Resumo: |
The concentration of seven heavy metals (Cd, Cu, Fe, Mn, Ni, Pb and Zn) were detected seasonally in muscle tissues of two fish species (Siganus rivulatus, Sargus sargus) collected from El-Mex Bay and Eastern Harbour. In both species, levels of the seven metals were significantly higher in summer compared with other seasons. The concentrations of such metals decreased in the order Fe > Zn > Cu > Ni ≥ Pb > Mn > Cd. The metal pollution index (MPI) for the two species fluctuated between 0.9 and 1.8 in El-Mex and Eastern Harbour. Provisional Tolerable Weekly Intake (PTWI) demonstrates that the concentration of the metals (Cd, Cu and Pb) in the muscle of Siganus rivulatus and Sargus sargus from El-Mex Bay and Eastern Harbour are much lower than the PTWI values and accordingly there is no risk for the human consumption of these fish species.
