摘　　要：统计2022年长沙万人以下农村供水工程出厂水中的亚氯酸盐含量,对其超标风险进行评估,并使用EPA的健康风险模型对亚氯酸盐经口暴露健康风险进行评价。结果表明,2022年长沙万人以下农村供水工程亚氯酸盐指标检出率为47.8%,合格率为98.6%,整体较好,但存在少量亚氯酸盐超标情况。长沙农村地区的亚氯酸盐对人类造成非致癌健康风险的最大值为4.11(成年男性)、4.27(成年女性)、4.15(成年平均),成年人危险指数平均值为0.17,它对不同性别人群的健康危害差异不显著。整个研究区域中,4.4%的水样中亚氯酸盐非致癌风险高于推荐的风险参考水平。By conducting statistical analysis of the chlorite content in the effluent of rural water supply projects with a population of less than 10000 in Changsha in 2022,the risk of exceeding the standard was evaluated,and the health risk of oral exposure to chlorite was assessed using the EPA’s health risk model.The results showed that in 2022,the detection rate of chlorite in rural water supply projects with a population of less than 10000 in Changsha was 47.8%,and the pass rate was 98.6%,which was generally good,however,there were a few chlorite projects that exceeded the standard.The maximum non-carcinogenic health risks caused by chlorite in rural areas of Changsha to humans were 4.11(adult males),4.27(adult females),and 4.15(adult average),with an average value of adults was 0.17,which showed that there was no significant difference in its health hazards between genders.In the entire study area,4.4%of water samples showed that the non-carcinogenic risk of chlorite is higher than the recommended risk reference level.
