    铜制储水容器的健康风险评价

    Health Risk Assessment on Copper Containers Used for Drinking Water Reservation

      摘要
    • 摘要:
      目的 评价铜制储水容器金属离子溶出对人体的健康风险, 为安全使用铜制储水容器提供科学依据。
      方法 随机抽取两种市售铜制储水容器, 监测铜制储水容器饮用水中金属离子浓度, 参照美国环保署的水质健康风险评价模型进行初步评价。
      结果 黄铜和红铜两种铜制储水容器金属离子溶出所引起的健康危害个人年风险水平分别为1.37×10-5/年、3.41×10-7/年, 均低于国际辐射防护委员会(ICRP)推荐的最大可接受风险水平5.0×10-5/年。致癌物Cd是两种铜制储水容器的最大风险源, 风险水平分别占99.9%和79.5%, 应该作为风险管理的重点对象。
      结论 铜制储水容器的健康风险水平低于ICRP推荐的最大可接受风险水平, 采用铜制容器储备饮用水能够满足人体对饮水的安全性要求。

       

      Abstract:
      Objectives To assess the health risk of metal ions in drinking water reserved in copper containers and to provide some scientific evidences for the safe use of copper containers.
      Methods The concentration of metal ions in the water reserved in copper containers was monitored; the container were purchased from markets by random. The health risk assessment was carried out by referring to the U.S.EPA health risk assessment model.
      Results The annual risk levels of personal health hazards for metal ions in brass and copper containers were 1.37×10-5/y and 3.41×10-7/y, respectively, which were lower than the maximum allowance levels recommended by the International Commission on Radiological Protection (ICRP). The biggest risk of copper containers was carcinogen cadmium, which accounted for 99.9% and 79.5% of risks, respectively. More attentions should be paid to cadmium in the coming risk assessment.
      Conclusions The health risk of storing drinking water in copper container was lower than the maximum allowance level recommended by ICRP, which demonstrated that using copper containers for reserving drinking water was safe.
