Forest fires that have been burning around Doi Phra Baht in Muang Lampang since Sunday night are contributing to the dense haze clinging to the province.
Seventy-five officials and seven “We Love the King” volunteers were on Monday trying to contain the flames within an expanse of several kilometres.
In the tambon of Kluay Phae, a forest blaze threatened Wat Doi Moung Kham but was extinguished by area residents.
Lampang has four Pollution Control Department air-quality-measuring stations, all reading unsafe levels of PM2.5 – airborne particulates 2.5 microns or less in diameter – on Monday morning of 60-93 micrograms per cubic metre of air. The safe level is 50 micrograms.
PM2.5 in Sop Pad, Mae Mo district, hit 93 micrograms and was also bad in two other tambon in Mae Mo.
Lampang has had unsafe levels of PM2.5 for nine days, including five consecutive days from February 7-11.
