To the best of our knowledge, this study is the first to focus on the environmental assessment of heavy metals in the abandoned mining district of Kef Oum Teboul (KOT), which is located in the northeastern part of Algeria in an area classified by Ramsar as a Biosphere Reserve since 1990. KOT was one of the primary deposits of copper in the last century, and its releases are stored as dams that seriously threaten the environment. To assess the degree, distribution and sources of contamination approximately the mining area, liquid and solid samples were collected from the mining waste, the soils, and the stream sediment. The samples were analyzed to determine the pH, conductivity and contents of heavy metals (Pb, Zn, Cu, and Cd). The mining areas are characterized by high contents of heavy metals that exceed all norms, and the metal contents significantly decrease at significant low distances from these sources. According to the statistical methods used in this study (I-Geo, Pi, RI), the stream sediments and the soils are uncontaminated to moderately contaminated by Cu and Zn, moderately contaminated by Pb, and extremely contaminated by Cd.

据我们所知，本研究是第一个侧重于废弃的Kef Oum Teboul（KOT）矿区的重金属环境评估的研究区，该矿区位于阿尔及利亚的东北部，被拉姆萨尔（Ramsar）分类为自1990年以来一直是生物圈保护区。KOT是上个世纪的主要铜矿床之一，其释放物以大坝的形式存储，严重威胁环境。为了评估采矿区附近的污染程度，分布和污染源，从采矿废料，土壤和溪流沉积物中收集了液体和固体样品。分析样品以确定pH，电导率和重金属（Pb，Zn，Cu和Cd）的含量。矿区的特点是重金属含量超标，并且在距这些源极低的距离处金属含量显着降低。根据本研究中使用的统计方法（I-Geo，Pi，RI），河流沉积物和土壤未受到污染，受到Cu和Zn的中等污染，受到Pb的中等污染，而受到Cd的极度污染。
