Bangkok: Bangkok's air quality has reached concerning levels as PM 2.5 dust particles exceed the standard in 70 areas, posing health risks to residents.
According to Thai News Agency, the PM 2.5 concentration, measured between 37.6 and 73 micrograms per cubic meter (µg/m3), has surpassed the safe threshold of 37.5 µg/m3, reaching the orange level, which indicates the onset of health effects.
The Bangkok Air Quality Information Center reported that the highest levels were recorded in Nong Khaem District, with a measurement of 73.0 µg/m3, followed by Lat Krabang District at 68.2 µg/m3, and Khlong Sam Wa District at 67.5 µg/m3. These elevated dust levels are attributed to poor ventilation and continuous surface inversions, which are expected to persist until January 24.
Weather forecasts suggest that the concentration of PM 2.5 will rise until January 24 and then decrease as ventilation improves by January 25-26. In light of these conditions, authorities are urging residents to wear masks during outdoor activities and encouraging companies to implement work-from-home arrangements where possible.
Traffic conditions in Bangkok have been impacted, with smoother flow observed in some areas, although congestion persists. Motorcycle taxi drivers reported fewer customers, likely due to increased remote work. Despite the ongoing situation, some office workers continue to commute, either unaware of the work-from-home advisory or due to fixed in-office days.
The Bangkok Metropolitan Administration is coordinating with approximately 100,000 agencies to support the work-from-home initiative. Should PM 2.5 levels continue to rise, further cooperation from the public is anticipated to extend remote work practices until January 24.
