Geochemical and hydrogeochemical studies were conducted to assess the origin and geochemical mechanisms driving lead enrichment in groundwaters of semi-arid regions in Central Iran. In this study, 149 water samples were analyzed using inductively coupled plasma mass spectrometry (ICP-MS). Concentrations of Pb and As in about 68% and 27% of the samples, respectively, exceeded WHO guidelines. Analyzing the results of ICP-MS of parental rocks and aquifer sediments shows that unweathered volcanic rocks were the primary source for lead mobilizing to groundwaters.
开展了地球化学和水文地球化学研究，以评估伊朗中部半干旱地区地下水中铅富集的来源和地球化学机制。在本研究中，使用电感耦合等离子体质谱仪（ICP-MS）对149个水样进行了分析。分别约68%和27%的样品中铅和砷的浓度超过了世界卫生组织的指导标准。对母岩和含水层沉积物的ICP-MS结果分析表明，未风化的火山岩是铅迁移到地下水中的主要来源。
