Point source air pollution happens when a pollutant comes from a large stationary source that is inventoried individually. e.g. Power plant
Mobile or on-road mobile pollution comes from vehicles that ride on roads e.g. cars, trucks, motorcycles
Nonroad mobile pollution comes from vehicles that do not ride on roads. e.g. construction equipment, boats, airplanes, trains.
The term area source describes small stationary sources of pollution that have emissions calculated collectively, not one by one e.g. dry cleaners, gas stations.
