| 摘 要： | 砷是一种易使人致癌和对动、植物生长有较大危害的有毒微量元素。我国的砷矿资源主要以伴生砷矿赋存于有色多金属矿床中,含砷有色多金属矿床的采、选、冶加工等,是砷污染的最主要来源,含砷废石尾矿的大量堆积被氧化和淋滤溶解,砷对矿区下游水体、农田和生态环境都造成不同程度的污染危害。针对砷的污染危害,从废水治理、土壤生态治理、生物修复及综合利用等方面提出了治理砷污染的对策。

| Abstract: | Arsenic is a kind of trace element with toxin,which can cause human cancer and is harmful to the growth of animals and plants.In China,the arsenic resources exist in nonferrous multi-metal deposits mainly in the form of associated arsenic.The mining,mineral separation,smelting and processing of arsenic-bearing nonferrous metal ores are the dominant sources of arsenic pollution,including oxidation and dissolution of eluviations of piles of arsenic waste rocks and tailings.Arsenic has threatened downstream wa... |
