“…Some NMs are photoactive and can be responsible for production of reactive oxygen species; their nanosize favors their ability to cross cell membranes and to interact with cellular components (Li et al 2002;Colvin 2003). Although there are some emerging literatures addressing the biological effects of NMs to aquatic organisms, most of the information available are contradictory and vague (Farré et al 2009;Krysanov et al 2010). The most studied metal oxide is the nano-TiO 2 focusing on acute toxicity and mainly testing NPs around 100 nm (Nogueira et al 2012;Miller et al 2012;Song et al 2012;Ates et al 2013).…”

The rapid development of nanotechnology and the increasing use of nanomaterials (NMs) raise concern about their fate and potential effects in the environment, especially for those that could be used for remediation purposes and that will be intentionally released to the environment. Despite the remarkable emerging literature addressing the biological effects of NMs to aquatic organisms, the existing information is still scarce and contradictory. Therefore, aimed at selecting NMs for the treatment of organic and inorganic effluents, we assessed the potential toxicity of NiO (100 and 10-20 nm), Fe2O3 (≈85 × 425 nm), and TiO2 (<25 nm), to a battery of aquatic organisms: Vibrio fischeri, Raphidocelis subcapitata, Lemna minor, Daphnia magna, Brachionus plicatilis, and Artemia salina. Also a mutagenic test was performed with two Salmonella typhimurium strains. Suspensions of each NM, prepared with the different test media, were characterized by dynamic light scattering (DLS) and eletrophoretic light scattering (ELS). For the assays with marine species, no toxicity was observed for all the compounds. In opposite, statistically significant effects were produced on all freshwater species, being D. magna the most sensitive organism. Based on the results of this study, the tested NMs can be classified in a decreasing order of toxicity NiO (100 nm) > NiO (10-20 nm) > TiO2 (<25 nm) > Fe2O3, allowing to infer that apparently Fe2O3 NMs seems to be the one with less risks for receiving aquatic systems.

“…Biotransformation can have a major influence on the chemical structure of environmental contaminants, including ENPs, thus influencing how the constituents are transported, where they accumulate, for example in water, soil or biota, and whether they are bioavailable and toxic [2,9]. For example, the desert plants Parkinsonia florida, Prosopis juliflora-velutina, and Salsola tragus take up and biotransform ZnO ENPs, storing most of the material as Zn 2+ in their roots and leaves [10,11], while Glycine max plants (soybean) accumulate CeO 2 and biotransform ZnO ENPs [12].…”

ZnS nanoparticles of different sizes are synthesized employing a simple wet chemical method. These nanoparticles are used to study their impact on the Daphnia sp. through traditional toxicity tests. The percentage of mortality is found to increase initially with increasing nanoparticle concentration or exposure time and is finally found to saturate for higher concentrations or exposure times. Mortality is found to be higher for smaller particles. Hopping frequency and heart rate are also found to increase with increasing nanoparticle exposure time for a fixed nanoparticle concentration. These observations can be attributed to the enhanced surface photooxidation property of the ZnS nanoparticles. Thus the present study will help people to understand the hitherto unknown harmful impact of ZnS nanoparticles on aquatic organisms in the western part of West Bengal (Bankura and Purulia districts), India.
