Particulate matter, also known as particle pollution or PM, is a term that describes extremely small solid particles and liquid droplets suspended in air. Particulate matter can be made up of a variety of components including nitrates, sulfates, organic chemicals, metals, soil or dust particles, and allergens (such as fragments of pollen or mould spores).

PM 2.5 is generally described as fine particles. By way of comparison, a human hair is about 100 micrometres, so roughly 40 fine particles could be placed on its width. PM 10 and PM 2.5 are not used for any application. 2020-10-27 · The areas where PM2.5 exceeded the 50mg safe level were the Bangkok districts of Bang Kho Laem district ((55mg) and Bangkok Yai (51mg) and Mahachai (54mg) in Samut Sakhon province. PCD chief Attapol Charoenchansa said the rising levels of PM2.5 stemmed from a low-temperature air mass that was causing the dust to linger.

Using a nationwide network of monitoring sites, EPA has developed ambient air quality trends for particle pollution, also called Particulate Matter (PM). PM 2.5 describes fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller. Under the Clean Air Act, EPA sets and reviews national air quality standards for PM.
