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. 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). In Thailand, Chiang Mai is one of many provinces in the North struggling with smog, including Lampang, Phrae, Lamphun and Nan. In Chiang Mai, the sky turned brownish yesterday due to the haze. Long-time exposure to air pollution can cause many health problems, and in extreme cases, it can be linked to death.
