Abstract

During spring and summer (2014) environmental investigations of the sea coastal zone, conducted in the frameworks of the Baltberegozaschita (Kaliningrad) program, determinations of content of heavy metals and oil products in the bottom sediments along the shore of the northern coast of the Kaliningrad Region were performed. The highest values of their contents were found in the middle part of the Curonian Spit (near the border with Lithuania). According to Swedish classification WGMS 2003-SSQC these values correspond to the highest 4 and 5 Classes of Contamination. At the Curonian Spit, which is a protected area, unknown any significant sources of anthropogenic pollution. Supposedly, the origin of the detected anomaly is connected with influence of along shore bed load, directed from abrasive coast of the Sambia Peninsula along the Curonian Spit, to its middle part, where accumulation of sedimentary material is dominated. The shore of the Sambia Peninsula is much more populated and used for recreational purposes, and can therefore be considered as a possible source of contamination.
