BANGKOK: (HRNW) Authorities in the Thai capital ordered nearly 450 schools to close on Wednesday as pollution levels reached dangerously unhealthy levels.
Bangkok, the world’s most visited city, saw levels of PM 2.5 particles at 78.3 pg/m3. A level above 35 is considered unhealthy, according to independent air quality monitor AirVisual.
PM 2.5 particles can include dust, soot and smoke and are so small they can lodge deep in the lungs and enter the bloodstream.
“Students get affected a lot by air pollution because they are exposing to outdoor all the time even waiting for the bus or just walking,” Panpimon Jumsook, a teacher at one of the schools said.
