PM2.5 in two Bangkok areas at unsafe levels
The air quality in Thailand’s capital continues to pose concerns because of the increase in PM2.5 levels, the Bangkok Air Quality and Noise Management Bureau said.
Particulate matter less than 2.5 micrograms per cubic metre (PM2.5) in the air averaged 31-54mcg per cubic metre, exceeding the 50mcg per cubic metre air quality standard in two areas -- Pra Nakorn and Wang Thong Lang.
Most of the areas in Bangkok had moderate air pollution while the pollution levels in the two areas were harmful for health.
