The contaminated soil by mining activities could be transported through the erosive effect of wind. In this study, human health risk was assessed for exposure to heavy metals (Cu, Zn, Cd, Pb) present in surface soil of Irankouh zinc–lead mine, (the nearest mine to Isfahan, Iran) as one of the main dust storm sources. The effect of improper mining waste and tailings management in the Irankouh zinc–lead mine was not deeply investigated. Thus, 65 surface soil samples were collected (mining and residential area) and subjected into chemical analyses, then various assessment approaches were conducted on the obtained data. It was found that the mean concentrations of Zn (1035.2 mg kg⁻¹, SD = 563.7), Cd (2.53 mg kg⁻¹, SD = 1.1), and Pb (281.7 mg kg⁻¹, SD = 115.6) were higher in the study area than in the Earth’s crust. Results of enrichment factor (EF) represented high enrichment with the mean values for Cd (5.75), Zn (7.29), and Pb (4.42) in the study area. The considerable ecological risk (RI = 497.95) and high contamination degree (mC_d = 11.83) obtained in this study implicated the potential of high health risk in the mining area. Moreover, the results of multivariate analysis techniques revealed a high interrelation between Pb, Zn, and Cd and their common anthropogenic origin in the residential area. All the calculated HI values were higher than one indicated probable adverse effect on human health due to the mining activities. In general, the proper waste management of Irankouh zinc–lead mine should be planned and performed to reduce its environmental adverse effects.

矿区表层土壤中重金属污染与人体健康风险评估的综合研究

采矿活动所污染的土壤可以通过风的侵蚀作用进行运输。在这项研究中，评估了人类健康风险，评估了作为主要沙尘暴之一的伊朗伊库兹锌铅矿（距伊朗伊斯法罕最近的矿山）表层土壤中存在的重金属（铜，锌，镉，铅）的健康风险。资料来源。没有对伊库尔锌铅矿中不当采矿废物和尾矿管理的影响进行深入研究。因此，收集了65个表层土壤样本（采矿和居民区）并进行了化学分析，然后对获得的数据进行了各种评估方法。发现锌（1035.2 mg kg ^-1，SD = 563.7），镉（2.53 mg kg ^-1，SD = 1.1）和铅（281.7 mg kg ^-1）的平均浓度，SD = 115.6）在研究区域要比地壳高。富集因子（EF）的结果代表了高富集，研究区域中的Cd（5.75），Zn（7.29）和Pb（4.42）的平均值。相当大的生态风险（RI = 497.95）和高污染度（mC _d 在这项研究中获得的= 11.83）暗示了矿区高健康风险的潜力。此外，多变量分析技术的结果表明，铅，锌和镉与居民区常见的人为起源之间存在高度相关性。所有计算得出的HI值均高于一个表明的开采活动可能对人体健康造成的不利影响。总的来说，应计划并执行对伊朗库锌铅矿的适当废物管理，以减少其对环境的不利影响。
