广西锰矿区重金属污染现状及治理对策研究综述

A review of pollution status and countermeasures of heavy metalpollution in Guangxi Manganese mining areas

基于广西锰矿区土壤及植被重金属污染现状,分析了重金属的地域分布特征和危害,提出了治理措施。分析认为:广西锰矿区的土壤和植被均受到多种重金属元素的复合污染,各矿区均受到Mn、Cd的重度污染,中度、轻度污染元素具有地域差异;重金属污染主要分布于矿产储量高、开发力度大的矿区;超富集植物对重金属污染的修复效果显著,建议加强超富集植物的筛选及培育。

Based on the status of heavy metal pollution in soil and vegetation in the manganese mining area in Guangxi Province,the regional distribution characteristics and hazards of heavy metals were analyzed,and control measures were proposed.The results show that the soil and vegetation in Guangxi manganese mining area are all polluted by multiple heavy metal elements.All the mining areas are heavily polluted by Mn and Cd.The moderately and slightly polluted elements shows regional differences.Heavy metal pollution mainly distributes in highly-developed mining areas with high mineral reserves.Hyperaccumulator plants have a significant repair effect on heavy metal pollution.It is recommended to strengthen the screening and cultivation of hyperaccumulator plants.
