Citation: Mehouel F, Bouayad L, Hammoudi AH, Ayadi O, Regad F (2019) Evaluation of the heavy metals (mercury, lead, and cadmium) contamination of sardine (Sardina pilchardus) and swordfish (Xiphias gladius) fished in three Algerian coasts, Veterinary World, 12(1): 7-11.

Aim: This study aimed to evaluate mercury (Hg), cadmium (Cd), and lead (Pb) levels in 70 samples of sardine (Sardina pilchardus) and 30 samples of swordfish (Xiphias gladius) fished in the Algerian coasts.

Materials and Methods: After the mineralization of the fish samples through the pressure digestion, the analyses were carried out by inductively coupled plasma atomic emission spectroscopy.

Results: Mean concentrations of Hg, Cd, and Pb in sardine were 0.62, 0.55, and 2.13 mg/kg wet weight, respectively, while in swordfish, the concentrations were 0.56, 0.57, and 3.9 mg/kg wet weight, respectively. These results exceeded the Algerian and European legislation threshold values, whereas Hg's concentration in swordfish remained close to and did not exceed the recommended thresholds (0.56 mg/kg wet weight).

Conclusion: This fish may represent a hazard for consumers in Algeria. Systematic and periodic controls of heavy metals in fish are recommended, and risk assessment is needed to protect the consumer.

Keywords: atomic emission spectroscopy, fish, hazard, heavy metal, sardine, swordfish.
