Six observation sites were chosen from Tigris River for Baghdad City to know the pollution with major, minor and trace elements (physical and chemical properties). The study depended on 24 variables in two periods, first in January and the second in April from water year 1999-2000 to show the characteristics of pollution and the effect of embargo on this water resource. The results reflect that higher concentration in some elements when we compare the results with previous study especially in SO4, Fe, Ni and Cd, so we must put suitable plans to stop this deterioration in the environment of Tigris River.
