Summer storms help ease air pollution in northern Thailand

Air pollution in northern Thailand improved as summer storms helped clear the haze that had plagued the region during the last three months, government reports showed.

The Pollution Control Department (PCD) reported Tuesday that PM 2.5 density in the country's northern provinces was raging between 32 and 61 micrograms per cubic meter, with only five areas recording higher levels than the national safe limit of 50 micrograms.

Over the weekend, summer monsoon winds hit the country's northern region and notably eased the intense air pollution, with readings in some areas down to green levels, said PCD official Sakda Tridech.

Beginning Tuesday, the air quality index in the north will further improve as strong winds and rains throughout the country would help dissipate the haze, Sakda said.

However, he said hotspots from agricultural burnings and forest fires, the main causes of air pollution, still need to be monitored in the northernmost areas.

The lasting air pollution in northern Thailand, with the popular tourist destination of Chiang Mai recording over 90 days of unhealthy air quality this year, has not only posed a health hazard to local residents but also cast a shadow over tourism.
