High levels of air pollution comes back in Bangkok


BANGKOK — Suburban areas in the capital according to the Pollution Control Department have high levels of air pollution at 7 am today, 22 October.

The unhealthy air in many districts of Bangkok with several reporting PM2.5 Air Quality Index of 68, is showing in the seven PCD monitoring stations.

Districts that are affected by high levels of air pollution are Bang Phlat, Bang Kho Laem, Bang Sue, Phasi Charoen, Pak Nam Subdistrict in Samut Prakan Province, and Mahachai Subdistrict and Om Noi Subdistrict.

In a report from The Nation, the unhealthy air may linger until 26 October due to the temperature inversion that usually occurs in winter and is marked by a reversal of the normal behavior of temperature in the troposphere, in which a layer of cool air at the surface is covered by a layer of warmer air.

These conditions will block air and dust particles from an upward movement, resulting in less ventilation for PM 2.5, the report added.

But air quality will improve on 27 October after the cool air from North flows down to the central region.
