Engineered nanomaterials (ENMs, material containing
particles with at least one dimension less than 100 nm) are
present in a range of consumer products and could be
released into the environment from these products during
their production, use or end-of-life. The high surface to
volume ratio of nanomaterials imparts a high reactivity,
which is of interest for novel applications but may raise
concern for the environment. In the absence of
measurement methods, there is a need for modelling to
assess likely concentrations and fate arising from current
and future releases. To assess the capability that exists to
do such modelling, progress in modelling ENM fate since
2011 is reviewed. ENM-specific processes represented in
models are mainly limited to aggregation and, in some
instances, dissolution. Transformation processes (e.g.
sulphidation), the role of the manufactured coatings,
particle size distribution and particle form and state are still
usually excluded. Progress is also being made in modelling
ENMs at larger scales. Currently, models can give a
reasonable assessment of the fate of ENMs in the
environment, but a full understanding will likely require
fuller inclusion of these ENM-specific processes.- Organisation(en)
