BANGKOK (The Nation Thailand/ANN): Bangkok’s Air Quality Information Centre reported PM2.5 (fine particulate matter of 2.5 microns or less) in the capital at 07:00 on January 26, 2026, saying pollution was worse than the weekend and may affect the respiratory system.
The City Hall also warned the citizens that several zones are at levels that are beginning to affect health and advised people to take necessary steps to avoid breathing issues.
The Bangkok-wide average was 39.4 micrograms per cubic metre (µg/m³), above the standard of 37.5 µg/m³.
In health advice to the public and tourists in the city, it said:
General public: Wear protective equipment such as a PM2.5 mask when outdoors. Limit time spent on strenuous outdoor activities or exercise. Watch for symptoms such as coughing, breathing difficulty, or eye irritation.
At-risk groups: Wear a PM2.5 mask whenever outdoors. Avoid strenuous outdoor activity and follow medical advice. Seek medical attention promptly if symptoms develop.
For the record, air pollution in Bangkok usually worsens in cooler months, with traffic, industrial emissions, and seasonal crop burning adding to the toxic smog.
It has been reported that the inhabitants in the city are mainly engaged in agricultural trades, so the number of farms and related industries is high. The burning of crops, as well as the pollution and smoke output from factories, are contributing factors to the high levels of PM2.- The Nation Thailand/ANN
