Why is there a need for air dispersion models?
The dispersion models are used to estimate the downwind ambient concentration of air pollutants or toxins emitted from sources such as industrial plants, vehicular traffic or accidental chemical releases. They are most useful for pollutants that are dispersed over large distances and that may react in the atmosphere.
