“…Some water runs into the Curonian Lagoon from the Baltic Sea. The Nemunas River, with its main delta arms the Atmata and the Skirvytė as well as some smaller channels, are the main sources of water and sedimentary material to the lagoon (Emelyanov et al, 2015). Before water flows into the Baltic Sea, a large portion of heterogeneous sedimentary material mobilized from the land migrates with the surface waters of the Curonian Lagoon and gradually gets deposited on the bottom of the lagoon (Galkus, Jokšas 1997;Jokšas et al 2003).…”

Samples of surface (0–3 cm) bottom sediments of the Lithuanian aquatic area of the Curonian Lagoon and Nemunas River delta were taken from 41 sites in 2013 and 2014. Sediment parameters, such as the percentage of particles, concentration of organic carbon and heavy metals (Cu, Zn, Ni, Pb, Cr, Cd, and Hg), were determined. The heavy metal contamination of the surface layer of bottom sediments was determined using the Nemerov’s pollution index applied to soil. The spatial distribution of contamination indices and the dependence of contamination dynamics on sedimentation factors were analysed. It was determined that heavy metal concentrations had a tendency to increase as sediment particles became finer and as Corg concentration increased. A greater amount of pollutants got into the aquatic area of the Curonian Lagoon that was closer to the Klaipėda harbour than into other lagoon zones. The heavy metals for the integral pollution index for the Curonian Lagoon and Nemunas River delta surface bottom sediments could be arranged in the following order: Cd>Pb>Cu>Ni>Hg>Cr>Zn.
