No respite for Bangkokians as PM2.5 readings continue rising


Most of Bangkok was covered in a haze of hazardous air as of 7am on Monday, with 67 air-quality monitoring stations reporting high levels of PM2.5 pollution.

PM2.5 readings were between 49 and 77 micrograms per cubic metre of air (μg/m3) in most parts of the capital. PM2.5 are dust particles less than 2.5 micrometres in diameter that can severely affect people with chronic lung and heart conditions.

Thailand’s safe standard for PM2.5 pollution is 50μg/m3, though the World Health Organisation sets it at 12μg/m3 or lower.

The top 10 most polluted areas in Bangkok as of 7am on Monday were:

• Lat Krabang Hospital (77μg/m3)

• Seacon Square shopping mall, Prawet (76μg/m3)

• Bueng Kum district office (75μg/m3)

• Big C shopping mall, Bang Na (75μg/m3)

• Bang Khen district office (70μg/m3)

• Lak Si district office (69μg/m3)
