TLDR
It is concluded that nanometals do have adverse physiological effects on fish, and the hazard for some metal NPs will be different to the traditional dissolved forms of metals.About:

Journal ArticleDOI
An assessment of applicability of existing approaches to predicting the bioaccumulation of conventional substances in nanomaterials
TL;DR: The use of kinetic models, including physiologically based pharmacokinetic models, appears to be the most suitable approach for predicting bioaccumulation of NMs.
Journal ArticleDOI
Silver nanoparticles stimulate glycogenolysis in rainbow trout (Oncorhynchus mykiss) hepatocytes
TL;DR: It is suggested that AgNPs could affect hormone-regulated cell signaling pathways at a concentration of 10 μg/mL, rather than the current concentration of 1 μg/ mL, which is commonly used in clinical practice.
Journal ArticleDOI
Copper oxide nanoparticles induce oxidative stress mediated apoptosis in carp (Cyprinus carpio) larva
TL;DR: In this article, the effects of copper oxide nanoparticles on tissue histology, bioaccumulation, antioxidant enzymes activity and expression of apoptosis genes of the carp (Cyprinus carpio) larvae were investigated.
Journal ArticleDOI
Intensive epidermal adsorption and specific venous deposition of carboxyl quantum dots in zebrafish early-life stages
TL;DR: It is found that the exact tissue condition including epidermal structures, mucus secretion and vascular microstructures strongly affected the adsorption, uptake and distribution of carboxyl-QDs in zebrafish.
Journal ArticleDOI

TL;DR: The results demonstrated the enhanced toxicological responses in fish after 21 days of dietary exposure, but the levels of most of biochemical indices and tissues Cu content decreased or returned to the control values after the recovery period.

Nanomaterials in the environment: Behavior, fate, bioavailability, and effects
Stephen J. Klaine,Pedro J. J. Alvarez,Graeme E. Batley,Teresa F. Fernandes,Richard D. Handy,Delina Y. Lyon,Shaily Mahendra,Mike J. McLaughlin,Jamie R. Lead +8 more
TL;DR: This review critiques existing nanomaterial research in freshwater, marine, and soil environments and illustrates the paucity of existing research and demonstrates the need for additional research.
Journal ArticleDOI
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.
Book
Cadmium in the environment
TL;DR: In this paper, a review on cadmium in the environment has been performed under a contract between the U.S. Environmental Protection Agency and the Department of Environmental Hygiene of the Karolinska Institute, Sweden.
Journal ArticleDOI
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.
