ABSTRACT

The levels of 18 organochlorine pesticides (OCPs) and 6 metals in surface water and sediment samples from Danube River (Calafat-Turnu Magurele sector), Romania were investigated to evaluate their pollution potential. The total OCPs concentrations in water ranged between 3.1 and 12.8 ng/l and, in sediments, between 2.99 and 16.78 ng/g dry weight, respectively. In water and sediment samples, all the concentrations of investigated elements were below the maximum admitted concentrations, according to Romanian legislation, except for three Ni concentrations in sediments samples. HCHs, DDTs and heptachlor epoxide (components of the OCPs class), have recorded the highest concentrations in sediments. In water, the most dominant OCPs were γ-HCH among HCHs, and 2,4’-DDE, among DDTs.
