Abstract
Basic elements are formulated for a qualitative theory of the polyfunctional role of the biota in maintaining self-purification and water quality in aquatic ecosystems. The elements of the theory covers the following: (1) sources of energy for the mechanisms of selfpurification; (2) the main functional blocks of the system of self-purification; (3) the list of the main processes that are involved; (4) analysis of the degree of participation of the main large taxons; (5) degree of reliability and the main mechanisms providing the reliability; (6) regulation of the processes; (7) the response of the system towards the external influences (man-made impacts); (8) the analogy between ecosystems and a bioreactor; and (9) conclusions relevant to the practice of biodiversity conservation. In support of the theory, results are given of the author's experiments which demonstrated the ability of some pollutants (surfactants, detergents, and some others) to inhibit the water filtration activity of marine filter-feeders (namely, the bivalve mollusks Mytilus galloprovincialis, Mytilus edulis, and Crassostrea gigas).

Abstract
—Principles of the theory of the ecological mechanism of water self-purification based on multiple functions of the biota in freshwater and marine ecosystems are formulated. In developing this theory, the results of the author’s experiments with filtering hydrobionts have been used. These results indicate that the water self-purification mechanism is vulnerable to the impact of some pollutants and, in particular, surfactants. Conclusions drawn on the basis of the theory have practical significance for biodiversity conservation and for the sustainable
use of the biological resources of aquatic ecosystems.

It was discovered that the aquatic plant (macrophyte) Ceratophyllum demersum immobilized gold (Au) nanoparticles after their addition to water. It is the first time it was shown. The method that was used to detect and measure the conctntrations of gold in the biomass of plants (phytomass) was NAA (neutron activation analysis).

Responses of Unio tumidus to mixed chemical preparations and the hazard of synecological summation of anthropogenic effects. - Doklady Biological Sciences, 2001, Volume 380, Numbers 1-6, p. 492-495. ISSN 0012-4966 (Print) 1608-3105 (Online). DOI 10.1023/A:1012344026176. The author introduced a new concept and term, “the synecological summation of the effects of anthropogenic factors on organisms”. In the new author’s experiments, the effects of commercial detergents, which are chemical mixtures, on bivalves (detergent OMO, freshwater mussels Unio tumidus) were studied. Detergents exert two types of hazardous effects on organisms and ecosystems: the phosphorus-induced stimulation of phytoplankton growth and surfactant-induced inhibition of filter-feeders. Because filter-feeders are an effective natural factor of control of unicellular plankton populations, the two types of the detergent-induced effects on ecosystem facilitate the growth of phytoplankton populations. Therefore, these effects sum together, thereby increasing the hazard of the man-made impact on the ecosystem. The results contribute to a better understanding of the potential ecological danger of pollutants for integral functions of ecosystems. It is the synecological summation of the effects of anthropogenic factors on plankton populations and filter-feeders that is of particular concern. The interaction between populations of plankton organisms and filter-feeders that feed on plankton should be taken into consideration in the studies on the ecological effects of synthetic detergents on these populations. Situations of man-made impact should be analyzed with using the synecological approach to the problem. http://sites.google.com/site/2001dbs380p492unio/; www.springerlink.com/index/L33309208H28L87R.pdf; DOI 10.1023/A:1012344026176;

Contemporary Problems of Ecology, 2008, Vol. 1, No. 1, p. 147-152. http://scipeople.com/publication/99105/; Water self-purification is an important example of ecosystem services. This function of aquatic ecosystems is necessary for sustainable development, and for sustainable use of aquatic resources (water resources), as well for environmental safety.
The analysis made by the author in a published paper (Ostroumov, 2008) showed that aquatic ecosystem (both marine and freshwater one) features a multi-component
molecular-ecological mechanism for upgrading water quality. In other words, it is a multi-component, multi-process biomachinery for water quality formation and self-purification. The biomachinery includes the following items: (1) sources of energy for self-purification mechanisms, (2) the major taxa of living organisms as components of the biomachinery; (3) the biomachinery contains the functional blocks that perform functions of filters, mills, and pumps.
The experiments that the author carried out demonstrated how several types of chemical pollutants may produce damage to this delicate and very useful biomachinery which makes water clean. The experiments demonstrated that some chemical pollutants decreased important and useful functions of aquatic invertebrate animals which contribute to purification of water. We have found that the chemical pollutant as diverse as synthetic surfactants, detergents, salts of Cd, Cu, Pb, Hg, Co, Ti, V (Na3VO4 •12 H2O), and oil hydrocarbons inhibited water filtration by bivalve molluscs, the marine mussels (the Latin name of the mussels: Mytilus galloprovincialis).
One of the practical conclusions is that we now see another additional aspect of important hazard from the low, sublethal concentrations of the chemicals that pollute the aquatic environment. Not only death of aquatic organisms, but also even a decrease of their functional activity in polluted aquatic ecosystems poses some danger and risk to the water system. The potential hazard of those low levels of the chemical pollutants is that the potential of the ecosystem to purify water will be decreased. As a final result, in future we may have water of worse quality.
This may be of interest to the scientists and specialists in the following fields: aquatic ecology, water science, environmental toxicology and chemistry, ecotoxicology, and water resource management.

The course is intended to show the problems of the modern environment and importance of the fundamental concept of sustainable development. It is important to make a point in stressing the role of science in finding the solutions. The course is intended for the university students mainly of the 2nd and 3rd years of education but can be adapted for students of other years as well. The course can be included in the program of education of the students majoring in both science and humanities. The lecture course can be supplemented by the assignment of writing a course work on any relevant topic mentioned in the course. The course work can be focused on a scientific aspect of environmental change or on environmental law or on implementing environmental law and agreements. The course is structured into 9 blocks that are labeled below as 'parts'. Because the parts are of unequal size, they do not coincide with the division into lectures.
