Killer Smog Chokes Chiang Mai

smog smoke haze air pollution chiang Mai thailand

Chiang Mai was blanketed with thick smog from forest fires, with pollution hitting twice the safe level in some areas and local officials using fountains to alleviate the pollution.

The air pollution blocked visibility and irritated eyes in Muang District for several days.

The safe threshold for particulate matter 2.5 micrometers and less in diameter was set at 50 micrograms a cubic meter of air in 24 hours but PM2.5 levels reached 120mcg at the central stadium of Chiang Mai University in Muang and 119mcg at the Pichit Preechakorn military camp in Chiang Dao District.

The Chiang Mai municipal office used fountains in its ancient moats with the belief that humidity might help reduce smoke haze. No one informed them that it’s useless.

There were 64 spots of wildfire in Chiang Mai Thursday  comprising 57 in forests and seven in farmland.
