Abstract:
The study focused on the current research on determining the concentrations of some heavy metal elements (Cd, Pb, Cu, Zn) in the fleshy tissue of Mugil cephalus fish species, on the Syrian coast of Tartous Governorate, as fish samples were collected for two whole years from March 2019 to February 2021, and from three areas on the shore of Banias city: the estuary area of the Jobar River, the estuary area of the Baniyas River, and Al-Basiya Beach. Atomic absorption spectroscopy (AAS) technology was used by wet digestion method (Wet-Digestion-Method) for fish samples, where the concentrations of the two elements (Zn, Cu) were detected using flame-AAS technology, while the trace elements (Cd and Pb) were detected by electrothermal ablation technology (ETA-AAS) because its concentrations are below the detection threshold by the flame method. The results of the study showed a higher concentration of heavy metals in the muscles of Mugil cephalus in the estuary area of the Jobar River than in the other two sites, followed by the Banias River estuary area, and then the Basiya area, where the average rates of the concentrations of these elements in all studied sites during the study period ranged between (8.803-13.095 µg/g wet weight) for zinc with the highest concentration, followed by copper with average concentrations ranging between (0.587-0.814 µg/g wet weight), then lead (0.020-0.028 µg/g wet weight), while lead was (0.020-0.028 µg/g wet weight). Cadmium has the lowest concentration (0.025-0.014 µg/g wet weight), but all of these concentrations were within the limits permitted by the Food and Agriculture Organization of the World, and therefore they do not pose a threat to human health as the final consumer.
