Nanotechnology: Human and Environmental Exposure Assessment of Nanomaterials Workshop

Determining whether a material or substance poses an occupational health risk depends on knowing not only the potential toxic characteristics of the material, but also the characteristics of exposure. To what concentrations are workers exposed, for how long, and in what ways? In research to answer the question of whether nanomaterials pose work-related health risks, exposure assessment is particularly vital. Because of the relative newness of nanotechnology, very little exposure data have been reported in the scientific literature. At this stage, measuring or determining risk becomes a little like trying to solve a mystery when major clues are missing. Scientists and engineers face this challenge even as the market for nanotechnology grows, and along with it, an increasing demand from diverse parties for guidance to underpin its responsible development.
