The Pollution Control Department has warned of harmful levels of PM2.5 dust in Greater Bangkok on Monday and Tuesday and again later this weekend, because of stagnant air over the capital.
The department reported on Monday morning that over the past 24 hours the level of PM2.5 in Greater Bangkok ranged from 28-62 microgrammes per cubic metre (µg/m³) of air. The local safe threshold is 50 µg/m³, higher than most other countries.
Unsafe levels were measured in Bung Kum, Klong Sam Wa, Wang Thong Lang, Don Muang, Sai Mai, Bang Kapi, Lat Krabang, Min Buri, Thawi Watthana and Nong Khaem districts.
The department said fine dust levels would rise on Tuesday morning, drop from Wednesday to Friday due to air movement and rise again on Saturday and next Monday due to stagnant air.
