In this study a certain chemical elements Cu, Mn and Pb were determined in water, and another set of Cd, Cu, Fe, and Zn were determined in sediments from selected sites (1) Qurnah, (2) Al-Noor Bridge, (3) Saad Bridge, (4) Sindbad Island, (5) Al-Ashar, (6) Abu Al-Khaseeb, (7) Seebah, and (8) Al-Faw along the Southern Iraqi water ways during the year 2015. Low levels of heavy metals were recorded in the water of Shatt Al-Arab river, they were in the range 0.00735 - 0.02090, 0.00505 - 0.02145, and 0.00150 - 0.0837 µg/l for Cu, Mn, and Pb respectively, and lower values recorded were for the toxic Pb metal. On the other hand levels of heavy metals in the sediments were little bit high and in the range 0.1172488 - 0.614806, 17.175343 - 40.156639, 8156.970 - 21021.63, and 31.864781 - 79.160779 µg/g dry weight for Cd, Cu, Fe, and Zn respectively. Fe recorded the highest levels of heavy metals in all sites due to the nature of the sedimentary valley in Iraq. Low levels of heavy metals Cu, Fe, and Zn were recorded in the sediments of Seebah (site no.7) due to the effect of sediment movements through Karun River from the Iranian territories. More over levels of all investigated heavy metals were recorded high values in the water from Ashar (site 5) due to corrosion of marine vessels sunk in the area since the Iraqi-Iranian War 1980-1988.
