- 2014;© 2014, Allerton Press, Inc. Increased production and use of nanomaterials can lead to new types of pollution of the environment, including aquatic ecosystems. Pollution of the aqueous environment with nanoparticles can be a new type of pollution of the environment. This requires a more detailed study of the biological effects during exposure of nanoparticles on aquatic organisms. The interactions of gold nanoparticles (Au) with water plants, aquatic macrophytes (Ceratophyllum demersum) have been studied. Aquatic microcosms with these plants were used. Gold nanoparticles (Au) were added to the aqueous medium of the C. demersum macrophyte containing microcosms. The state of the plants was then analyzed. Phytotoxicity of Au nanoparticles for aquatic macrophytes was shown for the first time. A new method of phytotoxicity detection was suggested and successfully approved. Phytotoxicity at a concentration of Au (in the form of nanoparticles) of 6 × 10−6 M-1.8 × 10−5 M was shown.

The presence of viable hydrocarbon-oxidizing microorganisms has been shown in the under-ground waters exposed by the Vorotilovskaya deep well (the Puchezh-Katunki astrobleme, 75 km north of Nizhny Novgorod, 1900- and 3200-m deep) using the method of chromatography-mass spectrometry of specific biomarkers of the microbial cell wall and the classical methods of bacteriology. Several microbial species have been isolated in pure culture and identified. Two bacillary species, Bacillus pumilus KTB-2 and Bacillus subtilis KTB-4, were maintained in pure cultures at reinoculations. The effects of mineralization and aeration of the medium on the growth characteristics of Bacillus pumilus KTB-2 in batch culture have been studied. © 2013 Allerton Press, Inc. - 2010The experimental data analysis, concepts, and generalizations in this article provide the fundamental elements of the qualitative theory of biocontrol of water quality in a systematized form. The theory covers water self-purification in freshwater and marine ecosystems. The theory is supported by the results of the author's experimental studies of the effects exerted by some chemical pollutants including synthetic surfactants, detergents, and other xenobiotics onaquatic organisms. The theory provides a basis for remediation of polluted aquatic ecosystems including purification of water bodies and streams, and briefly present the qualitative theory of the self-purification mechanism of aquatic ecosystems, phytoremediation and other types of technologies. © 2010 Pleiades Publishing, Ltd.
- 20100Biodetritus that formed over a 7-month period in microcosms with Viviparus viviparus, Unio pictorum, and Ceratophyllum demersum contained a number of elements. This is the first study to determine concentrations of some elements in biodetritus. Neutron activation analysis showed that the elements' concentrations decrease in the following order: Ca > Zn > Ba > Br > Ce > Se > Nd > La > U > Hf > Sb > Th > Sm > S > Cs > Au. The data obtained contribute to understanding of the polyfunctional role of aquatic organisms in aquatic ecosystems. © 2010 Pleiades Publishing, Ltd.

- 20080The paper formulates some basics of the modern ecological theory of the polyfunctional role of biota in the molecular-ecological mechanism of water quality formation and self-purification of aquatic ecosystems. The theory covers the following items: (1) sources of energy for self-purification mechanisms, (2) the main structural and functional units of the self-purification system, (3) the main processes involved in the system, (4) contributions of major taxa to self-purification, (5) system reliability and supporting mechanisms, (6) the response of the system as a whole to external factors, (7) particulars of the operation of water purification mechanisms, and (8) conclusions and recommendations for biodiversity preservation practice. © 2008 Pleiades Publishing, Inc.
- 2006Effects 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. © Springer 2006.
- 2005Principles 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. © 2005 Pleiades Publishing, Inc.
- On the basis of the previous publications, our new data and the existing scientific literature, we have formulated some fundamental principles that characterize the pivotal roles of the biodiversity of filter-feeders in ecosystems. Among those roles are: (1) the role of ecological repair of water quality, (2) the role of contributing to reliability and stability of the functioning of the ecosystem, (3) the role of contributing to creation of habitat heterogeneity, (4) the role of contributing to acceleration of migration of chemical elements. It is an important feature of the biomachinery of filter-feeders that it removes from water various particles of a very broad range of sizes. Another important principle is that the amount of the organic matter filtered out of water is larger than the amount assimilated so that a significant part of the removed material serves no useful function to the organism of the filter-feeder, but serves a beneficial function to some other species and to the ecosystem as a whole. The new experiments by the author additionally demonstrated a vulnerability of the filtration activity of filter feeders (e.g., bivalves and rotifers) to some xenobiotics (tetradecyltrymethylammonium bromide, heavy metals and some others). The inhibition of the filtration activity of filter-feeders may lead to the situation previously described as that of an ecological bomb of the second type. © Springer 2005.

- 2004In the integrated and systematized form presented are some elements of the theory of polyfunctional role of biota in self-purification of aquatic ecosystems and their ecological remediation. The analysis is based on the data of previous works and theory of aquatic system functioning.
- 20040Long-term studies of the biological effect of surfactants, including the effect surfactants exert on filter feeders, are reviewed. The role of filter feeders in the functioning of freshwater and marine ecosystems is analyzed. New aspects in the assessment of environmental hazard due to the impact of chemical pollutants, including surfactants and detergents, are established. © 2004 MAIK "Nauka/Interperiodica".
- 20040A fundamental concept is proposed of aquatic ecosystem as a bioreactor that carries out the function of water purification in natural water bodies and streams. The 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 experimental data on xenobiotics-induced inhibition of the functioning of the molluscs Unio tumidus, U. pictorum, M. galloprovincialis and Limnaea stagnalis emphasize the potential ecological hazard from sublethal concentrations of pollutants (including those exemplified by synthetic surfactants and detergents).

- 20030The influence of some surface active substances on the filtration activity of marine Bivalvia was studied. It has been found that both anionic (sodium dodecylsulphate) and cationic (tetradecyltrimethylammonium bromide) surfactants inhibited the filtration activity of oysters (Crassostrea gigas). Some mixtures containing surface active substances also inhibited the filtration activity of C. gigas and Mytilus galloprovincialis. The obtained data correlate well with the results obtained previously. They suggest that some xenobiotics and pollutants inhibited the filtration activity of other species of marine and freshwater Bivalvia. This experimental approach is useful in evaluating the influence of surface active substances on marine ecosystems.
- 2003Research priorities in ecology and environmental sciences for the future are formulated. The priorities for both fundamental and applied ecology are proposed. The list of priorities includes 50 items. The priorities are relevant to terrestrial, aquatic, and general ecology. The list of priorities is helpful when grant proposals are being prepared, evaluated, and selected for funding.

- 2003The currently accepted system of criteria for evaluating environmental and ecological hazards of man-made chemicals (pollutants) is vulnerable to criticism. 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: (I) 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. 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. 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.
- 2003Effects of several surfactants and chemical mixtures on marine bivalves were studied. An anionic surfactant, sodium dodecylsulphate (SDS), and a cationic surfactant, tetradecyltrimethylammonium bromide (TDTMA), inhibited the filtering activity of oysters (Crassostrea gigas). Similar effects were exhibited by some chemical mixtures that included surfactants. Those mixtures inhibited the filtering activity of Crassostrea gigas and Mytilus galloprovincialis. The new results are in agreement with the author's previous experiments, where a number of xenobiotics and/or pollutants inhibited the filtering activity of several species of marine and freshwater bivalves, e.g., it had been shown that SDS inhibited filtering activity of Mytilus edulis (e.g., Ostroumov, 2000c, 2001a). This experimental approach is helpful in assessment of environmental hazards from man-made chemicals that can contaminate marine systems.

- 2002Top-down control is an important type of interspecies interactions in food webs. It is especially important for aquatic ecosystems. Phytoplankton grazers contribute to the top-down control of phytoplankton populations. The paper is focused on the role of benthic filter feeders in the control of plankton populations as a result of water filtering and the removal of cells of plankton from the water column. New data on the inhibitory effects of surfactants and detergents on benthic filter-feeders (Unio tumidus, U. pictorum, Mytilus galloprovincialis, M. edulis and Crassostrea gigas) are presented and discussed. Importance and efficiency of that approach to the problems of eutrophication and water self-purification is pointed out. Chemical pollution may pose a threat to the natural top-down control of phytoplankton and water self-purification process. The latter is considered an important prerequisite for sustainable use of aquatic resources.

- 20010The effect of synthetic anionic surface active substance (SAS) sodium dodecylsulfate (SDS, 4 mg/l) on the kinetics of water filtration by mussel Mytilus edulis was studied. A suspension of algae Isochrysis galbana was added to the vessel with the mussels, and their filtration activity was measured by counting the concentration of the algae cells in the experimental vessels. Algae concentration was measured every 30 min for an hour and a half. The inhibiting effect on the mollusk filtration rate (FR) was qualitatively described. After the first 30 min filtration at 4 mg/l initial SDS concentration, the cell density was 322% of the control. The inhibiting effect was observed later as well. Due to FR inhibition in the vessels with the above specified initial SDS concentration, the algae cell density was 6.4 and 14.7 times that of the control after 1 and 1.5 h, respectively. Thus, SAS SDS can decrease the natural capacity of aquatic ecosystems for self-purification and disturb other aspects of ecosystem functioning through inhibiting the filtration activity of mussels. The obtained data are discussed in the context of environment and hydrosphere protection from pollution.
