饮用水中重金属的暴露评估

目的：通过对饮用水中的重金属的暴露评估,为饮用水中化学物质的暴露评估提供方法参考。方法：运用@risk4.5软件建立膳食暴露模型,对饮用水中的8种重金属（锌、镍、锰、铁、砷、汞、铅、铬）进行概率暴露评估。结果：人群中所有人对饮用水中的镍、汞和铅的暴露水平都小于对应的ADI。铬、砷、锌、铁、锰的暴露水平大于对应ADI的人群比例分别是0.03%、0.17%、0.29%、0.37%、3.01%。结论：镍、汞和铅的暴露水平不会对成年人群造成健康风险。铬、砷、锌、铁、锰的暴露水平对很小一部分人群的健康造成风险。

Exposure assessment for heavy metals in drinking water

Object:To direct exposure assessment of chemicals in drinking water,a exposure assessment of heavy metals was conducted in drinking water.Method:a probabilistic risk assessment for eight heavy metals(zinc,nickel,manganese ferrum,arsenic,hydrargyrum,lead,chromium)was conducted and dietary exposure model was established by @Risk 4.5.Results:The chronic daily intake(CDI)of nickel,hydrargyrum and lead were bigger than the corresponding acceptable daily intake(ADI)for all the adults.The proportion of the CDI was...
