Pollution is the most predominate cause that is effecting every living and nonliving organismson earth. While the main reason behind this is man activities for his existence, comforts and needs. Due to these a wide range of pollutants are being evaluated daily in to the atmosphere, in order to prevent pollution and to study the effect of those, several theory’s and strategies are evolved which can give use virtual results according to the date given with predefine conditions and limitations which are included in them. By using these models we can know the minimum effluent concentration that can be discharge into atmosphere and we can able to take the preventive measure. Abundantly used models are Box Model, Gaussian Model, Eulerian Model, Lagrangian Model, CFD Model and Dense Gas Model. Every model is briefly described and discussed its own postulates and drawback which are being discussed here, while they can’t predict the environmental impacts accurately.
