摘　　要：连续采集2021年1—10月长江镇江段饮用水4个取水口的表层水样,探讨水样中12种重金属(Mn、Zn、As、Cr6+、Ni、Cu、Pb、Sb、Se、Cd、Hg、Fe)浓度的分布特征,并通过EPA健康风险评价模型进行健康危害风险进行评估。结果表明,长江镇江段饮用水体中12种重金属的平均浓度均达到GB 3838—2002中规定的Ⅰ类水质指标。流域内不同区域人群产生的总非致癌和总致癌健康风险分别为2.59×10^(-9)~3.08×10^(-9)和1.12×10^(-6)~1.32×10^(-6),流域内健康风险均在接受水平。Surface water samples from four drinking water intakes in Zhenjiang section of the Yangtze River from January to October in 2021 are collected.Exploring the distribution characteristics of 12 heavy metal concentrations(Mn,Zn,As,Cr^(6+),Ni,Cu,Pb,Sb,Se,Cd,Hg,Fe)in water samples and assessing health hazard risks through EPA health risk assessment model.The results show that the average concentration of 12 heavy metals in drinking water in Zhenjiang section of the Yangtze River reached the classⅠwater quality index stipulated in GB 3838—2002.The total non carcinogenic and total carcinogenic health risks generated by people in different regions of the basin are 2.59×10^(-9)~3.08×10^(-9)and 1.12×10^(-6)~1.32×10^(-6),indicating that the health risks in the basin are acceptable.
