The map from Gistda shows levels of PM2.5 in Thailand in different colour codes on Sunday morning.
Unsafe levels of ultrafine dust blanketed 38 provinces, mostly in the Northeast and the Central Plains, on Sunday morning, according to the Geo-Informatics and Space Technology Development Agency (Gistda).
Gistda reported at 8am that unsafe levels of particulate matter 2.5 micrometres and less in diameter (PM2.5) ranged from 37.6 to 75.6 microgrammes per cubic metre (µg/m³) of air in the 38 provinces. The government-set safe threshold for PM2.5 is 37.5µg/m³.
The highest level, 75.6µg/m³, which was a red level (seriously harmful to health) was recorded in the northeastern province of Maha Sarakham.
Thirty-seven other provinces were covered with orange levels of PM2.5 …
