The role of biodetritus in accumulation of elements in aquatic ecosystems ; DOI: 10.1134/S1995425510040016;
https://www.researchgate.net/publication/225471572 ;Biodetritus that formed over a 7-month period in microcosms with Viviparus viviparus, Unio pictorum, and Ceratophyllum demersum contained a number of elements. This is the first study to determine concentrations of some elements in biodetritus. Neutron activation analysis showed that the elements’ concentrations decrease in the following order: Ca > Zn > Ba > Br > Ce > Se &...Journal: Contemporary Problems of Ecology - CONTEMP PROBL ECOL , vol. 3, no. 4, pp. 369-373, 2010; full text free: https://www.researchgate.net/publication/225471572 ;3
Biocontrol of water quality: Multifunctional role of biota in water self-purification DOI: 10.1134/S1070363210130086;
The experimental data analysis, concepts, and generalizations in this article provide the fundamental elements of the qualitative theory of biocontrol of water quality in a systematized form. The theory covers water self-purification in freshwater and marine ecosystems. The theory is supported by the results of the author’s experimental studies of the effects exerted by some chemical pollutants including synthetic ...Journal: Russian Journal of General Chemistry - RUSS J GEN CHEM , vol. 80, no. 13, pp. 2754-2761, 2010; full text free: https://www.researchgate.net/publication/227303635;
- A new contribution to the scientific basis of phytoremediation and phytotechnology for water treatment. It is the first paper that reports the experiment in which it was proved that the aquatic plants helped remove a synthetic surfactant from water. ** It was discovered that plant biomass help towards restoration the water quality in the system which was polluted with a synthetic ...Journal: Doklady Biological Sciences , vol. 425, no. 1, pp. 180-182, 2009; full text free: https://www.researchgate.net/publication/225149600 ;

In the presence of this aquatic, submerged, free-floating higher plant (rigid hornwort) in water system, it was discovered that a decrease in concentrations of the four heavy metals (cadmium; copper; lead; zinc; Cu, Zn, Cd, and Pb) in the water medium accelerated. The aquatic macrophytes served as a factor to speed up the water purification (decontamination) process in the aquatic system. The method for measuring the heavy metals was stripping voltammetry.

https://www.researchgate.net/publication/216175249; The goal of this study was to test whether the surfactant SDS has an inhibitory effect on the ability of the planktonic filter-feeder Daphnia magna to remove phytoplankton from water during their filtration activity. Daphnia were kept under laboratory conditions in vessels and fed with phytoplankton: the green algae Scenedesmus quadricauda (Turp.) Breb. After filtration for 6–24 h in the presence of SDS at concentrations 5 and 10 mg/l, the abundance of S. quadricauda cells in water was higher than in the control. At the lower SDS concentrations (0.1, 0.5, and 1 mg/l), differences in the abundance of algal cells relative to the control were observed after 3 h of incubation and disappeared after 6–24 h of incubation. The calculation of the mean rate of algae removal by daphnia showed that this parameter decreased within the first 3 h after the beginning of incubation in the presence of SDS.- A fragment of the text of the article: Many species of planktonic and benthic invertebrates are active filter-feeders. The filtration activity of aquatic organisms is of great importance for the functioning of ecosystems [1‐3]. It was shown earlier that surfactant sodium dodecylsulfate (SDS) inhibits the filtration activity of Mytilus edulis, M. galloprovincialis , and some other aquatic filter-feeders [4‐15], which is manifested in a decreased removal of ...

On the concepts of biochemical ecology and hydrobiology: Ecological chemomediators (Citations: 1+)
full text free: https://www.researchgate.net/publication/201999918;
DOI: 10.1134/S1995425508020100;Earlier, the author published two books and some papers, in which he described conceptual foundations of new scientific disciplines — biochemical ecology and biochemical hydrobiology. These trends in research include studies of the role of chemical substances in interorganismal interactions, in communication and regulation of supraorganismal systems. Another part of biochemical ecology concerns studies of the destiny and transformation of external ...- The paper formulates some basics of the modern ecological theory of the polyfunctional role of biota in the molecular-ecological mechanism of water quality formation and self-purification of aquatic ecosystems. The theory covers the following items: (1) sources of energy for self-purification mechanisms, (2) the main structural and functional units of the self-purification system, (3) the main ...Journal: Contemporary Problems of Ecology - CONTEMP PROBL ECOL , vol. 1, no. 1, pp. 147-152, 2008;

The effects of the anionic surfactant sodium dodecyl sulfate on the aquatic macrophyte Potamogeton crispus L. are studied. Concentrations of 83–133 mg/l caused fragmentation of the stems of plants. The tolerance of the plants to the negative effects of the surfactant was higher in the spring (April) than in the autumn (September).Journal: Moscow University Biological Sciences Bulletin , vol. 62, no. 4, pp. 176-179, 2007;

00032 Ispani mires - the sound of frogs on unidentified potamogeton natans PelophylaxPublished: 2011/07/12Channel: MarcelInGeorgie9- Effects of three surfactants on the filtration rates by marine mussels were studied. The xenobiotics tested represented anionic, cationic and non-ionic surfactants (tetradecyltrimethylammonium bromide, a representative of a class of cationic surfactants; sodium dodecyl sulphate, a representative of anionic alkyl sulfates; and Triton X-100, a representative of non-ionic hydroxyethylated alkyl phenols). All three surfactants inhibited the clearance ...
