Abstract
Airport pollution from increased air traffic affects regional air quality and health negatively. Previous research has mainly focused on modeling pollutant distribution near the airport in a short radius. Also, limited studies have been performed to create a general model of pollutant distribution for the future planning of urban development in a wide radius. In this research, the amount of gaseous pollutants and suspended particulate matter (SPM) produced by Imam Khomeini International Airport (IKIA) was estimated. The modeling of the distribution of pollutants was performed using AERMOD and ISCST3 software in a 50 km radius, taking into account the main meteorological and atmospheric parameters. The pollutants selected in this study were gaseous pollutants, including nitrogen oxides (NOx), carbon monoxide (CO) and sulfur dioxide (SO2) estimated by the simple approach method (option A) presented by the International Aviation Organization (ICAO), as well as SPM estimated by FOA.3 method provided by the Department of Federal Organization. IKIA produced 596 tons of NOx, 344 tons of CO, 19 tons of SO2 and about 3 tons of SPM from March 2021 to February 2022. Also, the maximum concentrations were in the 1-h time frame, and the results showed that the concentration of NOx, CO, SO2 and SPM was 162, 93.4, 5.14, and 0.77 μg/m3, respectively. The prevailing winds of the airport from the west and northwest caused the maximum impact of pollutants' distribution on the residential and industrial areas located in the east and southeast of the airport. Also, due to the east and southeast winds, most of the development phases of the airport city, which are located in the west and northwest of the airport, were affected by the distribution of pollutants. This research developed a pollutant distribution model to gain insight into mitigating airport pollution's impact on residential, industrial, and airport areas.
