摘　　要：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。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 higher than that of the ADI,with the amount of chromium,arsenic,zinc,ferrum and hydrargyrum reaching 0.03%,0.17%,0.29%,0.37%,3.01% respectively.Conclusion：There were no risk of nickel,hydrargyrum,lead for adults at this exposure.Exposures of chromium,arsenic,zinc,ferrum,hydrargyrum were not acceptable for a small proportion of adults.
