摘要
利用电感耦合等离子体质谱仪(ICP-MS)对锦州湾表层沉积物中6种重金属元素(Cd、Zn、Cu、Cr、Pb、As)总量进行分析测定,并运用潜在生态风险指数Hakanson评价方法对锦州湾表层沉积物重金属污染状况进行评价,结果表明:锦州湾表层沉积物中Zn、As、Cd和Pb等重金属元素已经达到了极重的污染水平,并使得锦州湾海域部分区域长期处于高生态风险等级。
The contents of 6 heavy metal elements in sediments in Jinzhou Bay were analyzed by a mass spectrometry with inductive coupled plasma(ICP-MS).The potential ecological risk index(Hkanson) was employed for the assessment of the sediment quality.The results showed that the pollution of Zn,As,Cd and Pb was very serious in the surface sediments,and the potential ecological risk of trace metals was very high in Jinzhou Bay.
