Point source 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.[1] Pollution point sources are identical to other physics, engineering, optics, and chemistry point sources and include:
- Air pollution from an industrial source (rather than an airport or a road, considered a line source, or a forest fire, which is considered an area source, or volume source)[2]
- Water pollution from an oil refinery wastewater discharge outlet[3]
- Noise pollution from a jet engine[4][5]
- Disruptive seismic vibration from a localized seismic study[6]
- Light pollution from an intrusive street light[7]
- Radio emissions from an interference-producing electrical device
