Simultaneously, by growth of industrialization and urbanization, the environmental safety of soil has become of great concerns. Based on investigating the status of soil contamination, the remediation technologies of soil contaminated by heavy metals were focused in the present study. To this aim, physical remediation, chemical remediation and biological remediation were all paid attention. To supply required references to the present study, the mechanisms of remediation, strengths and drawbacks developing trend were discussed. It is proposed that for effective and economic remediation of soil, a better understanding of remediation procedures and the various options available at the different stages of remediation is highly necessary.  UR - http://www.cas-press.com/article_101129.html L1 - http://www.cas-press.com/article_101129_a56a603bc947b52b0a83308af685f341.pdf ER -
