土壤锌污染及其修复技术研究进展

Research Advances on Zinc Pollution and Remediation of Soil System

伴随着矿山开采、城市化进程、交通运输、农田污灌、污泥农用以及肥料的施用,使大量锌元素进入土壤系统,已严重威胁着生态环境和人类健康,土壤锌污染治理与修复迫在眉睫。本文综述了土壤锌含量、污染来源、锌的营养作用及其毒害效应方面的研究成果,主要讨论土壤锌污染修复所采取的各类措施,包括物理修复、化学修复及生物修复措施,提出土壤锌污染及修复技术研究存在的问题,并对未来的研究工作做了进一步的展望。

With the strengthening of human activities,more and more zinc had enter soil system.This course included mining,urbanization,transportation,application of fertilizer and sewage sludge,etc.The soil Zinc pollution had threaten environment and human health,so soil pollution control and remediation was very important.Therefore,this paper reviews the research results on the content,pollution sources,nutrition and toxicity of Zinc.In this paper,harness approaches including engineering control,chemoremediation and bioremediation were summarized.Finally,this summary high lights existing problems of Zinc Pollution and Remediation of Soil System,meanwhile this paper suggests future directions for progress.
