WorldCat review of the article: Pellets of Some Mollusks in the Biogeochemical Flows of C, N, P, Si, and Al. https://www.researchgate.net/publication/286780426
Explanation of methodology (some details on the choice of the biological species and chemicals to study). Why the great pond snail and freshwater mussels were studied in this reseach project: they are among the most common benthic species of invertebrates in water habitats of Eurasia. Their biomass is one of the biggest, or just the biggest, among aquatic invertebrates in Eurasia and other parts of the world. Why the plant species, Nuphar lutea (Yellow Water-lily) , was used in this research project: it is one of the most common aquatic plant species in the freshwater habitats of Eurasia. Why the plant species, Taraxacum officinale, was used in this research project: it is a common laboratory practice to feed the great pond snail with leaves of this higher plant. Why the synthetic surfactants ТDТМА (tetradecyltrimethylammonium bromide) and SDS (sodium dodecyl sulfate) were used: they are representatives of the two major classes of synthetic surfactants, namely, cationic surfactants, and anionic surfactants. These two chemicals were studied in many other publications of Dr. Sergei Ostroumov, so that lots of data to compare toxic effects of these chemicals on organisms are available. A detailed explanation of methodology was also published in the book Biological Effects of Surfactants (Ostroumov, 2005, https://www.researchgate.net/publication/200637626)

Comment on the biological species that were studied in this paper: the great pond snail is a species of large air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae. Range Description: A widespread species distributed in Asia (central, north and south and southeast), north America, north Africa and New Zealand. The great pond snail has a shiny yellowish brown shell.
Nuphar lutea (Yellow Water-lily) is an aquatic plant of the family Nymphaeaceae, native to temperate regions of Europe, northwest Africa, and western Asia.
Unio is a genus of medium-sized freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels. Unio is the type genus of the family Unionidae. About this family: The range of distribution for this family is world-wide. It is at its most diverse in North America, with about 297 recognised taxa, but China and Southeast Asia also support very diverse faunas. Freshwater mussels occupy a wide range of habitats, but most often occupy lotic waters, i.e. flowing water such as rivers, streams and creeks.
Explanation of terminology: pellets are the particles of the undigested organic matter (mainly biomass of undigested food) that the aquatic mollusks (snails and freshwater mussels) excrete so that these mollusks function as engines that drive the transfer of a significant amount of the organic matter through aqautic ecosystems.

Abstract: An aquatic ecosystem: a large-scale diversified bioreactor with a water self-purification function. — Doklady Biological Sciences, 2000. Vol. 374, P. 514-516. 3 tables. Bibliogr. 15. ISSN 0012-4966. Distributed by Springer, orderdept@springer-sbm.com. ** Innovative conceptualization: The author developed a new fundamental concept of aquatic ecosystem as a multi-functional bioreactor. One of the key functions of that bioreactor is upgrading water quality via a multi-component biomachinery of water self-purification. ** New facts: Contribution of the main groups of aquatic organisms (heterotrophic bacteria, fungi, cyanobacteria and microalgae, protozoans, higher plants, invertebrates, fish and amphibians) to water self-purification: comparison and analysis (Tabl.1). Relatively small effects of a synthetic non-ionic surfactant (Triton X-100 or TX100, 4-5 mg/L) on marine bacteria Hyphomonas sp. MHS-3 (5 mg/L), and on bacteria Hyphomonas sp. VP-6 (5-10 mg/L), a significant inhibition by the synthetic surfactant Triton X-100 of the water filtration by the marine mussels Mytilus edulis (4 mg/L), and by the freshwater mussels Unio tumidus (5 mg/L). The negative (inhibitory) effects of a synthetic cationic surfactant TDTMA 1 mg/L on the marine mussels M. galloprovincialis (Tabl.2); the inhibition of feeding: effects of the synthetic surfactant TX100 1-5 mg/L on the freshwater mussels Unio tumidus, inhibitory effects of the synthetic surfactant TDTMA 1-2 mg/L on the freshwater mussels U. pictorum; effects of a number of synthetic surfactant and detergents, namely, TDTMA 1 mg/L, anionic surfactant SDS 1.7 mg/L, detergents 6.7 – 50 mg/L, shampoo (namely, the shampoo) AHC 5-60 mg/L (sublethal concentrations) on the marine mussels M. galloprovincialis; TX100, TDTMA (2 mg/L), laundry detergent (Tide-Lemon, 75 mg/L) on the freshwater mollusk (the pond snail Lymnaea stagnalis) (Tabl.3).
** A fragment of the text: "Sublethal concentrations of contaminants may inhibit vital activities of other organisms involved in the function of an ecosystem as an analogue of a bioreactor. This finding provides a deeper insight into the mechanisms of anthropogenic impact on biosphere. The concept put forward in this work emphasizes that intactness of the whole range of biological diversity of hydrobionts [aquatic organisms] is required to provide effective functioning of an ecosystem as an analog of a water self-purification bioreactor. Therefore, the monetary cost estimates of ecosystems and the biota should be increased" (p. 516).

Abstract: The author identified a new type of ecological hazard of anthropogenic impact (using chemical pollution as an example), which he proposed to term “synecological summation” or “synergistic summation” of anthropogenic effects on organisms of two adjacent trophic levels. ** NEW FACTS: in the study reported in the paper, the following new type of environmental hazards was found. It was shown that even some relatively mild influences on organisms of two adjacent trophic levels may eventually produce a synergistic, pronounced and definitely undesirable effect which will lead to an abnormal increase in the abundance of organisms of one of the trophic levels. The concrete examples of that type of synergism were found when anthropogenic impacts affected the organisms of two adjacent trophic levels (bivalves and algae). Some new bioeffects of the action of the synthetic detergent (exemplified by the laundry detergent, namely, the detergent 'Vesna') (1 mg/l) on the bivalves, oysters Crassostrea gigas were described. Also, some new effects of the detergent (exemplified by the laundry detergent, namely, the detegent 'IXI') (10 mg/l) on the marine mussels Mytilus galloprovincialis, were found; also, new effects of the detergent (exemplified by the laundry detergent, namely the detergent 'Tide-Lemon') (50 mg/l) on M. galloprovincialis were discovered. ** CONCLUSION: The hazard of simultaneous influence of contamination of environment (e.g., by detergents) on organisms of the two trophic levels may occur when the polluting chemicals produce effects on algae and bivalves that are filter-feeders. It means that a new type of environmental hazards was discovered.

Abstract: Responses of the freshwater bivalve Unio tumidus to mixed chemical preparations and the hazard of synecological summation of anthropogenic effects. - Doklady Biological Sciences, 2001, Volume 380, 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 (e.g. effects of the laundry detergent OMO on the freshwater mussels Unio tumidus) were discovered and 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;

Full text, free, is available online, of this article: Biodiversity protection and water quality: the role of feedbacks in ecosystems. https://www.researchgate.net/publication/259497389;
ABSTRACT: The article presents a new fundamental concept of how biodiversity helps towards a better environmental stability and water quality. The author made an innovative analysis of his experimental data and formulated the following fundamental principle: to maintain water quality, it is vital to protect the functionally active biodiversity of water ecosystems. In other words, according to the author’s new concept, the protection of functionally active biodiversity, including filter-feeders, is a key to maintenance of water quality. This concept was supported by many facts obtained in experiments of the author and reported in his previous publications. This article presents new facts in support of his concepts. Among new facts obtained and reported in the paper: a chemical pollutant (exemplified by the laundry detergent IXI, at a sublethal concentration 20 mg/L) inhibited water filtration by the aquatic bivalve mollusks, marine mussels Mytilus galloprovincialis (3-25 min, 18 pro mille, 22.8ºC). Another synthetic detergent (exemplified by the laundry detergent Deni-Automat), at a sublethal concentration 30 mg/L, also inhibited the water filtration by the marine bivalves oysters Crassostrea gigas (2-40 min, 25.2ºC).]. These new data as well as the other related data obtained by the same author and reported in his other publications, supported the author’s fundamental concept.

ABSTRACT: System of principles for conservation of the biogeocenotic function and the biodiversity of filter-feeders.- Doklady Biological Sciences. 2002. Vol. 383: 147-150. Bibliogr. 15 refs. ISSN 0012-4966 (Print) 1608-3105 (Online). Distributed by Springer, orderdept@springer-sbm.com. ** Text of the ABSTRACT: As a result of the author’s studies of filter-feeders (previous publications in Russian: Doklady akademii nauk [DAN], 1998, Vol. 362, P. 574-576; Doklady akademii nauk [DAN], 2001, Vol. 378, P. 283-285), it is clear that the filtering activity of populations of filter-feeders in natural habitats might be significantly reduced if the concentrations of some pollutants reach certain levels. The role of filter-feeders as factors of water purification in ecosystems is so important that their inhibition is a danger for the entire ecosystem. The author emphasizes that not only the biodiversity of filter-feeders but also their level of functional (filtration) activity is to be protected. In order to do so, the author suggested establishing a new type of protected areas whose main purpose is to protect functionally active populations of filter-feeders, including bivalves and other organisms. Those protected areas could be named hydrobiological (some variants: biofiltering, or malacological) reserves (some variants: refuges, sanctuaries, etc.). The author formulated 5 principles of nature conservation requirements in malacological and hydrobiological reserves (Tabl. 3). Among them is principle 2, "conservation of filtration activity of organisms and populations". The paper contains data on how 5 detergents (1-50 mg/L) inhibited the filtration activity of Unio tumidus, Mytilus galloprovincialis, Crassostrea gigas (Tabl. 2); on effects on the efficiency of elimination (EEE) of suspended matter from water were measured (Tabl. 2); on the number of days (0.3 – 10) needed to filter the volume of aquatic (freshwater and marine) ecosystem by the local bivalves (a review of data from literature) (Tabl. 1). "I suggest that the existing system of protected terrestrial and water areas should be supplemented with special sites intended to conserve populations of filter-feeders. In addition to biodiversity conservation, these populations should be conserved because they fulfill a very important biogeocenotic function of water filtration and purification" (p.149). "The system of five principles…is proposed to provide an ecological basis of the environment conservation conditions at these sites (malacological and hydrobiological reserves)" (p.149).].
