Abstract/OtherAbstract:
The preparation of aqueous suspensions of carbon-based nanomaterial (NMs) requires the use of dispersing agents to overcome their hydrophobic character. While studies on the toxicity of NMs have focused primarily on linking particles' characteristics to biological responses, the role of dispersing agents has been overlooked. This study assessed the biological effects of a number of commonly used dispersing agents on Pseudokirchneriella subcapitata and Ceriodaphnia dubia as model test organisms. The results show that: for a given organism, NM toxicity can be mitigated by use of non-toxic surfactant, and that a multi-species approach is necessary to account for the sensitivity of different organisms. In addition to NM intrinsic physicochemical properties, exposure studies should take into account the effects of used dispersing fluids. Environ. Toxicol. Chem. © 2011 SETAC.
