Assessment of soil contamination by heavy metals and arsenic in Tamesguida abandoned copper mine area, Médéa, Algeria.

Heavy metal and arsenic pollution of soil remains a serious environmental problem long after mining operations have ended. For instance, the Tamesguida copper mine located in north-central Algeria has been abandoned for several decades without restoration or even an environmental impact assessment. Therefore, soils were collected from several locations in the vicinity of the old mine and tailings and analyzed for their Cu, Cr, As, Pb, Ni, Zn, and Fe rates to gauge the scope of the soil contamination caused by these elements, and assessing their origin and their dispersion in the mine area.
