摘　　要：对“十三五”期间湘江衡阳段水环境健康风险进行评价及趋势分析。“十三五”期间,各个断面各年度的总健康风险在8.9×10^(-6)~8.1×10^(-5) a^(-1),松柏、新塘铺、城北水厂3个断面各年度的总健康风险略超过国际辐射防护委员会(ICRP)推荐值5×10^(-5) a^(-1)、属于中等风险,归阳镇、熬洲、朱亭断面3个断面各年度低于ICRP推荐值、为低风险;“十三五”期间各断面水质总健康风险略呈下降趋势或基本保持稳定。湘江衡阳段水环境健康风险主要受化学致癌物砷的影响,化学致癌物健康风险远高于非致癌物。The water environmental health risk assessment and trend analysis of Hengyang section of Xiangjiang River during the 13th Five Year Plan period were carried out.During the 13th Five Year Plan period,the total health risk of each section in each year ranged from 8.9×10^(-6)to 8.1×10^(-5) a^(-1).The total health risk of Songbai,Xintangpu and Chengbei waterworks in each year was slightly higher than the ICRP recommended value of 5×10^(-5) a^(-1),which belonged to medium risk.The three sections of Guiyang town,Aozhou and Zhuting in each year were lower than the ICRP recommended value,which belonged to low risk During the third five year plan period,the total health risk of water quality in each section showed a slight downward trend or basically remained stable.The health risk of water environment in Hengyang section of Xiangjiang River is mainly affected by chemical carcinogen arsenic,and the health risk of chemical carcinogen is much higher than that of non carcinogen.
