Determination of Heavy Elements (Pb, Cd, Cu and Cr) Concentration in some Water Sources

Abstract

This study focuses on identifying some of the heavy and toxic elements concentration in several sources of water in Diyala Governorate in Iraq, such as the Diyala River and the Khіrisan River. The samples of tap water and bottled drinking water were taken three water wells from and two companies. The elements under study were: lead, cadmium, copper and chromium. Flame atomic absorption spectroscopy has been used to determine the concentrations. It was determined that copper concentrations are within normal limits and satisfy Iraqi and world health organization standards for drinking water, whereas the concentrations of lead, chromium, and cadmium are higher than the standard limits.
