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.

Tolerance of an aquatic macrophyte Potamogeton crispus L. to sodium dodecyl sulphate. - Moscow University Biological Sciences Bulletin, 2007. 62(4):176-179. (in English); Abstract: The effects of the anionic surfactant sodium dodecyl suplphate on the aquatic macrophyte Potamogeton crispus L. were 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). DOI:10.3103/S0096392507040074. Allerton Press, Inc.

Разработанный метод и полученные количественные данные вносят вклад в изучение фитотоксичности СМС и фиторемедиационного потенциала этого вида водных растений. Abstract: The additions of the detergent Aist to microcosms with Fontinalis antipyretica Hedw. were used for studies of the phytotoxicity and phytoremediation potential of the aquatic macrophytes. The effects of the detergent on the aquatic macrophytes Fontinalis antipyretica Hedw. were studied.

Микрокосмы с макрофитами изучали в лабораторных экспериментах. исследовали воздействие додецилсульфата натрия (ДСН) на макрофиты. Регистрировали выживаемость и вес биомассы макрофитов в условиях длительной инкубации. ДСН вносили в форме неоднократных (повторяющихся, рекуррентных) добавок. Количество ДСН, внесенное в 1 дм3 после каждой добавки составляло: 0,5, 0,8, 1,7, 8,3, 16,7, 50,0 и 100,0 мг. Длительность периода выживания растений снижалась при увеличении количества ДСН, вносимого в одной добавке. Если количество вносимого ДСН (в одной добавке) увеличивали в 200 раз (с 0,5 до 100 мг/л), то период выживания снизился в 53 раза (с 372 до 7 дней). В присутствии ДСН произошло некоторое снижение биомассы макрофитов. Степень снижения биомассы зависела от суммарного количества внесенного ДСН. Solomonova E.A., Ostroumov S.A. Effects of sodium dodecyl sulphate on the biomass of macrophytes Najas guadelupensis L. / / Toksikologicheskiy Vestnik. 2009. Number 2. P.32-35. Bibliogr.10 refs. Microcosms with the macrophytes were studied in laboratory experiments. The effects of sodium dodecyl sulphate (SDS) on macrophytes were studied . The survival and weight of the biomass of macrophytes in a prolonged incubation were recorded. SDS was added in the form of repeated (recurrent) additives. The increase in the amount of SDS after each addition was: 0,5, 0,8, 1,7, 8,3, 16,7, 50,0 and 100,0 mg in 1 dm3. Duration of survival of plants decreased with increasing amount of SDS in one addition. If the amount of SDS (after a single addition) increased 200 times (from 0.5 to 100 mg / l), the period of survival decreased 53-fold (from 372 up to 7 days). In the presence of SDS, a decrease in macrophyte biomass was observed. The degree of the reduction of biomass depended on the total amount of SDS added to the microcosms.
