| Abstract: This study was conducted to estimate the concentration of some Heavy metals, (cadmium, lead, zinc, iron, manganese, selenium and nickel) in the muscles of three different categories in the weight and length of fish Hamri Barbus luteus (Heckel) collected from the Euphrates River from Saddat- Al- Hindiya Region dam , during October 2009 to September 2010 . and estimated the concentrations of Heavy metals in river water ( dissolved and particulate phase) , And also study of some physical and chemical properties of water river temperature of the air and water, pH, Electrical Conductivity (E.C.) , Salinity, Speed of Flow, Dissolved Oxygen (D.O.), Biological Demand of Oxygen (B.O.D.) Total Suspended Substances, Total Dissolved Substances, Total Hardness and the Hardness of Calcium, Magnesium and plant nutrients (nitrate , nitrite and phosphate) , which were variety depending on the heterogeneity of months studied. The results of the current study showed seasonal variations in the concentrations of Heavy metals in both water phases (dissolved and particulate phase) and in three category of fish muscles . It was found that , the concentrations of heavy metals in the third category was high compared to the first and second categories , results have found a direct correlation between the length and weight of the fish with the concentration of metals as of metals of concentration increase as well weight and height . It was found that the concentrations of heavy metals studied in particulate phase were higher than water soluble phase in addition to the effect of some physical and chemical properties of water such as pH , EC , temperature , flow velocity , and salinity on the concentration of heavy metals studied.
