两种河道底泥重金属污染生态危害评价方法比较研究

TWO ASSESSMENT METHODS OF HEAVY METAL POLLUTION OF RIVER SEDIMENT ECOLOGICAL RISK

河道底泥作为特殊的物质形态,其评价方法与土壤和水环境评价方法均有所差异。随着河道底泥重金属污染问题越来越受到人们的关注,针对河道底泥重金属污染的评价方法也大量涌现。着重介绍了Hakanson生态风险指数法和污染负荷指数法两种操作简单、使用方便的常用方法,重点针对方法本身以及该种方法的优缺点。

River sediment, as a special physical form, whose evaluation method was different from that of soil and water enviroments. Along with the river sediment heavy metal pollution problem has gotten more and more attention, the evaluation methods of heavy metal pollution in sediment got a rash. Hakanson ecological risk index method and pollution load index were introduced here, focusing on the advantages and disadvantages of two methods.
