Distribution Characteristics and Ecological Risk Assessment of Surface Sediment Pollutants in Jitimen Waterway
摘要
Abstract
In order to investigate the degree of sediment pollution and potential ecological risks in the Jitimen Waterway,the surface sediment pollutant content was sampled and monitored,and single factor pollution index method,land accumulation index method,and potential ecological risk index method were used for analysis and evaluation.The monitoring results show that the surface sediment pollutants of zinc,chromium,copper,lead,sulfide,arsenic,cadmium,and mercury in the Jiti Men waterway decrease in order,with concentrations of 137mg/kg,79.8mg/kg,49.0mg/kg,40.1mg/kg,17.5mg/kg,16.8mg/kg,0.74mg/kg,and 0.174mg/kg,respectively.There is a certain spatial difference in their levels.The overall pollution level of heavy metal sediment pollutants in the Jitimen Waterway is relatively low,with cadmium being at a moderate level of pollution and most other heavy metals remaining at an uncontaminated level.The comprehensive potential ecological risk index of heavy metal sediment pollutants in the Jitimen Waterway is between 99.71 and 212.04,overall at a moderate ecological risk level.Among them,the potential ecological risk indices of cadmium and mercury are relatively high.关键词
