Bangkok: Bangkok is grappling with alarming air pollution levels as PM 2.5 dust particles reach red-level concentrations in six areas, posing significant health risks. An additional 64 areas have been identified at the orange level, indicating a potential health impact. Authorities are urging residents to wear masks during outdoor activities to mitigate health risks.
According to Thai News Agency, the Bangkok Air Quality Information Center has reported that particulate matter measuring no more than 2.5 microns (PM 2.5) has been recorded at concerning levels across the city. As of Wednesday, January 22, 2025, at 7:00 a.m., the 24-hour average of PM 2.5 was measured at 45.7-85 micrograms per cubic meter (µg/m3). This measurement surpasses the standard threshold of 75.1 µg/m3 in six critical areas, reaching levels that adversely affect health.
The six affected districts include Nong Khaem, with PM 2.5 levels at the intersection next to the police station on Ma Charoen Road, Phetkasem 81, reaching 85.0 µg/m3. Bang Khun Non District recorded a level of 80.6 µg/m3 in front of the Bang Khun Non Railway Police Station, while Thawi Watthana District saw 80.0 µg/m3 at the entrance to Sanam Luang 2. Bang Khun Thian District reported 79.3 µg/m3 inside the district office, and Phasi Charoen District recorded 79.2 µg/m3 near Siam University.
The persistent air pollution is attributed to poor ventilation and continuous surface-level inversions, which have restricted the dispersion of pollutants. It is projected that the PM 2.5 levels will increase and stabilize from January 22 to 24, before slightly decreasing between January 25 and 28 due to improved ventilation conditions. Residents are advised to remain cautious and take preventive measures to protect their health during this period.
