Tishreen University Journal for Research and Scientific Studies - Basic Vol. ( ) No. ( ) Distribution of Some Traces of Heavy Metals in AL-KABEER AL-SHEMALY Estuarine Sediments Dr. Seif Eddin Noureddin * Dr. Ghiath Abbasse** Osama Abdo*** (Received / /. Accepted / / ) ABSTRACT We study in this paper the distribution of some traces of heavy metals (Cu, Cr, Cd, Fe, Mn, Ni, Zn & Pb) in the sedimentary phase of Al-Kabeer Al-Shemaly river estuary, and the principal factors affecting this distribution. Our results show a large decrease of sedimentary Cu and Mn with transition from river sector to marine sector of estuary zone (with increasing salinity), while this decrease is disparate for other metals. Sedimentary concentrations of metals were higher in summer than in winter. The results confirm a good correlation between Pb concentrations and other metals concentrations. On the other hand, there was a similarity in the behavior of (Cr, Cu, Fe, Mn, Pb & Zn) with transition from river sector to marine sector of estuary zone.
