The presented results include decade of monitoring of the Vistula Lagoon waters and have been supplemented by the determination of chlorinated compounds, as well as on concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in the sedimentation zone. Monitoring of river waters entering the Polish part of the lagoon and the lagoon waters confirmed the presence of plant protection chemical; the largest contributors has lindane (34%) and DDT total (21%); the same as for sediments were dominate lindane (19%) and DDT total (14%) within pp-DDT isomer dominate (13%). In the lagoon water, PCDD/Fs were determined within a range of 1.5-5.6 ng dm -3 , leading to average toxicity of 0.18 ± 0.13 ng TEQ·dm -3 . In sediments, their concentrations fell within a range of 22.7-405.7 ng kg -1 dw and the average toxicity of the lagoon sediments was set at 5.00 ± 1.98 ng TEQ·kg -1 dw. Both in water and sediments, the greatest share among PCDD/Fs has octa-chlorodibenzodioxin. Due to the hydromorphological conditions of the lagoon, the waters are mixed to the bottom causing the surface layer of sediment to become remobilized-this is suggested as the key factor when it comes to water recontamination and increased access of POPs to marine organisms. |
