The seasonal study of heavy metals were taken during February 2018 to November 2018. The concentration of heavy metals were determined(Cd, Cr, Cu, Zn, Ni, Pb, Fe), by using Flame Atomic Absorption Spectrophotometer (FAAS) for sediment sample at Ten stations along Al-Delmaj Marsh they are (St.1, St.2 before water recharge, St.2 after water recharge, St.3, St.4, St.5 before water discharge, St.5 after water discharge, St.6, St.7, St.8), the stations were selected to cover all the marsh area. The Total Organic Carbon (TOC%) were analyzed. The results obtained for the sediment samples were low except for Fe and Pb which were relatively high. Which were followed the order : (Fe >Pb>Zn> Ni>Cr>Cu> Cd).Whereas the highest mean also the lowest mean concentration in some stations because of the fewness sources of pollution in this region whereas the highest mean concentration in other stations because of there are a lot of pollution sources such as: (sewage pollutants, municipal waste, and fertilizer waste). there is a variation in the concentrations of studied elements they were ranged as follows: Cd: (0.222 - 0.283 μg/g), Cr: (1.472 - 1.685 μg/g), Cu: (0.305 - 0.362 μg/g), Zn:(1.947 - 2.826 μg/g), Ni: (1.738 - 2.206 μg/g), Pb: (3.696 -4.921 μg/g), and Fe: (10.95 - 13.247 μg/g), The concentrations of heavy metals are very importance to know the locations of pollution, its percentage and causes, sources and methods of treating pollution to preserve public health. The rate of Total Organic Carbon in the studied area were ranged (0.55- 0.97), and this indicates the influence of sediments in the presence of a source of organic materials, due to the degradation process that occurs in the area sediments
