基于风险和特定组分的石油烃污染土壤修复基准/标准研究方法进展与展望

Advancement and Prospect on Researching Methodology of Risk-Based and Chemical-Specific Petroleum Hydrocarbons Remediation Criteria /Standards for Contaminated Soils

目前我国还没有相关的修复标准来指导石油烃污染土壤的修复工作,国外的研究方法对于我国石油烃污染土壤修复标准的制定具有方法学上的借鉴意义。本研究首先从污染土壤修复基准/标准的含义和石油烃的分类法两个方面,简要阐述了石油烃污染土壤修复基准/标准的内涵;然后介绍了国外污染土壤修复基准/标准的分级方法,接着就风险评价及相关模型的运用以及其分析方法和指示物/替代物的研究进行了概述;最后简要归纳了国外石油烃污染土壤修复基准/标准的总体研究方法,并对今后的研究方向进行了展望。

There are no relevant remediation standards to conduct the work for remediation of petroleum hydrocarbon contaminated soils in China. Thus, the researching methods for derivation and enactment of remediation criteria and standards for hydrocarbon contaminated soils in foreign countries are of signifi- cance for methodological references. In this work, the connotation of remediation criteria/standards for petroleum contaminated soils was briefly expounded from two aspects, namely, the meaning of the reme- diation criteria/standards and the classification method of petroleum hydrocarbons. Then, the tiered methods from foreign countries were introduced, followed by the summarization of application of risk as- sessment and their relevant models, the research about the analytical methods and the indicators/surro- gates. At last, the general researching methods of remediation criteria/standards for petroleum contami- nated soils were concisely concluded, and the further research in this direction was prospected.
