Abstract

The current research included study seven a trace elements concentration (lead, cadmium, zinc, iron, manganese, selenium and nickel) in the fish Khushani muscles Liza abu Heckel collected from the Euphrates River , from Indian dam area for the period from October 2009 to September 2010, when the fish were divided into three categories (longitudinal and weight) . Also included a study of the concentrations of trace elements studied in water ( dissolved and particulate phase)  , and  also study of some physical and chemical properties of water river temperature of the air and water, and 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, Calcium, Magnesium and plant nutrients (nitrate and nitrite, phosphate), which variations depending on the heterogeneity of months studied . The results of the current study showed seasonal variations in the trace elements concentrations in both water phases (dissolved and particulate  phase) and in fish muscle . It was found that the concentrations of  trace elements in the third category was high compared categories of the first and second, results have found a direct correlation between the length and weight of the fish with the concentration of elements as elements of concentration increases with increasing weight and height. It was found that the concentrations of  trace elements studied the particulate phase were  higher than water soluble phase in addition to the effect of some physical and chemical properties of water such as pH and EC temperature and flow velocity and salinity on the concentration of trace elements studied.
