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.

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.
