The objective of this study is to contribute to food security by evaluating the level of contamination in Trace Metallic Element (Copper) in water and in Clarias gariepinus (Burchell, 1822), a fish widely consumed in the city province of Kinshasa. It took place in the fishing sites of Kinkole and Kingabwa. The analyzes of the Metallic Trace Element (Copper) were carried out using the UV-visible spectrophotometer brand «Spectrophotometer 721». The ETM levels in the waters were respectively 17.3 mg/l and 14.7 mg/l for the Kinkole and Kingabwa fishing sites. The levels of ETM in fish were respectively 18.16 mg/kg and 19.31 mg/kg for the Kinkole and Kingabwa fishing sites. Copper bioconcentration was found in Clarias gariepinus from both fishing sites. The various results obtained show that the regular consumption of Clarias gariepinus from these two sites could have harmful effects on human health and that the bioconcentration of copper could represent a long-term risk for the fish fauna of Clarias gariepinus.

Abstract: (french)
La présente étude a pour objectif de contribuer à la sécurité alimentaire par l’évaluation du niveau de contamination en Élément Trace Métallique (Cuivre) dans l’eau et dans le Clarias gariepinus (Burchell, 1822), poisson très consommé dans la ville province de Kinshasa. Elle a eu lieu dans les sites de pêche de Kinkole et Kingabwa. Les analyses de l’Élément Trace Métallique (Cuivre) ont été effectuées à l’aide du spectrophotomètre UV-visible de marque « Spectrophotometer 721 ». Les teneurs en ETM dans les eaux ont été respectivement de 17,3 mg/l et 14,7 mg/l pour les sites de pêche de Kinkole et Kingabwa. Les teneurs en ETM dans les poissons ont été respectivement de 18,16 mg/kg et 19,31 mg/kg pour les sites de pêche de Kinkole et Kingabwa. Il a été constaté une bioconcentration du cuivre dans le Clarias gariepinus des deux sites de pêche. Les différents résultats obtenus montrent que la consommation régulière du Clarias gariepinus de ces deux sites pourrait engendrer des effets néfastes pour la santé humaine et que la bioconcentration du cuivre pourrait représenter à long terme un risque pour la faune ichtyologique du Clarias gariepinus.
