A study was carried out on the pollution of sea water in the eastern part of the Vostok Bay through organic matter (petroleum hydrocarbons, detergents, ASSAS (= anionic synthetic surfaced active substance), BOD5) in the warm period of 2016–2018 in the proposed sites of the marine terminal petrochemical complex and the release of plant wastewater. The results of hydrochemical monitoring indicate pollution of the Bay by petroleum hydrocarbons at a level of up to 7 MPC, 1.3 MPC for phenols, 1.6 MPC for ASSAS. A comparison with the literature data suggests that for the period from 2008 an increase in the anthropogenic load on the waters of the Vostok Bay has occurred, which is associated with an increase in the recreational press to the water area of the Bay.
