الملخص EN

The determination of trace metals (Cd, Pb, Mn, Zn, Cu, Ni and Fe) in three locations Al- Mushab , Al-Nagarh and Al-Bourgah , of southern part of Al-Hammar marsh in 2009 during both the dry period ( March , April and May) and the wet period (September , October and November) , were achieved by means of Flame Absorption Spectrophotometer were determined in sediment samples .The result showed that the Al-Mushab as the most contaminated site with Zn and Pb, Al-Nagarh as the lowest contaminated with all metals while Al-Bourgah as the most contaminated with Cd , Co, Cu, and Ni .The concentrations of trace metals are effected by chemical and physical parameters .The contamination with trace metals may determined to the health of the aquatic ecosystem and the rural communities that utilize the marsh water for domestic purposes without any treatment .The sediment pollution with heavy metals through to be due to different sources such as urban wastes , industrial effluents , land washout and boats activities.
