Yom Posted December 28, 2020 Author Share Posted December 28, 2020 (edited) 5 hours ago, VocalNeal said: What standard do you use for your basis of good or bad? Thanks for your question, Mr. VocalNeal. Is there any standard anywhere for good and bad? You are referring to this picture? There are so many sophisticated sensors these days all over the world and so many different models to calculate, to represent, that you must decide for yourself, what to accept, what to trust, what's good, what's bad. 'bad' Under the given circumstances (what is feasible in TH?) 50 to 60 ug/m3 PM2.5 or AQI 137 to AQI 153 is bad till very bad. Everything above I usually call crazy. Even if you usually can't see or smell the air pollution. There are different limits all over the world. I would prefer US standards, better than EU or Thailand, while China seems to be the bad boy. Please have a look at the decreasing ug/m3–PM2.5-numbers over 19 years in the US. - Thailand will never reach this goal. At least not in my lifetime. https://www.epa.gov/air-trends/particulate-matter-pm25-trends To add: US 'National Sstandard' ~ 12ug/m3 that means an AQI 50. People often confuse the names/units. ***************** Edited December 28, 2020 by Yom 1 Link to comment Share on other sites More sharing options...
VocalNeal Posted December 29, 2020 Share Posted December 29, 2020 OK cheers. Most posts or sites seem to concentrate on dust ie. PM2.5 which is mostly construction or blown from outside countries except of course in BKK. (condo construction etc.) Link to comment Share on other sites More sharing options...
