CHIANG MAI, May 2 (TNA) – Thick toxic smog shrouded the northern province of Chiang Mai again and its level was the worst in the world.
The Pollution Control Department reported that particulate matter 2.5 micrometers or less in diameter measured 42-58 micrograms per cubic meter of air in the past 24 hours. The safe threshold is at 50 µg/m³.
The AirVisual website reported that Chiang Mai had the worst air pollution in the world today with its air quality index at 159 points.
There were 154 hotspots in the province, showing the highest number of hotspots in the North where there were nearly 500 hotspots. The number of northern hotspots rose by 142% from yesterday, consisting of 280 ones in forest reserves and 180 others in conservation areas.
Chiang Mai provincial governor Supachai Iamsuwan said he maintained a field burning ban in the province until May 15 as local officials had yet to handle accumulated fuel substances in forests vulnerable to wildfire. (TNA)
