The aim of this work was to establish the level of pollution by highly persistent polychlorinated contaminants in sediments from the Vistula Lagoon. Concentrations of PCBs, DDT and its metabolites, isomers of HCH and HCB were determined in the surface sediments (0 - 3 cm depth) from 6 stations. All the substances investigated were present in sediment samples from the Vistula Lagoon in concentrations above the detection limit of the method used (0.01 ng?g-1 d.w.). Concentrations of isomers of HCH and HCB ranged between 0.04 and 0.33 ng?g-1 d.w.. PCB values varied from 0.10 ng?g-1 d.w. to 0.99 ng?g-1 d.w. Of all the substances analysed, DDT and its metabolites were present in the highest concentrations - up to 1.97 ng?g-1 d.w.
