Abstract

This study aim to estimate bioaccumulation of some metals (Cr, Mn, Fe, Cu, Zn and Pb) in different fish tissue (skin, Muscle, liver and gills) of Dicentrarchus punctatus. The samples were collected from local supermarket in Misurata city, Libya in summer, 2017. Tissue of this study was analyzed by atomic absorption spectrophotometer (AAS) to find the concentration of heavy metal (mg/kg). The results showed that the mean concentration of Zn was higher than Pb in skin, gills. Furthermore, Fe, Zn and Mn were higher in muscle than liver, except Cu and Zn their concentrations were higher in liver. While low concentration of Pb in all study organs.The order of metals in liver, gills, skin and muscle samples were found to be Cu > Fe > Mn >Zn >Cr = Pb;  Fe > Zn > Cr >Mn >Cu >Pb; Fe >Zn >Mn >Cr = Cu >Pb respectively. Some levels of metals (Cr and Fe) in this study were higher than the maximum permissible limits of FAO and WHO for human consumption.
