As of Tuesday, December 10, the Thai Pollution Control Department (PCD) reported unsafe levels of fine dust across six areas in Bangkok. In the morning (local time), a PM2.5 fine dust concentration at 53 micrograms per cubic meter of air was recorded in the Bang Khen Laksi, Phasicharoen, Bang Sue, Pathumwan, Bang Kho Laem, and Khlong San districts.
The situation, triggered by stagnant air and heavy traffic, is likely to continue over the coming days.
According to environmental groups, Bangkok is currently the tenth most polluted capital city in the world. Traffic congestion, railway and condominium construction, road works, and dry weather conditions are generally responsible for the worsening of air quality in the Thai capital.
A concentration of PM2.5 fine dust above 50 micrograms per cubic meter of air is considered unsafe.
Individuals in Bangkok are advised to monitor the situation, watch for updates and health advisories issued by the Pollution Control Department (PCD), limit outdoor activities until the situation normalize or wear N95 rated masks as a protection. Children and those with chronic respiratory illnesses should exercise increased caution. Individuals are advised to seek medical attention if experiencing breathing difficulties or other health concerns.
