Aquatic macrophytes Ceratophyllum demersum were incubated in some of the microcosms. The measured concentrations of all four metals decreased in the microcosms with macrophytes much faster than in the control microcosms without any macrophytes. The new data contribute to the scientific basis of innovative phytotechnology (phytoremediation) for treatment of polluted water and improving water quality.

Остроумов С. А. Новый тип действия потенциально опасных веществ: разобщители пелагиально-бентального сопряжения // Доклады академии наук (ДАН) т. 283, № 1. С.138-141. 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 filter-feeders, 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).

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;
