The main objective of this study is to determine the levels of copper (Cu), cobalt (Co) and Cadmium (Cd) translocated into the leaves of Amarante, cabbage and spinach grown on the soil of the river Lubumbashi, rich in metals trace elements (MTE). Mining (industrial and artisanal), movement of vehicles, increased metallurgical based activities, domestic and agricultural activities in the city of Lubumbashi remain the causes that contribute to entry, mobility and the transfer of MTE in Environmental compartments: water, soil, sediment and air. These have nowadays very high MTE contents, creating severe malfunctions for human life, plants, soil, aquatic beings. The results obtained showed that spinach has accumulated a significant part of all elements studied and analyzed in the shoots, he accumulated more Cu (T0: 15ppm and T1: 31ppm). These levels far exceed the threshold set at 10 ppm in food. He has accumulated a lot of Co (T0: 10ppm; T1: 12ppm) that Amarante (T0: 1.8ppm) and cabbage (T0: 2.3ppm). The CD shows an opposite situation on the ground of the experimental field (T0), it is found to 7.8ppm Amarante, 14ppm: Cabbage and 9ppm: spinach. Leaves of consumption (spinach, cabbage and Amarante), grown on the soil of the river Lubumbashi rich MTE and having accumulated a lot of ETM in their aerial parts (edible) could create risks of food poisoning on the human health.
