Topsoil samples (0-20 cm) were collected from the sediments of Euphrates River in September,2011.Total concentrations of five heavy metals, cadmium (Cd), copper (Cu), iron (Fe),manganese(Mn) and zinc (Zn) were determined using atomic absorption spectrometry in order to assess their contaniination levels of the sediments . Four stations were chosen in the Euphrates at Nasiriya city. Results showed that the average concentrations of these heavy metals in the sediments were signifioantly higher than those previous and similar studies. But the present study indices showed no contamination for Mn, and Zn, in all samples. Location variations were detected in this metals.The highest concentration of Cd was(38μg/g) and the lowest (15μg/g) were recorded in sta.3,4 respectively , Cu revealed the highest cone. 416 μg/g at sta.3. The lowest (317μg/g) was recorde8d in sta.l.The highest cone, of Fe was encountered in sta.2 (384μg/g) ,while lowest values were recorded from sta.l was (840 μg/g). Mn showed increments in sta.3 (370 μg/g). and the lowest values were recorded in stas.l was (327μg/g). Similarly, the highest cone, of Zn were recorded sta.2(96 μg/g)and lowest was (84 μg/g)at sta. 1.The study showed that pollution with some of this metals compared with global standard request watching period and continue test in regular periods .
