Masked commuters have become a common sight across downtown Bangkok as the city deals with what could possibly be the worst health-threatening haze in many years. The level of PM2.5 (extra-tiny particles smaller than 2.5 microns in diameter) has exceeded the safety limit of 50 micrograms/cubic meter. Search “Bangkok air quality” on Google and you’re guaranteed to see “unhealthy” attached to the results. PM2.5 particles are the result of, according to the Pollution Control Department, the combustion of fossil fuels and the citywide construction of new train lines, worsened by current air stagnation over metropolitan areas.
These fine particles could be easily absorbed into the body, and can lead to lung and heart diseases, and cancer. All residents are advised to wear an N95 face mask when outdoors. Or stay indoors as much as you can as even these standard face masks don’t provide enough protection. In response to the issue, authorities are urging Bangkokians to use public transport (a tall order), and are installing a few public water sprinklers (don’t seem to help). With the roads packed with cars and city-wide construction at a high, there’s no telling when the smog will abate. So strap on that mask—the dust is not about to settle anytime soon.
