According to Gistda’s report at 7am, 26 provinces suffer red levels ( hazardous to health ) of particulate matter 2.5 micrometres and less in diameter ( PM2.5 ) ranging from 77 to 135.1 microgrammes per cubic metre of air over the past 24 hours. The government-set secure lervel is 37.5µg/m³.
People in Bangkok faced the highest level of PM2.5 at 135.1µg/m³, followed by those in adjacent provinces namely Samut Sakhon ( 130.8 ), Samut Prakan ( 128.1 ), Nonthaburi ( 122.7 ), Pathum Thani ( 114.7 ) and Nakhon Pathom ( 112.8 ).
