摘要
矿山固体废物和酸性废水已成为矿山资源开发的两大环境公害,与此产生的矿山重金属污染也成为人们关注的焦点。矿山重金属和类金属元素在人类改造过的环境中发生的活化、迁移和再分配,必然对矿山开发区和邻近区的地球化学平衡带来新的扰动。研究重金属元素在这种地球化学过程中的扰动与平衡,可以揭示污染元素的迁移循环、形态转化规律及其对生态环境的危害,对矿山重金属的污染治理、环境影响评价和生态修复具有重要的指导意义。
Solid wastes and acid water in mine exploitation become two major environmental pollution sources. Meanwhile, heavy mental pollution is becoming a concerning focus in the process. The activation, migration, and redistribution of heavy metal and metalloid elements in reconstructive areas must disturb the balance of geochemistry of mine areas and their vicinity. Studying the disturbance of geochemistry in this process helps to reveal the rule of transference, circulation and phase transformation of contaminated elements and their harms to ecosystem. The research is of great importance in dealing with mining pollution, ecological rehabilitation and environmental assessment.
