Hazardous: Chiang Mai again leads the world in air pollution
Chiang Mai is back on top of the world’s list of most air-polluted cities, according to the AirVisual.com website.
AirVisual reports at 1.45pm that the air quality index (AQI) of Chiang Mai on Saturday stands at 471 (##!!??!!) , much higher than the 100 AQI safety standard (the WHO lists the safety limit as 50 on the AQI scale). It’s been about 350 all day today.
In its six scale listings Chiang Mai is now listed at the bottom as ‘Hazardous’, the scale doesn’t go any lower.
The northern capital has been covered with white, mostly bushfire smoke and smog, for almost two weeks prompting Chiang Mai residents to wear N95 air-filter marks outdoors. Or stay indoors.
The Chiang Mai University, the Rajamangala University of Technology Lanna and Chiang Mai provincial administration confirmed that the air quality in the city remained critical.
