The National Environment Board (NEB) on Wednesday backed stronger measures to deal with air pollution from fine particle matter smaller than 2.5 microns (PM2.5). It ordered all 17 provinces in the North to cease burning activities until the end of April.
Siwaporn Rugsiyanon, a spokeswoman for the Centre for Air Pollution Mitigation at the Department of Pollution Control, said the level of PM2.5 had reached as high as 225 microgrammes per cubic metre (μg/m³) in some spots early this month.
