This study including determination the concentrations of eight heavy metals ( Pb, Ni, Co, Cr, Zn, Co, Cd and Fe) in exchangeable and residual phase by using Flame Atomic Absorption Spectrophotometer (FAAS) for sediment core at six stations along Shatt Al-Arab estuary they are: ( Al-Qurna, Al-Deer, Al-Qarma, Al-Ashar, Abu-Alkasib and Al-Fao ). The Total Organic Carbon (TOC%) and Grain Size were also analyzed. Recent fauna has been Diagnosed in these core samples, we found Foraminefra , Ostracoda and a lot of Mollusca with deformation shell Indicating influenced by Heavy metals pollution therefore it could be used as pollution indicator.
