The Pollution Control Department reports dust problems in Bangkok have abated thanks to rainfalls in several areas.
Director of the Air Quality and Noise Management Bureau, Thalearngsak Petchsuwan explained that the recent surge in dust particle volume in the capital city resulted from a sudden rise in temperature, causing fine particulate matter (PM2.5) to accumulate and surpass the standard level of 50 micrograms per cubic meter.
PM 2.5 levels were alarming in heavily congested areas, posing a health risk to people, especially those who already have respiratory problems. Dust particles were most noticeable on Wednesday as they merged with thick fog. However, rainfall in several areas has settled the dust. The situation has returned to normal.
The Pollution Control Department still cautions that the dust problem might recur and that people should wear face masks when going outdoors. Health effects of exposure to dust will be minimal if it is not contaminated with hazardous substances.
