河湖底泥污染评价方法研究综述

Research on Assessment Method of Sediment Pollution in River and Lake

水体底泥污染是城市水环境恶化的主要原因之一,底泥污染评价对于选用原位处理或异位处理方式具有重要指导意义。分别对重金属、有机质以及多环芳烃3种物质的污染评价方法进行探讨和总结,并基于茅洲河柱状样数据,重点对比分析重金属污染评价方法的优劣,从而为底泥污染治理提供有价值的参考和技术支撑。

Sediment pollution is one of the main reasons for deterioration of urban water environment,and sediment pollution assessment is of great significance for the selection of in-situ or ex-situ treatment.This paper discusses and summarizes the pollution assessment methods for heavy metal,organic matter and polycyclic aromatic hydrocarbons(PAHs)respectively,and compares and analyzes the advantages and disadvantages of the assessment methods for heavy metal pollution based on the column data of Maozhou River,which will provide valuable reference and technical support for sediment pollution control.
