AbstractConcentrations of cadmium, cobalt, cupper, iron, manganese and nickel were determined in four organs (skin, ovaries and muscles) of Liza abu, which belong to family of Mugilidae collected from Al-Razazah Lake. Heavy metals have been determined by means of Atomic Absorption Spectrophotometer. The fish average weight was 69.7g and the average length was 200 mm. In muscles, iron showed the highest value (91.98μg/g dry weight), while cadmium has been not detected in Atomic Absorption spectroscopy. This study showed that the concentration of heavy metals distributed in the organs was as follows: liver > gills > muscles > ovaries, while the total heavy metals concentration had been distributed as follow: iron > cupper > nickel > manganese > cobalt> cadmium.
