Point source pollution
A point source of pollution is a single identifiable source of
area source). 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]
- construction sites) as point sources.[4]
- Noise pollution from a jet engine[5][6]
- Disruptive seismic vibration from a localized seismic study[7]
- Light pollution from an intrusive street light[8]
- Radio emissions from an interference-producing electrical device
