Study results indicate potential exposure to carbon nanomaterials in the facility visited, but preliminary data show little (if any) elevation of background nanoparticle concentrations. Similar results (Maynard et al., 2004) were found in a previous laboratory study on carbon nanotubes, which revealed the presence of particle agglomerates rather than individual nanoparticles. The physicochemical properties of nanomaterials are important because factors such as particle size, structure, and composition dictate the biological fate of the materials. These properties are also important with respect to the establishment of effective industrial hygiene measurement protocols and controls for nanomaterials, the health effects of which have not yet been elucidated.
