Katanga is one of the regions of the world, where we find abundant geochemical anomalies in most of these soils. These geochemical anomalies contain rich deposits mainly copper but also cobalt, zinc, cadmium and gold. The rich deposits of copper, cobalt, zinc, cadmium and gold are either in the hills or in the depths of the basement. Under these conditions these elements constituting a danger reduced to humans, plants and animals. From the time man, through its various activities (mining, metallurgical, plastic manufacturing) interrupts the strong links between these elements that begin the redistribution issues, release of these hazardous metals in the different compartments of environment: soil, water, air. They reach very high levels and become a real problem for humans. Atmospheric fallout from the rich fumes SO2 discharged through the chimney smelter plant Gecamines contributed to the accumulation of metals in the soils of Penga Penga-tray.

Abstract: (french)
Le Katanga est l’une des régions du monde, ou l’on trouve des anomalies géochimiques abondantes dans la plupart de ces sols. Ces anomalies géochimiques renferment des gisements riches en cuivre principalement mais aussi en cobalt, zinc, cadmium et or. Les gisements riches en cuivre, cobalt, zinc, cadmium et or sont soit dans les collines, soit dans les profondeurs du sous-sol. Dans ces conditions ces éléments ne présentent qu’un danger réduit pour l’homme, les plantes et les animaux. A partir du moment où l’homme, par ses diverses activités (exploitation minière, procédés métallurgiques, fabrication plastique) interrompt les liaisons solides entre ces éléments, que commencent les problèmes de redistribution, de relargage de ces métaux dangereux dans les différents compartiments de l’environnement: sol, eau, air. Ils atteignent des concentrations très élevées et deviennent un réel problème pour l’homme. Les retombées atmosphériques issues des fumées riches en SO2 rejetées par la cheminée de la fonderie de l’usine de la Gécamines, ont contribué à l’accumulation des métaux dans les sols du plateau de Penga-Penga. Les travaux de creusage du Quartz ainsi que la fabrication des briques ont contribué à la remobilisation de ces métaux à travers le paysage, dans le sol, l’air, l’eau et constituent un problème sérieux de santé publique dans cette partie de la ville de Lubumbashi.
Author Keywords: Katanga, anomalies géochimiques, activités anthropiques, retombées atmosphériques, SO2 redistribution, Cu, sol, eau, air.
