Steel and rolling industry are the most important industries polluting the environment. Therefore, aim of this study is to make an emission model for SO₂ and NO₂ pollutants released from the rolling industry of Sepid-Farab Kavir Steel (SKS) complex using the AERMOD model and health risk assessment. Sampling pollutants released from SKS complex was performed in January 2017 at 10 different sites. Distribution of these pollutants was investigated by AERMOD model, domain site of AERMOD was designed for area around the factory with a radius of 30 km, and also SO₂ and NO₂ modeling was performed for both natural gas and liquid fuel. Human health risk assessment was also studied. The results of this study demonstrated the emission of SO₂ and NO₂ from this complex is less than the maximum allowable, when used natural gas as the main fuel. The hourly concentration of SO₂ reached about 324 μg/m³, which in higher than the standard value for 1 h. Considering the findings, the urban gas is considered as a clean source in terms of furnace air output and the concentration of emitted pollutants. Also, it has no side effects on workers’ health.

钢铁和轧钢行业是污染环境的最重要行业。因此，本研究的目的是利用 AERMOD 模型和健康风险评估，建立 Sepid-Farab Kavir 钢铁 (SKS) 联合体轧制行业排放的 SO ₂和 NO _{2污染物的排放模型。}2017 年 1 月，在 10 个不同地点对 SKS 综合体释放的污染物进行了采样。采用AERMOD模型研究了这些污染物的分布，AERMOD的域站点设计为工厂周边半径30公里的区域，并对天然气和液体燃料的SO ₂和NO _{2进行了建模。}还研究了人类健康风险评估。这项研究的结果证明了 SO 的排放_{当使用天然气作为主要燃料时，该复合物的2}和 NO ₂小于最大允许值。_{SO 2}每小时浓度达到约324 μg/m ³，高于标准值1 h。考虑到研究结果，就炉膛空气输出量和排放污染物浓度而言，城市燃气被认为是一种清洁来源。此外，它对工人的健康没有副作用。
