The present study was conducted to investigate the presence of some heavy metals in Euphrates River which is considered the largest river in Iraq at Thi-Qar provinces south of Iraq. The river receives most of the wastewater including industrial, agricultural, and domestic wastewater from many cities. Eight stations were chosen along eight km at each side of the river from the period March 2015 to January 2016. The concentrations of some heavy metals (Zn, Cu, Pb & Cd) in water monthly in addition to pH, electrical conductivity, dissolved oxygen and total organic carbon (TOC%) , in order to effectively monitor and provide possible recommendations to improve the water quality in the aquatic ecosystem of Euphrates River. The results showed the mean concentration of Cu, Zn, Pb and Cd, in water were (6.08), (1.75), (5.6) and (0.31) µg.l-1 respectively. The general concentration order of the studied metals in the river water was: Cu > Pb > Zn> Cd, and the average of total organic carbon (TOC%) was 0.016 %. Monthly variations were observed in the mean concentrations of the studied metal ions in water. The results also showed that there is a distinct variations of the (TOC%) being lower in all stations during summer and becomes higher in winter.
