area source

Essentially, it is an area source with a third dimension.

This theory would be the precursor of area source dispersion models.

Chaotic activity was witnessed at the airport immediately after the blast, creating panic in the surrounding area sources said.

Water pollution manifestations of an area source include:

Other area sources of air pollution are:

An "area source" is any stationary source that is not a major source.

It addresses criteria pollutants and toxic pollutants from both stationary and area sources.

Area sources are sources of pollution which emit a substance or radiation from a specified area.

Light now came from whatever direction none of them happened to be looking, and much more brightly, since the area source of illumination was much reduced.

Glass Manufacturing (area sources)

For example, area sources of air pollution are air pollutant emission sources which operate within a certain locale.

Types of air pollution sources which have finite extent are line sources, area sources and volume sources.

The U.S. Environmental Protection Agency has categorized 70 different categories of air pollution area source.

Initial input to receiving waters may arise from a point source discharge or a line source or area source, such as surface runoff.

In the case of the large number of small emission sources, emission inventories frequently have to resort to treating them collectively as area sources.
