Ostroumov S.A., Kotelevtsev S.V. Toxicology of nanomaterials and environment. - Ecologica. 2011, vol. 18, issue 61, pp. 3-10. Manufactured nanoparticles demonstrated a variety of biological activities, including toxicity. The goal of this review articles is to summarize some evidence of a variety of toxic effects produced by manufactured nanoparticles, including both the data from literature and the new data of the authors (e.g., [42]). The toxicity of nanomaterials was shown both to prokaryotic and eukaryotic organisms. As for eukaryotic organisms, toxicity was found in bioassays with both animal and plant test systems. In further studies, it is necessary to continue the studies of various aspects of toxicity of nanoparticles, and to extend the range of organisms and test systems that are being used for assessing the biological effects of nanomaterials. The methods that were previously developed to study phytotoxicity of chemicals [15-28, 48] will be useful to generate new data on toxicology of nanomaterials.

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.
