Risk Assessment of Nanoparticles

Engineered nanoparticles are a rapidly growing technology and are increasingly found in a number of consumer goods. Nanoparticles can behave very differently to larger particles. They can be highly reactive and may have unusual thermal, optical or electromagnetic properties. For instance, the optical properties of zinc oxide nanoparticles makes them useful in sunscreens. There is a wide range of current and potential applications for this technology, for example in batteries, sunscreens, food products and semiconductors.

This POSTnote will set out the evidence regarding environmental and health impacts of engineered nanoparticles, and the current regulatory approaches towards risk assessment and their associated challenges.
