| 摘 要： | 分析鄱阳湖流域五大支流不同河段以及湖区水体中Pb、Cu、Zn和Cd浓度,结果表明鄱阳湖流域水体中重金属含量符合国家水质标准的要求。应用健康风险评价模型评价经饮水途径所致的健康风险,表明重金属Cd是产生风险的主要污染物;总健康风险主要集中在10-7~10-6a-1,最大值出现在信江下游,未超过国际辐射防护委员会（ICRP）推荐的通过饮水途径最大可接受风险水平;除赣江外,各河流中下游的总健康风险水平明显高于上游,赣江上游、信江中下游、乐安江中下游及饶河河段的总健康风险相对于其他区域明显偏高。

| Abstract: | The concentrations of Pb,Cu,Zn and Cd in water samples from different sampling points of Poyang Lake Basins and its five tributaries were determined.The health risk assessment of the watersheds water environment,which was based on heavy metal,was studied by the means of the Health Risk Assessment Model recommended by USEPA.The results showed that the concentrations of the heavy metal elements in Poyang Lake Basins met stated water quality standards.With regards to the drinking water,the health risk was caus... |
