Proposal for a tiered dietary bioaccumulation testing strategy for engineered nanomaterials using fish
The scientific community has invested effort into standardising methodologies for the regulatory ecotoxicity testing of engineered nanomaterials (ENMs), but the practical requirements for bioaccumulation testing of ENMs have been given less attention.
Dissolution as a paradigm in regulating nanomaterials
Dissolution is a factor to consider when interpreting human health and ecotoxicological studies.
Lifetime eco-nanotoxicology in an adult organism: where and when is the invertebrate C. elegans vulnerable?
This review addresses nanotoxicology in the nematode roundworm Caenorhabditis elegans throughout its entire life span, premature functional aging of the target organs and ecological considerations.
Aging reduces the toxicity of pristine but not sulphidised silver nanoparticles to soil bacteria
Aging of silver nanoparticles shows soluble silver driving toxicity in ISO medium, but not in media containing natural organic matter.
On the application of spectral corrections to particle flux measurements
An altered empirical method to estimate attenuation correction factors in particle flux measurements.
Expert perspectives on potential environmental risks from nanomedicines and adequacy of the current guideline on environmental risk assessment
Interviews conducted with 66 experts to gather their perspectives on environmental risks from nanomedicines and their responses analysed using qualitative content analysis.
Uptake and impacts of polyvinylpyrrolidone (PVP) capped metal oxide nanoparticles on Daphnia magna: role of core composition and acquired corona
A key hypothesis in nanosafety assessment is that the NP core chemistry and eco-corona are primary factors controlling toxicity.
Graphene oxide impairs the pollen performance of Nicotiana tabacum and Corylus avellana suggesting potential negative effects on the sexual reproduction of seed plants
The acidic properties of GO impair pollen performances of tobacco and hazel plants.
Reactive oxygen species generation is likely a driver of copper based nanomaterial toxicity
Determining the specific nanomaterial features that elicit adverse biological responses is important to inform risk assessments, develop targeted applications, and rationally design future nanomaterials.
Different effects of nano-scale and micro-scale zero-valent iron particles on planktonic microorganisms from natural reservoir water
This study compares the effect of nanoscale and microscale zerovalent iron on natural freshwater microplankton over 21 days.
Ageing, dissolution and biogenic formation of nanoparticles: how do these factors affect the uptake kinetics of silver nanoparticles in earthworms?
Discrimination between nano (≥20 nm) and ionic Ag in earthworms exposed to Ag-NPs, Ag2S-NPs and AgNO3 reveals that accumulated silver is mainly present as ions.
Nanoparticles induce dermal and intestinal innate immune system responses in zebrafish embryos
Metal and plastic nanoparticles elicit innate immune responses in the skin and intestine of zebrafish embryos potentially serving as key event for AOPs.
Heteroaggregation of nanoplastic particles in the presence of inorganic colloids and natural organic matter
The presence and accumulation of micro- and nanoplastics in marine and fresh waters represent a huge environmental concern.
Emission and fate modelling framework for engineered nanoparticles in urban aquatic systems at high spatial and temporal resolution
The combination of emission and fate modelling improves the exposure assessment of engineered nanoparticles in complex urban systems.
