铅锌矿区的植物修复研究进展

摘要

Lead-zinc mine brings wealth,but also serious pollutions to environment and harms to people＇s health.Starting from current problems of lead-zinc mine areas,this paper summarizes the former studies on toxicant mechanisms of lead-zinc against plants,filtrations for hyperaccumlators of heavy metal in contaminated soil and application progresses,discovering that there is no unified repository of hyperaccumulators and accumulators.It is easy to cause waste of resources by doing repeat experiments.Most researches are limited to pot and hydroponic experiments and large-scale testing of Pb-Zn mine and engineering applications are less.Fails to apply the test results in real practice slow down the phytoremediation process of Pb-Zn mines.This paper proposes to combine plant,soil and animal so as to repair the Pb-Zn mine areas.%铅锌矿在给人们带来财富的同时,也给环境带来了严重的污染,对人们的健康造成危害,本文从铅锌矿区存在的问题着手,综述了前人对植物毒害机理、富集植物筛选及工程应用的进展,发现中外没有统一的重金属超富集植物和富集植物的资源库,容易进行重复试验,浪费资源,且植物修复的研究大多数局限于盆栽和水培试验,大规模的铅锌矿区试验和工程应用较少,未将试验成果及时运用于实践,使得铅锌矿区修复进程缓慢,建议将植物-土壤-动物进行组合修复铅锌矿区。
