Health status of male steel workers at an electric arc furnace (EAF) in Trentino, Italy
TL;DR: A statistically significant increase of diabetes, cardiovascular diseases and deaths due to lung cancer in exposed workers is found and cannot be explained by PAH exposure alone; metal particulates are the most important pollutants in the working area of EAFs.

Proposal for a tiered dietary bioaccumulation testing strategy for engineered nanomaterials using fish
Richard D. Handy,Jukka Ahtiainen,José María Navas,Greg G. Goss,Eric A. J. Bleeker,Frank von der Kammer +5 more
TL;DR: In this paper, a tiered approach for bioaccumulation testing of engineered nanomaterials using fish is proposed, with recommendations for its implementation by regulatory agencies, which recognises that testing the many shapes, sizes and chemistries of ENMs as new substances in vivo would be an unrealistic workload.

Dynamics of metal uptake by charged biointerphases: bioavailability and bulk depletion
TL;DR: The mathematical framework is applied to practical situations where a swarm of charged microorganisms deplete metals under steady-state transport conditions and illustrates how metal transport dynamics impacts biouptake depending on electrolyte concentration and on the key bio-physico-chemical properties of the biointerphase.

Iron oxide nanoparticles induced alterations in haematological, biochemical and ionoregulatory responses of an Indian major carp Labeo rohita
Manoharan Saravanan,R. Suganya,Mathan Ramesh,Rama Krishnan Poopal,Natarajan Gopalan,N. Ponpandian +5 more
TL;DR: It was found that the Fe2O3 NPs do have prominent effects on freshwater fish L. rohita and the alterations of these parameters can be used as nonspecific biomarkers to monitor the environmental risks arising from nanoparticles in aquatic ecosystem and also regulate the use, production and release of nanoparticles.
Journal ArticleDOI
Preparation, activity and structure of cross-linked enzyme aggregates (CLEAs) with nanoparticle.
TL;DR: This study showed that it was potential to improve CLEAs performance by nano-TiO2 addition, and FT-IR results showed that NPs addition increases the content of regular structure of CLEAs, and causes a partial transformation of β-turn into β-sheet.

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.

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.
