“…Водные объекты в зонах повышенной антропогенной нагрузки подвержены различным видам загрязнений [1], включающих тяжелые металлы, полициклоароматические углеводороды (ПАУ), полихлорированные бифенилы, диоксины и хлорорганические пестициды [2][3][4][5][6], нефть и продукты ее переработки [7][8][9]. Большое количество загрязняющих веществ со сточными водами в результате разливов нефти, муниципальных и промышленных сбросов, а также автомобильных отходов и выбросов автотранспорта из-за неполного сгорания ископаемого топлива переносятся речными водами через устья рек в море [10].…”

The composition of organic component of water and bottom sediments of Ob River in the area from the mouth of Tom River to the mouth of Irtysh river was studied by using GCMC. Oil and biogenic compounds were found. The maximum content of biogenic compounds was obtained in water near the Vasyugan River mouth, which is starting and flowing through the area of peat bogs propagation. The latitudinal waters of Ob River are enriched with typical oil compounds, such as hopanes, steranes, secohopanes, cheilanthanes, tetracyclic aromatic hydrocarbons, polymethyl substituted naphthalene and phenanthrene. The bottom sediments near the inflow of Tom River are enriched with polycyclic aromatic hydrocarbons. It was shown, that the occurrence of n-alkanes with dual nature cannot be an indicator of water bodies pollution with crude oil. In addition to this, the composition of aromatic hydrocarbons and cyclic isoprenoids may be used to differentiate the pollutant sources

The paper has deal with the monitoring of the lake bottom sediments which were contaminated by oil during emergency spill. The results of geochemical study of chloroform bitumoids extracted from sediment samples showed that the processes of transformation of oil hydrocarbons lasted for 10 years since the oil spill. This is indicated a decrease in the residual oil content and changes in the chemical composition of bitumoids. The hydrocarbons content was decreasing and resinous-asphaltene components was increasing as oxygen-containing groups and bonds in the chemical structure of bitumoids. In the individual composition of hydrocarbons the significant redistribution of saturated hydrocarbons was occurring both within the homologous series and between different homologous series, the CPI coefficient and the biodegradation coefficient Prophy/nC17+nC18 was increasing. By 2017 in absence of new oil spills the chemical composition of bottom sediments had closed to a state inherent in the native organic matter of bottom sediments of coastal lake facies, which characterized by the presence of compounds typical for higher plant lipids (dominance of high molecular weight n-alkanes of composition nC23–nC33 with a significant predominance of odd homologues, a high content of oxygen-containing compounds – solid saturated fatty acids, aliphatic esters and saturated ketones).
