Abstract
The content of five heavy metals (zinc, copper, iron, cadmium and lead) in muscles and skin has been studied for one most consumed fish species (Auxis rochei, Risso, 1810) from the Mediterranean Sea coast of Libya Misurata. The metals content of muscles and skin were determined by an inductively coupled plasma mass spectrometer (ICP-MS) (Agilent 200 Series AA-Agilent Technologies, Assembly Fume Extraction, Part No.: 210190000, Serial No.: MY14520002). The current study, it has been shown that the skin of Auxis Rochei has registered the highest concentration of Zn, while Fe was found to be highest in the muscles. On the other hand, the lowest contents of Cd and Pb were recorded in both muscles and skin. The arrangement of metallic elements in the studied tissues followed the following sequence: iron > copper > zinc > lead > cadmium. However, in the skin tissue, the sequence was reversed with zinc first, followed by iron > copper > lead > cadmium. The values obtained from metal detection in the muscles and skin of fish in the current study were below the limits allowed by FAO/WHO and EFSA. Conclusions The current results show that fish is one of the most indicative factors for estimating trace metals pollution in marine systems. Therefore, monitoring and analyzing fish populations is necessary to safeguard both the environment and public health.
