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

Ostroumov S.А., Widdows J. Inhibition of mussel suspension feeding by surfactants of three classes // Hydrobiologia. 2006. Vol. 556, No. 1. Pages: 381 – 386. 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].

Relatively small effects of Triton X-100 4-5 mg/L on Hyphomonas sp. MHS-3 (5 mg/L) and Hyphomonas sp. VP-6 (5-10 mg/L), significant inhibition by Triton X-100 of filtration by Mytilus edulis (4 mg/L), and by Unio tumidus (5 mg/L). Inhibitory effects of TDTMA 1 mg/L on M. galloprovincialis (Table 2); inhibition of feeding: effects of TX100 1-5 mg/L on Unio tumidus, TDTMA 1-2 mg/L on U. pictorum; TDTMA 1 mg/L, SDS 1.7 mg/L, detergents 6.7 – 50 mg/L, AHC 5-60 mg/L (sublethal concentrations) on M. galloprovincialis; TX100, TDTMA (2 mg/L), Tide-Lemon 75 mg/L on Lymnaea stagnalis (Table 3). "Sublethal concentrations of contaminants may inhibit vital activities of other organisms involved in the function of an ecosystem as an analogue of a bioreactor. This finding provides a deeper insight into the mechanisms of anthropogenic impact on biosphere. The concept put forward in this work emphasizes that intactness of the whole range of biological diversity of hydrobionts is required to provide effective functioning of an ecosystem as an analog of a water self-purification bioreactor. Therefore, the cost estimates of ecosystems and biota should be increased" (p.516)].
