The concentrations of As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn was determined in the
muscle, gills, liver, and an intestine of the Clarias gariepinus from the Wadi Hanefah (WH), Saudi
Arabia. The accumulation of metals differed significantly (P<0.05) in the muscle and the skin. Zn
were most abundant (55.84±4.85μg/g dry weight) and Pb was in a minimum quantity (0.22±0.02
μg/g dry weight) in the muscle. The similar pattern of elemental deposition was observed in the skin
of C. gariepinus. The order of bioaccumulation of studied in muscle and skin of was Zn >Fe > Hg >
Cu > Se > Mn > Co > Ni >Cr > As > Pb. Fe was most abundant in proximal (682.21±12.52 and
695.60±8.35 μg/g dry weight) and distal (552.46±16.75 and 574.33±10.12 μg/g dry weight) sections
of liver in fish collected from upstream and downstream of WH, respectively. As and Cd was
recorded in minimum quantity as 0.72±0.28 and 0.61-±0.28 μg/g dry weight recorded in the
proximal and the distal section of liver, respectively. Fe was most abundant in proximal
(682.21±12.52 and 695.60±8.35 μg/g dry weight) and distal (552.46±16.75 and 574.33±10.12 μg/g
dry weight) sections of liver in fish collected from upstream and downstream of WH, respectively.
