Abstract

In this research, the total concentration and morphological distribution of elements (Hg, Pb & Cd) in bottom sediments were determined within two study sites, the first site was Lake 16 Tishreen Dam and the second was the mouth of the Al-Kabir Al-Shamali River. The values of the total concentrations of the studied elements ranged as follows: Hg(1.58-0.25), Pb(28.45-6.22), Cd(5.69-0.85) (mg/kg). The highest values of these elements were recorded during the summer at the downstream site, while the lowest values were recorded. Values for concentrations during the winter at the dam site. As for the results of sequential extraction, the following values were recorded: the element lead was present in the highest percentage in the residual form (59.18%), while the percentage of its presence in the recoverable form recorded the lowest value (9.15%). As for the element cadmium, it was present in the highest percentage in the extractable form (43.56%) While the percentage of the traceable form was the lowest (15.24%), and finally, mercury concentrations recorded the highest values within the extractable form (55.35%), while the lowest percentage was within the residual form (4.87%).
