| Abstract: | In order to figure out heavy metal pollution in the surface sea sediments of the Changli Gold Coast Reserve,the chemical speciation of heavy metals(Cr,Pb,Cu,Zn and Ni)in the surface sea sediments was determined by using the latest version of the 3-step sequential extraction procedure recommended by European Community Bureau of Reference(BCR).The ecological risk of heavy metals was assessed by adopting the ratio of secondary phase to primary one and the potential ecological hazard index method.The results indicated that the content of the above five heavy metals exceed background value in China.All of these five metals existed mainly in the form of residual.In the secondary phase,Cu and Ni were mainly composed with oxidizable faction,while other elements were mainly distributed in reducible faction.RSP results showed that in the surface sea sediments Pb and Ni were the primary elements with high ecological risk while Cu,Cr and Zn were with relatively slight risk.According to the comprehensive assessment results obtained after using the potential ecological hazard index method,the five metals’ecological risk degree can be sequenced as Ni>Pb>Cu>Cr>Zn. |
