As an air pollutant is transported, the pollutant disperses into the surrounding air so that it arrives at a lower concentration than it was on leaving the source. Strict environmental regulations worldwide resulted in a growing concern about the validity of air quality dispersion models. The present work is a try to evaluate the applicability of some dispersion models on the emission from an industrial source. The results obtained suggest that the Classical Gaussian Plume model is reliable and applicable far from the source (5000 m and beyond); while PRISE model is applicable in the close region (within a few hundred meters) from the source.
