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.

Abstract
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).

Abstract: (french)
L'objectif principal de cette étude a été de déterminer les teneurs en Cuivre (Cu), Cobalt (Co) et Cadmium (Cd) transloqués dans les feuilles d'Amarante, de chou et d'épinard cultivés sur le sol du bord de la rivière Lubumbashi, riche en éléments traces métalliques (ETM). L'exploitation minière (industrielle et artisanale), la circulation des véhicules de transport, l'intensification des activités d'origine métallurgique, les activités domestiques, agricoles dans la ville de Lubumbashi demeurent les causes qui contribueraient à l'entrée, la mobilité et au transfert des ETM dans les compartiments de l'Environnement: eau, sol, sédiment et air. Ceux-ci présentent de nos jours des teneurs très élevées en ETM, créant des dysfonctionnements sévères pour la vie de l'homme, des plantes, des sols, des êtres aquatiques. Les résultats obtenus ont montré que l'épinard a accumulé une part importante de tous les éléments étudiés et analysés dans les parties aériennes, il a accumulé plus de Cu (T0:15ppm et T1: 31ppm). Ces teneurs dépassent largement la valeur seuil fixée à 10ppm dans les denrées alimentaires. Il a accumulé beaucoup de Co (T0:10ppm; T1:12ppm) que l'Amarante (T0:1.8ppm) et le chou (T0:2.3ppm). Le Cd montre une situation inverse sur le sol du champ expérimental (T0), on le trouve à 7.8ppm: Amarante, 14ppm: Chou et 9ppm: épinard. La consommation des feuilles (Epinard, chou et Amarante), cultivés sur le sol du bord de la rivière Lubumbashi, riche en ETM et ayant accumulés beaucoup d'ETM dans leurs parties aériennes (comestibles) pourrait engendrer des risques d'intoxication alimentaire sur la santé humaine.
