Aerosols can be classified by their source into primary aerosols (generated directly from a source into the atmosphere in particulate form) and secondary aerosols (generated by conversion of a primary pollutant in the atmosphere). They may be derived from natural sources such as fine dust and motes raised by wind, salt particles evaporated from seawater splashes, volcanic eruption scatterers, and forest combustion fumes, or from man-made sources such as combustion of fossil and non-fossil fuels, transportation, and various industrial emissions.
