Evaluation of Some Heavy Metal Levels in Tissue of Fish Collected from Coasts of Susa Region, Libya

This study aims to estimate the levels of various heavy metals (Zn, Cu, Pb, Co, Cd, and Cr) in different tissues of fish samples collected from various locations along the Libyan coast. The fish species included in the study were Siganus rivulatus, Mugil spp, and Mullus barbatus. The metal concentrations in the studied fish samples were found to follow this order of abundance: Zn> Pb> Cu>Co. The detected metal concentrations varied as follows: (56.74 - 141.52 ppm), (29.74 -101.84 ppm), (51.33-111 ppm),(3.19-5.03 ppm),(1.60-1.93 ppm), and (1.26-33.60 ppm). These variations in metal concentrations are attributed to differences in the activities and metal sources in the various sampling locations. The accumulation of metals in the fish samples suggests that these species could potentially serve as bioindicators of heavy metal pollution
