Adefolake: Environmental Effects of Dust like soot & other Particulate Matter

Particulate matter commonly known as PM or particle pollution can come in form of smoke, dust, dirt or soot.

The two common categories are PM10 and PM2.5, PM2.5 is fine particle that has a diameter of about 2.5 micrometers or smaller; while PM10 is inhalable particles with a diameter of 10 micrometers or less.

Visible examples of PM10 are dust and smoke, but over 90% of particulate matter cannot be seen with the naked eyes, which would require an electron microscope.
