Abstract
The distributions of bioorganic components, as well as compounds of anthropogenic and mixed origins, have been studied in the sediments and water of the Parshikha Bay of the brackish Lake Chany (the Novosibirsk Region). The contribution of the main sources of organic matter in water and bottom sediments was estimated relying on the compositions of identified compounds (acyclic, aromatic and naphthenic hydrocarbons, acyclic and alicyclic oxygenated organic compounds, steroids, bicyclic sesquiterpenoids and pentacyclic triterpenoids). The composition of these objects has been established to be formed mainly due to the compounds of biogenic and mixed origin. The ratio of odd to even alkanes is equal to unity, the presence of cyclohexanes and drimanes, which are not characteristic of recent precipitation, indicates the presence of petroleum products. Household compounds - triphenylphosphates and phthalates, which are used as plasticizers in the production of polymer materials, have also been identified.
