Abstract:
Ostroumov S. A., Kolesov G. M. The aquatic macrophyte Ceratophyllum demersum immobilizes Au nanoparticles after their addition to water. - Doklady Biological Sciences, 2010 (Mar - Apr), Vol. 431, p. 124–127. [© Pleiades Publishing, Ltd., ISSN 0012-4966]. Original Russian Text © S.A. Ostroumov, G.M. Kolesov, 2010, published in Doklady Akademii Nauk, 2010, Vol. 431, No. 4, pp. 566–569. Bibliogr. 15 refs. Presented by Academician M.A. Fedonkin July 31, 2009. Received February 11, 2009. DOI: 10.1134/S0012496610020158. http://scipeople.com/publication/69766/. In the paper, it was discovered that the aquatic plant (macrophyte) Ceratophyllum demersum immobilized gold (Au) nanoparticles after their addition to water. This is the first time it was shown that the nanoparticles of gold (Au) in substantial amount bind to the living biomass of the aquatic macrophyte, Ceratophyllum demersum. The concentrations of Au were measured in the samples of the phytomass using neutron activation analysis (NAA). As a result of the binding and/or immobilization of the nanoparticles, the amount of Au in the samples of the phytomass increased manifold (by a factor of 430) above the background level of gold in the plant tissues. The increase was by two orders of magnitude. The new data added some new information to the modern vision of the multifunctional role of the biota in the migration of elements in aquatic ecosystems. Also, the result added new information to the studies of interactions of Au with organisms that may contribute to new biotechnologies. http://www.ncbi.nlm.nih.gov/pubmed/20506851; PMID: 20506851 [PubMed]; http://www.springerlink.com/content/j487667871w02h28/; www.springerlink.com/index/J487667871W02H28.pdf;

Abstract:
Fundamental elements are formulated for a new qualitative theory of the multifunctional (polyfunctional) role of the biota in improving water quality and doing self-purification of water in aquatic ecosystems. The elements of the theory covers the following: sources of energy for the mechanisms of water self-purification; the main functional blocks of the system of self-purification; the system of the main processes that are involved; the analysis of the degree of participation of the main large taxa; the reliability of the mechanisms of water self-purification; regulation of the processes; the response of the mechanisms of water self-purification towards the external influences (man-made impacts, pollution); and some conclusions relevant to the practice of environment protection. In support of the theory, the results are given of the author's experiments which demonstrated the ability of some pollutants (surfactants, detergents, and some others) to inhibit the water filtration activity of marine filter-feeders, namely, the bivalve mollusks Mytilus galloprovincialis, Mytilus edulis, and Crassostrea gigas.

Abstract
Ostroumov S. A., Walz N., Rusche R. Effect of a cationic amphiphilic compound on rotifers. - Doklady Biological Sciences. 2003. Vol. 390. p.252-255, Full text online free: http://www.scribd.com/doc/52634169/; https://www.researchgate.net/file.FileLoader.html?key=74bb403b372f3adc298aacbef568b0ee; [ISSN 0012-4966 (Print) 1608-3105 (Online)]. 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. In this paper, it is the first time that 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 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 monitored 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 addition 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, pp. 847-849; 2002, vol. 382, pp.138-141). www.springerlink.com/index/R3126462K122M13T.pdf; DOI10.1023/A:1024417903077; Key words: effects, cationic amphiphilic substance, rotifers, two-species culture, rotifers Brachionus calyciflorus, algae Nannochloropsis limnetica, turbidostat, filtration activity, cationic surfactant tetradecyltrimethylammonium bromide TDTMA, grazing activity, filtering activity of populations, filter-feeders, chemical pollution, effects of pollutants, sublethal concentration, trophic interactions, man-made effects, anthropogenic,

The hazard of a two-level synergism of synecological summation of anthropogenic effects. - Doklady Biological Sciences, 2001, Volume 380, Numbers 1-6, p. 499-501. 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 Vesna (1 mg/l) on the bivalves, oysters Crassostrea gigas were described. Also, some new effects of the detergent IXI (10 mg/l) on the mussels Mytilus galloprovincialis, were found; also, new effects of 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.

ISSN 0012-4966 (Print) 1608-3105 (Online). 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 (detergent OMO, freshwater mussels Unio tumidus) were studied. These detergents inhibited water filtration by the bivalve mollusks Unio tumidus. 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;

Ostroumov S.A. Imbalance of factors providing control of unicellular plankton populations exposed to anthropogenic impact. - Doklady Biological Sciences, 2001. Vol. 379, P. 341-343. 4 tables. Bibliogr.12 refs. (Translated from DAN 2001. Vol. 379. P.136-138). ISSN 0012-4966 (Print) 1608-3105 (Online). PMID: 12918370 [PubMed - indexed for MEDLINE]. The paper presents and analyzes new experimental data on the effects of chemical pollution of aquatic medium on the abundance of unicellular plankton organisms. The following 6 types of effects of filter-feeders and chemical pollutants [surfactants and detergents (mixtures)] on phytoplankton organisms were found (examples were given in this paper in Tab.2): (1) Inhibition of growth (and abundance); (2) Growth stimulation in the presence of surfactants and detergents; (3) Decrease in abundance as a result of elimination of plankton cells from water by the freshwater mollusks Unio tumidus and rotifers; (4) Abundance decrease as a result of water filtration by the marine mollusks Mytilus edulis, M. galloprovincialis, and Crassostrea gigas; (5) Decrease in the efficiency of cell elimination from water caused by the TX-100-induced (5 mg/l) inhibition of the filtration activity of the freshwater mollusks U. tumidus; (6) Decrease in the efficiency of cell elimination from water as a result of inhibition of the filtration activity of the marine mollusks Mytilus galloprovincialis and Crassostrea gigas induced by surfactants and Avon Herbal Care (hair shampoo). A new parameter and formula is suggested: the efficiency of cell elimination from water, ECE. The following maximum values of ECE were found (at the concentrations of the chemical, mg/l, in brackets): (1) Detergent OMO, Unio tumidus, 186.7 (50); (2) Detergent Losk-Universal, Mytilus galloprovincialis, 551.7 (7); (3) Detergent Tide-Lemon, Mytilus galloprovincialis, 206.9 (50); (4) Detergent IXI, M. galloprovincialis, 157.8 (10); (5) Detergent Deni-Automat, Crassostrea gigas, 10 800.0 (30); (6) Detergent Lanza, Crassostrea gigas, 261.7 (20); (7) Detergent Vesna-Delikat, Crassostrea gigas, 200.0 (1); The tables in the paper: Factors of regulation of unicellular plankton abundance (Tab.1); effects of surfactants and detergents on phytoplankton abundance (Tab.2); 7 detergents inhibit filtration of 3 species of marine and freshwater molluscs (Tab.3); Mytilus galloprovincialis eliminates from water the cells of Saccharomyces cerevisiae and algae Pavlova lutheri = M. lutheri as a result of filtration (comparing the 2 processes at the same time, Tab. 4). The results obtained in this work demonstrated and proved that certain pollutants might cause a substantial imbalance of the factors controlling unicellular plankton populations. Direct and indirect (mediated by organisms-consumers) effects of certain surfactant-containing mixtures on unicellular plankton could sum with each other, giving rise to mutual amplification. This may cause a complete imbalance of the system. The conclusions made in this work may be applied to unicellular plankton of both marine and freshwater ecosystems, including ecosystems subjected to eutrophication. The results contribute to issues of environmental safety and resource use sustainability. DOI 10.1023/A:1011600213221; www.springerlink.com/index/QGJ756467J2R7470.pdf

ABSTRACT: Effects of amphiphilic chemicals on filter-feeding marine organisms. S.A.Ostroumov
For the first time, oysters were used as the test-organisms in bioassay of synthetic surfactants. As surfactants are one of key components of water pollution from municipal waste waters, from ports and ships, the new data revealed a novel type of hazard to mariculture of oysters. New negative effects of several amphiphilic chemicals (surfactants) and chemical mixtures on oysters and other marine bivalves were discovered. An anionic surfactant, sodium dodecylsulphate (SDS), and a cationic surfactant, tetradecyltrimethylammonium bromide (TDTMA) inhibited water filtering activity of oysters (Crassostrea gigas). Similar effects were exhibited by some chemical mixture products (detergents) that included surfactants as components of the mixtures. Those mixture products inhibited filtering activity by Crassostrea gigas and Mytilus galloprovincialis. The mixture products tested were: the SD1(L), Lanza-automat (Benckiser); SD2(I), IXI Bio-Plus (Cussons); LD1 (E), dish washing liquid E (Cussons International, Ltd.); and LD2 (F), dish washing liquid Fairy (Procter & Gamble, Ltd.). 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. The filtering activity contributes to improving water quality. This experimental approach is helpful in assessment of environmental hazard from man-made chemicals that contaminate marine ecosystems.

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.

Translated from Doklady Akademii Nauk, Vol. 385, No. 4, 2002, pp. 571–573. 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 gigas Thunberg, 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 (Crassostrea gigas). As a result, the removal of the cells (Saccharomyces cerevisiae) from water was inhibited. This demonstrated a new type of ecological hazard caused by water pollution with chemical pollutants at sublethal concentrations. This hazard is associated with the fact that chemical pollution of water causes inhibition of the physiological activity of filter-feeders, thereby inhibiting the important ecological processes of water filtration. These ecological processes contribute significantly to improving water quality, water purification and the related remediation of aquatic ecosystems (their ecological repair). ---http://scipeople.ru/users/2943391/; [http://www.springer.com/life+sci/journal/10630] also see: http://sites.google.com/site/bioeffectsofsurfactants/ http://sites.google.com/site/surfactantinhibitfilterfeed02/ http://sites.google.com/site/3surfactantsfiltrationmytilus/ http://sites.google.com/site/ostroumovsergei/ http://sites.google.com/site/bioticupgradewaterquality2008/

ABSTRACT:
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. The author realizes that the new variants of the terms cannot be ideal and some other variants of the definitions are also possible. 5 specific features of the proposed definition of ecosystem (Table 1). 8 specific features of the proposed definition of biogeocenosis, and 8 distinctions between the proposed definition and the classical definition by V.N.Sukachev (Table 2)].

Abstract:
Abstract. The paper presents a discovery of a new type of negative impact of pollutants on the biosphere, as a result of inhibition of water filtration by filter-feeders / suspension feeders. The water filtration and associated removal of suspended matter from water is part of migration of matter. As V.I. Vernadsky stressed, organisms are mediators of “biogenic migration of atoms in the biosphere”. This migration is partly implemented in the framework of pelagial–benthal coupling via the activity of filter-feeders, which remove the organic suspended matter from water and excrete pellets. The tables contains the following data: the average percentage of assimilated (16-90%) and non-assimilated (10-84%) food matter for 15 large taxa of invertebrates (Table 1); chromium (potassium bichromate) inhibited water filtration by mussels Mytilus galloprovincialis (Table 2); surfactants, detergents, pesticides inhibited filtration by filter-feeders, marine and freshwater bivalves and rotifers (Table 3). A prediction was made: "Further research and experimental studies are expected to provide new evidence that sublethal concentrations of chemical pollutants induce a significant decrease in the filtration capacity of freshwater and marine filter feeders" (p.129). "The uncoupling process considered above is an anthropogenic violation of two basic laws (empirical rules or biogeochemical principles) of the biosphere functioning: (1) biogenic migration of atoms of chemical elements in the biosphere always tends toward its maximum expression; (2) on the geological time scale, the evolution of species gives rise to the forms of life that are stable in the biosphere, and is so directed that the biogenic migration of atoms in the biosphere increases" (p.129).];Ostroumov S.A.

ABSTRACT:
Ostroumov S. A. Biodiversity protection and quality of water: the role of feedbacks in ecosystems. - Doklady Biological Sciences. 2002 (January). Volume 382, Numbers 1- 6, p. 18-21. The article presents a new vision of how biodiversity helps towards better stability and water quality. The author made an innovative analysis of his experimental data and formulated the following suggestion: to maintain water quality, it is vital to protect the functionally active biodiversity of water ecosystems. In other words, according to his vision, the protection of functionally active biodiversity, including filter-feeders, is a key to maintenance of water quality. Among new facts: the detergent IXI 20 mg/L inhibited water filtration by marine mussels Mytilus galloprovincialis (3-25 min, 18 pro mille, 22.8ºC); the detergent Deni-Automat 30 mg/L also inhibited the water filtration by oysters Crassostrea gigas Thunberg (2-40 min, 25.2ºC).].

It is the first paper in which a discovery of a new type of environmental hazards from chemical pollutants was made: namely, the hazards of a decrease in vital function of healthy aquatic ecosystems which maintain the proper level of cleanliness (purity) of water, and improve water quality It is the first paper in which it was clearly proved that the synthetic chemical, when it pollutes water, produces dangerous effects on both marine mussels and phytoplankton: it decreases water filtration rate by the mussels, and the normal control of abundance of phytoplankton by the marine mussels, the control which is associated with the filtration of water. ** 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. ** 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.

This paper gave a revolutionary new insight into the main functions and identity of ecosystem as a bioreactor to maintain water quality.
Paradigm shift (in other words, a big change in conceptual framework in that area of science) made by this paper:
This paper gave a revolutionary new insight into the main functions and identity of ecosystem as a bioreactor to maintain water quality.
Paradigm shift (in other words, a big change in conceptual framework in that area of science) made by this paper:
The conceptual framework Before this paper:
The primary function of ecosystems was thought to be: primary productivity;
The conceptual framework After publishing this paper:
It became clear that the primary function of ecosystems is not only primary productivity but also conditioning of their environment; in the case of aquatic ecosystems it is conditioning of aquatic environment, i.e. water self-purification.
Why it is important:
It is a contribution to scientific basis of water safety, water sustainability.
What happened afterwards, the further development in publications:
After publishing this article, the same author published a series of other papers with new data. The new papers confirmed the ideas and conclusions of this article. The references for the entire series of papers (plus a book, ‘Biological effects of surfactants’) are here:
EXAMPLES OF TEXTS (concrete sentences) IN WHICH MENTIONING THIS PAPER MAY BE PROPER AND USEFUL:
EXAMPLE 1. A new conceptualization of aquatic ecosystem was suggested in 2000, with an emphasis on the capability of an ecosystem (both freshwater and marine ecosystem) to purify water ( Ostroumov, 2000).
Or:
EXAMPLE 2. In 2000, a new concept was proposed which considered an aquatic ecosystem (both freshwater and marine ecosystem) as a bioreactor with the function of improving water quality (Ostroumov, 2000 ).
Or:
EXAMPLE 3. A contribution to theoretical discussion on what is ecosystem was made in 2000. In a paper focused on aquatic ecosystems ( Ostroumov, 2000 ), it was proposed to see aquatic ecosystem as a new type of bioreactor. The novelty of this type of bioreactor is in its structure and function. As for structure, it is a multi-species bioreactor. As for function, it is a bioreactor with a number of functions, one of them is improving water quality (water purification) (Ostroumov, 2000 ).
