Аннотация Ostroumov S. A. The theory of the hydrobiological mechanism of water self-purification in water bodies: from theory to practice [Proceedings of the 4th International Iran and Russia Conference in Agricluture and Natural Resources. Shahrekord-Iran. Sept. 8-10, 2004]. p.(p.1251 -1253. Bibliogr. 11 refs). Sergei A. Ostroumov Faculty of Biology, Lomonosov Moscow State University, Moscow 119234; Russia; Email: saostro@online.ru Abstract.New data on effects of chemicals (surfactants) on water filtration by aquatic invertebrates are reported. The basics of the new theory of the polyfunctional role of biota in self-purification of water in aquatic ecosystems (lakes, rivers, man-made reservoirs) are formulated. The theory covers the following: sources of energy for the mechanisms of self-purification; the main functional blocks of the mechanism of water self-purification; the system of the main processes that are involved; analysis of the degree of participation of the main groups of aquatic organisms; degree of reliability and the main mechanisms providing the reliability of water self-purification; biotic regulation of the processes; the attitude of the mechanism of self-purification towards the external influences/impacts; applications and conclusions relevant to the practice of sustainable use of water resources, including some new approaches in preventing eutrophication and chemical pollution. --Key Words: pollution, water quality, theory of water self-purification, lakes, rivers, role of organisms, biota, functioning, aquatic ecosystems, ecotoxicology, sustainable use of aquatic resources, environmental safety, toxicants, pollutants, xenobiotics, freshwater and marine ecosystems, sodium dodecyl sulphate,SDS; tetradecyltrimethylammonium bromide,TDTMA; Triton X-100, synthetic surfactants, tensides, new bioassays, anthropogenic effects,man-made effects,wastewater treatment http://iirc.narod.ru/4conference/Fullpaper/40037.pdf
