The concept of aquatic biota as a labile and vulnerable component of the water self-purification system.

Novelty:
The paper presents some new ideas and new facts.
** NEW IDEAS: A new fundamental conceptualization of the role of biota in the functioning of aquatic
ecosystems is proposed. According to the new conceptualization that was suggested by the author,
the complex of aquatic organisms (aquatic biota) is a central, labile and potentially vulnerable
component of the water self-purification system in aquatic ecosystems. This fundamental concept
leads to substantial changes in the hierarchy of priorities for protection of biodiversity and
environment. According to the concept suggested in this work, the maximum allowable concentrations
(MACs) for specific substances should be established after taking into account the possible effects of
pollutants on the water self-purification system. Possible effects on many organisms, including filter
feeders, should be taken into consideration. Both inhibiting and stimulating effects of sublethal
concentrations of pollutants are dangerous, because either of them may cause an imbalance in the
complicated system of water self-purification. The fundamental concept suggested in this work
heightens the level of priority of the sublethal effects of pollutants. The sublethal effects leading to
changes in the functional activity of populations of aquatic organisms may cause an imbalance in the
system of water self-purification.
NEW FACTS: new data on toxic effects of organic chemicals (detergents) on functional activity of
bivalve mollusks, namely on their filtration activity.

NOVELTY:
It is the first paper that reported two new experimental results with the
great pond snail [Lymnaea stagnalis].
First, the new author’s experiments measured the mollusk-driven fluxes of the matter and
chemical elements in a model ecosystem.
Second, the authors got another innovative result: a discovery of new toxic effects of
chemical pollutants.
Namely, these biologically driven flows of the chemical elements were decreased by a
chemical pollutant exemplified by a synthetic surfactant ( Surface-Active Agent , Quaternary
Ammonium Compound).
The fluxes of these chemical elements were studied:
carbon (C), nitrogen (N), phosphorus (P), and silicon (Si).

EXPLANATION of and comment on TERMINOLOGY:
cationic amphiphilic compound = cationic surfactant, namely, Surface-Active Agent, in this paper it is the
cationic surfactant tetradecyltrimethylammonium bromide (TDTMA); a new toxic effect of this chemical
was discovered. This chemical exemplifies a new type of hazardous contaminants (pollutants) of water.
Rotifers: Rotifers are an important part of the freshwater zooplankton, being a major foodsource
and with many species also contributing to the decomposition of soil organic matter. Most rotifers
are around 0.1–0.5 mm long , and are common in freshwater environments throughout the
world. The word "rotifer" is derived from a Latin word meaning "wheel-bearer", due to the corona
around the mouth that in concerted sequential motion resembles a wheel (though the organ does
not actually rotate). The coronal cilia create a current that sweeps food into the mouth. Rotifers eat
particulate organic detritus, dead bacteria, algae, and protozoans. They eat particles up to 10
micrometres in size. Like crustaceans, rotifers contribute to nutrient recycling. For this reason, they
are used in fish tanks to help clean the water, to prevent clouds of waste matter.

EXPLANATION of the terminology: pellets are the particles of undigested matter (mainly
biomass of undigested food) that the mollusks (the great pond snails and freshwater mussels)
excrete so that these mollusks function as engines that drive the transfer of a significant
amount of organic matter.
NOVELTY:
First measurements of concentrations of some chemical elements (C, N, P, Si, and Al) in the pellets of
aquatic mollusks. The first measurements of the biogeochemical fluxes of those elements with the
pellets. A discovery of a new type of geochemical fluxes of chemical elements in the biosphere: the
vertical (downward) flux of the elements toward the bottom of freshwater ecosystems, via pellets of
bivalves (freshwater mussels, Unio sp. and other species).

Abstract
Generation of membrane potential (delta psi) and transmembrane pH difference (delta pH) was studied in PPienergized chromatophores of Rhodospirillum rubrum by means of measurements of carotenoid and
bacteriochlorophyll absorption changes, atebrin and 8-anilinonaphthalene-1-sulphonate fluorescence
responses, and phenyldicarbaundecaborane transport. The data obtained are consistent with the suggestion
that carotenoid, bacteriochlorophyll and phenyldicarbaundecaborane responses are indicators of delta psi,
while an atebrin response is an indicator of delta pH. The fluorescence of 8-anilinonaphthalene-1-sulphonate is
affected both by delta psi and delta pH.

The concept of aquatic biota as a labile and vulnerable component of the water self-purification system.

Novelty:
The paper presents some new ideas and new facts.
** NEW IDEAS: A new fundamental conceptualization of the role of biota in the functioning of aquatic
ecosystems is proposed. According to the new conceptualization that was suggested by the author,
the complex of aquatic organisms (aquatic biota) is a central, labile and potentially vulnerable
component of the water self-purification system in aquatic ecosystems. This fundamental concept
leads to substantial changes in the hierarchy of priorities for protection of biodiversity and
environment. According to the concept suggested in this work, the maximum allowable concentrations
(MACs) for specific substances should be established after taking into account the possible effects of
pollutants on the water self-purification system. Possible effects on many organisms, including filter
feeders, should be taken into consideration. Both inhibiting and stimulating effects of sublethal
concentrations of pollutants are dangerous, because either of them may cause an imbalance in the
complicated system of water self-purification. The fundamental concept suggested in this work
heightens the level of priority of the sublethal effects of pollutants. The sublethal effects leading to
changes in the functional activity of populations of aquatic organisms may cause an imbalance in the
system of water self-purification.
NEW FACTS: new data on toxic effects of organic chemicals (detergents) on functional activity of
bivalve mollusks, namely on their filtration activity.

NOVELTY:
It is the first paper that reported two new experimental results with the
great pond snail [Lymnaea stagnalis].
First, the new author’s experiments measured the mollusk-driven fluxes of the matter and
chemical elements in a model ecosystem.
Second, the authors got another innovative result: a discovery of new toxic effects of
chemical pollutants.
Namely, these biologically driven flows of the chemical elements were decreased by a
chemical pollutant exemplified by a synthetic surfactant ( Surface-Active Agent , Quaternary
Ammonium Compound).
The fluxes of these chemical elements were studied:
carbon (C), nitrogen (N), phosphorus (P), and silicon (Si).

EXPLANATION of and comment on TERMINOLOGY:
cationic amphiphilic compound = cationic surfactant, namely, Surface-Active Agent, in this paper it is the
cationic surfactant tetradecyltrimethylammonium bromide (TDTMA); a new toxic effect of this chemical
was discovered. This chemical exemplifies a new type of hazardous contaminants (pollutants) of water.
Rotifers: Rotifers are an important part of the freshwater zooplankton, being a major foodsource
and with many species also contributing to the decomposition of soil organic matter. Most rotifers
are around 0.1–0.5 mm long , and are common in freshwater environments throughout the
world. The word "rotifer" is derived from a Latin word meaning "wheel-bearer", due to the corona
around the mouth that in concerted sequential motion resembles a wheel (though the organ does
not actually rotate). The coronal cilia create a current that sweeps food into the mouth. Rotifers eat
particulate organic detritus, dead bacteria, algae, and protozoans. They eat particles up to 10
micrometres in size. Like crustaceans, rotifers contribute to nutrient recycling. For this reason, they
are used in fish tanks to help clean the water, to prevent clouds of waste matter.

EXPLANATION of the terminology: pellets are the particles of undigested matter (mainly
biomass of undigested food) that the mollusks (the great pond snails and freshwater mussels)
excrete so that these mollusks function as engines that drive the transfer of a significant
amount of organic matter.
NOVELTY:
First measurements of concentrations of some chemical elements (C, N, P, Si, and Al) in the pellets of
aquatic mollusks. The first measurements of the biogeochemical fluxes of those elements with the
pellets. A discovery of a new type of geochemical fluxes of chemical elements in the biosphere: the
vertical (downward) flux of the elements toward the bottom of freshwater ecosystems, via pellets of
bivalves (freshwater mussels, Unio sp. and other species).

Abstract
Generation of membrane potential (delta psi) and transmembrane pH difference (delta pH) was studied in PPienergized chromatophores of Rhodospirillum rubrum by means of measurements of carotenoid and
bacteriochlorophyll absorption changes, atebrin and 8-anilinonaphthalene-1-sulphonate fluorescence
responses, and phenyldicarbaundecaborane transport. The data obtained are consistent with the suggestion
that carotenoid, bacteriochlorophyll and phenyldicarbaundecaborane responses are indicators of delta psi,
while an atebrin response is an indicator of delta pH. The fluorescence of 8-anilinonaphthalene-1-sulphonate is
affected both by delta psi and delta pH.
