Molluscs in biogeochemical flows (C, N, P, Si, Al) and water self-purification: effects of surfactants. — Vestnik MGU. Ser. 16. Biology. (ISSN 0201-7385; ISSN 0137-0952) 2003. No. 1. P. 15-24. [In collaboration: S.A.O., Kolesnikov M.P.] [The effects of a cationic surfactant on the feeding rate and the pellet excretion by the molluscs Lymnaea stagnalis and freshwater mussels (Unionidae) were studied. It is shown that the molluscs Lymnaea stagnalis excret pellets of faeces at the rate of 4-7 mg (dry weight) per 1 g of the wet weight of molluscs per 72 h. Under the conditions when the food is the leaves of Nuphar lutea, the content of C in the pellets was 69.74%; N, 2.3-2.9%; P, 0.4-0.5%; Si, 1.1-1.7%, Al, 0.054-0.059%. In the presence of the cationic surfactant, tetradecyltrimethylammonium bromide (TDTMA) (2 mg/L), the feeding rate of molluscs was decreased by 27.9-70.9%. Under the effect of the cationic surfactant, TDTMA (2 mg/L), the production of pellets per g of the wet weight of molluscs was decreased by 41.7% (over the incubation period of 72 h). We also studied the content of the pellets of freshwater mussels after their feeding on the natural seston (the sample of mussels taken from the natural community). In the sample, the species and their percentages were: Unio tumidus 63.21%, U. pictorum 27.36 %, Crassiana crassa 7.55 %, Anodonta cygnea 1.89 %. This sample of bivalves produced the pellets that had the following chemical content: C, 64.3%; N, 2.73%; P, 0.39%; Si, 1.14%; Al, 0.071%. Water filtering by the unionids was also inhibited by TDTMA and some other surfactants. Therefore it was shown that the surfactant inhibited the matter and elements transfer through this level of the trophic chain].
Some approaches to the system of criteria for environmental hazards of man-induced effects on organisms and ecosystems. - Siberian Ecological Journal.. 2003. No.2: , p. 247-253. [ = Siberian Journal of Ecology = Sibirskiy ekologicheskiy zhurnal; ISSN 0869-8619; http://www.sibran.ru/English/SECJE.HTM ] [The paper provides a critical discussion of the classification criteria for environmental hazards which is used in some states - e.g., the states of EC (European Community), in order to decide in what classification category a substance will fit. A new system of criteria for environmental hazards is proposed. The system includes four blocks according to the four levels of man-caused disturbances in living systems. As an example of a non-lethal but potentially important effect produced by a man-made chemical, some new data on the inhibitory effects of a surfactant on bivalves are presented. A non-ionic surfactant Triton-X100 inhibited the water filtration by mussels. Various ecologically important consequences of the inhibition of water filtration are discussed. The efficiency of the proposed system of criteria is demonstrated]. http://www.sbras.ru/PSB/show_text. phtml?eng+1646+9. Russian version of the paper: http://scipeople.com/publication/70334/;

Studying effects of some surfactants and detergents on filter-feeding bivalves. --Hydrobiologia. 2003. 500: 341-344. [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. Inhibition of filtering activity as a result of the effects of surfactant TDTMA 0.5 mg l-1 on the oysters Crassostrea gigas; SDS 0.5 mg l-1 on C. gigas;3 synthetic detergent mixtures on Mytilus galloprovincialis and C. gigas.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, 2000, 2001). This experimental approach is helpful in assessment of environmental hazards from man-made chemicals that can contaminate marine systems].

New type of action of potentially hazardous chemicals: uncouplers of pelagial-benthal coupling (Novyi tip deistviya potentzialno opasnykh veshchestv: razobshchiteli pelagialno-bentalnogo sopryazheniya). — DAN. 2002. v. 383. No.1 p. 138-141. [The effects of the xenobiotic (potassium bichromate K2Cr2O7) on the removal of suspended matter from water by the mussels Mytilus galloprovincialis was studied. It was shown that the chemical inhibited the removal of suspended matter from water during water filtering by mussels. It was concluded that the chemical inhibited water filtration rate by themussels. The results are in accord with previous findings on effects of other xenobiotics and pollutants on filtration rate by bivalves. The similar inhibition by xenobiotics and pollutants was shown by the author for both marine (Ostroumov, DAN, 2001, vol. 378, No. 2., p. 283-285) and freshwater (Ostroumov, DAN, 2001, vol. 380, No. 5., p. 714-717) molluscs. The results demonstrate a new type of ecological hazard from water pollution when the polluting chemicals may uncouple the link between from the pelagial part of the ecosystem and its benthal part, i.e. pelagial-benthal coupling].

Distributed by Springer, orderdept@springer-sbm.com. As a result of the author’s studies of filter-feeders (DAN, 1998, Vol. 362, P. 574-576; 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).].

[In 1935, the term 'ecosystem' was coined by A. Tansley. In the 1940s, another important term 'biogeocoenosis' was introduced by V. N. Sukachev. Since that time, a significant amount of new facts was accumulated in ecology. It is necessary to revisit the formulation of the basic concepts and terms in ecology, including the two terms mentioned above. The author proposed some new variants of the definition of the two terms that (1) reflect the modern vision of the basics of ecology; and (2) avoid the vicious circle of using other terms that in turn request their definitions.

Inhibitory analysis of top-down control: new keys tostudying eutrophication, algal blooms, and water self-purification. — Hydrobiologia. 2002. Vol. 469, P.117-129. Full text free: http://ru.scribd.com/doc/52598579 Top-down control is a vital type of interspecies interactions in food webs. Phytoplankton grazers contribute to the top-down control of phytoplankton populations. This article is focused on the role of benthic suspension-feeders (filter - feeders) in the control of plankton populations as a result of water filtering and the removal of suspended matter (including the cells of plankton) from the water column. New data on the inhibitory effects of synthetic surfactants and detergents on bivalves, which are benthic filter-feeders (freshwater mussels Unio tumidus, U. pictorum, marine mussels Mytilus galloprovincialis, M. edulis, and oysters Crassostrea gigas) are presented and discussed. Importance and efficiency of that approach to the problems of eutrophication and water self-purification is pointed out. The chemical pollution may pose a threat to the natural top-down control of phytoplankton and water self-purification processes. Water self-purification is a key prerequisite for sustainable use of aquatic resources. The anionic surfactant SDS at a concentration of 0.5 mg/L inhibited water filtration by C. gigas, at a concentration of 1.7 mg/L suppressed the filtering activity of M. galloprovincialis, at that of 1-5 mg/L decreased water filtration by M. edulis. The non-ionogenic surfactant TX100 at concentrations 0.5-5 mg/L induced a sharp slowdown in water filtration by M. edulis, at 1 and 5 mg/L it caused a decrease in the filtration rate by the freshwater bivalve U. tumidus. The cationic surfactant TDTMA at 1-2 mg/L constrained the filtering activity of the freshwater bivalve U. pictorum. 4 detergents (6.7-50 mg/L) hindered the filtration by M.galloprovincialis. 3 detergents (1-30 mg/L) slowed down the clearance rate during water filtration by C. gigas. The shampoo AHC (Avon Herbal Care) at concentrations 5-60 mg/L arrested the filtration by M. galloprovincialis.

ISSN 0018-8158 (Print) 1573-5117 (Online) [Selected elements of a new vision of the role of biodiversity in water purification and maintaining the natural purification potential of ecosystems, elements of the theory of water self-purification. 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 impairment of the second type].DOI 10.1007/s10750-004-1875-1; http://www.springerlink.com/content/hcrfvmdncdm8e3pf/; http://scipeople.com/uploads/materials/4389/2H469p203.Polyfunctional.role.w.Addendum.rtf;
Identification of a new type of hazard of chemicals: inhibition of processes of ecological remediation. – DAN. 2002. Vol. 385. No. 4. P. 571-573. [New data on the inhibition of filter-feeders by chemical mixtures (detergents) are reported. The detergent Lanza-Automat (20 mg/L) inhibited water filtration by the bivalves (oysters) Crassostrea gigas (incubation time 4-35 min, 23.4ºC). As a result, the removal from water of suspended cells of Saccharomyces cerevisiae was inhibited by the detergent. New data are in line with the previous findings of the same author on the similar action of other detergents as well as surfactants (e.g., Ostroumov, 2000, 2001). The author formulated and substantiated a new conceptualization of ecological hazards from chemicals that pollute aquatic environment. The author proposed that the ability of bivalves to contribute to water purification and ecosystem remediation may be damaged by chemical pollutants exemplified by detergents. The concept is in accord with the conclusions made on some other studies of the same author using bivalves Unio tumidus (DAN, 1991, 380:714-717); Mytilus edulis (DAN, 1998, v.262: 574-576) and C. gigas(DAN, 2001, v. 378: 283-285)].

Identification of a new type of ecological hazard of chemicals: inhibition of processes of ecological remediation. Doklady Biological Sciences. 2002. 385: 377-379. Full text free: http://www.scribd.com/doc/45911150; ISSN 0012-4966 The author discovered and characterized a new type of ecological hazard of chemical pollution of water, which involves inhibition of important processes of ecological remediation of ecosystems (water filtration by aquatic bivalves). Experiments were performed using mollusks (oysters), Crassostrea gigasThunberg, and a cell suspension of Saccharomyces cerevisiae. The cell suspension was a model of suspended matter in aquatic ecosystem. Laundry detergent Lanza-Automat inhibited water filtration by oysters C. gigas. As a result, the removal of the cells (S. cerevisiae) from water was inhibited. This demonstrated a new type of ecological hazard caused by water pollution with chemical pollutants at sublethal concentrations.

[=Effetti dell' attività umana sul biota: verso un nuovo sistema di principi e criteri per l'analisi dei rischi ecologici. 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’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.

Aquatic organisms as a factor in the regulation of the flows of matter and migrations of chemical elements in aquatic ecosystems.- Izvestija Samarskogo nauchnogo centra Rossijskoj akademii nauk, 2003, v.5, No.2, p.249-255. Bibliogr. 24 refs. [V.I.Vernadsky underlined the important role of the living matter in determining the pattern of migrations of chemical elements on the surface of Earth, including the hydrosphere. On the basis of the data accumulated in hydrobiology, limnology, and biological oceanography, some conceptual conclusions could be made. The classification of migrations of elements, as proposed in this paper, can include the following types: vectorial and stochastic, cyclic and non-cyclic migrations. The role of living matter in regulation of that which proportion of matter (chemical elements) undergo any of those types of migrations is analyzed. Author consider both groups of factors (biotic and abiotic ones) as important in that regulation. The structurization of the migrations of chemical elements on the surface of Earth is under the combined and complex control of the both groups of the factors. Extending the area of usage of the unique adjective proposed by Vernadsky (‘biocosny’, which means formed as a process and result of the combined and closely interwoven action of biotic and abiotic factors; the adjective consists of two parts, ‘bio’ and ‘cosny’, the latter means ‘inert’ in Russian and reflects the sum of abiotic factors), we consider the complex biocosny regulation of migrations of matter and chemical elements in the biosphere, including the regulation of dichotomies at the points of bifurcations among the vectorial and stochastic, as well as cyclic and noncyclic types of their migrations. The conceptual conclusions are based on the empirical data in literature and the results of our experiments (e.g., Ostroumov, Kolesnikov 2000, 2001; Ostroumov 2001)]. http://www.ssc.smr.ru/ftp/2003/ssc52249.pdf Full text is available at eLIBRARY, see: http://elibrary.ru/

[Using a cationic surfactant (tetradecyltrimethyl ammonium bromide) and heavy metals (Cd, Cu and some others), new experimental data were obtained that show that one of the most important processes of ecological repair of water quality (the process of removal of suspended matter by aquatic organisms) is inhibited by pollutants (xenobiotics), which points to some similarity or analogy with the processes of DNA repair; the latter can also be inhibited by some xenobiotics and have some other attributes (a decrease in entropy etc.) that are analogous to those of ecological repair. The xenobiotics that produced those negative effects on the processes of the ecological repair (remediation) of water quality included various surfactants, detergents, and metals.

Studying effects of some surfactants and detergents on filter-feeding bivalves. --Hydrobiologia. 2003. 500: 341-344. [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).

ISSN 0012-4966 (Print) 1608-3105 Welfare of the biosphere depends on filter-feeders that contribute to making water clean and transparent. Important new facts on the hazard of man-made damage to the beneficial function of rotifers, which are the plankton filter-feeders, were discovered. For the first time, it was found that a chemical pollutant inhibits filtration activity of rotifers. As a chemical pollutant, a representative of synthetic surfactants was studied. The study featured an advanced technique that allows a precise measurement of the filtration rate on the basis of measuring the rate of removal of algal cells from water by rotifers. The experiment was run in the following system: the two-species culture of rotifers (Brachionus calyciflorus) and algae (Nannochloropsis limnetica; Eustigmatophyceae) was studied in a two-stage turbidostat (temperature 20°C) as described by Walz et al. (1997) with some modifications. Dilution rate (the higher the filtration activity of rotifers, the higher the dilution rate) was measured in the turbidostat. As a model of a chemical pollutant, the cationic surfactant tetradecyltrimethylammonium bromide (TDTMA) was added to the water of the turbidostat. On the basis of previous studies (Ostroumov, 2000), the concentration of TDTMA was 0.5 mg/L. Dynamics of the dilution rate before and after addition of the chemical was monitored. The dilution rate decreased after the addition of TDTMA. Also, a comparison of the dilution rate in the experimental turbidostat (with the surfactant) with the control turbidostat (without the chemical) was made. Under conditions of the presence of TDTMA the dilution rate was lower than in the control turbidostat. The lower dilution rate means a lower filtration and grazing activity of the population of the rotifers. The results are in accord with the hypothesis that the cationic surfactant TDTMA can inhibit the filtering activity of populations of rotifers. The results support the conclusions of previous publications, in which analogous effects of surfactants on another major group of filter-feeders (the bottom-dwelling bivalve mollusks) were discovered (Doklady of the Russian Academy of Sciences, 2001, 380, p. 847-849; 2002, vol. 382, p.138-141).

[The 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.
