摘要
介绍了蚯蚓在处理城市污泥、畜禽粪便、土壤污染指示剂以及重金属污染土壤的修复等方面的应用,重点分析了在利用蚯蚓处理污染的诸多研究中,蚯蚓所表现出的随着重金属种类、暴露浓度和暴露时间的不同,选择性吸收与富集的特性以及在一定程度上受到不同重金属毒害的表现与症状,最后总结了蚯蚓利用与研究中存在的问题,并展望了其研究发展趋势。
The paper introduced the application of earthworms as soil pollution indicator, in the treatment of municipal sludge and domestic animal manure as well as the remediation of heavy metal polluted soil, and laid special stress on analyzing the treatment of pollution by earth- worms. The absorptive and accumulative characteristics of earthworms changed with different types of heavy metals, exposure concentration and time, and the earthworms were poisoned by the heavy metals to a certain extent. Finally the problems in the research and utilization of earthworms were summarized, and its future research direction was forecasted.
