Integrated pollutant concentration distribution over area surrounding elevated point source

Summary Air pollutant dispersion from a continuous elevated point source in the atmosphere for a combination of varying meteorological parameters is studied in the frame of a Gaussian plume model. The Gaussian basic formula for the concentration is reformulated in polar coordinates. The study derives a general formula for the annual or seasonal integrated concentration over sixteen angular sectors surrounding the source. A computer program is developed to determine the frequency occurrence of the wind velocity and direction together with the stability classes in order to evaluate the integrated pollutant concentration as a function of the distance from the source in the different angular sectors. The results have been applied to the area surrounding the reactor of the Nuclear Research Center at Inshas-Egypt.With 2 Figures
