重金属污染对土壤动物的毒性效应研究进展

Research Advances in Heavy Metal Toxicity Effect to Soil Animals

土壤重金属污染可导致土壤生物多样性丢失、土地质量退化,重金属的传递甚至威胁到人类的生命安全,如何及时发现并治理污染已经受到人们越来越多的关注。土壤动物的主要类群与土壤生态系统各方面的信息密切联系在一起,常被作为土壤质量评价的重要生物学指标。着重介绍重金属物质对常见土壤动物群落结构、活动、取食、繁殖等方面的影响,同时探讨重金属物质对土壤动物的生理毒性等方面影响的热点问题。

Heavy metal pollution result in soil biodiversity loss,soil quality degeneration and heavy metal transfer,even threatened human health.How to find and control pollution in time got more and more attention.The information of the main soil animal ’s species was closely related to soil ecosystem in all aspects,which was often used as a significant biological index to evaluate soil quality.This article summarized the influence of heavy metal toxicity to soil animal ’s community structure,activity,food searching,reproduction,and physiological toxicity and so on.
