摘    要:对南柳河排污口邻近海域表层沉积物中重金属的含量分布、富集状况进行分析,并采用潜在生态危害指数法进行评价。结果表明:Cu,Pb,Zn,Cd,Hg含量分布呈现由西北到东南递减的变化特点;5种重金属元素的富集程度均较重,且程度由大到小依次为Pb>Zn>Cu>Hg>Cd;生态危害评价显示,Pb,Cu,Zn等元素属于轻微生态危害,Hg,Cd等元素属于中等生态危害,5种元素生态危害程度由重到轻依次为Hg>Cd>Pb>Cu>Zn。

关 键 词:重金属  沉积物  排污口  评价

Abstract:This paper dealt with the distribution and enrichment of heavy metals in surface sediments from the sea area of Nanliuhe terrestrial pollution source, and the method of potential ecological risk index was used to assess the heavy metals. The results showed that the contents of Cu, Pb, Zn, Cd and Hg appear gradually degressive from northwest to southeast; the enrichment of 5 kinds of heavy metals appears higher, and the order of enrichment degree is Pb > Zn > Cu > Hg > Cd; the assessment results revealed that Pb, Cu and Zn belong to the light potential ecological risk, Hg and Cd belong to the middle potential ecological risk, and the order of pollution degree is Hg > Cd > Pb > Cu > Zn.
Keywords:heavy metals  sediments  terrestrial pollution source  assessment
