Area source (pollution)

From Wikipedia, the free encyclopedia

Area sources emit a substance or radiation from a specified area. For example, area sources of air pollution are air pollution sources which operate within a certain region. Locomotives operating on certain tracks or paths are examples of a line source, whereas locomotives operating within a railyard are an example of an area source of pollution.

Other area sources of pollution are:

• Multiple flue gas stacks within a single industrial plant
• Open burning and forest fires
• Evaporation losses from large spills of volatile liquids
• Surface runoff of rainfall or irrigation water
