Abstract:
Contents and distribution of particulate lipids were studied by thin-layer chromatography technique with flame ionization detection (Iatroscan TH-10) along the transect from the Ob River towards the Kara Sea. Lipid contents range from 18.4 to 266 µg/l with, average 84.97 µg/l, which comprises from 4.06 to 58.32 % of total particulate organic matter. Principal constituents of particulate lipids are hydrocarbons (32.14 % of total lipids on the average), polar compounds (29.85 %), wax and sterol esters (13.04 %), and mono- and diglycerides (12.52 %). Secondary components are presented by fatty acid esters (5.14 %), free fatty acids (4.56 %), triglycerides (2.32 %), and sterols (1.04 %). Specific composition of particulate lipids along the Ob River - Kara Sea transect is formed under strong impact of river run-off. Particulate lipid composition reflects differences between processes of organic matter transformation in estuarine and marine parts of the transect, as well as peculiarities of species composition of Arctic living organisms.
