Abstract
The distribution of natural and anthropogenic components, and also compounds of mixed origin in sediments of lakes in Southern Siberia, and also Altai steppes and mountains characterised by a varying degree of mineralisation (between 0 and 300 g/dm3) was explored by gas chromatography-mass spectrometry. The contribution of the major organic matter sources to the composition of bottom sediments was assessed. Specific oil compounds were determined. As determined, there was the formation of the composition of bottom sediments mainly due to compounds of biogenic and mixed origin. Sections with a high content of pollutants, such as petroleum and pyrogenic hydrocarbons, and also isoalkylbenzenes, i.e., likely degradation products of surfactants, were detected.
