| 摘 要： | 饮水水源水质的人体健康安全是水源是否安全的首要问题。在调查锡矿矿坑水作为个旧市A镇及B矿段锡矿生活区饮用水源情况的基础上,应用国际辐射防护委员会和美国环保署推荐的风险评估模型,开展饮用水的人体健康风险评价。结果表明,水源中重金属致癌物质所引起的健康危害较高,风险值超过了国际辐射防护委员会推荐的最大可接受风险水平,其中以Cr6+和As的致癌风险最大,应优先控制;非致癌物质所引起的健康风险较小,风险值在10-8以下,远低于推荐的最大可接受风险水平。虽然水中重金属含量符合相关标准要求,但是长期饮用对人体存在健康风险。

| Abstract: | Drinking water quality for human health safety is the primary problem of water sources. Analysis and evaluation in this aspect were conducted on the basis of investigation of a tin pit water which serves as drinking water source of town A in Gejiu City and ore block B. Human health risk assessment of drinking water was carried out with the risk assessment model recommended by the International Radiation Protection Committee and the US Environmental Protection Agency. The results show that health hazards of carcinogenic material caused by heavy metals in water are high, and the risk value exceeds the maximum acceptable level of risk recommended by the International Commission on Radiological Protection. Sexavalence chromium and arsenic are maximum carcinogenic risk substances and hence should be preferentially controlled. The health risk caused by the non-carcinogenic matter is relatively insignificant. The values below 10-8 are by far lower than the recommended maximum acceptable risk level. Although the heavy metal content in water meets the requirements of relevant standards, there still exists human health risk if such water is drunk for a very long time. |
