污染土壤修复基准值推导和确立的原则与方法

污染土壤修复标准是土壤环境标准体系中一个不可缺少的组成部分。为了响应污染土壤修复效果评定与污染应急事件处理的需求,我国需要尽快制定符合自身实际情况的污染土壤修复标准来指导修复评定工作,而污染土壤修复基准的确立可以为污染土壤修复标准的制定提供数据支持和科学依据。因此,污染土壤修复基准的研究具有十分重要的实践意义。本文首先对污染土壤修复基准的内涵进行了简要的概述;在此基础上,以美国、加拿大、荷兰和丹麦这4个国家的研究进展为例,详细阐述了它们对污染土壤修复基准值推导和确立的原则与方法。最后,归纳了国外污染土壤修复基准值推导和确立的总体方法,并且对我国污染土壤修复基准的研究进行了展望。

The Principles and Methods of Deriving and Determining Remediation Criteria for Contaminated Soils

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.
