Of Bangkok’s 50 districts, 21 were found to have PM2.5 higher than the safety standard of not more than 37.5 micrograms per cubic meter on Thursday. This “orange” level of PM2.5 in the air can cause health problems, the Bangkok Metropolitan Administration’s Air Quality Information Centre says.
PM2.5 exceeded the standard levels also in five areas of the Northeast, three areas of the Central and Western regions, and 25 areas of Bangkok and its surrounding provinces, according to the center.
People with health issues are advised to avoid outdoor activities, particularly in areas with high levels of PM2.5.
The BMA’s Environment Department has made available information on air quality in Bangkok through various channels, including the website www.airbkk.com, mobile application AirBKK, BMA Facebook account, Line Alert, and Line official account @airbangkok.
PM2.5 refers to atmospheric particulate matter (PM) having a diameter of less than 2.5 micrometers, which is about 3% the diameter of a human hair.
