摘要

本研究评估了从巴基斯坦前联邦直辖地区的七个部落地区(巴焦尔、莫赫曼德、开伯尔、奥拉克扎伊、库拉姆、南瓦济里斯坦和北瓦济里斯坦)采集的七个水样中的六种重金属锌(Zn)、铁(Fe)、铜(Cu)、镍(Ni)、铬(Cr)和镉(Cd)。所有样品均采用湿消解法进行消解,消解后的样品采用原子吸收分光光度计进行重金属分析。来自七个地区的水样结果与世界卫生组织和环境保护署的推荐标准值进行了比较。镍(Ni)的分析结果显示,开伯尔地区的水的浓度最高(0.093 mg/l),而南奥拉克扎伊地区的水的浓度最低(0.011 mg/l)。铁(Fe)在奥拉克扎伊地区水体中浓度最高,为0.32 mg/l。铬(Cr)的最高浓度为0.19 mg/L。此外,结果表明,锌(Zn)浓度最高的是奥拉克扎伊县(0.87 mg/l),铜(Cu)浓度最高的是开伯尔县(1.92 mg/l)和莫赫曼德县(1.92 mg/l),镉(Cd)浓度最高的是奥拉克扎伊县(0.0029 mg/l)。因此,通过与世界卫生组织和环境保护局标准值的比较,本研究表明,所有部落地区的水都是安全的饮用水

Evaluation of Heavy Metals in Drinking Water of Tribal Districts Ex-FATA Pakistan
This study was conducted to evaluate the six heavy metals zinc (Zn), iron (Fe), copper (Cu), nickel (Ni), chromium (Cr), and cadmium (Cd) in seven water samples collected from seven tribal districts (Bajaur, Mohmand, Khyber, Orakzai, Kurram, South Waziristan and North Waziristan) from Ex-FATA Pakistan. All samples were digested using the wet digestion method and the digested samples were analyzed for heavy metals using an atomic absorption spectrophotometer. Results from water samples from seven districts were compared to the recommended standard value from the World Health Organization and the Environmental Protection Agency. The results obtained from the analysis for nickel (Ni) showed that the highest concentration (0.093 mg/l) was reported in the water of Khyber district, while the lowest concentration (0.011 mg/l) was found in the water of South Orakzai district. Iron (Fe) had the highest concentration (0.32 mg/l) in the water of Orakzai district. The highest concentration (0.19 mg/L) of chromium (Cr) was reported in the water of Orakzai district. In addition, the result showed that the highest concentration (0.87 mg/l) of zinc (Zn) was in Orakzai district, the highest concentration (1.92 mg/l) of copper (Cu) in Khyber and Mohmand districts ( 1.92 mg/l), while the highest concentration (0.0029 mg/l) of cadmium (Cd) was measured in the water of Orakzai district. Therefore, based on comparison to WHO and EPA standard values, this study shows that the water of all tribal districts is safe for drinking water purposes
