CHIANG MAI: The concentration of airborne ultra-fine dust particles in several northern provinces soared beyond safe limits on Wednesday, as hundreds of active fire hotspots were detected in the region.
Chiang Mai, in particular, experienced a massive drop in air quality yesterday, with levels of both the ultrafine PM2.5 pollutants and the larger, PM10 dust particles hitting levels considered to be unhealthy especially for younger children, the elderly, pregnant women and individuals with underlying respiratory and/or cardiovascular diseases.
Due to the worsening haze, residents have been advised to avoid all outdoor activities, a local source said.
