The result showed that the values of cadmium ion were 0.0346 ug/L to 0.0707 ug/L. The Lead values of the Tigris River water samples were 4.29 ug /L to 8.33 ug /L. The values of nickel ion have been ranged between 7.59 ug/L to 9.75 ug/L. Zinc ions have been recorded 53.5 ug /L to 72.1 ug /L. The concentration of above ions was situated within Iraqi and world Health organization (WHO) criterions that relating with propriety of water of Tigris River for drinking and irrigation.
