BANGKOK (NNT) - The level of PM 2.5 airborne particulate matter has risen in seven areas of Bangkok and neighbouring provinces, reports the Pollution Control Department.
The Pollution Control Department (PCD) Director General, Pralong Dumrongthai today revealed PM 2.5 readings in Bangkok and neighboring provinces, are currently at moderate to health-affecting levels, with the overall PM 2.5 concentration between 29-79 micrograms per cubic meter.
The dust level was found to be higher than standard in seven areas, namely Bang Phlat, Bang Kho Laem, Bang Sue, and Phasi Charoen districts in Bangkok; Pak Nam subdistrict in Samut Prakan; and Maha Chai and Aom Noi subdistricts in Samut Sakhon. Air quality in these areas is starting to have health effects, with a higher dust concentration than yesterday.
The Meteorological Department forecasts that the high pressure system currently prevailing over Thailand will weaken over 22nd-26th October, resulting in weak winds or still air in the mornings. Temperature inversion could also occur, causing morning smog. Air ventilation during this period may be compromised causing particulate matter to be suspended low in the air. The situation is expected to improve from 27th October due to winter winds prevailing over Bangkok and neighboring provinces.
The PCD chief has stressed that the general public should refrain from any open air burning, take their vehicles for proper maintenance to prevent black exhaust smoke emissions, opt for public transportation instead of using private vehicles, and report any public vehicles emitting black smoke. Construction sites and factories are asked to help minimize their air pollution emissions to help mitigate the situation.
