Abstract
The distribution of bioorganic components and compounds of anthropogenic and mixed origin in the bottom sediments (BSs) in freshwater Lake Chyornoye and saltwater Lake Tus (Republic of Khakassia) has been studied using the chromatographic mass spectrometric method. The contribution of the major organic matter sources to the BS composition is assessed. It is ascertained that the formation of the BS composition can mostly arise due to the compounds of biogenic and mixed origin. Some lake sites with elevated concentrations of pollutants—petroleum and pyrogenic hydrocarbons and iso-alkylbenzenes as the probable degradation products of surface-active agents—are identified.
