Introduction to Particulate Matter

Particulate matter (PM) is airborne particles and droplets, that can be inhaled. Some PM is formed through physical motion, like pulverized dust getting wind swept, and other PM is formed through gaseous chemical reactions in the atmosphere. Particulate matter is regulated because it has negative health consequences, especially when it is small enough to travel deep into the lungs, and be respired.
