PM2.5 Dust Levels Rise in Bangkok and Surrounding Areas
The Pollution Control Department reports that PM2.5 levels have exceeded safety standards in nine areas of Bangkok and its vicinity, with further increases expected by November 19-20.
According to a report by Prachachat Business, the Pollution Control Department has issued a warning regarding rising PM2.5 dust levels in Bangkok and its surrounding provinces. Monitoring data indicates that nine areas have already recorded levels exceeding safety standards, reaching the orange alert category. The highest concentration measured reached 44.2 micrograms per cubic meter.
Authorities have projected that the situation may intensify between November 19 and 20, 2026. This anticipated increase is attributed to a strong cold air mass moving over Thailand, which is expected to cause dust particles to accumulate closer to the ground.
For residents and travellers, this development is significant as prolonged exposure to fine particulate matter can impact respiratory health. Those sensitive to air quality issues are advised to monitor local air quality indices closely and consider protective measures, such as wearing masks, if necessary. While the current data highlights specific areas of concern, the exact duration and severity of this accumulation remain subject to meteorological changes. Official updates from the Pollution Control Department should be consulted for the most current information as the situation evolves.
