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.

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

Effects of SDS, TDTMA, and Triton X-100 on M. edulis and M. edulis / M. galloprovincialis. Effects of three surfactants on the filtration rates by marine mussels were studied. The xenobiotics tested represented anionic, cationic and non-ionic surfactants (tetradecyltrimethylammonium bromide, a representative of a class of cationic surfactants; sodium dodecyl sulphate, a representative of anionic alkyl sulfates; and Triton X-100, a representative of non-ionic hydroxyethylated alkyl phenols). All three surfactants inhibited the clearance rates. The significance of the results for the ecology of marine ecosystems is discussed].
