from conventional materials.\u00a0 <!--more-->Additionally, rats exposed to the fine dust fared no worse whether the material contained nano-components or not.\u00a0 The team subjected four materials \u2013 two thermoplastic and two cements infused with different nanostructures \u2013 to high speed sanding, gentle abrasion and UV radiation, with an eye toward consumer exposure.\u00a0 Andrew Maynard, professor of environmental health sciences at\u00a0the University of Michigan, United States, said the results were to be expected as nano-components are very tightly bound to the plastic and cement.\u00a0 \u201cWe cannot be complacent and assume that there is no release or subsequent risk here &#8211; there need to be studies, and this is one that helps inch the state of knowledge forward,\u201d he said.\u00a0 Wendel Wohlleben, one of the BASF researchers, said the rat study was preliminary as it was limited by the amount of powder available, but the results suggest that the nano-components do not increase the hazards of inhaling the material.\u00a0 \u201cThe statistics will be improved in further studies, but for the first time, we have experimentally determined all elements of a risk assessment of nano-composites,\u201d he added.\u00a0<\/p>\n<p><a
