چکیده مقاله:
Air pollution is the most important issue in industrial and large cities. Arak city has a very complicated situation as it is mountainous, its industries are near the city and its urban causes traffic load. In this study air pollution has been modeled to find how NOx changes in Arak & Mohajeran cities annually. In this research, all of the important industrial factory (Power plant, Vagon pars Co, Mashin Sazi Co, Azarab Co, refinery, petrochemical factory) and dynamic source (vehicle, truck...) has been included to show their effect and to find the appropriate control strategy. AERMOD software has been applied to model in which synoptic data, upper data, topography maps and dynamic vehicle source is used. The area is assumed 50km × 30 km., reference point is (353076.27, 3758168.73) in zone 39. Finally, against common opinion, investigation yielded that the biggest source of pollution in Arak is dynamic source (vehicle, bus…) which is approximately about 90% in arak and the companies have their own 10 %.
