| Abstract: | The contents of Cu,Pb,Zn,Cd in the 40 surface sediments samples from Tajiaozhou wetland of Minjiang estuary were determined.The results indicated that the contents of Cu,Pb,Zn,Cd ranged from 4.13-42.62,40.31-104.63,50.36-516.39,0.14-1.39 mg·kg-1,respectively.The order of average content was: Zn>Pb>Cu>Cd.Compared with other estuary wetland of home and abroad,the average contents of Cu,Cd in Tajiaozhou wetland were relatively lower,but Pb,Zn was higher.According to the index of geoaccumulation,the pollution of Tajiaozhou wetland mainly came from Cd and Zn.The order of polluting degree was Cd>Zn>Pb>Cu.The assessment result of the potential ecological risk showed that average Hakanson′s potential ecological risk index(RI) of this area was 315.7±156.4,which belongs to strong risk level.Analyzed from the samples,the potential ecological risk was mainly resulted from Cd and Pb,Cu,Zn belongs to light potential ecological risk. |
