CNA reports | The air quality in Bangkok has hit unhealthy levels with residents in the Thai capital and nearby provinces advised to avoid or reduce outdoor activities on Friday and Saturday, according to the Bangkok Metropolitan Administration (BMA) on Thursday (Jan 26).
In a statement on Facebook, BMA’s Environment Department said unhealthy levels of air pollutant PM2.5 are forecasted on those days.
"The public is encouraged to plan their work and activities. Particularly in areas where the air quality reaches levels that can or will impact health, it is advisable to cut down on or avoid outdoor activities,” said the department.
It added that if outdoor activities are necessary, face masks are recommended to be worn.
According to BMA, unhealthy levels of PM2.5 are also expected in Bangkok and its vicinity on Jan 31 and Feb 1 due to stagnant weather conditions.
PM2.5 is one of the deadliest forms of air pollution – tiny particles with a diameter of less than 2.5 micrometres or about 3 per cent the diameter of a human hair.
This means they can penetrate deep inside the lungs, where they either remain for long periods or pass into the bloodstream unfiltered. Long-term exposure to these particles can result in cardiovascular and respiratory diseases, and cancers.
