Assessing the Sediment Pollution using Heavy Metals Indices in the Nile River Branches in Egypt
Y.A. El-Amier*, A.M. Abd El-Gawad

Nile river is the main source of fresh water in Egypt. It extends from Aswan to its estuaries at Damietta and Rosetta cities on the Mediterranean coast. The present study aimed to assess some heavy metal pollutants in the hydrosoils of the two Nile river branches (Damietta and Rosetta). Twenty sites were chosen for each branch, Fe, Mn, Zn, Cu, Pb, Ni, Cd and Co were measured in the hydrosoil. Different heavy metals indices (Enrichment factor, contamination factor, degree of contamination, ecological risk index and geo-accumulation index) were calculated. The results showed that Rosetta branch is more polluted than Damietta branch. Heavy metal indices give an indication for the pollution of the sediments of both branches with Cd which considered as carcinogenic element when its uptake in the food chain increases. The enrichment factor showed that the source of those metals in Nile river branches was from the anthropogenic activities. Cu, Zn, Ni, Pb and Co showed low ecological risk factor in all sites of both branches. The ecological risk index ranged between low, moderate to considerable in most of the studied sites of two branches. It is urgent need for pretreatment of different waste water before discharge in the Nile river.
