Concentrations of copper, cadmium, cobalt, manganese, nickel, and lead in the muscles of freshwater fishes, crassius crassius, aspius vorax and barbus luteus colleted from Alhammar Marsh (South of Iraq)‎

الملخص EN

To assess the significance of metals in fishes from Al-Hammer marsh (South of Iraq), preliminary data is presented on concentrations of Cu, Cd, Co, Mn, Ni and Pb in tissues of three fresh water fishes (Crassius crassius, Aspius vorax and Barbus luteus) collected in 2006-2007 seasonally period.

Copper range from Below detection limit (BDL) in B.

luteus tissues for all sampling seasons to 4.

12 (μg / g.

dw) in the muscles, for Cd, Co and Ni were range between BDL to 24.

49 Cd, 4.

86 (μg / g.

dw) in all tissues and 88.85 Ni (μg / g.

dw) in the A.

vorax and B.

luteus muscles respectively.

Metal concentrations seemed to be increased through hot periods (Summer and Spring) compared with cold periods (Autumn and Winter), During data analyses, C.

crassius tend to accumulate more concentration of all study metals than A.

vorax and B.

luteus.
