Air quality worsens throughout Bangkok
PM 2.5 levels in much of the Thai capital come in at just inside safety standard except in five districts including Bang Khun Thian and Bang Na
The air quality in all 50 districts of Bangkok was recorded at “yellow” to “orange” levels, or moderate to starting to affect health, on Tuesday morning, the Air Quality Information Centre of the Bangkok Metropolitan Administration (BMA) said.
The centre reported the average PM2.5 levels throughout the city on Tuesday at 36.8 micrograms per cubic metre (µg/m³), slightly under the country’s standard of 37.5 µg/m³ over a three-hour average (5am to 7am).
Yesterday’s reading at the same time was at 29.1 µg/m³.
PM2.5 refers to fine particulate matter with a diameter of 2.5 micrometres or less, which can penetrate deep into the lungs and bloodstream, posing health risks such as respiratory and cardiovascular diseases.
Major sources of PM2.5 include traffic emissions, factories, forest fires, and burning of harvest leftovers.
The five districts that reported the highest levels of PM2.5 are Nong Chok (49.3 µg/m³), Bang Khun Thian (48.5 µg/m³), Thawi Watthana (48.4 µg/m³), Nong Khaem (46.3 µg/m³), and Bang Na (42.4 µg/m³).
The centre advised Bangkokians to wear facemasks, avoid spending time outdoors and work from home if possible.
Those who experience symptoms such as coughing, eye irritation or having trouble breathing should see a physician, the centre added.
Air quality can be checked daily on the AirBKK application, www.airbkk.com, Line Alert, as well as the Facebook page of the BMA’s Environment Department.
