污染土壤修复效果评定方法的研究

在实施污染土壤修复的环境工程后，需要通过灵敏和有效的评定方法对污染土壤修复的效果进行评定。然而，单纯依靠化学方法进行污染土壤修复效果的评定，不能揭示土壤的整体质量特征，因此需要生态毒理方法作为相互补充的手段。本文概述了植物毒性评定法、陆生无脊椎动物评定法和土壤微生物评定法及其在污染土壤修复效果评定中的应用，并对污染土壤修复效果评定方法的发展前景进行展望。

Research on evaluation methods for effectiveness of contaminated soil remediation

After environmental engineering of contaminated soil remediation is carried out,the cleaning extent of remedied soils and effectiveness of remediation action should be evaluated using sensitive and effective methods. However,remediation evaluation adopting only chemical methods could not reveal the whole characteristics of soil quality changes after remediation. The assay of ecotoxicological diagnoses is required as a complementary measure. Thus, phytotoxicity testing, terrestrial invertebrate toxicity testing, soil microorganism toxicity testing were reviewed and their application in monitoring remediation processes and evaluating effectiveness of contaminated soil remediation are expound. Furthermore,future research directions are also discussed.
