摘　　要：结合人体血汞浓度分布和最高无影响作用浓度(NOAEL)分布,以汞暴露量超过NOAEL的概率为评价指标,计算了中国部分地区汞引起的儿童健康风险.研究表明,中国大部分地区风险较低,超过NOAEL的概率为10-7～10-5;而在受到污染的第二松花江流域的松原和长春风险较高,分别为2.24×10-3和3.30×10-5;贵州汞矿区附近的儿童也面临着很高的汞暴露风险,最高达到6.87×10-3.中国儿童汞健康风险呈现明显的区域性特征.Due to the domestic situation of China, the researches on health risk of mercury were limited. In this study, health risk of mercury for children in China （some regions） were assessed by intergrating the probabilities of both blood mercury and no observed adverse effect levels（NOAEL） in some parts of China. The health risk in most parts of China was in the range of 10^-7 to 10^-5, the risk in Songyuan and Changchun located at Dier Songhuajiang River basin were 2.24×10^-3 and 3.30×10^-5, respectively. Especially, residents in Guizhou mining areas were faced to risk as high as 6.87×10^-3. The health risk of mercury showed a regional characteristics.
