The acronym PM10 literally means Particulate Matter. The “10” corresponds to the aerodynamic diameter, or the diameter of a hypothetical spherical material with a density equal to 1 g/cm³. With the name PM10, we refer to all fine powders with a diameter equal to or less than 10 thousandths of a millimeter, or 10 µm. Standard methods for collecting PM10 and PM2.5 are reported somwhere else (EN 12341, US 40 CFR Part 53).

PM10 is listed in the World's largest and most The WHO tabulation ranks cities by the annual mean volume of PM10. meaning that a particular bad day or Hong Kong. On December 30, 2013, Hong Kong replaced the Air Pollution Index with a new index called the Air Quality Health Index. This index, reported by the Environmental Protection Department, is measured on a scale of 1 to 10+ and considers four air pollutants: ozone; nitrogen dioxide; sulphur dioxide and particulate matter (including PM10 and PM2.5).

Particle pollution is the term for a mixture of solid particles and liquid droplets found in the air. These include "inhalable coarse particles," with diameters between 2.5 micrometers and 10 micrometers, and "fine particles," 2.5 micrometers and smaller. Coal and fly ash together contribute the highest to PM10 and PM2.5 during summers-- 3,493kg/ day out of the total 37,171 kg/ day of PM 10, and 1,758kg/ day out of 18,369 kg/ day of PM 2.5, says the IIT study. the smaller the SIZE of the particulate, the greater may be the toxicity. Very small particulate (diameter less than 2.5 micrometer) is the most toxic for human being, because:

Sometimes in hot summer months, Ozone will be the main pollutant, meanwhile - in particularly sandy or dusty places, PM10 will often be the main pollutant. The main pollutant meaning that that pollutant will dictate the AQI curve. Measurements of PM10 or PM2.5 from official national/sub-national reports and websites or reported by regional networks such as Clean Air Asia for Asia and the European Environment Agency for Europe or data from UN agencies, development agencies, articles from peer PM10 and PM2.5 monitoring is not conducted in many of the non-EU countries, which makes it difficult to assess exposure in those parts of the Region. Period of coverage PM10 and PM2.5 data used in this analysis cover the period from 2004 to 2011. Particulate matter (PM10/2.5) Airborne particulate matter varies widely in its physical and chemical composition, source and particle size.
