The relationship between concentrations of some trace elements in the Euphrates River of Iraq

Abstract

This study was conducted to measure the concentrations of some trace elements (lead, cadmium, cobalt, iron, and nickel) for the waters of the Euphrates River in three locations of Al-Hindia, Al-Kifl, and Kufa. The study included measuring some physical and chemical properties of river water and their rates were as follows: Air temperature 16-42 °C, water 14-37 °C, pH 7.1-8.2, electrical conductivity 740-1250â μSiem and salinity 0.45-0.79. The study results for trace elements which dissolved in water were as follows lead in the soluble form ranged between 0.63-1.37, 0.51-1.93 and 0.26-1.51â μg/L in Al-Hindia, Al-Kifl and Kufa respectively, while the soluble cadmium showed that the values ranged between 0.06-0.53, 0.12-0.616 and 0.06-0.67â μg/L in Al-Hindia, Al-Kifl, and Al-kufa, respectively, and the results also showed that the values of melted cobalt ranged between 0.07-0.90, 0.06-1.26 and 0.02-1.25â μg/L. As for the iron, the results showed that the values of dissolved iron ranged between 0.59-1.75, 0.42-2.57 and 0.34-1.35â μg/L in Al-Hindia, Al-Kifl and Kufa respectively, while the values of melted nickel ranged between 0.11-1.43, 0.29-1.67 and 0.13-1.22â μg/L in Al-Hindia, Al-Kifl and Kufa respectively. It was found from the current study that the rates of concentrations of trace elements in water and in soluble form and for the studied Al-Hindia locations, Al-Kifl and Kufa were as follows: Iron
