A survey of a typical small reservoir in the Leningrad region of the eutrophic type, used for sport fishing, has been carried out. Gas chromatography-mass spectrometry revealed the presence in the lake water of hazardous, highly toxic for the fish population and aquatic organisms, compounds of organophosphorus pollutants triphenyl phosphate (TP) and cresyl diphenyl phosphate (CDP) with concentrations of 0,0164 and 0,0037 mg/dm3. The detected concentrations of TFF and KDF are higher than the predicted regional concentrations of these compounds for surface waters, which indicates the need to monitor the spread of these substances, as well as other dangerous organic pollutants, in the reservoirs of the Leningrad Region and St. Petersburg, where they can enter as a result of intensive economic activity in the adjacent territories.
Key words: gas chromatography-mass spectrometry, triphenyl phosphate, cresyl diphenyl phosphate, water bodies of the Leningrad region, monitoring, phytoplankton, bacterioplankton, total phosphorus, oxygen concentration, sport fishing
