摘    要:介绍了土壤重金属的形态及各种分析方法,重点说明了土壤中重金属形态分布及影响因素;讨论了影响土壤环境中重金属形态转化的因素,重金属形态与重金属在土壤中的迁移性、可给性、活性的关系,重金属污染土壤修复与重金属形态分布的关系.形态分析在一定程度上反映自然与人为作用对土壤中重金属来源的贡献,并反映重金属的生物毒性.重金属可以因形态中某一个或几个方面不同而表现出不同的毒性和环境行为.

关 键 词:土壤  重金属  形态  形态分析

Abstract:This paper introduced the chemical forms of soil heavy metals and their analytical methods, with the focus on the distribution and conversion of different form heavy metals and their affecting factors. The chemical forms of soil heavy metals are of significance for evaluating their mobility and bioavailability, and the possibility of soil remediation, while chemical form analysis could reflect the contributions of natural and human activities to the sources of soil heavy metals and their ecotoxicities. Soil heavy metals could have different toxicities and environmental behaviors due to their chemical form conversion.
Keywords:soil  heavy metal  chemical form  chemical form analysis
