BANGKOK, Thailand – At 7AM on 23 January, the Bangkok Air Quality Information Center reported that the city’s PM2.5 air pollution levels averaged 71 micrograms per cubic meter (µg/m³), exceeding the national safety standard. Fourteen districts in Bangkok have been classified as “red zones,” indicating unhealthy air quality that poses significant risks to public health.
The districts with the highest PM2.5 levels include Nong Khaem at 96.6 µg/m³, Bang Khun Thian at 85.9 µg/m³, and Phasi Charoen at 83.4 µg/m³. Other districts such as Thawi Watthana, Nong Chok, and Bang Na also recorded elevated pollution levels, ranging from 75 to 81 µg/m³.
The overall air quality in Bangkok is categorized as having “initial health effects,” with areas in Thonburi South experiencing the worst conditions, reaching up to 96.6 µg/m³. Northern Bangkok, Central Bangkok, and Eastern Bangkok have also reported worsening air quality, with PM2.5 levels between 55.5 and 81.4 µg/m³.
In response, Bangkok authorities have implemented stricter measures to combat pollution. Trucks that are not classified under the “Green List” are banned from entering designated control zones. Exceptions are made for electric vehicles (EVs), natural gas vehicles (NGVs), and trucks meeting Euro 5 or Euro 6 emission standards. This policy is in effect from January 23 at 12:01 a.m. to January 24 at 11:59 p.m.
Public health recommendations have been issued, urging citizens to avoid outdoor activities and to wear protective masks when going outside. Vulnerable groups, such as individuals with pre-existing conditions, are advised to remain in clean air zones, prepare necessary medications, and follow medical advice closely. Those experiencing symptoms like coughing, breathing difficulties, or eye irritation are encouraged to seek medical attention immediately.
Bangkok residents are urged to stay informed and take necessary precautions as air pollution levels are expected to rise further. (NNT)
