Bangkok: The Pollution Control Department has issued a critical warning to 37 provinces, cautioning them about PM2.5 levels that have surpassed standard limits. The department emphasizes the necessity of continued monitoring, particularly from March 7-10, as particulate matter levels are expected to escalate in northern, central, and Bangkok areas.
According to Thai News Agency, the Air Pollution Control Communication Center released data on March 6, 2026, at 7:00 AM, indicating that air quality in numerous regions remains above permissible levels. The provinces identified for heightened vigilance include Pathum Thani, Bangkok, and Nonthaburi, among others. Detailed reports indicate that these areas need rigorous monitoring to address the air quality challenges effectively.
The report outlines specific regional conditions:
- In the northern region, PM2.5 levels are significantly above the standard, with readings between 20.7 and 76.9 micrograms per cubic meter.
- The Northeast region, in contrast, boasts good air quality, with PM2.5 levels ranging between 9.2 and 28.7 micrograms per cubic meter.
- Central areas report elevated PM2.5 levels, from 30.0 to 54.4 micrograms per cubic meter.
- In the Eastern region, three localities show readings from 19.7 to 43.3 micrograms per cubic meter, exceeding standard limits.
- The southern region has two areas with PM2.5 levels between 19.6 and 44.0 micrograms per cubic meter.
In Bangkok and its vicinity, collaborative monitoring by the Pollution Control Department and the Bangkok Metropolitan Administration reveals that most areas are not meeting air quality standards, with PM2.5 levels between 30.1 and 51.3 micrograms per cubic meter.
The Air Pollution Communication Center advises the public to take precautions such as monitoring health, minimizing outdoor activities, or using protective equipment. Vulnerable individuals are urged to avoid outdoor activities, and medical consultation is recommended if unusual symptoms occur. Outdoor activities are particularly discouraged in areas identified as red zones, where air pollution is severe.
The forecast for March 7-13, 2026, predicts rising PM2.5 levels in Bangkok, surrounding areas, and 17 northern provinces from March 7-10. The central and eastern regions may also experience increases during this period, while the northeastern region is expected to see improvements. The southern region, however, continues to maintain good air quality.
Residents are encouraged to use the Air4Thai and AirBKK applications to access real-time air quality data, enabling them to make informed decisions and safeguard their health.
