摘    要:随着工农业的发展,重金属对土壤和农作物的污染问题越来越突出,对土壤重金属的修复研究也越来越重要。蚯蚓作为土壤环境中最常见的无脊椎动物在生活过程中的摄食、做穴、移动、排便等行为都会对土壤重金属产生影响。通过对蚯蚓粪作为土壤重金属污染修复剂的潜力进行总结、分析,对蚯蚓粪修复土壤重金属污染的研究方向提出了建议与展望。

关 键 词:土壤重金属污染  重金属生物有效性  蚯蚓粪  钝化  活化

Abstract:With the development of industry and agriculture,heavy metal contamination of soil and cropper is more and more serious.And the studies about the remediation of soils become more and more important.Earthworm as one of universal invertebrates in soil,its acts including food-intake,burrow and excretion can influence the activity of heavy metals.In this review,we consider whether the earthworm cast can change heavy metal bioavailability and make some proposals on the remediation of soils.
Keywords:heavy metal  soil contamination  bioavailability  earthworm feces  immobility  activation
