The main objective of this study was to assess the level of mercury, cadmium and lead contamination in two species of smoked fish, Protopterus dolloi Boulanger, 1900 and Chanallabes sp, sold in the Baramoto market and widely consumed in the city of Kinshasa in the Democratic Republic of Congo. A total of 60 fish samples (30 for Protopterus dolloi and 30 for Chanallabes sp) were taken and measured using atomic absorption spectrophotometers and molecular absorption spectrophotometers. The results of the toxicological analyses revealed the presence of the three trace elements in the muscles and heads of these two species of fish in varying concentrations. The highest concentrations were found in the Protopterus dolloi species (Hg: 0.79±0.1 µg/L, Cd: 0.41±0.32 µg/L, Pb: 0.33±0.01 µg/L). However, the concentrations found in both species of fish were below the maximum limits of the standard recommended by the WHO (Hg ˂ 10 µg/L; Cd ˂ 0.5 µg/L; Pb ˂ 1 µg/L). Despite the low levels found in the muscles and heads of the fish considered in this study, regular consumption of the flesh of these fish represents a public health hazard for the population of Kinshasa, and exposes consumers to multiple risks. Further studies on the quality of smoked fish should be conducted to ensure food safety for consumers.
