Concentrations of some heavy elements in fly ash samples from thermal electric power stations in the middle and south of Iraq

Abstract

The objective of this present work is determining some heavy elements concentrations like (Cd, Co, Mg, Mn, Fe, Cu, Ni, Pb & Zn) in thermal electric power stations in the middle and south of Iraq. 18 Fly Ash samples were collected from thermal electric power stations in the middle and south of Iraq ,the concentration values of (Cd, Zn , and Fe ,Mg, Cu) in some samples were over the international limits in the Fly Ash samples .In general the increasing of the heavy metals in some fly ash samples due to the releasing of these metals is the combustion of the fuel and fuel type which provides thermal electric power station different from units to other , and geology of the region collected samples from it and the geochemical characteristics of the crude oil.
