Air pollution hits hazardous levels in North, Northeast
Air pollution intensified in the North and Northeast, as the level of particulate matter smaller than 2.5 microns (PM2.5) was found to have reached harmful levels in many provinces. Data from the Pollution Control Department (PCD) air quality monitoring system yesterday showed that the daily average PM2.5 levels in Chiang Mai, Khon Kaen and Lampang had risen beyond Thailand’s safe level of 50 micrograms per cubic metre of air. PM2.5 measurements in those provinces were at 80.65, 64.95 and 50mg respectively.
