Parallel session 2B: Environmental exposure, release & fate
A decade of research on nanomaterial fate and exposure has led to greater understanding of the environmental fate of nanomaterials, their potential risks (and benefits), and an overall better understanding of the role of nanophase materials in environmental processes such as nutrient cycling. This research has also led to a better understanding of how the system complexity makes predicting...

Parallel session 2B: Environmental exposure, release & fate
Material flow modeling constitutes an important tool to predict and understand the flows of materials through the technosphere into the environment. We present a new ╲Dynamic Probabilistic Material Flow Assessment (DPMFA) method, combining dynamic material flow modeling with probabilistic modeling. The new method represents a significant step forward compared to established MFA or dynamic...

Discharging combined sewer overflows (CSOs) directly or with minimal treatment into water bodies could elevate the concentrations of nanomaterials (NMs) in the receiving environment as a result of their extensive use in wide range of products. Among different NM types, fullerenes (C60) have been shown to pose risks on humans and aquatic organisms. Consequently, their fate and removal pathways...

Currently little is known about engineered nanomaterial (ENM) concentrations in the environment. In 2009, we reported the first environmental concentrations for different ENM by applying probabilistic material flow modelling, which was recently updated to yield more comprehensive and up-to-date environmental concentrations of ENM. However, the used models are static and do not consider...

Parallel session 2B: Environmental exposure, release & fate
There has been a lot of debate in recent years regarding appropriate fate descriptors for engineered nanoparticles (ENPs), needed to predict ENP concentrations and transport in different environmental compartments. It is tempting to simply apply concepts for conventional organic pollutants, such as the use of equilibrium partition coefficients (e.g. Kow, Kd) in fate and risk assessment of...
