摘要
针对江西德兴铜矿、安徽铜陵铜矿和江苏九华铜矿的矿区典型污染土壤现状进行了初步研究,分析了铜矿区环境现状,提出了一些可能对策的建议。研究发现,3个矿区典型污染土壤各自表现出不同的污染状况。三个铜矿尾矿砂中铜含量超标,其高低次序为德兴铜矿>铜陵铜矿>九华铜矿,而锌含量顺序依次为铜陵铜矿>九华铜矿>德兴铜矿。矿区周围土壤以铜污染为主,锌有部分超标情况发生。同时,在矿区典型土壤生长的作物中,铜、铅、锌、镉都有超标的情况,部分作物重金属含量超过食品卫生标准达10—20倍之多。被调查的多种植物中也存在重金属含量过高的结果。
Primary study of typical pollution soils in the copper mines of Dexing (Jiangxi), Jiuhua (Jiangsu) and Tongling (Anhui) was carried out. It has been f ound that pollution of heavy metals on these soils was different among these exa mined copper mines. The polluted soils contained high copper, and the order rank s in: Dexing > Tongling > Jiuhua. In terms of Zn, the order in: Tongling > Jiuhu a > Dexing. It was discovered that copper was the main pollutant in the soils st udied, and Zn exhibited in over-dosage in comparison with the environmental qua lity standard in several soils tested. Meanwhile, the contents of heavy metals i n plants were found to be also high, even as high as 10 — 20 times of the conce ntration of the background value in the studied soils. Environmental status in t he copper mines is discussed and some countermeasures are proposed in the presen t paper.
