… The increasing use of engineered nanoparticles (ENPs) has led to growing concerns about
their environmental impacts. It has become a focus for researchers to explore their detection, …

… extent of environmental release. A number of risk assessment efforts have been made to
model and calculate predicted environmental concentrations (PECs) of nanoparticles with the …

… the quantities of engineered nanoparticles released into the environment. Three types of …
that the expected concentrations of different engineered nanoparticles in the environment are …

… concentration of freshwater. Consequently, in this case, they are mobile in an aqueous
environment. … possibly occur due to high ENPs concentration, water flow condition that facilitates …

… In this review we exhaustively cover all the studies quantifying environmental concentrations
of ENM until the beginning of 2013. Purely methodological discussions or qualitative results …

… environmental concentrations of engineered nanomaterials (ENMs) so that exposures can
be determined. Accurately assessing exposure potential to nanomaterials has significant …

… engineered nanoparticles are expected to occur in low particle number concentrations in the
environment… performed at more environmentally relevant concentrations, sensitive methods …

… Furthermore, quantitative analytical methods are required to determine environmental
concentrations and enable both effect and exposure assessments. Many methods still need …

… For example, higher velocity improves the collision frequency of the n-TiO 2 particles,
especially at a lower environmental concentration of ENPs. However, higher turbulence can result …

… some nanoparticles have the potential to induce harm in exposed aquatic organisms,
there is insufficient evidence for harm, for known/modelled environmental concentrations for …
