The Remediation Standards and Evaluation Methods for Remediation Effectiveness of Contaminated Soil

摘要

The contaminated soil remediation standard formulation's aim is under the premise of ensuring the reuse of contaminated land, to reduce or cut the contaminants which cause to receive in the more serious contaminated soil environment is insufficient to lead to greater ecological damage and health risks. In this paper, some suggestions on the establishment of remediation standards for contaminated soils such as clean technology factors, factors of soil background values, standards and regulations to control pollution of ecological factors and assessment of toxicological risks were put forward, based on the analysis of the disadvantages of soil environmental quality standard research on evaluation methods for remediation effectiveness of contaminated soil, commonly used evaluation methods, such as phytotoxicity testing, terrestrial invertebrate toxicity testing, soil microorganism toxicity testing and biomarker assessment methods were described. Furthermore, future research directions were also discussed.
