TL;DR: The findings contribute to elucidation of the factors involved in the toxicity of these nanoparticles, as well as to the establishment of protocols for risk assessments of nanotechnology.

TL;DR: This study used Pseudokirchneriella subcapitata, Artemia salina and Daphnia similis as model organisms to investigate the toxicity of PVA-stabilized AgNP at several concentration levels and found a higher toxicity than other results reported for other daphnids.

TL;DR: A review of the principal properties of TiO2, especially in nanoparticulate form, which should be considered in aquatic toxicology studies, and a compilation of the works that have been published on the subject can be found in this paper.

TL;DR: The ecotoxicity and genotoxicity assays showed that humic substances can decrease the toxic effects of nanoparticles containing paraquat, and are important for understanding the interaction of these nanostructured carrier systems with species present in aquatic ecosystems.

TL;DR: Evaluating the effects on fish exposed to different nano-TiO2 concentrations and illumination conditions provided information for the development of protocols to study substances whose toxicity is affected by illumination conditions and demonstrated the importance of considering the experimental conditions in nanoecotoxicological tests.
