BANGKOK: The air quality in most areas of the Bangkok metropolitan region exceeded the safety standard on Friday morning (Jan 31), the Air Quality Information Centre of the Bangkok Metropolitan Administration (BMA) said.
The centre reported the average PM2.5 levels throughout the city on Friday at 48.7 micrograms per cubic metre (mcg), well above the country’s standard of 37.5 mcg over a three-hour average (5am to 7am).
Yesterday’s reading at the same time was at 35.3 mcg.
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 Khaem (65 mcg), Phasi Charoen (60.3 mcg), Thawi Watthana (59.6 mcg), Taling Chan (59.1 mcg), and Khlong Sam Wa (58.3 mcg).
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. - The Nation/ANN
