Wind and weather can carry airborne pollutants over short or long distances.
There are four sources of air pollution in the Chesapeake Bay region. Stationary sources include power plants or manufacturing facilities. Mobile sources include cars, trucks and off-road vehicles; boats; airplanes; gas-powered lawn tools; and construction equipment. Agricultural sources include farm operations that emit gases, chemicals or particulate matter. Natural sources include lightning and dust storms.
Air pollution released into the Chesapeake Bay’s airshed will eventually fall back to the earth’s surface, where it could wind up in our rivers and streams. Airborne nitrogen, for example, is one of the largest sources of pollution affecting the Bay. Just over one-third of the nitrogen polluting the Bay comes from the air.
Atmospheric deposition is the process through which air pollution settles onto land or water.
