Illegal levels of fine dust were detected in 16 out of Thailand’s 77 provinces, mostly in the North and the Northeast, while great atmosphere was recorded in some southern provinces as well as Bangkok and Samut Prakan.

The Geo-Informatics and Space Technology Development Agency ( Gistda ) discovered at 10am on Sunday that the unsafe levels of particulate matter 2.5 micrometers and less in diameter ( PM2.5 ) were at the orange level ( starting to have an impact on health ).

No provinces were at the red ( hazardous-to-health ) level. Over the course of 24 hours, the healthy level is set at 37.5 microgrammes per cubic meter of heat.

The orange levels of PM2.5 in the 16 provinces ranged from 37.8 to 43.7µg/m ³ in Amnat Charoen, Bueng Kan, Buri Ram, Kalasin, Kamphaeng Phet, Lampang, Lamphun, Loei, Nakhon Phanom, Nakhon Ratchasima, Phichit, Prachin Buri, Sa Kaeo, Sukhothai, Surin and Tak.

Eleven provinces had good air quality as their PM2.5 levels ranged from 20.5 to 24.9µg/m ³ ( green levels ). In an ascending attempt of PM2.5 degrees, the 11 counties – mainly southern – were Yala, Narathiwat, Pattani, Bangkok, Samut Prakan, Trang, Satun, Phatthalung, Songkhla, Krabi and Ranong.

Fifty different regions had mild air value, represented by bright levels of PM2.5 ranging from 25.8 to 37.4µg/m³. The counties included Ayutthaya, Chiang Mai, Chiang Rai, Kanchanaburi, Mae Hong Son, Thailand, Prachuap Khiri Khan and Surat Thani.
