Particulate matter (PM) or particulates are microscopic particles of solid or liquid matter suspended in the air. An aerosol is a mixture of particulates and air, as opposed to the particulate matter alone, though it is sometimes defined as a subset of aerosol terminology. Sources of particulate matter can be natural or anthropogenic. Particulates have impacts on climate and precipitation that adversely affect human health.
