【摘要】 对某金-铜矿山矿山的自然植被、矿区内外的土壤和水系进行金属污染分布特征及其迁移转化进行了系统地研究.结果表明:该矿的开采对矿区环境造成严重的重金属环境污染,水体污染程度要大于土壤污染程度,该矿区水体造成的是重污染,多金属复合污染,综合污染指数PI为12.084~83.848,不同重金属对地表水造成的污染程度分别为:As>Cu>Zn>Cr,分别为国家Ⅲ类地表水标准的45.06、30.95、7.16和3.88倍.该矿区的土壤已造成轻等污染,其综合污染指数PI为1.038~1.856,平均为1.4515,其Cu和As分别是土壤环境质量三级标准(GB 15618-1995)11.406倍和2.774倍.矿区的植物也已经受到重金属污染,其Cu和As的含量分别是背景植物的5.21倍和3.90倍.更多还原

【Abstract】 Samples of water,soil,plants were collected from one gold-copper miner area.It was shown that the soil and water were heavy metal contaminated.Pollution is more serious in water than in soil.The water was serious pollution.The Pollution Index is 12.084～83.848.The contamination degree of As,Cu,Zn,Cr was 45.06,30.95,7.16,3.88 times as much as the national standard III of water quality,respectively.The soils were pollution,too,and contaminated mainly by Cu and As.The contamination degree of Cu and As was 11.206,2.774 times as much as the national standard 3 of soil quality,respectively.The plants were contaminated mainly by Cu and As.The contamination degree of metals was 5.21 and 3.90 times as much as the average concentrations.更多还原
