Influence of calcium and EDTA on copper ion bioavailability in copper nanoparticle toxicity tests improves understanding of nano-specific effects:
Halis Boran,Halis Boran +1 more
TL;DR: EDTA and calcium significantly decreased Cu toxicity in freshwater fish, and the differences in concentration relationships of MT2 expression between Cu-NPs and CuSO4 indicated that factors other than release of Cu ions from Cu-nPs influenced acute toxicity of Cu- NPs.

TL;DR: The classical ZnNPs and AgNPs exhibited excellent inhibition potential and significant transfiguration of hematological, enzymological, and protein parameters as safe nanomedicine, but ZnONPs were found to be 58, 69, 29 and 34, 51, 70% more active than AgNps with 4-day and 15-day treatment, respectively.

Ecotoxicological effects of silver nanoparticles in marine mussels
TL;DR: In this paper, the area under the curve (AUC) was used as an independent variable in hazard assessment to predict toxicity and bioaccumulation of 5 nm alkane-coated and 50 nm uncoated silver nanoparticles.

Comparative Toxicity of Alpha and Gamma Iron Oxide Nanoparticles in Rainbow Trout: Histopathology, Hematology, Accumulation, and Oxidative Stress
TL;DR: In this article, alpha and gamma iron oxide nanoparticles, characterizations, toxic effects after being exposed to rainbow trout (Oncorhynchus mykiss) at 0, 1, 10 and 25 mg/L concentrations for 10 days, and then 10-day recovery period without any nanoparticle exposure were examined for histopathological (kidney, liver and gill), hematological, iron accumulation and potential for oxidative stress (TBARS and GSH).

Modeled Environmental Concentrations of Engineered Nanomaterials (TiO2, ZnO, Ag, CNT, Fullerenes) for Different Regions
TL;DR: The results of this study indicate that risks to aquatic organisms may currently emanate from nano- Ag, nano-TiO(2), and nano-ZnO in sewage treatment effluents for all considered regions and for nano-Ag in surface waters.

Manufactured nanomaterials (fullerenes, C60) induce oxidative stress in the brain of juvenile largemouth bass.
TL;DR: This is the first study showing that uncoated fullerenes can cause oxidative damage and depletion of GSH in vivo in an aquatic species, and further research needs to be done to evaluate the potential toxicity of manufactured nanomaterials, especially with respect to translocation into the brain.

TL;DR: In this paper, the Free-Ion Activity Model (FIAM) was used to model the relationship between trace metals and aquatic organisms, and the results showed that metal toxicity in aquatic organisms can be predicted from bioassays.
