Journal ArticleDOI
Correlation of α/γ-Fe2O3 nanoparticles with the toxicity of particulate matter originating from subway tunnels in Seoul stations, Korea.
Le Thi Nhu Ngoc,Yong Il Lee,Hang-Suk Chun,Ju-Young Moon,Jin Seok Choi,Duckshin Park,Young-Chul Lee +6 more
TL;DR: It is considered that α-Fe2O3 NPs were primarily responsible for the harmful effects of PM, resulting in significant damage to DNA due to their capacity of producing high reactive oxygen species (ROS) and, thus, deleterious effects on the human body.

TL;DR: In vitro incubations of cell-free rat blood plasma with nZnO failed to generate any significant increase in malondialdehyde or protein carbonyl levels, or any significant decrease in ferric reducing ability of plasma, which suggests that at the level tested, any oxidative stress caused by nZNO is the result of a coordinated physiological response by the liver.

Antibiotic resistance in aquaculture and aquatic organisms: a review of current nanotechnology applications for sustainable management
Emmanuel Okeke,K. I. Chukwudozie,Raphael Nyaruaba,Richardson Ita,Abiodun Oladipo,Onome Ejeromedoghene,E Atakpa,Chidozie Victor Agu,Charles Obinwanne Okoye +8 more
TL;DR: In this article , a review of ecofriendly nanotechnological methods including nanodrug and vaccine delivery, nanoformulations, and nanosensor for their antimicrobial effects in aquaculture and aquatic organisms, potential public health risks associated with nanoparticles, and their mitigation measures for sustainable management.

Effects of subchronic exposure to zinc nanoparticles on tissue accumulation, serum biochemistry, and histopathological changes in tilapia (Oreochromis niloticus).
Hasan Kaya,Muge Duysak,Mehmet Akbulut,Sevdan Yilmaz,Mert Gürkan,Zikri Arslan,Veysel Demir,Mehmet Ates +7 more
TL;DR: Exposure to ZnNPs could lead to disturbances in blood biochemistry and cause histopathological injuries in the tissues of O. niloticus and Environ Toxicol 32: 1213–1225, 2017.
Journal ArticleDOI
Effect of nanosilver on cortisol release and morphometrics in rainbow trout (Oncorhynchus mykiss).
TL;DR: The results indicate that although nAg did engage the stress response in fish, it did not affect growth or condition under the experimental conditions and time frame investigated.

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.

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.

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.

Metal speciation and bioavailability in aquatic systems
André Tessier,David R. Turner +1 more
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.
