This study aims to evaluate the concentrations of heavy metals (Lead, Cadmium, Manganese, Nickel, Zinc) in the muscle tissues of red coral fish (Pagellus erythrinus) traded in the markets of Tobruk. Twenty random samples were collected, prepared, and chemically digested according to the standard method (AOAC 999.10). Concentrations were measured using an Atomic Absorption Spectrophotometer (AAS). Statistical analysis (One-Sample t-test) revealed that the mean concentrations of Lead (0.756 mg/kg), Cadmium (0.139 mg/kg), and Manganese (4.678 mg/kg) significantly exceeded the permissible international limits set by FAO/WHO. In contrast, Zinc (5.412 mg/kg) and Nickel (0.037 mg/kg) were within safe limits. These findings indicate potential environmental pollution resulting from anthropogenic activities, which may pose a health risk to consumers. The study recommends caution regarding the heavy consumption of these fish and emphasizes the necessity of continuous environmental monitoring to identify pollution sources.
