Mapping out Nano Risks

The report of the “Mapping out Nano Risks” workshop held in Brussels in March is now available. There is a lot of good information in the report, put together by some well known names from recent debates over toxicology. One of the key conclusions was the need to distinguish between nanotechnologies and, specifically, to distinguish between free and fixed nanoparticles. Carbon nanotubes embedded in a polymer matrix, for example, pose a far lesser health risk than a vial of freshly produced nanotubes. Fixed nanoparticles won’t go anywhere by accident, but free ones may.
