摘要: 鄱阳湖是我国最大的淡水湖及重要生态经济区，选取鄱阳湖东南部地下水有机物进行检测分析并对其进行风险评价。结果表明：定性共鉴定出4类32种有机物；检出率超过50%的有机物共10种，其中80%的有机物检出率达到了100%；定量出的有机物中邻二甲苯质量浓度平均值最高，为2.33 μg·L^-1，滴滴涕的质量浓度平均值最低，为0.02 μg·L^-1，暗示研究区地下水已受到了有机物的污染。健康风险评价表明，研究区地下水中的有机物不会对人体健康产生致癌与非致癌风险；但有机物具有长期残留性及慢性毒性等特征，探究鄱阳湖区域地下水有机物的污染源及有机物的降解工作仍需进行。

Abstract: Poyang Lake is the largest freshwater lake and it is an important ecological economic zone in China. The monitoring analysis and risk assessment of groundwater in the southeast of Poyang Lake were investigated in this paper. The results showed that 32 kinds of organic compounds in 4 categories were qualitatively identified. The detection rates of 10 kinds of organic substances were over 50% in the monitoring analysis results, of which the detection rates of 8 kinds of organic substances were over 100%. The average mass concentration of o-xylene is the highest (2.33 μg·L^-1), and the DDT concentration as the lowest is 0.02 μg·L^-1, which indicated the groundwater of Poyang Lake has been polluted by organic pollutants. Moreover, the results of risk assessment show that the organic pollutants in the groundwater of Poyang Lake will not pose cancer nor non-cancer risk to human health. However, it is still necessary to monitor the pollution source and to remove the organic pollutants in groundwater of Poyang Lake because of the persistence and chronic toxicity of of the organic pollutants.
