Analysis of Heavy Metals in Water Samples of Euphrates River in Nasiriya City, Iraq

Water samples were collected from the water of Euphrates River in September, 2011.Total concentrations of four heavy metals, Cadmium (Cd), Nickel (Ni), Chromium (Cr)and Lead (Pb) were determined using atomic absorption spectrometry in order to assess their contamination levels of the Water. Four stations were chosen in the Euphrates at Nasiriya city. Results showed that the average concentrations of these heavy metals in the water were significantly higher than those similar global studies. Location variations were detected in this metals. The highest concentration of Cd was (38µg.L-)at sta.3 and the lowest (15µg.L-) were recorded in sta.4 respectively , Ni revealed the highest conc. )416 µg.L-( at sta.3. The lowest (317µg.L-) was recorded in sta.1.The highest conc. of Pb was encountered in sta.2 (370µg.L-) ,while lowest values were recorded from sta.1 was (327 µg.L-). Cr showed increments in sta.2 (884 µg.L-). and the lowest values were recorded in sta.1 was (420µg.L-).The study showed that pollution with some of this metals compared with global standard request watching period and continue test in regular periods
