The Bangkok Metropolitan Administration’s Air Pollution Coordination and Resolutions Center reported the levels of particulate matter 2.5 micrometers and less in diameter (PM2.5) at 44-77 micrograms per cubic meter of air in 24 hours.
PM2.5 breached the 50μg safe threshold in 54 areas. The highest level of 77 μg/m³ was in Sai Mai district, followed by 74 μg/m³ in Nong Chok district, 71 μg/m³ in Prawet district and 68 μg/m³ in Thawi Watthana district.
The center said smog levels measured at most weather stations in the capital were harmful to health. It advised the general public – especially elderly people, children and those with respiratory illness and eye irritation – to reduce outdoor activities and wear protective gear.
