A.P. Sadchikov, S.A. Ostroumov, Issues of the Study of Detritus in Aquatic Systems. - Russian Journal of General Chemistry, 2017, Vol. 87, No. 13, pp. 3244–3249. © Pleiades Publishing, Ltd., 2017.
Original Russian Text © A.P. Sadchikov, S.A. Ostroumov, 2017, published in Ekologicheskaya Khimiya, 2017, Vol. 26, No. 5, pp. 262–270. Issues of the Study of Detritus in Aquatic Systems; A. P. Sadchikov and S. A. Ostroumov*; Faculty of Biology, Moscow State University, Moscow, 119991 Russia ;
In this paper, the authors presented an innovative analysis of the ecological roles of detritus and suspended particulate matter in aquatic ecosystems. New data that have been obtained for freshwater ecosyst ems of the central part of Russian Federation (Moscow Region, e.g., Mozhaiskoe Rese rvoir) have been included in the analysis. These new data include the results of studies of samples of water and detritus from the aquatic ecosystems. The review analysis addresses both freshwater and marine ecosystems. The multifunctional important role of detritus in aquatic ecosystems has been shown and exemplified using data for aquatic bodies of different trophic level, from oligotrophic to eutrophic.
Keywords: detritus, aquatic ecosystems, particulate organic matter, particulate organic carbon, freshwater ecosystems, marine ecosystems, ocean, oligotrophic, mesotrophic, eutrophic;

This article presents the recent author's discovery of new aspects of the participation of organisms in the detoxification system of the biosphere. Problems of detoxification of toxic environmental pollutants are analyzed. New author’s experimental data in combination with a large amount of information in the scientific literature gave rise to a new concept of the role of biogenic detritus and related nutrients in environmental detoxification (ex-living matter concept). This may be useful for the development of new technologies for remediation and decontamination of the environment.
Keywords: biosphere, detoxification, pollution control, toxic chemical elements, immobilization, sorption, biogenic detritus, ex-living matter;

Water Quality and Conditioning in Natural Ecosystems: Biomachinery Theory of Self-Purification of Water
Ostroumov S.A., Water Quality and Conditioning in Natural Ecosystems: Biomachinery Theory of Self-Purification of Water. - Russian Journal of General Chemistry, 2017, Vol. 87, No. 13, pp. 3199–3204. ISSN 1070-3632,
The paper presents updated author's theory of aquatic biomachinery (a new term of the author), in other words, ecological qualitative theory of formation of water quality in aquatic ecosystems. This theory provides fundamentals of water purification in aquatic ecosystes (water self-purification). The article formulated an updated list of fundamental principles of the author's theory of polyfunctional (multifunctional) role of biota (sum of organisms) in self-purification of water in aquatic ecosystems. The theory includes the following elements: (1) energy sources for self-purification of aquatic ecosystems; (2) main functional units of the self-purification system; (3) main self-purification processes; (4) contributions of major taxa to self-purification of aquatic ecosystems; (5) reliability of the system and mechanisms ensuring it; (6) self-regulation of biota; (7) response of the system to external stimuli (impacts); (8) analogy between an ecosystem and a bioreactor; (9) conclusions for nature conservation practice. The theory covers both freshwater and marine ecosystems.
