The bioaccumulation of certain heavy metals: Co, Cu, Fe, Ni, and Pb in different organs: muscles, gills, ovary, and kidney of carassius auratus gibelio (Bloch,1982) caught from waters of Al-Hammar marsh, Southern part of Iraq, was studied using Atomic Absorption Spectrophotometry for the period Jan. 2016 to Dec. 2016, one cruse per month. Fe was found in high concentrations in all of the organs tested and throughout the seasons, with the largest concentrations occurring during the two winter months. Co and Cu were found in moderate amounts in the organs of Carassius auratus gibelio, although Ni and Pb were not. were the last to arrive. The gills and liver, on the other hand, accumulated the most heavy metals, while the muscles and ovary accumulated the least. The accumulation of heavy metals in the organs of carassius auratus gibelio fish from Hor Al-Hammar, Iraq's southern marshes, follows the Fe> Co > Cu > Ni > Pb trend. The results of metal concentrations in several organs of the fish Carassius auratus gibelio demonstrated that the Hor Al-Hammar marsh ecosystems are free of harmful metals Ni and Pb.
