Nanotechnology Risk Screening and Decision Support
The responsible development of new nanomaterials and nano-enabled products requires that potential risks are understood and managed before harms occur. While predictive tools for anticipating human health and environmental risk are in early stages of development, there is a clear need for screening methodologies to inform decision-making related to nanomaterial risk management in regulatory agencies and industry.
We designed and facilitated a Structured Decision Making process that drew upon expertise in nano-toxicology, human exposure, and environmental fate and transport to develop a preliminary Nano Risk Screening Tool (NRST). This decision-support framework relates key nanomaterial and product characteristics to important hazard and exposure indicators, providing a transparent and adaptable screening tool to aid risk managers’ decisions under uncertainty.
