You’ve likely seen the term PM10 floating around when researching air pollution and particulate matter. While PM10's smaller counterpart, PM2.5, often gets more buzz, PM10 is still a significant health threat and air pollutant. PM10 is just a form of air pollution composed of tiny particles, right? Seems pretty self-explanatory, but there is more to the story.

Particulate matter varies in size (i.e. the diameter or width of the particle). PM 2.5 means the mass per cubic metre of air of particles with a size (diameter) generally less than 2.5 micrometres (µm). PM 2.5 is also known as fine particulate matter (2.5 micrometres is one 400 th of a millimetre).

PM 10 is particulate matter 10 micrometers or less in diameter, PM 2.5 is particulate matter 2.5 micrometers or less in diameter. 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.
