The lack of modern equipment management and recycling of waste from the enrichment process metals made the Hydrometallurgy Lubumbashi is the cause of high concentrations of metals found today in the waters, soils and that plants, due to liquid effluent discharges untreated out of Copper and Cobalt production sites. Transects were established along rivers (Lubumbashi receiving effluents Society Terril de Lubumbashi (STL), and Oven Electric Lubumbashi (FEL) and Naviundu which it receives Chemical Of Africa (CHEMAF) in the to determine the levels of Cu content, Co, Pb, Fe in the samples of water, soil and Plant to highlight the potential risks of humans living in such an environment. The results of study indicate a critical environmental problem in view of the values obtained after laboratory analysis performed on water samples, soil and plant harvested on the ground.
