Sky in northern capital turns brownish as
Air Quality Index gives it ‘unhealthy’ reading.
CHIANG MAI yesterday ranked third on the global list
of cities with worst air pollution,
based on Air Quality Index (AQI) records,
by an internationally recognised AirVisual platform.
Chiang Mai’s AQI scores stood at 194 as of press time,
a level considered “unhealthy”.
Any figure beyond 200 is very unhealthy.
Across the world, Chiang Mai’s severe air pollution was
just behind the Indian capital of New Delhi (AQI 215)
and Pakistan’s Lahore (AQI 197).
AirVisual prides itself for making the world’s largest
air-quality data available at one’s fingertips.
In Thailand, Chiang Mai is one of many provinces
in the North struggling with smog,
including Lampang, Phrae, Lamphun and Nan.
