Contribution à l'étude écotoxicologique du Cadmium et du Plomb dans Distichodus fasciolatus, Mormyrops anguilloides et Schilbe mistus au Pool Malebo (Fleuve Congo- Kinshasa/RD Congo) à MALUKU [ Contribution to the ecotocological study on Cadmium and in Lead contamination of Distichodus fasciolatus, Mormyrops anguilloides and Schilbe mistus (Pisces) from the Pool Malebo at MALUKU upstream Kinshasa city (Congo River, DR Congo) ]

This survey carried out from September 2009 to September 2013 at Maluku, upstream Kinshasa city at the entrance of the Malebo Pool (Congo River, Kinshasa, DR Congo) on three common fish species selected according to their food-chain position. We focused on the contamination in Lead and cadmium of Distichodus fasciolatus (herbivore), Mormyrops anguilloides (carnivore) and Schilbe mistus (carnivore)(Pisces). We analysed fish heads and flesh according to their size (juveniles and adults). Results revealed that Schilbe mistus was the most contaminated and Distichodus fasciolatus the least contaminated. Adults were more contaminated than juveniles, and heads than flesh. Compared to previous study at Kinsuka, we are proud to conclude that the Congo River ecosystem at Maluku is safe and fish can be eaten without any fear as contaminations are lower than WHO standards. However, the herbivorous species appeared less contaminated than the secondary and the tertiary species (carnivores and omnivores, respectively).
