Environmental Assessment of Chemical Contamination from Abandoned Coal and Mineral Mines: A multidisciplinary approach

废弃的矿山通过在土地、河流和空气中释放污染物，对环境构成严重风险。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，已确定1200多个废弃矿场。到目前为止，由于成本较高，只有几个人被回收。许多未回收的AML的池塘水被用于灌溉、捕鱼、家庭和工业目的，使人类面临重大伤害的风险。该项目旨在为废弃煤矿和矿场产生的化学污染制定一种综合影响评估方法。尼日利亚的案例将通过查明和量化化学污染物，重点放在矿场周围不同介质之间的相互作用，通过考虑通过多种来源接触多种污染物的风险，确定污染物的程度、去向、流动性和对受体的影响，从而为这项工作提供信息。这项研究将采用涉及地质、地球化学、水文和生物分析的多学科方法。结果将用于就长期场地管理和矿场关闭以及与保护环境和人类赖以生存的环境有关的环境问题向决策者提出政策建议。

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.
