Don’t take toxic air problem lightly
If April is the month of Songkran, surely March is known for its pollution, especially in Northern Thailand, at its peak. With burning season in full swing, air quality readings in cities like Chiang Mai, Chiang Rai, and Pai have become rather unsettling — yet not surprising.
Over the past two weeks, Chiang Mai’s average daily PM2.5 level has hit 172.6 µg/m³, according to aciqn.org. But if that wasn’t bad enough, in the rugged hills of Mae Hong Son province, towns like Pai have seen readings as high as 400 µg/m³.
