Industrial point sources of air pollution

A point source of pollution is a single identifiable source of air, water, thermal, noise or light pollution. A point source has negligible extent, distinguishing it from other pollution source geometries. The sources are called point sources because in mathematical modeling, they can be approximated as a mathematical point to simplify analysis. Pollution point sources are identical to other physics, engineering, optics, and chemistry point sources and include:

Types of air pollution sources which have finite extent are line sources, area sources and volume sources. Air pollution sources are also often categorized as either stationary or mobile.
