Nanomaterial Risk Screening: A Structured Approach to
Aid Decision Making under Uncertainty1
Nanomaterial Risk Screening Tool (NRST)
Two-day workshop conducted in May 2012 that engaged
experts from the nanotoxicology, human exposure, and
environmental fate and transport domains
Utilized a Structured Decision Making (SDM) approach to
create a conceptual framework (see inset) and decision
support tool concept (NRST) to aid in the collection,
organization, and contextualization of risk information
Identified key pathways of effects linking intrinsic and
extrinsic nanomaterial physicochemical properties with
hazard and exposure indicators
Developed a qualitative risk scoring scheme to aid in
evaluation of risks to human health and environment from
engineered nanomaterials (ENMs) across their life cycle.
Results
The NRST decision tool is designed to enable decision
makers to make inferences about the health and
environmental implications of ENMs and ENM enabled
products under uncertainty.
