Bangkok air quality improves
The air quality levels in Bangkok have improved to safe levels, according to data seen on Thursday (February 13).
The levels of PM2.5 dust (particulate matter smaller than 2.5 microns in diameter) in several districts of Bangkok and nearby provinces were in the safe zone, according to the results from 57 air-quality monitoring stations at 7am on Thursday.
The Pollution Control Department (PCD) said dust particle levels were in the range between 17 to 41mcg per cubic metre while the international and Thai safety standards are set at 25mcg per cubic metre and 50mcg per cubic metre respectively.
However, other provinces in Thailand like Khon Kaen, Nakhon Ratchasima, Chiang Rai, Loei, Phrae and Mae Hong Son still face unhealthy smog, with dust levels at between 60-70mcg per cubic metre.
