BANGKOK — Mask on, it’s not fog. The capital on Monday morning found itself ranked as the second most polluted city in the world, according to an independent monitoring service.
Bangkok was only behind Hanoi, Vietnam this morning as the most polluted city in the world, according to data from AirVisual. The air quality was indexed at 175 on Monday 10.12am, which is considered “unhealthy.”
The crowd-sourced air monitoring service obtained the average air quality index from more than 30 privately-operated stations across the capital. Thailand’s official data offered a much gentle figure, but it still found 33 areas to be blanketed with harmful amount of particulate matter, or PM 2.5.
