Potential Ecological Risk Assessment and Disposal of Heavy Metal Pollution in Sediment of Qianshan River(Zhuhai Section)
This paper analyzes the content of heavy metals,such as cadmium,mercury,arsenic,lead,chromium,copper,zinc,nickel,etc.in the sediment of Qianshan River(Zhuhai section)and its tributaries.The potential ecological hazard index method is used to determine the potential ecological risk of heavy metals in the sediment.This study proposes suggestions for sediment treatment and utilization.The evaluation results indicate that Qianshan River(Zhuhai section)and its main tributaries have a low potential ecological risks of heavy metal pollutants.In individual samples,the potential ecological risk coefficients of single pollutants,such as total cadmium and total mercury,are assessed as medium or high risk.If dredging is carried out,the river sediment is not suitable for backfilling agricultural land.
