AB Copper is one of the key heavy metals that pollute environment and
constitute a serious threat to the health of humans and ecosystems.
Copper may enter the aquatic environment in both soluble and
nanoparticle form. It was previously found in a series of studies that
nanoparticles, including those of several metal oxides, exercise both
negative and positive effects on the higher plants which makes necessary
further research on the interaction between metal oxide nanoparticles
and plants. Interactions between aquatic plants and copper-containing
nanoparticles were not sufficiently studied. The goal of this study was
to contribute to the investigation of the interactions between CuO
nanoparticles and the aquatic plant Elodea canadensis under the
conditions of experimental microcosms. It was found that CuO
nanoparticles demonstrated some phytotoxicity to Elodea canadensis.
After the incubation of Elodea canadensis in the aquatic medium
contaminated with CuO nanoparticles there was a significant increase (by
two orders of magnitude) of the concentration of copper in the biomass
of the plants.

AB The 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.

Viviparus viviparus, Unio pictorum, and plants 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

AB Earlier, the author published two books and some papers, in which he
described conceptual foundations of new scientific disciplines -
biochemical ecology and biochemical hydrobiology. These trends in
research include studies of the role of chemical substances in
interorganismal interactions, in communication and regulation of
supraorganismal systems. Another part of biochemical ecology concerns
studies of the destiny and transformation of external chemical
substances when they interact with the organisms. Both natural and
man-made compounds are interesting for biochemical ecology. The basic
concepts of biochemical ecology include ecological chemomediators and
ecological chemoregulators that have already been included in the body
of modem conceptions and are used in modem ecological literature.
Application of biochemical ecology to aquatic ecosystems creates the
basis for development of biochemical hydrobiology.

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.

AB 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.

AB 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. 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).

AB Effects 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.

AB The 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. (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
experimental studies, an example is given of bow 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.

AB Top-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.

AB The 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.

AB 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: (I) 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.

In the presence of 0.1 mg/l TX the cell density in the culture was
markedly lower than in the control culture. In the presence of 1 mg/l TX
the decrease in cell density exceeded 50%. The decrease n the specific
growth rate was about 10% in the presence of 0.1 mg/l TX and about 40%
in the presence of 1 mg/l TX (over the period of seven days). The diatom
sensitivity to TX was higher than that of some red and green algae and
chrysophytes, as well as that of starfish spermatozoa acid plant
seedlings to TX or similar surfactants. These data reveal some more
aspects of the ecological danger of aquatic pollution by non-ionogenic

variety) to pollution of the aqueous medium with polymeric surfactants -
a copolymer of hexene and maleic aldehyde (CHMA), which is used in some
industries and may be contained in wastewaters. It was shown that CHMA
in certain concentrations causes noticeable inhibition of the plantlets.
Such action was established, in particular, with CHMA content in the
water corresponding to a concentration of the active substance Of
0.4-0.9 mg/ml. The effect was revealed with prolonged incubation of
germinating seeds for 43-67 h or more. It is suggested that the data
obtained be taken into account in analyzing the still insufficiently
studied question of possible ecological consequences of irrigating lands
with wastewaters and polluted waters.

AB Copper is one of the key heavy metals that pollute environment and
constitute a serious threat to the health of humans and ecosystems.
Copper may enter the aquatic environment in both soluble and
nanoparticle form. It was previously found in a series of studies that
nanoparticles, including those of several metal oxides, exercise both
negative and positive effects on the higher plants which makes necessary
further research on the interaction between metal oxide nanoparticles
and plants. Interactions between aquatic plants and copper-containing
nanoparticles were not sufficiently studied. The goal of this study was
to contribute to the investigation of the interactions between CuO
nanoparticles and the aquatic plant Elodea canadensis under the
conditions of experimental microcosms. It was found that CuO
nanoparticles demonstrated some phytotoxicity to Elodea canadensis.
After the incubation of Elodea canadensis in the aquatic medium
contaminated with CuO nanoparticles there was a significant increase (by
two orders of magnitude) of the concentration of copper in the biomass
of the plants.

AB The 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.

Viviparus viviparus, Unio pictorum, and plants 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.

AB Earlier, the author published two books and some papers, in which he
described conceptual foundations of new scientific disciplines -
biochemical ecology and biochemical hydrobiology. These trends in
research include studies of the role of chemical substances in
interorganismal interactions, in communication and regulation of
supraorganismal systems. Another part of biochemical ecology concerns
studies of the destiny and transformation of external chemical
substances when they interact with the organisms. Both natural and
man-made compounds are interesting for biochemical ecology. The basic
concepts of biochemical ecology include ecological chemomediators and
ecological chemoregulators that have already been included in the body
of modem conceptions and are used in modem ecological literature.
Application of biochemical ecology to aquatic ecosystems creates the
basis for development of biochemical hydrobiology.

results of the author's experiments with filtering hydrobionts have been

AB 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.

AB 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. 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).

AB Effects 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.

AB The 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. (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
experimental studies, an example is given of bow 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.

AB Top-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.

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.

AB 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: (I) 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.

AB The effects of the non-ionogenic surfactant, Triton X-100 (TX), on the
growth of cultured centric diatom Thalassiosira pseudonana were studied.
In the presence of 0.1 mg/l TX the cell density in the culture was
markedly lower than in the control culture. In the presence of 1 mg/l TX
the decrease in cell density exceeded 50%. The decrease n the specific
growth rate was about 10% in the presence of 0.1 mg/l TX and about 40%
in the presence of 1 mg/l TX (over the period of seven days). The diatom
sensitivity to TX was higher than that of some red and green algae and
chrysophytes, as well as that of starfish spermatozoa acid plant
seedlings to TX or similar surfactants. These data reveal some more
aspects of the ecological danger of aquatic pollution by non-ionogenic
surfactants.

AB The authors investigated the reaction of buckwheat plantlets (Shatilov-5
variety) to pollution of the aqueous medium with polymeric surfactants -
a copolymer of hexene and maleic aldehyde (CHMA), which is used in some
industries and may be contained in wastewaters. It was shown that CHMA
in certain concentrations causes noticeable inhibition of the plantlets.
Such action was established, in particular, with CHMA content in the
water corresponding to a concentration of the active substance Of
0.4-0.9 mg/ml. The effect was revealed with prolonged incubation of
germinating seeds for 43-67 h or more. It is suggested that the data
obtained be taken into account in analyzing the still insufficiently
studied question of possible ecological consequences of irrigating lands
with wastewaters and polluted waters.
