According to one of the approaches to the definition of criteria for the phenomenon of life, the key attribute is the ability of the 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 microorganisms attached to particles which are suspended in the water) that provides microbiological treatment of 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. http://www.ncbi.nlm.nih.gov/pubmed/9857844?dopt=Abstract; PMID: 9857844 [PubMed - indexed for MEDLINE];

Ostroumov S.A. Biotic self-purification of aquatic ecosystems: From the theory to ecotechnologies. – Ecologica 2007, vol. 15, No. 50, p. 15-21. (Faculty of Biology, Moscow State University, Moscow, Russia) Basic elements of a new theory for the biological mechanism for water self-purification are presented. Hydrobionts (aquatic organisms) are actively involved in various processes leading to water purification. Not only microorganisms (bacteria, cyanobacteria and fungi), but also algae, plants, invertebrates, and many other groups of organisms are involved, which is discussed and analyzed in the paper. Results of the author's experiments that study the effects of various pollutants on aquatic organisms (freshwater and marine bivalves) are given. The theory is an innovative basis for developing ecological technologies to clean water and to upgrade its quality by using organisms and ecosystems. This paper generalizes and systematizes the basics of the author’s theory of the multifunctional role that the biota plays in the self-purification and ecological remediation of aquatic ecosystems using the results of previous analyses and the theory of the functioning of aquatic ecosystems. It is expected that on the basis of this theory some efficient ecotechnologies will emerge to remediate and restore polluted aquatic systems. The paper is based on the presentations that the author made at a scientific seminar in the V.I. Vernadsky Institute of Geochemistry and Analytical Chemistry, at the conferences 'Aquatic Ecosystems and Organisms-6' (the 6th international conference that was run in Moscow in 2004) and 'Aquatic Ecosystems and Organisms-7' (the 7th international conference, Moscow, 2005), XXIX Congress of International Association of Theoretical and Applied Limnology, and other conferences.
