Abstract

The concentrations of nine heavy metals (Cr, Cd, Pb, Ni, Cu, Zn, Mn, As and Fe) in the muscle tissue of four fish species (Oreochromis niloticus, Clarias gariepinus, Poecilia latipinna and Aphanius dispar dispar) collected from Wadi Hanifah were detected in two different seasons. The concentrations of the studied heavy metals, except for Cd, Pb, Ni and Cu in A. d. dispar and P. latipinna, were found to be below the safe limits recommended by various authorities and thus provide an indication of the extent of pollution of these metals. The present study also demonstrates that Zn and Cr were the most and least accumulated metals, respectively, in the studied fish muscle tissues. From the standpoint of human health, this study suggests that there is a possible health risk to consumers due to the current consumption rate of A. d. dispar and P. latipinna in Saudi Arabia.
