Abstract :

The purpose of this study is to evaluate the pollutant distribution of suspended particles with a diameter of less than 2.5 microns in sports spaces in Tehran. This research is practical in terms of output. At first, relevant data were collected and analyzed through pollutant measurement stations in the area. It was classified based on Kriging interpolation. Finally, based on the air quality index table, the importance level of health safety was classified and the corresponding map was prepared. Through the IO technique, the location layer of sensitive and vulnerable uses was placed on the surface of the area and the pollutant layer. The results showed that district 10 of Tehran municipality with an average concentration of 42 micrograms per cubic meter is the most polluted area in terms of this pollutant in Tehran. also; The highest amount of PM2.5 pollutant is related to the central and southern half of the region. also; The most polluted month of the year was November with an average concentration of 56 micrograms per cubic meter. This area has had 104 unhealthy days for sensitive groups in terms of air quality index based on the type of pollutants. The environmental and health risk assessment for this pollutant indicates that according to the William Fine method, risk number 105 has been determined, which represents the average level of risk. therefore; It requires corrective and emergency measures to control the risk.
