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.

Ostroumov S.A., Kolesov G.M. The aquatic macrophyte Ceratophyllum demersum immobilizes Au nanoparticles after their addition to water. Dokl Biol Sci. 2010 (Mar-Apr); 431: 124-127. Affiliation: Faculty of Biology, M.V. Lomonosov Moscow State University, Moscow 119991, and Institute of Geochemistry, Moscow, Russia. It was discovered that the aquatic plant (macrophyte) Ceratophyllum demersum immobilized gold (Au) nanoparticles after their addition to water. It is the first time it was shown. The method that was used to detect and measure the conctntrations of gold in the biomass of plants (phytomass) was NAA (neutron activation analysis). http://www.ncbi.nlm.nih.gov/pubmed/20506851; PMID: 20506851 [PubMed] Key words: nanotechnology, nanoparticles, Au, gold, biogeochemistry, biotechnology, aquatic plants, macrophyte, Ceratophyllum demersum, Immobilization, water quality, monitoring, environmental science, ecology
