Eight Bangkok districts, on Tuesday, were found to have PM2.5 pollutants higher than the prescribed safe levels, the Bangkok Metropolitan Administration reported.
The Air Quality and Noise Management Division of the provincial administration reported that Nong Khaem, Klong Sam Wa, Nong Chok, Yan Nawa, Bueng Kum, Thawi Watthana, Prawet and Khan Na Yao districts were found to have hazardous levels of particulate matter 2.5 microns in diameter or smaller at 7am.
The division reported on its web page at 7am that the dust measured at air quality stations in the eight districts fluctuated between 29 to 59 micrograms per cubic metre of air while the safety level is 50mcg per cubic metre.
The division said the poor air quality might continue until Friday because of a high-pressure mass covering the upper part of the country and Bangkok.
