Air quality in Bangkok and adjacent provinces has continued to deteriorate for the second day in a row, with the amount of PM2.5 in the atmosphere of 40 areas exceeding 50 microns and reaching as high as 72 microns in the worst-affected areas, according to the 8am air quality reports from the Department of Pollution Control.

The department’s director-general, Atthaphol Charoenchansa, warned today that air quality in Bangkok could worsen, to a level which could endanger people’s health, until Monday because of the accumulation of dust caused by traffic congestion, as many Bangkok residents did not go out of town over the long weekend.
