Abstract
In this work, analysis of bottom sediments (BS) samples and columns was conducted for the total content of petroleum products (hydrocarbons) of the Norilo-Pyasinsk group water reservoir, which were contaminated as a result of JSC NTEK CHPP-3 reservoir diesel spill nearby Norilsk. Processing two analysis methods used: fluorometric and gas chromatographic, meanwhile in addition the n-alkanes distributions of obtained BS extracts with gas chromatography were studied, the contribution of the total hydrocarbon content in diesel fuel so as hydrocarbons of slightly mature organic matter in contemporary sediments. Determination hydrocarbon composition of BS diesel fuel and chloroform extracts was processed. As a result, the levels of BS pollution by hydrocarbons for Pyasino Lake appeared insignificant with their background content comparison, and the maximum pollution revealed for the Ambarnaya River BS.
