The Centre for Air Pollution Mitigation has warned of harmful levels of fine-particulate dust in Greater Bangkok and the northern region next week due to a drop in wind speed.
Centre chief and director-general of the Pollution Control Department (PCD) Atthapol Charoenchansa said that concentrations of fine particulate matter measuring 2.5 microns or less in diameter (PM2.5) in all areas of the country were within the local "safe" threshold of 50 microgrammes per cubic meter of air on Saturday.
