ABSTRACT
The atmosphere is unabatedly bombarded with numerous substances released from natural and anthropogenic sources. When these substances are in concentrations higher and duration longer than normal, they tend to cause injury to life or property or interfere with comfortable enjoyment of life or property, repose, health and safety, they tend to constitute pollutants. Their levels and lengths of exposure are determined by air quality impact assessment (AQIA). In this study, the air quality impact assessment procedure used are the mathematical models of plume dispersion(Gaussian profile), atmospheric, meteorological and topographical conditions to evaluate pollution sources and concentrations of non- reacting substances, and thermodynamics and reaction kinetics models for reacting substances . Knowledge and understanding of these models would help in predicting concentrations of air pollutants in the atmosphere, and provide a picture of possible damage to vegetation, organisms and the environment, with a view to arriving at solutions for reduction if not complete elimination of pollutants in the atmosphere, and prevent disastrous consequences of pollutants from newly planned industries.
Key words: Mathematical models, prediction, reacting, non-reacting and substances.
