摘　　要：为分析鄱阳湖周边水体重金属污染特征及人体健康风险,于鄱阳湖周边采集18个地表水水样,对水体中重金属的来源及分布进行分析,并根据美国环保局(USEPA)的风险评价模型评价水体中重金属对人体的健康风险。研究区水体主要阳离子为Ca^(2+),阴离子为HCO_(3)^(-)、SO_(4)^(2-)与Cl^(-)。水化学成因主要为岩石风化及矿物水解,部分受大气降水作用控制。地表水中重金属元素平均浓度为Fe>Ba>Mn>Mo>Zn>Cu>Ni>Pb。Fe、Mo、Ni、Mn均有不同程度的超标现象,其主要来源于肥料施放、工厂排放等活动。Mo对儿童和成人的HQ der、HI>1,Ba对儿童的HQ der、HI>1,对人体健康会造成较大危害。研究可为鄱阳湖周边水资源保护提供科学依据。In order to analyze the pollution characteristics and human health risks of heavy metals in water around Poyang Lake,18 surface water samples were collected around Poyang Lake.The sources and distribution of heavy metals in water were analyzed,and the health risks of heavy metals in water were evaluated according to the risk assessment model of the United States Environmental Protection Agency(USEPA).The main cations of the water in the study area are Ca^(2+),and the anions are HCO_(3)^(-),SO_(4)^(2-)and Cl^(-).The hydrochemical genesis is mainly rock weathering and mineral hydrolysis,which is partly controlled by atmospheric precipitation.The average concentration of heavy metal elements in surface water is Fe>Ba>Mn>Mo>Zn>Cu>Ni>Pb.Fe,Mo,Ni and Mn have different degrees of exceeding the standard,which mainly comes from fertilizer application,factory emissions and other activities.The HQ der and HI>1 of Mo for children and adults,and the HQ der and HI>1 of Ba for children,it will causes great harm to human health.The study provides a scientific basis for the protection of water resources around Poyang Lake.
