I.A. Nemirovskaya. Anthropogenic and natural hydrocarbons in the ecosystem of the White Sea // The study, sustainable use and conservation of natural resources od the White sea. Proceedings of the IXth international conference October, 11-14, 2004, Petrozavodsk, Karelia, Russia, 2005. Pp. 244-248
New data for content and composition of hydrocarbons (HC), aliphatic and polycyclic aromatic hydrocarbons in water, suspended matter (collected by Jede net, 50 чm, and with the help of onboard separators) and bottom sediments of the White Sea are discussed. It is found that HC concentration in the White Sea waters (18 чg/l on average) has remained virtually unchanged during the last years, and is comparable with their average concentration in shelf areas of the World Ocean. Marginal river filters govern HC distribution in water and bottom sediments. Great bulk of anthropogenic HC is deposited in this area. Therefore a factor of granulometric control disappears in river depocentre zones (in Northern Dvina River particularly). Most likely the same reasons can explain distinctions in a degree of geochemical couplings between Corg and HC contents in suspended matter and bottom sediments. Natural HC prevails in all migrating forms after marginal river filters passing through.
