Hydrometallurgical Plant Chemical of Africa (CHEMAF) is causing high concentrations of ETM found today in soils and water wells, due to its liquid effluent discharges out of its site. Indeed, two transects were established at district summers Tshamilemba to collect soil and water samples in the wells distributed along the two transects. The first has 7 GW1 point, GW2, GW3, GW4 GW 11, GW12, GW13 and the second six points GW5 GW6, GW7, GW8, GW9 and GW10. Laboratory test results indicate the presence of high concentrations of trace elements in the water with 4.112 mg/L at 13 wells, 90.551mg/L in well 1 for lead. These values exceed the WHO limit value of 2 mg/L (Cu) and 0.1mg/L (Pb). Cd presents 5.234 mg/L in 1, while the threshold value is set to 0.003 mg/L. In soil, there are also copper grades ranging from 140.8mg / kg in point 11, 945.2mg/kg in 3, these values are higher than the limit value of 100 mg/kg. Copper in high contents are encountered in the sample wells on the first transect nearby CHEMAF plant. The high contents of Cu, Pb, Cd are therefore responsible for the extinction of some plant families of different skin and respiratory diseases encountered in many people (especially young people) living in this area and especially Tshamilemba pollution Environment.

Abstract
Hydrometallurgical Plant Chemical of Africa (CHEMAF) is causing high concentrations of ETM found today in soils and water wells, due to its liquid effluent discharges out of its site. Indeed, two transects were established at district summers Tshamilemba to collect soil and water samples in the wells distributed along the two transects. The first has 7 GW1 point, GW2, GW3, GW4 GW 11, GW12, GW13 and the second six points GW5 GW6, GW7, GW8, GW9 and GW10. Laboratory test results indicate the presence of high concentrations of trace elements in the water with 4.112 mg/L at 13 wells, 90.551mg/L in well 1 for lead. These values exceed the WHO limit value of 2 mg/L (Cu) and 0.1mg/L (Pb). Cd presents 5.234 mg/L in 1, while the threshold value is set to 0.003 mg/L.

Abstract: (french)
L'usine Hydrométallurgique Chemical of Africa (CHEMAF) est à l'origine de fortes concentrations en ETM constatées de nos jours dans les sols et les eaux des puits, du fait de ses rejets d'effluents liquides hors de son site. En effet, deux transects ont étés établis au quartier Tshamilemba afin de prélever les échantillons de sols et d'eaux dans les puits repartis le long de ces deux transects. Le premier a 7 points GW1, GW2, GW3, GW4, GW 11, GW12 et GW13 et le deuxième 6 points GW5, GW6, GW7, GW8, GW9 et GW10. Les résultats d'analyse de laboratoire indiquent la présence de fortes teneurs en éléments traces dans l'eau avec 4.112 mg/L au puits 13, 90.551mg/L au puits 1 pour le plomb. Ces valeurs dépassent la valeur limite de l'OMS fixée à 2 mg/L (Cu) et 0.1mg/L (Pb). Le Cd présente 5.234 mg/L au point 1 alors que la valeur seuil est fixée à 0.003 mg/L. Dans le sol, on note également des teneurs en cuivre variant entre 140.8mg/Kg au point 11, 945.2mg/Kg au point 3, ces valeurs sont supérieures à la valeur limite fixée à 100mg/Kg. Les teneurs élevées en cuivre sont rencontrées dans les échantillons des puits situés sur le premier transect à proximité de l'usine CHEMAF. Les fortes teneurs en Cu, Pb, Cd sont donc responsables de l'extinction de certaines familles des plantes, de différentes maladies dermatologiques et respiratoires rencontrées chez plusieurs personnes (surtout chez les jeunes) vivant dans ce quartier Tshamilemba et surtout de la pollution de l'Environnement.
