Assessment of heavy metals pollution in the sediments of Haditha reservior and Eupheates River, within Anbar Governorate/Iraq

Abstract

10 sediment samples were obtained from Haditha reservoir and Anah city in Al-Anbar governorate for this study during (October, 2021). to assess sediment contamination in trace metals like (Cd, Fe, Pb, Zn, Cu, and Ni), from applying geochemical contamination coefficients such as Geo - Accumulation variable I-Geo, Contamination Factor CF, as well as Pollution loud Index PLI. The research area is found in the northwestern region of Al-Anbar governorate, between the longitudes (42º23'.13'' - 42º01'.10'' E). and latitudes (34º10'.22'' - 34º22'.7'' N), The area which is located between Haditha Dam and Anah city. The results of geochemical analyzes showed that it soil sediment has a high value of the elements (Ni, Fe and Cd), which exceeds the limits of local studies, this can be affected by Anthropogenic activities like urbanization, industrialization, agricultural runoff, fertilizers, and also the Haditha dam's electrical station, but the elements (Zn, Pb and Cu), Within the permissible limits of local studies.The results of the I-geo shows that the elements (Ni, Zn, Pb, Fe and Cu), has unpolluted (class- 0). While Cd is (class- 1), slightly polluted. The Contamination_Factor CF to (Fe, Ni) was characterized since (classes- 2), moderate pollution. But even so, (Zn, Pb, and Cu) were characterized as (classes- 1), small contamination. As for the last element (Cd), classify as (classes- 3), Considerable contamination. While the Pollution Load Index PLI to (Cd, Fe, Pb, Zn, Cu, and Ni),has been calculated and characterized as (classes- 2),Deterioration site. Except for (S1-S2 wet and S2 dry), which is characterized as (classes- 0), Perfection. The principal purposes of this reseaech are to evaluate trace elements contamination within the research site's soils.
