摘要
从石门雄黄矿的兴衰,折射出砷资源开采的高潮和低谷。砷元素广泛存在自然界,砷是工业、农业、军事、半导体材料方面的重要材料。砷化合物一般具有毒性,随着环保意识的增强,人们对地表水、土壤及空气中的砷制定了严格的限量。对待砷应持"减量化、无害化、资源化"的原则,砷的最佳出路是形成可应用的产品,指出中药、有机化、建筑辅材是砷资源化的方向。
The rise and fall of realgar mine in Shimen reflects the high and low tide of arsenic resources exploitation.Arsenic,used in industry,agriculture,military and semiconductor material,is widely distributed in nature.Arsenic compounds are generally toxic.With the increasing awareness of environmental protection,people have set strict limits on arsenic in surface water,soil and air.Treatment of arsenic should hold＂reduction,harmless＂principle,and the best way is arsenic applied to products.It is pointed out that the traditional Chinese medicine,organic,building material is the direction of arsenic resources utilization.
