Simulation of Pollution Distribution around the Tabriz Oil Refining Company by using ISCST Model

Air pollutants are potentially hazardous to human health, plants, animals, materials and surrounding environment including building, roads, etc. Almost in all cases, it is the human activities that are the main sources of pollution. Air pollution modelling is an essential tool for air pollution studies. Considering that observations are often sparse, models can be used to make inferences on concentrations where there is no information [1, 2]. The current study aimed to consider the pollutants (CO and SO2) concentration in areas adjacent to Tabriz Oil Refining Company and comparison of concentration with clean air standards of Environmental Organization of Iran. The effect of wind speed and direction on dispersion profile of air pollution was also considered. Therefore, the ISCST (Industrial Source Complex-Short Term) model was used to simulate pollutant distributions on two different days in order to assess the ground level concentration of pollutant in the study area.
