Экологическая биогеохимия и элементы ( As, Со, Fe, Mn, Zn, Cu, Cd, Cr) в цистозире и биогенном детрите в морской модельной экосистеме: определение методом атомно-абсорбционной спектрометрии (ААС) // Экологические системы и приборы. 2009. №9, с. 42-45.[Авторы:Остроумов С.А., Демина Л.Л.] Детрит, образовавшийся за время более 10 месяцев в микрокосмах с Mytilus galloprovincialis, содержал ряд металлов и мышьяк. Впервые измерены концентрации таком детрите 9 элементов. Их концентрация была измерена с помощью атомной абсорбционной спектроскопии (ААС). Концентрации уменьшались в следующем порядке: Fe > Mn > Zn > Cu > As > Cr > Pb > Co > Cd. Кроме того, были измерены концентрации тех же элементов в бурых водорослях Cystoseira crinita из Черного моря. Концентрации уменьшались в следующем порядке: Fe> Zn> Mn> Cr> As> Cu> Pb> Cd> Co. Данные подтверждают предложенную теорию полифункциональной роли биоты в контроле качества воды и ее самоочищении (ДАН, 2004, Т.396. С.136-141; Экология, No. 6, 2005, с. 452–459). --ABSTRACT: Ostroumov S.A., Demina L.L. Ecological biogeochemistry and chemical elements (As, Со, Fe, Mn, Zn, Cu, Cd, Cr) in biogenic detritus in marine model ecosystem: measuring by the method of atomic absorption spectroscopy (AAS) // Ecological Systems and Devices (= Ekologicheskie sistemy i pribory). 2009. No. 9, p. 42-45. The detritus that accumulated over > 10 months in the microcosms with Mytilus galloprovincialis contained As and metals. For the first time the concentrations of 9 elements in the detritus of this type was measured. Their concentrations were measured using atomic absorption spectroscopy (AAS). Their concentrations decreased in the order: Fe > Mn > Zn > Cu > As > Cr > Pb > Co > Cd. Also, concentrations of the same elements in Cystoseira crinita were measured. The concentrations decreased in the order: Fe > Zn > Mn > Cr > As > Cu > Pb > Cd > Co. The new data confirm the recent theory of the polyfunctional role of the biota in water quality control and water self-purification (Doklady Akademii Nauk, 2004, V.396. P.136-141; Ekologiya, No. 6, 2005, p. 452–459). --КЛЮЧЕВЫЕ СЛОВА: Биогенный детрит, микрокосмы , биота , качество воды, самоочищение воды, моллюски, мидии, морские макрофиты, тяжелые металлы, As, Со, Fe, Mn, Zn, Cu, Cd, Cr, Cystoseira crinita, Mytilus galloprovincialis, атомно-абсорбционная спектрометрия (ААС); поллютанты, загрязнение, загрязнители, экологическая безопасность, экотоксикология, водная токсикология, биогеохимия, биогенная миграция элементов, микрокосмы, Черное море, мониторинг, донные осадки, эссенциальные элементы, не-эссенциальные, аккумуляция и иммобилизация элементов, сестон, пеллеты, Lymnaea stagnalis, Unio tumidus, U. pictorum, Crassiana crassa, Anodonta, функции биоты, полезные функции экосистем; --KEY WORDS: biogenic detritus, microcosms, the biota, water quality, water self-purification, mollusks, marine macrophytes, heavy metals, As, Со, Fe, Mn, Zn, Cu, Cd, Cr, Cystoseira crinita, Mytilus galloprovincialis, atomic absorption spectroscopy (AAS); pollutants, pollution, contaminants, environmental safety, ecotoxicology, aquatic toxicology, biogeochemistry, biogenic migration of elements, microcosms, the Black Sea, monitoring, bottom sediments, essential elements, non-essential, accumulation, uptake, immobilization of elements, seston, pellets, Lymnaea stagnalis, Unio tumidus, U. pictorum, Crassiana crassa, Anodonta, functions of the biota, ecosystem’s services;

Effects of synthetic surfactants on hydrobiological mechanisms of self-purification of aquatic environment // Water Resources (Vodnye Resursy = Водные ресурсы), 2004. V. 31. No. 5. P. 546-555. Long-term studies of the biological effect of surfactants, including the effect surfactants exert on filter feeders, are reviewed. The role of filter feeders in the functioning of freshwater and marine ecosystems is analyzed. New aspects in the assessment of environmental hazard due to the impact of chemical pollutants, including surfactants and detergents, are established. ---KEY WORDS: water quality, effect of synthetic surfactants, hydrobiological mechanisms, water self-purification, water resources, biological effect of surfactants, effect on filter feeders, role of filter feeders, suspension feeders, functioning of freshwater and marine ecosystems, new aspects, assessment of environmental hazard, impact of chemical pollutants, detergents, tensides, bivalves, mollusks, bioassays, biotesting, pollutants, xenobiotics, contaminants, inhibition, sublethal effects, environmental safety, pollution control. ---КЛЮЧЕВЫЕ СЛОВА: качество воды, влияние синтетических поверхностно-активных веществ, ПАВ, гидробиологические механизмы самоочищения воды, водные ресурсы, биологическое действие поверхностно-активных веществ, фильтраторы, роль фильтраторов, ингибирование питания, функционирование пресноводных и морских экосистем, новые аспекты, оценка экологической опасности, воздействие химических загрязняющих веществ, детергенты, моющие средства, поверхностно-активные вещества, двустворчатые моллюски, биотесты, биотестирование, загрязняющие вещества, ксенобиотики, поллютанты, сублетальные концентрации и воздействия, экологическая безопасность, борьба с загрязнением. http://sites.google.com/site/ostroumovsergei/publications-1/the-effect-of-synthetic-surfactants-on-the-hydrobiological-mechanisms-of-water-self-purification; ---http://3358416240217566007-a-1802744773732722657-s-sites.googlegroups.com/site/ostroumovsergei/publications-1/the-effect-of-synthetic-surfactants-on-the-hydrobiological-mechanisms-of-water-self-purification/WR502.pdf?attachauth=ANoY7crIRymw1V221NC0zANRTtmnFKiKwb6TDGYJt9HhTMp1EbueGpkNF1x1AOqWI0fkI0z7smbAom63xxns5XakKw6DqN61lpTDQmZwgfXunBE411oS8-bH71YSO5TRdq1Su7dLukbutIK5xE3bZU6c29Z2rBbb887JrRXjVhmlqQ0JK-Kr_3T3cm1mR15Pudm9NU9KMYu1uxCsPXQG-9Qz3UiGBWYDEOdNJl8DsR5h8lBvhQSg1XQzKI7KMcA1nnDfxv3KkqlgXUnxpurQMJih2-CyoYC7BvtJ9tkLo3Iqh3_jRlq1zBDT7H3TYzRBOuK4cv4qMxwThBscArXn0ZCMdpDt1IHk0S1WRV7H6hsCBgidn-weErM%3D&attredirects=0

Biocatalysis of matter transfer in a microcosm is inhibited by a contaminant: effects of a surfactant on Lymnaea stagnalis. - Doklady Biological Sciences, Vol. 373, 2000, pp. 397–399. [Translated from Doklady Akademii Nauk, Vol. 373, No. 2, 2000, pp. 278–280]. --Pellet excretion by the gastropods Lymnaea stagnalis feeding on the phytomass of macrophytes (such as Nuphar lutea) was as high as 4–7 mg absolute dry weight per gram wet weight of mollusks per 72 h. Pellet sedimentation contribute to vertical transfer of chemical elements in the ecosystem. The pellet composition varies depending on the species of the plants eaten by the mollusks. When 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 (Si, 1.1–1.9%). The relative silicium content may be 30% higher than in the food phytomass. The surfactant tetradecyltrimethylammonium bromide (TDTMA, 2 mg/L) inhibited 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 opinion, other contaminants may also suppress pellet production, their accumulation at the bottom, and the matter transfer associated with that. --KEY WORDS: gastropods, Lymnaea stagnalis, Radix ovata, Physa fontinalis, Nuphar lutea, Taraxacum officinale, tetradecyltrimethylammonium bromide, TDTMA, mollusks, pellet sedimentation, vertical transfer, chemical elements, aquatic ecosystem, nitrogen, phosphorus, silicium, Si, ecological hazard, environmental pollution, quaternary ammonium compounds, sublethal concentrations, contaminants, matter transfer, xenobiotics, toxicity, bioassay, microcosm, detritus, feeding rate, invertebrates, water self-purification;
