Orlov Department of Biology, Moscow State University, Moscow, Russia email: ostroumov@mail.bio.msu.ru Received April 10, 2013 Abstract: Increased production and use of nanomaterials can lead to new types of pollution of the environment, including aquatic ecosystems. Pollution of the aqueous environment with nanoparticles can be a new type of pollution of the environment. This requires a more detailed study of the biological effects during exposure of nanoparticles on aquatic organisms. The interactions of gold nanoparticles (Au) with aquatic macrophytes Ceratophyllum demersum have been studied. Aquatic microcosms with these plants were used. Gold nanoparticles (Au) were added to the aqueous medium of C. demersum macrophyte containing microcosms. The state of the plants was then analyzed. Phytotoxicity of Au nanoparticles for aquatic macrophytes was shown for the first time. A new method of phytotoxicity detection was suggested and successfully approved. Phytotoxicity at a concentration of Au (in the form of nanoparticles) of 6 . 10–6 M–1.8 . 10–5 M was shown. Original Russian Text © S.A. Ostroumov, V.A. Poklonov, S.V. Kotelevtsev, S.N.

Russian Journal of Ecology, Vol. 36, No. 6, 2005, pp. 414–420. Translated from Ekologiya, No. 6, 2005, pp. 452–459; ABSTRACT: Principles of the theory of the ecological mechanism of water self-purification based on multiple functions of the biota in freshwater and marine ecosystems are formulated. In developing this theory, the results of the author’s experiments with filtering hydrobionts have been used. These results indicate that the water selfpurification mechanism is vulnerable to the impact of some pollutants and, in particular, surfactants. Conclusions drawn on the basis of the theory have practical significance for biodiversity conservation and for the sustainable use of the biological resources of aquatic ecosystems. The first paper to formulate in detail the new qualitative theory of multifunctional activity of organisms in improving water quality, in other words, the theory of water self-purification by organisms. http://5bio5.blogspot.com/2014/03/article-on-multifunctional-role-of.html ; http://www.researchgate.net/publication/227317445_On_the_Multifunctional_Role_of_the_Biota_in_the_Self-Purification_of_Aquatic_Ecosystems; link.springer.com/article/10.1007%2Fs11184-005-0095-x‎; Additional data in support of the conclusions of this paper: see the book: Biological Effects of Surfactants.

The innovative experimental data analysis, concepts, and generalizations in this article provide the fundamental elements of the new 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 surfactants, detergents, and other xenobiotics on aquatic organisms. The new fundamental conceptualization provides a basis for remediation of polluted aquatic ecosystems including purification of water bodies and streams, and briefly present the qualitative theory of the self-purification mechanism of aquatic ecosystems, phytoremediation and other types of technologies.

Effect of environmental pollution with a cationic surface-active substance on algae and Fagopyrum esculentum sprouts. – The Soviet Journal of Ecology [ISSN 00967807; later the journal was entitled: Russian Journal of Ecology]. 1990. Vol. 21. No.2, p. 79-81. http://scipeople.com/publication/70248/ 3 tables. Bibliogr. 10 refs. [in collaboration: Ostroumov S.A., Tret’yakova A.N. ). [At that moment of time the journal was published by Plenum Publishing Corporation, 233 Spring St., N.Y., N.Y. 10013; the reference number of the publication published at the first page of the paper: 0096-7807/90/2102-0079]. The effects of environmental pollution with a cationic surface-active substance (surfactant tetradecyltrimethylammonium bromide TDTMA) on certain cyanobacteria and algae - cyanobacteria Nostoc muscorum Ag, strain 33 isolated from the soil in the Kirov Oblast (Region); green algae Bracteacoccus minor (Chodat) Petrova, strain 200 and strain 219 (the strain 219 was isolated from the volcanic ash collected next to Tyatya Volcano, island of Kunashir) - was investigated. Their sensitivity to that surfactant TDTMA was compared with the sensitivity of a test based on the use of terrestrial plants. The algal experiments were performed with aquatic and soil cultures. The experiments with terrestrial plants used the earlier-developed method with seedlings of Fagopyrum esculentum Moench. TDTMA at concentrations 1 mg/L and above produced some negative effects on cyanobacteria and algae in aquatic cultures. TDTMA at concentrations 50 mg/L and above produced some negative effects on cyanobacteria and algae (diatoms) in soil cultures. TDTMA at a concentration 100 mg/L produced some negative effects on all organisms tested in the soil cultures. TDTMA at a concentration 100 mg/L decreased the number of cells per 1 g of soil; the decrease was observed for cyanobacteria, green algae, and diatoms. The experiments revealed the higher sensitivity of the test with the aquatic algal cultures.

Although acetylenes are common as components of terrestrial plants, it is only within the last 30 years that biologically active polyacetylenes having unusual structural features have been reported from aquatic organisms: cyanobacteria, algae, fungi, invertebrates, and other sources. Naturally occurring aquatic acetylenes are of particular interest since many of them display important biological activities and possess antitumor, antibacterial, antimicrobial, antifouling, antifungal, pesticidal, phototoxic, HIV inhibitory, and immuno-suppressive properties. There is no doubt that they are of great interest, especially for the medicinal and/or pharmaceutical industries. This review presents structures and describes cytotoxic and anticancer activities of more than 230 acetylenic metabolites isolated from aquatic organisms. With the computer program PASS some additional biological activities are also predicted, which point toward possible new applications of these compounds. This review emphasizes the role of aquatic acetylenic compounds as an important source of leads for drug discovery.
