Nanomaterials may show a broad range of material properties although having the same chemical composition. This raises the question, e.g. in the context of substance registration under REACH or during a risk assessment at the workplace, whether test result from the hazard assessment and gained knowledge of an exposure assessment of a certain material can be used to derive occupational hygiene measures. Goal of the project nanoGRAVUR, sponsored by the Federal Ministry of Education and Research (BMBF) is the development of criteria for the grouping of nanomaterials in view of their hazard to humans and the environment. Fibrous materials are at the centre of concern, for some materials a high potential of risk has already been demonstrated by animal testing. The contribution of BAuA therefore focuses on the determination and assessment of the dustiness behaviour and the development of a procedure to determine the exposure to nanoscale fibrous materials at the workplace.
