摘要: 蚯蚓的各类活动能够改善土壤理化性质,提高土壤微生物活性,引入高效降解菌等,直接或间接地促进有机污染物在土壤中的降解和转化。其中蚓触圈是有机污染物降解的热点区域。此外,生物富集也是蚯蚓修复土壤有机污染的重要机理之一。研究表明,蚯蚓能够促进土壤中多种有机污染物的降解,在土壤有机污染生物修复方面具有广阔的应用前景。本文综述了蚯蚓在土壤有机污染生物修复中的作用机理及在修复多环芳烃、多氯联苯、农药等污染土壤方面的应用,指出当前研究存在的不足,并对未来研究进行展望,以期为土壤有机污染生物修复提供参考和依据。

Abstract: Earthworm can improve soil physicochemical properties, enhance microbial activities, introduce high-efficiency biodegrading microbes, and directly or indirectly promote the degradation and transformation of organic pollutants in soil. Due to the high abundance and activities of microorganisms, drilosphere is a hot spot for the degradation of organic pollutants. In addition, bioaccumulation is one of the important mechanisms for earthworm remediation of soil organic pollutants. It is reported that earthworm can promote the degradation of various organic pollutants in soil, with broad application prospects in soil bioremediation. We reviewed the mechanisms of earthworm in the remediation of soil polluted with organic contaminants, and its application in remediating soils contaminated by polycyclic aromatic hydrocarbons, polychlorinated biphenyls, pesticides, etc. Knowledge gaps were pointed out and needs for future research were discussed. This review provides reference and basis for the bioremediation of organic polluted soils.

Key words: soil, earthworm, drilosphere, organic contaminant, bioremediation.
