Benthic communities and habitats in the near shore zone of the Curonian Spit (the south–eastern part of the Baltic Sea)

Abstract

Data regarding the content and composition of the hydrocarbons (HC) — aliphatic hydrocarbons (AHCs) and polycyclic aromatic hydrocarbons (PAHs) — are presented in comparison with the content of the total organic carbon (Corg) in the bottom sediments in the coastal area of the eastern part of the Gdansk Basin (Russian sector of the Baltic Sea). The HC and PAH distribution in the sediments confirm the dependence of hazardous substance accumulation on the organic carbon content and the sediment grain size of the affected sediment. Bigger concentrations of PAHs were also observed near the Pionersky port. Particular attention was paid to the PAHs content.
