Risk Assessment for Infrastructure

In this issue of Trends, we discuss new frontiers in risk assessment.

The first article discusses risk assessment in infrastructure, and some of the unique exposure scenarios that arise with these large-scale and complex projects.  The second article is about evaluating human health and environmental risks associated with recycled products, specifically “beneficial use” assessments of building material containing coal combustion products.  The third article discusses a risk assessment method performed on medical devices called extractables and leachables (E&L) testing, and describes ways scientists can characterize and address the uncertainties that come from this testing method.

Gradient contributors to this issue include Grace Greenberg, M.P.H.; Julie Lemay, M.P.H.; Andrew Bittner, M.Eng., P.E.; Ari Lewis, M.S.; Matthew Lewis, M.S.; and Dr. Joel Cohen.  Our guest editor is Craig Heidrich, Founder and Managing Director of HBM Group, an Australian-based professional association management company, who discusses efforts in Australia to characterize naturally occurring radioactive materials (NORM) in coal combustion products and to comply with guidelines and regulations for NORM.

We hope this issue of Trends will give you new insights on these evolving applications for risk assessment methods.
