Abstract

According to the results of GC-MS study of the composition and distribution of hydrocarbons (n-alkanes, isoprenoids, steranes, hopanes, polycyclic aromatic hydrocarbons (PAHs) and their alkyl homologues), the genesis, facies conditions of sedimentation, the degree of transformation of organic matter of bottom sediments and marching soils of the southwestern coast of the Barents Sea are characterized. The assessment of the toxicity levels of polyarenes on the biota inhabiting the tidal zones of the coast was carried out. Areas with increased anthropogenic load have been identified (littoral of the eastern Tana Fjord, the village of Kiberg, Abram Cape, the village of Mishukovo, the mouth of the Kulonga River, the apex part of the Yarnyshnaya Bay, Oscar Bay), indicating the unfavorable ecological state of the tidal zones of the Barents Sea coast.
