Abstract:

In this paper, the current situation of heavy metal pollution in soil was discussed in such aspects of major form of heavy metal in soil, assessment index of pollution level, circulation mechanism, mutual effect of ions and remediation methods in order to study the research development of different remediation methods and the future works of heavy metal pollution. The future of research status was prospected in an effort to provide reference for other researchers. Results showed that basic research of heavy metal pollution in soil needed to be further studied, especially the circulation mechanism. Plant and microorganism remediation methods were main parts of heavy metal remediation, together with other remediation methods.
