Airborne Particulate Matter

Particulate matter (PM) in the ambient air is a key indicator of air pollution. It can be suspended over long time and travel over a long distance in the atmosphere. It can cause a wide range of diseases that lead to a significant reduction of human life. Because of the potent role of PM and its associated pollutants, detailed knowledge of their effects on the environment in general, and human health in particular, is of primary importance.
