Bangkok experienced the highest air pollution levels in Thailand on Tuesday, with fine particulate matter (PM2.5) concentrations reaching hazardous levels across all 50 districts of the capital, according to the Geo-Informatics and Space Technology Development Agency (GISTDA).
Bangkok stood as the only city blanketed by red-coded (seriously hazardous) levels of fine dust pollution among 63 provinces battling thick smog late Tuesday morning, according to the Geo-Informatics and Space Technology Development Agency (Gistda).
At 10 a.m. on the same day, PM2.5 levels in Bangkok averaged 88.6 µg/cu.m over 24 hours—more than double the government’s safety limit of 37.5 µg/cu.m. The worst-affected district, Bang Kho Laem, recorded levels of 96.7 µg/cu.m.
The surrounding provinces of Nonthaburi, Samut Prakan, Samut Sakhon, and Pathum Thani also reported hazardous “red” levels of PM2.5, with concentrations ranging from 79.1 to 83.6 µg/cu.m.
In contrast, 16 provinces, including Chiang Mai in the north and several southern provinces like Krabi, Phuket, and Songkhla, reported safe PM2.5 levels between 24 and 37.3 µg/cu.m. Krabi recorded the country’s best air quality.
Several other provinces recorded PM2.5 levels in the “orange” range, between 37.7 and 74.8 µg/cu.m, where air quality starts to pose health risks.
Authorities continue to monitor and address the pollution, which poses serious health concerns for residents and visitors.
