Particulate matter (PM) is defined as fine solid or liquid matter suspended in the Earth’s atmosphere. Both natural and man-made sources contribute to airborne PM. Natural sources include smoke from forest fires and volcanic eruptions while man-made sources include automobile exhaust and smoke from power generation activities. PM is a complex mixture of elemental and organic carbon (EC and OC), inorganic compounds such as sulfates and nitrates, as well as metal compounds. Airborne PM is an important metric of air quality and amajor source of health concern in urban areas. Long-term exposure to fine PM with diameters of less than 2.5 mm is associated with increased risk of lung cancer and cardiovascular diseases, while short-term exposure is associated with cardiopulmonary diseases.
