Thailand’s standard for safe levels of PM2.5 (particles less than 2.5 micrometres in diameter) is 50 micrograms per cubic metre (μg/m3), though the World Health Organisation sets it at 25 μg/m3.
Here are the PM2.5 per cubic metre readings in different parts of Thailand:
• North: 23-113μg/m3
• Northeast: 18-37μg/m3
• Central Region and West: 17-45μg/m3
• East: 12-34 μg/m3
• South: 8-28 μg/m3
• Bangkok and its vicinity: 33-73μg/m3
Meanwhile, the Bangkok Air Quality and Noise Management Division said air quality was unsafe in 10 districts of Bangkok and its vicinity. Samut Sakhon’s Muang district topped the list with 73μg/m3, followed by Bangkok's Bangkok Yai (61μg/m3) and Taling Chan districts (60μg/m3).
