. It works great. http://bit.ly/2IlZbgy Link to comment Share on other sites More sharing options...
