污染土壤的生物标记物研究进展

Advances in the research of biomarkers of contaminated soils

生物标记物是指示环境中污染物危害效应的生物信号。利用生物标记物进行污染土壤的检测和定量分析是最可行的方法之一。本文主要综述了近年来一些典型的、指示土壤污染的几类生物标记物 (如细胞色素P4 5 0加氧酶系统、细胞抗氧化酶及DNA指纹技术 )的最新研究进展 ,并探讨了生物标记物在污染土壤修复效果评价及其早期诊断方面的应用前景。

As biological responses that indicate deleterious effects of contaminants on the environment,biomarkers are one of the most effective ways of monitoring and analyzing contaminated soils quantitatively.In this paper,the latest advances in some typical biomarkers indicating soil pollution,such as cytochrome P450 enzymes,antioxygenases in cells and the DNA fingerprint technique were reviewed.Application prospects for assessment and early diagnosis of the bioremediated effectiveness of contaminated soil by these biomarkers were discussed.
