The looming cold spell has brought relief to Bangkokians from the heat but, at the same time, posed a health hazard from the accumulation of particulate in the atmosphere.

Pollution Control Department chief Mrs Sunee Piyaphanpong explained on Friday (Feb 2) that the cold weather in Bangkok coupled with humidity led to the accumulation of particulate matter in the air which would pose a health threat to risk groups such as people with heart problem or respiratory problem if the amount of particulate matter, including PM10 and PM2.5 was above safety standard.

Report of air quality in Bangkok on Friday at 3 pm showed the amount of PM10, or particulate matter smaller than 10 microns, was within the safe level (100 microgrammes/cubic metre) at all monitoring stations while the amount of PM2.5 particulate was measured at between 33-54 microgrammes/cubic metre which was well within the 50 microgrammes/cubic metre safety standard.

Only in Thon Buri district and the area along the Intharapitak road that the PM2.5 level was above the 50 microgrammes/cubic metre safety limit.

Members of the public can keep themselves abreast with the report of air quality in Bangkok by clicking into the Pollution Control Department's website at or the department's Facebook page.

To prevent the air quality from getting worse, the department has sought cooperation from all stakeholders to refrain from burning garbage, to reduce emissions and to contain dust particles at construction sites.
