Investigation of Heavy Metals Pollution in Euphrates River (Iraq) by Using Heavy Metal Pollution Index Model

Abstract

This study aims to investigate heavy metals (HMs)pollution in the 'Euphrates' river which is located from Al-Kifl city to Kufa city, in Iraq. We analyzed six heavy metal parameters (Cd, Pb, Zn, Cr, Fe, and Mn ) in water, every month several samples were taken from six sites on the Euphrates river and covered the period of time from July 2020 to January 2021. Heavy metal analysis results were assessment according to the values of the maximum given in Water Quality Regulation. The obtained outcome of the analysis revealed that cadmium values surpassed the limit values for sites 1 and 5. The overall pollution level of the HMs pollution index model appeared to be helpful to Evaluate with respect to HMs and the values were found higher than the critical pollution index is100 in site 1.
