通过对近年来有关淮河流域重金属污染文献分析研究,系统地总结了该流域沉积物中重金属类环境激素Cd、Pb含量在空间分布特点,干流流经城市河段、各支及洪泽湖区沉积物中Cd和Pb的含量明显高于干流其他区域。利用潜在生态风险指数法对淮河流域沉积物中重金属类环境激素Cd和Pb进行分析和评价,得出淮河流域支流和洪泽湖区沉积物中的重金属类环境激素Cd和Pb污染程度和生态危害程度显著高于淮河干流沉积物中的Cd和Pb。
通過對近年來有關淮河流域重金屬汙染文獻分析研究,繫統地總結瞭該流域沉積物中重金屬類環境激素Cd、Pb含量在空間分佈特點,榦流流經城市河段、各支及洪澤湖區沉積物中Cd和Pb的含量明顯高于榦流其他區域。利用潛在生態風險指數法對淮河流域沉積物中重金屬類環境激素Cd和Pb進行分析和評價,得齣淮河流域支流和洪澤湖區沉積物中的重金屬類環境激素Cd和Pb汙染程度和生態危害程度顯著高于淮河榦流沉積物中的Cd和Pb。

Analyzing the literature on heavy metal pollution of the Huaihe River Basin in recent years.Systematically summed up the spatial distribution and content of the heavy metals environmental hormones Cd,Pb in sediments of the Huaihe river basin.The content of Cd,Pb in sediment of he reach which flows through the urban river,were significantly higher than other regions of the main stream,especially in sediment the anabranch and Hongze lake area.Using the index of potential ecological risk of heavy metals in sediments to analyze and evaluate the ecological risk assessment of environmental hormones Cd and Pb in Huaihe river basin.The environment hormone levels and the extent of ecological damage of the heavy metals Cd and Pb pollution in sediments was significantly higher than in the Huaihe River sediment Cd and Pb pollution and ecological damage degree.
