蔬菜产地土壤重金属污染评价及源解析

The Source Apportionment and Assessment of Soil Heavy Metal Pollution in Vegetable Field

介绍了目前我国蔬菜产区土壤重金属污染状况和常用的评价方法,简述了内梅罗指数法、地质累积指数法等评价土壤重金属污染的重要方法,分析了各种评价方法的优缺点并对其进行了比较;归纳了蔬菜产区土壤重金属源解析分析方法,得出源解析分析方法一般分为多元统计分析、空间识别和化学形态分析,从而为准确合理评价蔬菜产区土壤重金属污染提供科学依据。

In this paper,the status of soil heavy metal pollution in vegetable field and the evaluation methods are introduced.The important methods of soil heavy metal pollution evaluation such as the Nemerow index method and the geologic accumulation index method are briefly introduced.The advantages and disadvantages of various evaluation methods are analyzed and compared.The analytical methods of heavy metal sources in vegetable producing areas are summarized,which are generally divided into multiple statistical analysis,spatial identification and chemical form analysis.This study provides scientific basis for the accurate and reasonable evaluation of heavy metal pollution in vegetables producing areas.
