Evaluation of Air pollutant Concentration from Continuous and Instantaneous Sources

In this work. dispersion studies carried out in unstable conditions, and the observed concentrations were statistically evaluated with predicted concentrations using Gaussian plume model. The Gaussian plume model is used as semi-analytical solution of the molecular diffusion equation for respect to instantaneous and continuous point, line and area sources. Results show that the applied mathematical model is suitable and applicable as the predicted concentrations were in good agreement with the observed concentrations of I ¹³⁵ in all cases.
