Bangkok air pollution spikes as 35 areas exceed safe PM2.5 levels

Bangkok faced a spike in PM2.5 pollution levels, with 35 areas registering unhealthy air quality, prompting swift action from City Hall. The Bangkok Metropolitan Administration (BMA) issued warnings to help residents mitigate health impacts from the pollutants.

PM2.5, or ultra-fine dust particles, exceeded the safe threshold of 37.5 micrograms per cubic metre (µg/m³) in several areas, according to AirBKK, BMA’s air quality information centre. As of 7am yesterday, November 10, PM2.5 levels across the city ranged from 26.5 to 53.4 µg/m³.

Nong Khaem, Thon Buri, Klong Sam Wa, and Thawi Watthana recorded levels of 43.8 µg/m³ or higher, placing them among the city’s most polluted zones. Dusit slightly surpassed the safe limit with 37.6 µg/m³.

In these 35 zones, PM2.5 levels surpassed the safe threshold, earning them an orange status on the air quality monitoring system. Other parts of Bangkok maintained moderate air pollution quality.

The primary cause of the pollution was stagnant air, resulting from inadequate ventilation in the city. In response, the BMA’s Department of Environment urged relevant agencies to activate this season’s operational plan to reduce dust levels, reported Bangkok Post.

Residents, particularly those with underlying health conditions, were advised to wear facemasks outdoors, avoid strenuous outdoor activities, and monitor for symptoms like coughing, shortness of breath, and eye irritation. Medical advice is recommended if symptoms persist.
