Bangkok – Air quality in the Bangkok area has improved slightly this week with the overall air quality being very good, while the northern region continues to suffer from haze due to forest fires and agricultural burning.
Air quality measurements by the Pollution Control Department on Wednesday morning showed PM2.5 levels under 50 micrograms per cubic meter in all areas of Bangkok.
While no red zones are detected in the northern region, PM2.5 readings still exceed standard levels in areas of Tak, Phayao, Lampang, Lamphun, and Chiang Mai.
Fire control officials in Phayao have erected barriers along Phra That Pong Klua and the surrounding area to prevent forest fires. Lamphun has also asked the public to refrain from driving vehicles to the provincial city hall to reduce emissions and has prepared measures to transport visitors.
