Doctor habil. (Chemistry), Leading Researcher of the N.N. Semenov Federal Research Center for Chemical Physics, Russian Academy of Sciences, Moscow, Russia, specializing in biophysics, environmental protection (1992).  

Highly qualified specialist in the field of oxidation-reduction and photochemical processes in the aquatic environment, as well as in the field of toxicological control of natural, drinking and waste water. Doctoral dissertation of E.V. The paper is devoted to oxygen-dependent oxidation-reduction processes in natural waters and biological systems, development and practical use of methods for assessing and managing the quality of the natural aquatic environment.

Research interests:

• development of complex generalized indicators of the quality of the natural aquatic environment for various types of water use;
• study of the possibilities of their use in the practice of solving water protection problems;
• implementation of toxicometric control methods for the greening of technological chemical processes, as well as when using pesticides and agrochemicals in agricultural production;
• application of biotesting methods to monitor the safety of aquatic systems.

Main scientific results:

• Sensitive methods for determining low concentrations of hydrogen peroxide in aquatic environments (detection limit 10-7M) have been improved, which made it possible to develop generalized indicators of the quality of the natural aquatic environment, as well as to identify a new natural phenomenon that arose as a result of complex anthropogenic impact on aquatic ecosystems: the formation of a "quasi-reductive" state of the aquatic environment, toxic to aquatic organisms;
• It was established that the "quasi-reductive" state is realized when intensification of intra-reservoir recovery processes involving water-soluble substances that effectively interact with H2O2 and are inert with respect to O2. The conditions leading to intensification of recovery processes involving blue-green algae in municipal and industrial wastewater subjected to aerobic treatment in aeration tanks, as well as in bottom sediments in reactions involving H2S and Fe(II) ions, have been identified and studied;
• A new natural phenomenon has been discovered during intensification of free-radical processes as a result of latent low-intensity contamination with radionuclides. Against the background of increased manganese ion content in water, a toxic "super-oxidative" state can form, leading to the death of adult fish and toxication of drinking water sources in areas subject to radiation and chemical contamination. Carriers of superoxidative equivalents are microcolloidal (nano)particles of Mn (III, IV);
• During the joint research with Canadian colleagues to determine the causes of water toxicity in the Great Lakes of the USA and Canada with wastewater from the pulp and paper industry (PPI), a method for detoxifying PPI wastewater with small additives of hydrogen peroxide was proposed for the first time;
• Based on the study of the mechanisms of photochemical transformation of nitrate and nitrite ions with toxicological control by the biotesting method, a method for denitrification accompanied by destructive purification and detoxification of multicomponent wastewater due to photoinitiation of OH radicals was proposed;
• Using a biosensor with feedback, the efficiency of the combined action of photoozonation with subsequent biological purification on adapted strains of microorganisms for the purification of local wastewater from surfactants of various natures was shown.
