摘要
Abstract
Sediment pollution is a worldwide environmental problem.In order to study the ecological risk of heavy metals in the sediment of aquaculture water and its phytoremediation,we measured the content of Cr,Cu,Zn,As, Cd,and Pb in the sediment,and assessed the potential ecological risk of heavy metals in the sediment using the Hakanson’s method of potential ecological risk factors.We also studied the accumulative ability of winter wheat.Our study shows that Cd has the highest ecological risk in the sediment,while the potential ecological risk of other heavy metals is low.The overall potential ecological risk of these six heavy metals used in present study,as compared to various kinds of reference materials,is slight or moderate.In addition,the content of Cr and As in crab found high, and could be removed by winter wheat effectively.关键词
