Environmental Assessment Chemical Contamination Abandoned

项目摘要

Abandoned mines pose serious risks to the environment, through the release of pollutants on land, rivers, and air. Thus, harming plants, aquatic organisms, other animals and human health in areas of high pollution. In Nigeria, over 1200 abandoned mine lands (AMLs) have been identified. To date, only a few have been reclaimed due to the high costs. Many non-reclaimed AMLs have pond waters that are being used for irrigation, fishing, domestic and industrial purposes exposing humans to risk of significant harm. The project aims to develop an integrated impact assessment methodology for chemical contamination emanating from abandoned coal and mineral mines. The case of Nigeria will inform this work by identifying and quantifying the chemical contaminants, with a focus on the interactions that exist between the different media around the mines to ascertain the extent, fate, mobility and impacts of the contaminants on receptors by accounting for the risk of exposure to multiple pollutants via multiple sources. A multidisciplinary approach involving geological, geochemical, hydrological, and biological analysis would be employed in this study. The outcome would be used to develop policy recommendations for decision makers on long-term site management and mine closure with environmental regards to protection of the environment and humans depending on it.

废弃矿山通过向土地、河流和空气中释放污染物，对环境构成严重威胁。因此，在高污染地区危害植物、水生生物、其他动物和人类健康。在尼日利亚，已经确定了1200多个废弃的地雷地。到目前为止，由于成本高昂，只有少数被回收利用。许多未开垦的人工湿地有池塘水，被用于灌溉、捕鱼、家庭和工业目的，使人类面临重大危害的风险。该项目的目的是为废弃的煤矿和矿坑产生的化学污染制定综合影响评估方法。尼日利亚的案例将通过确定和量化化学污染物为这项工作提供信息，重点关注矿山周围不同介质之间存在的相互作用，通过考虑通过多种来源接触多种污染物的风险，确定污染物对受体的程度、命运、流动性和影响。本研究将采用多学科方法，包括地质、地球化学、水文和生物分析。研究结果将用于为决策者制定关于长期场址管理和矿山关闭的政策建议，其中涉及保护环境和依赖环境的人类。
