MAE HONG SON (The Nation) – Mae Hong Son governor Sirirat Chamupakarn has instructed village wildfire-watch teams to remain vigilant even though the province’s 61-day ban on outdoor fires ended on Tuesday and the level of fine dust particles in the air was below the safe limit for the first time in two months.
The Pollution Control Department (PCD) at 9 am yesterday put the 24-hour average of PM2.5 – airborne particulates 2.5 microns or less in diameter – at between 24 and 114 micrograms per cubic meter of air in nine northern provinces.
