Ecological remediation of contaminated soil: Theoretical connotation, measures, and applications
摘要
Abstract
This paper discussed the theoretical connotation of ecological remediation of contaminated soil, related measures, their optimal combination, and case applications. The goals of ecological remediation of contaminated soil were expanded as: Decreasing target pollutants to acceptable level, decreasing soil eco-toxicological properties to acceptable level, and recovering part or all soil ecosystem scrvices. Five characteristics and five principles of ecological remediation of contaminated soil were summed up, and the principles of optimal combination of related measures were proposed. At present, the optimal combinations of related measures have the characteristics of taking plant and microorganism as the core and of simultaneous and asynchronous. In the case applications, the process of ecological remediation of contaminated soil is: Background investigation → improving basic environment conditions → bioremediation → evaluation. Though the optimal combination of related measures is the key in ecological remediation of contaminated soil,its mechanisms should be further studied. In addition, to promote the conversion of laboratory study to actual application is an inevitable problem in the studies of ecological remediation of contaminated soil. It is the foremost to further enrich and improve the theoretical connotation of ecological remediation of contaminated soil and to establish related theoretical framework.关键词
