| The remediation standard for contaminated soils is an indispensible part of the soil-environmental standard system. In response to the requirement of assessing the remediation efficiency of contaminated soils and handling emergency pollution incidents, the enactment of the remediation standards for contaminated soils based on the actual situation in China is urgently needed. Moreover, research on the remediation criteria for contaminated soils can provide with data support and scientific grounds for the enactment of remediation standards for contaminated soils. Thus, the development of the remediation criteria for contaminated soils is of great significance in practice. The connotation of the remediation criteria of contaminated soils was firstly explained in brief. Then, USA, Canada, the Netherland and Denmark were chosen as the typical examples, in particular, the principles of deriving the remediation criteria for contaminated soils were elaborated, and the method system of deriving and determining the remediation criteria for contaminated soils was summarized. In the end, future research on contaminated soil remediation criteria was prospected. |
