摘要
阐述了采矿对环境造成的负面影响 ,包括 :尾矿或废石堆中的杂质元素会进入表生地球化学循环 ,在不同气候条件下 ,呈现不同的特征模式 ,尾矿氧化带的酸性水的排放 ;矿山污染源对周围土壤和植物的影响使重金属元素等进入食物链 ,对人类和动物健康造成威胁。根据国内外的最新研究动向 ,指出建立环境地球化学模式 ,对采矿环境污染作出客观的监测和评价 ,能为防止污染和治理环境提供可靠的地球化学依据。
The article discusses adverse effects of mining on the environment.These effects include hypergene geochemical circulation of impurity elements from mine taitings and waster rocks that show different characteristics;acidic drainage from the oxidation of sulphide minerals in tailings;influence of mine pollution on soil and plants as it is capable of entering food chains,presenting a serious treat to human and animal health.It is pointed out that research on environment geochemical model,and monitoring and assessment of pollution caused by mining activities will provide a basis for the prevention of environmental problems.
