The aim of this study was an integrative assessment of heavy metals associated with urban dust data in Iran (Ahvaz, Isfahan, and Shiraz). Samples of urban dust from four sites (traffic, industrial, residential, and Greenland) were collected, and ten heavy metal concentrations were determined using ICP_MS in each sample. The highest average concentrations of metals were at the traffic site for the Mn, Zn, and Cr metals. The PMF model indicates a higher percentage of Pb participation, which shows the importance of traffic resources. The highest non-carcinogenic risk (HI) was for the Cr and the carcinogenic risk was tolerable. To evaluate aerosol and its effects on urban dust, Aerosol Optical Depth (AOD) data were used during 2003-2023. According to the Mankendall test, the trend of AOD has been increasing in Esfahan (p_value < 0.05) and Shiraz. Although Ahvaz's AOD is about two times greater than other cities, the aerosol trend in Ahvaz is decreasing.
本研究旨在综合评估伊朗（阿瓦士、伊斯法罕和设拉子）城市灰尘数据中与重金属相关的内容。从四个地点（交通、工业、住宅和格陵兰）采集城市灰尘样本，并使用 ICP-MS 在每个样本中测定十种重金属浓度。在交通地点，Mn、Zn 和 Cr 金属的浓度最高。PMF 模型表明 Pb 的参与比例较高，这表明交通资源的重要性。Cr 的非致癌风险（HI）最高，致癌风险可接受。为了评估气溶胶及其对城市灰尘的影响，在 2003-2023 年期间使用了气溶胶光学深度（AOD）数据。根据 Mankendall 检验，伊斯法罕（p 值<0.05）和设拉子的 AOD 趋势呈上升趋势。尽管阿瓦士的 AOD 是其他城市的两倍左右，但阿瓦士的气溶胶趋势正在下降。
