Abstract :

Air pollution, a complex and multidimensional phenomenon, has increasingly affected industrial and urban communities. Particulate matter (PM), as a primary air pollutant, significantly affect quality of life in urban areas. These particles, due to their ability to penetrate deep into the lungs and enter the bloodstream, are responsible for numerous acute and chronic respiratory and cardiovascular diseases. The aim of this research is to model the dispersion of air pollutants resulting from the construction and operation of the proposed project. In this study, the AERMOD software was used to model air pollutants. This software evaluates and quantifies the level of air pollution related to pollutants at a specific location using meteorological data, a digital elevation model, and information related to pollution sources. The results of the dispersion modeling of pollutants showed a maximum concentration of PM10 of 47.9 micrograms per cubic meter, which was lower than the maximum 24-hour standard. Therefore, the proposed project, in terms of the maximum 24-hour concentration of suspended particles, excluding the background, is below the standard limit and does not pose a threat to air quality.
