Chiang Mai among top most polluted cities

Several provinces in the northern region of Thailand face toxic smog as Chiang Mai is ranked among the world’s top 10 most polluted cities on Wednesday.

Chiang Mai climbed to the 8th position globally for major cities with pollution, according to rankings by the IQAir website.

Thirteen pollution hotspots were identified in Chiang Mai, primarily concentrated in Mae ChaemDistrict, totaling seven spots. Air quality in Thailand regularly plummets in the early months of the year as smoke from farmers burning stubble in the fields adds to industrial emissions and vehicle exhaust fumes.
