Journal ArticleDOI
Toxicity of Ag, CuO and ZnO nanoparticles to selected environmentally relevant test organisms and mammalian cells in vitro: a critical review
Olesja Bondarenko,Katre Juganson,Katre Juganson,Angela Ivask,Kaja Kasemets,Monika Mortimer,Monika Mortimer,Anne Kahru +7 more
TL;DR: The toxic range of all the three metal-containing NPs to target- and non-target organisms overlaps, indicating that the leaching of biocidal NPs from consumer products should be addressed.
Journal ArticleDOI
Mechanisms of toxic action of Ag, ZnO and CuO nanoparticles to selected ecotoxicological test organisms and mammalian cells in vitro: A comparative review
Angela Ivask,Katre Juganson,Olesja Bondarenko,Monika Mortimer,Villem Aruoja,Kaja Kasemets,Irina Blinova,Margit Heinlaan,Vera I. Slaveykova,Anne Kahru +9 more
TL;DR: This review provides a comprehensive and critical literature overview on Ag, ZnO and CuO NPs’ toxicity mechanisms on the basis of various environmentally relevant test species and mammalian cells in vitro and three major phenomena driving the toxicity of these nanoparticles are revealed.
Journal ArticleDOI
Photocatalytic antibacterial activity of nano-TiO2 (anatase)-based thin films: effects on Escherichia coli cells and fatty acids.
Urmas Joost,Katre Juganson,Meeri Visnapuu,Monika Mortimer,Anne Kahru,Ergo Nõmmiste,U. Joost,Vambola Kisand,Angela Ivask +8 more
TL;DR: It is suggested that peroxidation and decomposition of membrane fatty acids could be one of the factors contributing to the morphological changes of bacteria observed under SEM, and ultimately, cell death.
Journal ArticleDOI
NanoE-Tox: New and in-depth database concerning ecotoxicity of nanomaterials
TL;DR: A database based on existing literature on ecotoxicology of eight ENMs with different chemical composition that contains valuable information for ENM environmental hazard estimation and development of models for predicting toxic potential of ENMs.
Journal ArticleDOI
Toxicity of nine (doped) rare earth metal oxides and respective individual metals to aquatic microorganisms Vibrio fischeri and Tetrahymena thermophila
Imbi Kurvet,Katre Juganson,Katre Juganson,Heiki Vija,Mariliis Sihtmäe,Irina Blinova,Guttorm Syvertsen-Wiig,Anne Kahru,Anne Kahru +8 more
TL;DR: According to kinetics of V. fischeri bioluminescence, the toxicity of REEs was triggered by disturbing cellular membrane integrity, and as REEs and REOs are currently produced in moderate amounts and form in the environment insoluble salts and/or oxides, they apparently present no harm to aquatic bacteria and protozoa.
