土壤重金属污染来源及其解析研究进展

土壤重金属污染问题是环境和土壤科学研究者关注的热点问题。对土壤重金属污染物来源的鉴别是准确、有效控制和治理污染源的前提。根据近年来国内外对土壤重金属污染的相关研究报道,综述了土壤中污染物的工业、农业和交通因子三大主要来源,重点阐述了目前解析土壤重金属污染来源所运用的化学形态研究、剖面分布、同位素示踪、空间分析和多元统计等方法,并就存在的问题和今后的研究重点进行了总结。

Research Progress in Sources Identification of Soil Heavy Metal Pollution

Environment and soil scientists were paying more and more attention to the issue of soil heavy metal pollution.Source identification of heavy metals was the precondition of preventing and controlling pollution.Based on the related researches of recent years,a review with 38 referemces is given on the sources of soil heavy metal pollution from industrial,agriculture and transportations.with emphasies on the methods of source identification such as element speciation,profile distribution,spatial analysis and multivariate statistical approach.A conclusion was made at last.
