Abstract：Based on the survey data of the surface sediments in the Jitimen estuarine of Pearl River in June 2012,the heavy metals Hg,As,Cu,Pb,Cd,Zn,Cr,and grain-sizer were analyzed.Sandy sedi-ments is the main constituent,it is less likely to accumulate pollutants,so it has lower heavy metal con-tents than the local background values and adj acent areas averages.Evaluated through standard index, potential ecological risk index and geo-accumulation index,the sediments environment is safe,low pol-lution and low ecological hazard.The conclusions may be slightly different because of the evaluation methods and involved factors various,but overall,the evaluation index of As and Cd is higher than the other factors,while the evaluation index of Cr is lower.The above description of As and Cd exists in potential pollution or ecological risk.
