Air pollution eases in North, but increases in Bangkok
Smog has receded in the North, but the level of particulate matter smaller than 2.5 microns (PM2.5) has increased in the Bangkok metropolitan area, where it is lingering around the safe limit of 50 micrograms per cubic metre of air.
The measurement of PM2.5 levels as reported by the Pollution Control Department and international air-quality monitoring website aqicn.org on Saturday revealed that pollution in the Northern region had decreased overall. Most areas had PM2.5 levels lower than the safe limit, with the exception of Tak’s Mae Sot district, which had a daily average PM2.5 level of 52.77 micrograms.
