It is the first paper in which a synthesis of both authors new experimental data and international literature was made, which led to a new broad picture of the role of biological filtering in self-purification and self-bioremediation of aquatic ecosystems.

ABSTRACT:
NEW IDEAS, NEW CONCEPTUALIZATION: 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 FACTS: 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.

A new set of criteria in order to answer the question was formulated in this paper: is a given chemical substance hazardous to environment or not?
**
ABSTRACT:
The currently accepted system of criteria for evaluating environmental and ecological hazards of man-made chemicals (pollutants) is vulnerable to criticism. NEW IDEAS: In this paper, a new concept of the system of approaches towards criteria for evaluating the ecological hazard from man-made impact is proposed. It is suggested to assess the man-made impacts (including effects of pollutants and xenobiotics) on the biota according to the following four levels of disturbance in biological and ecological systems: (1) the level of individual responses; (2) the level of aggregated responses of groups of organisms; (3) the level of stability and integrity of the ecosystem; (4) the level of contributions of the ecosystem to biospheric processes. On the basis of the author's experimental studies, an example is given of how to apply the proposed approach and the system of criteria to the analysis of concrete experimental data. NEW FACTS: To exemplify the efficiency of the proposed approach, it is shown how to use it to analyze new data on effects of a synthetic surfactant on water filtering by bivalves. CONCLUSION: It is concluded that the proposed approach will be helpful in better assessing environmental and ecological hazards from anthropogenic effects on biota, including effects of man-made chemicals polluting ecosystems.

Aquatic ecosystem as a bioreactor: water purification and some other functions.
Rivista di Biologia, Vol. 97, No. 1. (2004), pp. 67-78

Abstract:
NEW IDEAS are presented: A fundamental concept is proposed of aquatic ecosystem as a bioreactor that carries out the function of water purification in natural water bodies and streams. According to the new conceptualization that was suggested by the auhtor, an ecosystem as a bioreactor has the following characteristic attributes: (1) it is a large-scale (large-volume) bioreactor; (2) it is a diversified (in terms of the number of taxa and the scope of functional activities) bioreactor; (3) it possesses a broad range of biocatalytic (chemical-transforming and degrading) capabilities.
NEW FACTS were obtained in the experiments of the author: New experimental data on xenobiotics-induced inhibition of the functional activity of the molluscs Unio tumidus, U. pictorum, M. galloprovincialis and Limnaea (Lymnaea) stagnalis demonstrated a new type of the environmental hazard from sublethal concentrations of pollutants (exemplified by synthetic surfactants and detergents).
