Abstract
The composition and distribution of organic compounds in the bottom sediments of the Tom River near the city of Yurga (the Kemerovo Region - Kuzbass) in 1995, 2005 and 2018 are determined by gas chromatography - mass spectrometry. The compounds included hydrocarbons ( n -alkanes, isoalkanes, naphthenes, alkylbenzenes, and polycyclic aromatic hydrocarbons), oxygen-containing compounds (carboxylic acids and their ethyl and propyl esters). The data on the group composition of the most dangerous pollutants, polycyclic aromatic hydrocarbons, are presented. The pattern of changes in the technogenic load on the river system made by the Kuzbass enterprises over different years has been established. The highest contribution into the pollution of the Tom basin was determined to be in 2005. This contribution is directly due to the industrial activities at the enterprises of Kuzbass.
