Основные процессы, ведущие к очищению воды в водных экосистемах. Для формирования качества воды, ее очищения в водных экосистемах важны многие физические, химические и биотические процессы [1-3, 7, 13, 15]. Дополнив ранее опубликованный нами перечень процессов, предлагаем вариант основных из них (табл. 1). Многие из этих физических и химических процессов регулируются биологическими факторами или в определенной мере подвержены их воздействию. Например, масштабы сорбции загрязняющих веществ оседающими частицами взвесей зависят от концентрации клеток фитопланктона; фотохимические процессы разрушения веществ протекают при условии прозрачности воды, а прозрачность обеспечивается фильтрационной активностью гидробионтов. Таким образом, биотические процессы находятся в центре всей системы самоочищения воды. 2. Основные функциональные блоки системы самоочищения водных экосистем.

ВЕРНАДСКОГО © 2013 С.А. Остроумов, Московский государственный университет имени М.В. Ломоносова, биологический факультет; АННОТАЦИЯ: В статье представлены новые экспериментальные результаты автора по изучению взаимодействия ряда химических элементов с биогенным материалом из водных макрофитов. В экспериментах были получены новые данные по иммобилизации химических элементов биогенным материалом, полученным из водных макрофитов. Новые данные были проанализированы с учетом новых результатов в научной литературе. В результате, автор прокомментировал и дополнил некоторые концепции В. И. Вернадского в области учения о биосфере. Среди новых фундаментальных понятий, введенных автором: расширенная концепция биогенной миграции и иммобилизации химических элементов, а также новая типология основных видов вещества в биосфере. КЛЮЧЕВЫЕ СЛОВА: биосфера, загрязнение, иммобилизация, химические элементы, биогенный материал, Myriophyllum aquaticum, водная среда, наночастицы. НАЧАЛО ТЕКСТА СТАТЬИ: ВВЕДЕНИЕ. Исследования В.И. Вернадского [1] положили начало новому этапу в исследованиях биогеохимии и геохимической среды [2-29]. Значительное внимание уделялось накоплению новых фактов о содержании химических элементов в компонентах биосферы, о роли живых организмов в формировании параметров окружающей среды, о химико-биотических взаимодействиях [3-31]. В последние годы все большее значение приобретает также накопление новых данных о токсичности тех или иных химических элементов и их соединений, что стало актуальным ввиду нарастания опасностей загрязнения окружающей среды (на-пример, [5, 30, 32]). В.И. Вернадский в своих работах поднял ряд принципиально важных вопросов об организации биосферы и геохимической среды и выдвинул идеи, надолго определившие направления научного поиска. Среди таких вопросов следующие: 1) типология вещества в биосфере; 2) роль живого вещества в модификации окружающей среды; 3) биогенная миграция элементов [1]. Работами многих исследователей установлено, что биогенная миграция элементов [1-4] играет большую роль в формировании геохимической среды и элементного состава компонентов экосистем. Изучалась роль различных компонентов экосистем в миграции элементов, исследовался элементный состав биотических и абиотических компонентов окружающей среды [4, 5, 7-13]. Накоплены внушительные сведения о токсичности ряда химических элементов [4, 5, 10, 15]. Изучение количественных характеристик процессов и явлений, связанных с миграцией элементов, ... Об авторе: Остроумов Сергей Андреевич, доктор биологических наук, МГУ. Conclusions of the paper and the list of references, in the language of the original Russian publication: Новые факты о химико-биотических взаимодействиях в биосфере суммированы в таблицах 1-5 в публикации [9] и таблице 1 в данной работе. Новые элементы теоретических положений суммированы в таблице 6 в публикации [9] и в выводах публикаций [7-10]. Проведенная автором экспериментальная работа и анализ фактов позволяют сделать следующие комментарии о развитии следующих положений Вернадского. 1. Положение В.И.Вернадского о роли живого вещества как геологической силы, влияющей на лик Земли. Анализируя современное развитие этой концепции, можно отметить следующее: это положение детализировано, подтверждено и усилено на новом эмпирическом материале, в том числе фактами о водных экосистемах и организмах, полученных автором и систематизированных в теории самоочищения воды [6, 20, 21, 23, 24, 35-38]. В частности, это положение усилено новыми фактами в области водной экологии и их обобщением в теории полифункциональной роли организмов в самоочищении воды [6, 20, 21, 23, 24, 35-38] 2. Концепция В.И.Вернадского – биогенная миграция элементов. Предложенный анализ с учетом экспериментов автора и данных литературы ведет к дополнению этой концепции. Вывод из проведенной работы: автор прогнозирует, что будет становиться распространенной следующая формулировка: биогенная миграция и иммобилизация элементов (подробнее в разделе 4 данной работы). 3. Концепция В.И.Вернадского – типология вещества в биосфере, которую Вернадский излагал в нескольких вариантах, не совпадающих друг с другом. Предложенный анализ с учетом опытов автора (и участников наших опытов и измерений): прогнозирует, что проведенная работа и продолжающиеся исследования ведут к дополнению последнего варианта типологии, принятой в последних итоговых публикациях Вернадского (подробнее в разделе 4 работы [9]). Автор прогнозирует, что будет распространяться новая типология вещества, в соответствии с которой выделяется живое вещество, косное вещество и третий тип вещества (экс-живое вещество или бывшее живое вещество) [7-10]. 4. Концепция В.И.Вернадского – аппарат биосферы. Вопросы регуляции аппарата В.И.Вернадским не были рассмотрены. Автор предлагает учитывать роль природных химических веществ, продуцируемых организмами, как экологических хеморегуляторов. Концепция экологических хеморегуляторов предложена и обоснована им в книге «Введение в биохимическую экологию» (М.: Изд-во Московского ун-та) [44]. 5. Практическое использование новых результатов способствует проводить следующее: более объективную и точную оценку антропогенных воздействий на окружающую среду, более осмысленный мониторинг химического загрязнения, совершенствование прогнозирования последствий загрязнения среды, укрепление научной базы технологий очищения водной среды и предотвращения загрязнения, сохранение качества воды и поддержание безопасности источников водоснабжения.

Остроумов С. А. Новый тип действия потенциально опасных веществ: разобщители пелагиально-бентального сопряжения // Доклады академии наук (ДАН) т. 283, № 1. С.138-141. https://www.researchgate.net/publication/306400294; РЕФЕРАТ: Изучено воздействие ксенобиотика (бихромата калия K2Cr2O7) на удаление взвешенного вещества из воды мидиями Mytilus galloprovincialis. Показано, что это вещество подавляло удаление взвешенного вещества из воды в ходе ее фильтрации мидиями. Сделан вывод, что это химическое вещество ингибировало фильтрацию воды мидиями. Эти результаты согласуются с предыдущими работами, в которых изучали воздействие других ксенобиотиков и загрязняющих веществ на скорость фильтрации воды двустворчатыми моллюсками. Сходное ингибирование ксенобиотиками и загрязняющими веществами было показано автором на морских (Остроумов, ДАН, 2001, т.378, No.2, с.283-285) и пресноводных (Остроумов, ДАН, 2001, т.380, No.5, с. 714-717) моллюсках. Статья содержит уникальную таблицу, суммирующую количественные данные о доле пищи, которая ассимилируется (и неассимилируется) представителями многих крупных таксонов водных беспозвоночных. Результаты показывают существование нового типа экологической опасности загрязнения вод, когда загрязняющие вещества разобщают связь между пелагиальной частью экосистемы и ее бентальной частью, т.е. пелагиально-бентальное сопряжение. Тем самым возникает угроза нарушения двух фундаментальных биогеохимических закономерностей, подчеркивавшихся В.И.Вернадским. ABSTRACT: Ostroumov S.A. New type of action of potentially hazardous chemicals: uncouplers of pelagial-benthal coupling // Published in: Doklady Akademii Nauk [DAN]. 2002. v.383. No.1. p.138- 141. Translated into English: A new type of effect of potentially hazardous substances: uncouplers of pelagial–benthal coupling. — Doklady Biological Sciences. 2002. Vol. 383: 127-130. Bibliogr. 15. ISSN 0012-4966. DOI 10.1023/A:1015385723150. The effects of a xenobiotic (potassium bichromate K2Cr2O7) on the removal of suspended matter from water by 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 mussels. 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. Organisms are mediators of “biogenic migration of atoms in the biosphere”. This migration is partly implemented in the framework of pelagial–benthal coupling. Tables: the quantitative data for the average percentage of assimilated (16-90%) and non-assimilated (10-84%) food matter for 15 large taxa of invertebrates (Table 1); potassium bichromate inhibited water filtration by Mytilus galloprovincialis (Table 2); surfactants, detergents, pesticides inhibited filtration by filterfeeders, marine and freshwater bivalves and rotifers (Table 3). A prediction is 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 the 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).

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: (I) 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.

Short description of the content of this article: Biologically-driven transfer of organic matter and chemical elements through a model aquatic ecosystem (a microcosm) was found to be inhibited by a chemical pollutant / contaminant: effects of a surfactant on aquatic mollusk, the pond snail ( Lymnaea stagnalis). In the title of this article the Latin name of this mollusk (pond snail) is mentioned; in this title it is spelled as Limnea stagnalis; however, a more correct spelling is Lymnaea stagnalis. Adetailed comment on this article is published online: http://5bio5.blogspot.com/2012/07/biocatalysis-of-matter-transfer-in.html ; Superconcise summary: A new discovery: a new type of environmental hazards from chemical pollutants (contaminants) as exemplified by surfactants and detergents was discovered in this article. Those chemicals inhibited the transfer of chemical elements which were in the pellets produced and excreted by the freshwater mollusks, namely, pond snails (Lymnaea stagnalis) . This discovery is Important as it is a substantial addition to what is known on chemical element transfer/movements in the environment. These facts are of serious interest to biogeochemistry.

For the first time, the quantitative assessment of the biogeochemical flows was made. Also, for the first time, it was discovered that a synthetic chemical may inhibit those flows. The pellet excretion by the gastropods Lymnaea stagnalis feeding on the phytomass of macrophytes (such as Nuphar lutea) was 4–7 mg dry weight per 1 gram wet weight of the mollusks per 72 h. Pellet sedimentation contributes to the vertical transfer of chemical elements in the ecosystem. The pellet composition depended on the species of the plants eaten by the mollusks. When the gastropods L. stagnalis feed on N. lutea, the pellets contain, in addition to organic and inorganic carbon, nitrogen (N, 2.3–2.9%), phosphorus (P, 0.4–0.5%), and silicium (silicon) (Si, 1.1–1.9%). The relative content of Si was 30% higher than in the food phytomass. The synthetic surfactant tetradecyltrimethylammonium bromide (TDTMA, 2 mg/L) inhibited the feeding rate of the mollusks and pellet production, their accumulation at the bottom of microcosms, and the matter transfer connected with this. The data obtained demonstrated a new aspect of the ecological hazard due to environmental pollution with TDTMA and other quaternary ammonium compounds at sublethal concentrations. According to the author’s opinion, other contaminants may also suppress pellet production, their accumulation at the bottom, and the matter transfer associated with that. http://scipeople.ru/users/2943391/; EXPLANATION: Why TDTMA? This synthetic surfactant was used by the author in his previous research projects with other species of Mollusca. The author had discovered its negative effects on feedeing rate of bivalve mollusks. On this basis, he continued using this chemical substance when he started a new project with the pond snails. Why this species, Lymnaea stagnalis? This species was taken for studies in this project because it is one of most common species of freshwater invertebrates. The biomass of this species per 1 square meter of the freshwater ecosystem (and the mass of their pellets) reaches significant numbers. Therefore their role in transfer of organic matter and chemical elements in the form ofexcreted pellets is very substantial. Why the leaves of Taraxacum were used in experiments? This is just a common practice among the researchers who work with the pond snails in laboratories to use the leaves of this plant species as food for these mollusks. http://sites.google.com/site/2000dbs373p397biocatallstag/; IMPORTANT NOTE: This paper was published in the journal which is often underestimated.

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.

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 water filtration performed by the molluscs Unio tumidus, U. pictorum, M. galloprovincialis and inhibition of feeding by Limnaea stagnalis emphasized the potential ecological hazard from sublethal concentrations of pollutants (including those exemplified by synthetic surfactants and detergents).

INTRODUCTION Priorities of ecological research include the further studies of ecosystem functioning (Ostroumov et al., [2003]) that include functioning towards water purification (the self-purification of water) in natural water bodies and streams. The self-purification of water in natural ecosystems is a complex group of processes which includes physical, chemical, and biological components (Sushchenya, [1975]; Alimov [ 1981], [2000]; Skurlatov, [1988]; Uhlmann, [1988]; Izrael, and Tsyban, [1989]; Ostroumov [1998], [2001], [2002b]; Wetzel [2001]). Although biological aspects of water self-purification are generally attributed to heterotrophic microorganisms, the other groups of organisms are also known to play a significant role in this process (Sushchenya, [1975]; Konstantinov [1979], Alimov [ 1981], [2000], Wallace, and Starkweather, [1985]; Vymazal, [1988]; Walz, [1995]; Monakov[1998]; Wetzel [2001]; also, Vinberg, [1973]; Bul'on, Nikulina, [1976]; Ivanova,[1976]; Khlebovich, [1976]; - cit. in Ostroumov, [2001]). The goal of this work was to analyze some data from the literature and our own experimental data on water self-purification under natural conditions and to formulate a fundamental concept of the aquatic ecosystem as an analog of a bioreactor (in a broad sense) that contributes to water self-purification mediated by main groups of aquatic organisms. This paper is based on some previous publications of the author (Ostroumov [2000c], [2001], [2002a]). 2. METHODS. The rate of water purification by macrozoobenthic filter feeders was measured experimentally as described earlier (Ostroumov [2001]). After the water sample had been kept with filter feeders for a certain time, the water filtration efficiency was monitored by the measuring the optical density of the suspension of unfiltered single - cell organisms that remained in the water column. The control samples of water were subjected to the same procedure of filtration, but without the contaminant (chemical) tested. Some other methods of the studies of the effects of contaminants on aquatic organisms are described in (Waterbury & Ostroumov [1994] , Ostroumov et al. [1997]). 3. ROLE OF THE MAIN GROUPS OF ORGANISMS IN THE BIOLOGICAL PROCESSES OF WATER PURIFICATION. Self-purification of water includes the following biological processes: (1) biodegradation of contaminants; (2) accumulation and sequestration of toxicants in aquatic organisms and the resultant removal of the toxicants from the water column (e.g. Vymazal, [1988]); (3) generation and emission of oxygen required for oxidative degradation of contaminants; (4) uptake of biogenic substances (including N and P) and organic substances from the aquatic environment; (5) production of exometabolites; (6) water filtration (Sushchenya, [1975]; Alimov [1981]; Wallace, and Starkweather, [1985]; Monakov [1998]); and (7) formation of pellet and detritus particles (e.g., Wotton et al. [1998]); and their sedimentation to the bottom (for review, see e.g., Konstantinov,[ 1979]; Ostroumov [1986], [1998], [2001], [2002b]; Skurlatov, [ 1988]). This list is far from complete, and some other biological phenomena simultaneously contribute to several processes listed above. Analysis of the relative contributions of individual groups of aquatic organisms to water self-purification as an integral function of an ecosystem (Table 1) shows that the main groups of organisms simultaneously contribute to several processes of the system of water self-purification. None of the main groups of aquatic organisms can be regarded as being insignificant in terms of water purification. The role of each group of aquatic organisms in these processes can be summarized as an integral ecological rating, which is calculated as the sum of the number of pluses in the corresponding row of Table 1. It is seen from Table 1 that this rating is sufficiently high in all groups of organisms. Thus, the whole range of biological diversity of aquatic organisms is an important factor in water self-purification (Sushchenya, [1975]; Alimov [1981, 2000], Wallace, and Starkweather, [1985]; Wotton et al. [1998]; Ostroumov [2001], Wetzel [2001]). The biota representatives of the water column, the entire ecosystem volume, the boundary regions of the ecosystem, and zones of contact between the ecosystem and its environment are involved in water purification. Activities of unicellular organisms (including those freely suspended in water, immobilized, and attached to various particles, surfaces, and substrates) (e.g., Inkina, [1988]) as well as of other aquatic organisms (e.g., Ostroumov [2001], Wetzel [2001]) suggest that an aquatic ecosystem may be regarded as a bioreactor (in a metaphorically broad sense; i.e., including biological, physical, and chemical aspects). However, unlike industrial bioreactors, such a broad-sense bioreactor has the following important features. 4. AQUATIC ECOSYSTEM AS A BIOREACTOR WITH SOME FEATURES. The first feature is a fundamental difference in the bioreactor size. The volume of technological bioreactors does not exceed a few hundred cubic meters, whereas the volume of natural ecosystems is significantly larger. For example, the volumes of lake and estuary ecosystems reach thousands of cubic kilometers: Lake Baikal, 22995 km 3 ; Lake Superior, 12221 km 3 ; Lake Michigan, 4871 km 3 ; Lake Issyk-Kul, 1730 km 3 ; Lake Ladoga, 908 km 3 ; Lake Onega, 280 km 3 ; Lake Balkhash, 112 km 3 ; and Lake Sevan, 38 km 3 ; (1 km 3 = 10 9 m 3 ). This increases the biospheric role of ecological, biochemical, and biofiltration processes in these systems. Therefore, the physical size and volume of the system within which water self-purification take place should be taken into consideration. Thus, natural ecosystems can be regarded as large-size (large-scale) analogues of bioreactors. The second feature is the differences (in terms of size and diversity) between the gene-pool of organisms inhabiting natural ecosystems and the genetic pool of organizms grown in technological bioreactors. This difference leads to a significantly larger diversity of functional activities of organisms in natural ecosystems. Technological bioreactors are usually inoculated with monocultures or, less frequently, mixed cultures with a small number of constituting species. In contrast to technological bioreactors, the biological diversity of natural ecosystems is substantially broader. According to some incomplete estimates, the number of species in natural ecosystems is as many as several hundred to several thousand (e.g., Konstantinov, [1979]). These estimates were obtained without regard to the number of strains of individual microbial species. If the prokaryote strains are taken into account, the quantitative estimates of the biological diversity of taxa in natural ecosystems may increase by several orders of magnitude. Third, an aquatic ecosystem is characterized by a higher degree of autonomy (including energy autonomy) than technological bioreactors. This autonomy is based on the presence of autotrophic organisms. Thus we suggest that natural ecosystems should be regarded as multispecies and diversified (i.e., based on the diversity of organisms and their functions) analogs of bioreactors, implementing a broad spectrum of catalytic functions (including transformation and degradation of contaminants). 5. MAN-MADE EFFECTS AND THE EFFECTS OF SOME XENOBIOTICS. Anthropogenic sublethal effects (including the inhibition of physiological activities) and behavioral changes in virtually any group or taxon of aquatic organisms may decrease the bioreactor efficiency. Some sublethal effects should be regarded as a potential hazard to the purification function (Ostroumov [1998], [2000a ], [2000b], [2002a]; Ostroumov et al. [1997], [1999 ] ). Because the main groups of macroorganisms and microorganisms play a substantial role in self-purification of ecosystems, it is very important to compare the sensitivities of the organisms to various contaminants. In some cases, macroorganisms are at least as sensitive (or even more sensitive) to contaminants as microorganisms (Table 2). According to the presently adopted regulation of ecological monitoring and bioassaying, the ability of chemical compounds to damage the self-purification potential of ecosystems is being tested using heterotrophic bacteria alone. However, it follows from Table 2 that this approach may result in an underestimation of the effects of contaminants on more sensitive biological components of self-purified ecosystems (e.g., some macroorganisms). We obtained new data on the ability of xenobiotics to inhibit water filtration by marine and freshwater organisms and on the hygienic function of pulmonary mollusks associated with elimination of organic matter (the removal of phytomass) from the water column in aquatic ecosystems (Table 3). Some sublethal concentrations of contaminants may inhibit vital activities of other organisms involved in the functioning of the ecosystem as an analog of a bioreactor (e.g., Ostroumov [2001], [2002a], Ostroumov et al. [1999]). 6. AQUATIC ECOSYSTEMS AS PART OF THE APPARATUS OF THE BIOSPHERE. V.I. Vernadsky considered the biota as the apparatus of the biosphere (Vernadsky, [2001]). To continue and develop his thought, we could consider aquatic ecosystems and aquatic biota as a key part of that apparatus. In that capacity, aquatic ecosystem carries a number of functions, not only the one function discussed above (water purification). Among those biospherically important functions are the following: (1) production of organic matter; (2) removing the excess organic matter; ( 3 ) mediating, catalyzing, and regulating biogeochemical flows and cycles; ( 4) harboring biodiversity and by doing so harboring the genetic pool of biodiversity; (5) providing links among various parts of the biosphere; ( 6) contributing to stability of the biosphere. 7. CONCLUSIONS. The fundamental concept put forward in this work emphasizes that both the biological diversity of aquatic organisms and their normal level of physiological activities are required to provide the effective functioning of an ecosystem as an analog of a bioreactor. That bioreactor carries a number of biospherically important functions and processes (we call them 'microbiospheric processes') including those of water purification (environmental remediation, ecological repair). This may lead to a deeper insight into the mechanisms of aquatic ecosystems and to better understanding of hazards of the anthropogenic impact on the biosphere (Yablokov, Ostroumov [1983], [1985], [1991]; Ostroumov [1986]; [Wetzel, 2001]).

For the first time, the quantitative assessment of the biogeochemical flows was made. Also, for the first time, it was discovered that a synthetic chemical may inhibit those flows. The pellet excretion by the gastropods Lymnaea stagnalis feeding on the phytomass of macrophytes (such as Nuphar lutea) was 4–7 mg dry weight per 1 gram wet weight of the mollusks per 72 h. Pellet sedimentation contributes to the vertical transfer of chemical elements in the ecosystem. The pellet composition depended on the species of the plants eaten by the mollusks. When the gastropods L. stagnalis feed on N. lutea, the pellets contain, in addition to organic and inorganic carbon, nitrogen (N, 2.3–2.9%), phosphorus (P, 0.4–0.5%), and silicium (silicon) (Si, 1.1–1.9%). The relative content of Si was 30% higher than in the food phytomass. The synthetic surfactant tetradecyltrimethylammonium bromide (TDTMA, 2 mg/L) inhibited the feeding rate of the mollusks and pellet production, their accumulation at the bottom of microcosms, and the matter transfer connected with this. The data obtained demonstrated a new aspect of the ecological hazard due to environmental pollution with TDTMA and other quaternary ammonium compounds at sublethal concentrations. According to the author’s opinion, other contaminants may also suppress pellet production, their accumulation at the bottom, and the matter transfer associated with that. http://scipeople.ru/users/2943391/; http://sites.google.com/site/2000dbs373p397biocatallstag/; INFORMATION ON CITATION: Cited, citation: Biocatalysis of Matter Transfer in a Microcosm Is Inhibited by a Contaminant: Effects of a Surfactant on Limnea stagnalis [Lymnaea stagnalis, great pond snail, Mollusca]; Ostroumov, S.

https://www.researchgate.net/publication/10669691; 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: (I) 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.
