Abstract:
Particulate matter is an important source of air pollution. Particulate matters have an Undesirable effect on the environment, economic, and the health of Tehran Citizens. Annually, more than 8 thousands of tons of mineral dust from Internal and external resources deposit in Tehran city. In this project, the increase in the level of PM10 concentration during June, 12th to 14th, 2015 have been considered. The intrusion and dispersion of mineral dust during June, 11th to 15h, 2015 have been simulated with the HYSPLIT Model. Also, the Trajectory of particle end in Tehran during the mentioned days simulated and plotted with the HYSPLIT. The results show that more than 85% of PM10 reported by Air pollution monitoring stations in Tehran, originated from The Kavir desert and from the east and southeast neighbor states. All results have been validated quantitatively with PM10 concentration reported by Air pollution monitoring stations of Tehran Air Quality Control Company and qualitatively with Satellite RGB images and wind speed fields
