Biological filtering and ecological machinery for self-purification and bioremediation in aquatic ecosystems: towards a holistic view.// Rivista di Biologia / Biology Forum. 1998. 91: 247-258. According to one of the approaches to the definition of criteria for the phenomenon of life, the key attribute is the ability of the life system for some self-regulating and self-supporting. Part of such holistic functions of aquatic ecosystems as self-regulating and self-supporting is their cleaning the water via a multitude of various mechanisms. The goal of this paper is to present some fundamental elements of the theory of ecosystem self-purification which emphasizes the importance of the four functional biological filters that are instrumental in purification and upgrading the quality of water in aquatic ecosystems. These functional filters are: (1) direct water filtering by aquatic organisms that are filter-feeders; (2) the filter (represented mainly by communities of aquatic plants/periphyton) which prevents input of pollutants and biogenic elements (N, P) from land into water bodies; (3) the filter (represented by benthic organisms) which prevents re-entry of pollutants and biogenic elements from the bottom sediments into the water; (4) the filter (represented by the microorganisms attached to the particles which are suspended in the water) that provides microbiological treatment of the water column. New experimental data by the author reveal the role of man-made effects on the ecological machinery which purifies water. The analysis and discussion lead to the holistic theory of the natural process of bioremediation of aquatic ecosystems. [An innovative analysis of the role of organisms in water filtration in ecosystems. Water filtration is a key component of ecological biomachinery for maintaining the natural purification potential of ecosystems. Among new facts: the synthetic surfactant SDS 1 mg/L inhibited filtration (35-95 min, 16°С) of bivalve Mytilus.edulis and the removal of the cells of algae Isochrysis galbana from water. Amount of cells that stayed in water unfiltered after 95 min, was 3 times as much as the amount of cells in the control without SDS].

The currently accepted system of criteria of evaluating ecological hazards from man-made chemicals (which is used in W.Europe, N.America and in some other countries) is outdated and vulnerable to criticism. The author proposed a new concept of the system of criteria for evaluating the ecological hazard from man-made impact. The author suggested to assess man-made impacts (including effects of pollutants and xenobiotics) on biota according to the following four levels of disturbance in biological and ecological systems: (1) the level of individual and populational responses; (2) the level of aggregated responses; (3) the level of stability and integrity of the ecosystem; (4) the level of contributions of the ecosystem into biospheric processes. An example is given of how to apply the proposed system of criteria to the analysis of concrete experimental data. To exemplify the efficiency of the proposed system of criteria, it is shown how to use it to analyze new data on effects of a non-ionic surfactant on water filtering by bivalves. It is concluded that the proposed system of criteria will be helpful in better assessing ecological hazards from anthropogenic effects on biota including effects of man-made chemicals polluting ecosystems.

Concept of aquatic biota as a labile and vulnerable component of the system for water self-purification. — DAN (Doklady Akademii Nauk). 2000. Vol. 372. No.2., P. 279-282 in the Russian edition.Tables, Bibliogr. 15 refs [A new vision of the role of biota in ecosystems].Translated into English:
Ostroumov S. A. The concept of aquatic biota as a labile and vulnerable component of the water self-purification system - Doklady Biological Sciences, Vol. 372, 2000, pp. 286–289. [Translated from Doklady Akademii Nauk, Vol. 372, No. 2, 2000, pp. 279–282. Original Russian text Copyright © 2000 by Ostroumov]. A new fundamental concept of the role of biota in the functioning of aquatic ecosystems is proposed. According to that concept, the complex of aquatic organisms (aquatic biota) is a central, labile and potentially vulnerable component of the water self-purification system in aquatic ecosystems. This fundamental concept leads to substantial changes in the hierarchy of priorities for protection of biodiversity and environment. According to the concept suggested in this work, the maximum allowable concentrations (MACs) for specific substances should be established after taking into account the possible effects of pollutants on the water self-purification system. Possible effects on many organisms, including filter feeders, should be taken into consideration. Both inhibiting and stimulating effects of sublethal concentrations of pollutants are dangerous, because either of them may cause an imbalance in the complicated system of water self-purification. The fundamental concept suggested in this work heightens the level of priority of the sublethal effects of pollutants. The sublethal effects leading to changes in the functional activity of populations of aquatic organisms may cause an imbalance in the system of water self-purification. Table 1.

Biocatalysis of the matter transfer in a microcosm is inhibited by a contaminant: an effect on Lymnaea stagnalis. — DAN (Doklady Akademii Nauk). 2000. Vol. 373. No.2., P. 278-280. Bibliogr. 11 refs. [In collaboration: S.A.O., Kolesnikov M.P.] Translated into English:

[In collaboration: S.A.O., Kolesnikov M.P.] www.scribd.com/doc/49069985; http://www.citeulike.org/user/ATP/article/9751191; ; PMID: 11013843 [PubMed]; By excreting some massive amount of organic matter in the form of pellets, the gastropod mollusks drive the transfer of organic matter and contribute to the biogeochemical flows of chemical elements in aquatic ecosystems. For the first time, the quantitative assessment of the biogeochemical flows was made. Also, for the first time, it was discovered that a synthetic chemical may inhibit those flows. The pellet excretion by the gastropods Lymnaea stagnalis feeding on the phytomass of macrophytes (such as Nuphar lutea) was 4–7 mg dry weight per 1 gram wet weight of the mollusks per 72 h. Pellet sedimentation contributes to the vertical transfer of chemical elements in the ecosystem. The pellet composition depended on the species of the plants eaten by the mollusks. When the gastropods L. stagnalis feed on N. lutea, the pellets contain, in addition to organic and inorganic carbon, nitrogen (N, 2.3–2.9%), phosphorus (P, 0.4–0.5%), and silicium (silicon) (Si, 1.1–1.9%). The relative content of Si was 30% higher than in the food phytomass. The synthetic surfactant tetradecyltrimethylammonium bromide (TDTMA, 2 mg/L) inhibited the feeding rate of the mollusks and pellet production, their accumulation at the bottom of microcosms, and the matter transfer connected with this. The data obtained demonstrated a new aspect of the ecological hazard due to environmental pollution with TDTMA and other quaternary ammonium compounds at sublethal concentrations. According to the author’s opinion, other contaminants may also suppress pellet production, their accumulation at the bottom, and the matter transfer associated with that. http://scipeople.ru/users/2943391/; http://sites.google.com/site/2000dbs373p397biocatallstag/;

The author developed a new fundamental concept of aquatic ecosystem as a multi-functional bioreactor. One of the key functions of that bioreactor is upgrading water quality via a multi-component biomachinery of water self-purification. New facts the were discovered: Contribution of the main groups of aquatic organisms (heterotrophic bacteria, fungi, cyanobacteria and microalgae, protozoans, higher plants, invertebrates, fish and amphibians) to water self-purification: comparison and analysis (Tabl.1). 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), a significant inhibition by Triton X-100 of the filtration by Mytilus edulis (4 mg/L), and by Unio tumidus (5 mg/L). The Iinhibitory effects of TDTMA 1 mg/L on M. galloprovincialis (Tabl.2); the 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 (Tabl. 3). Fragments of the text: "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 monetary cost estimates of ecosystems and biota should be increased" (p. 516). http://www.ncbi.nlm.nih.gov/pubmed/11103331;
