EHP Includes Nanoparticles Correspendence and Article Regarding Nanotubes

Lynn L. Bergeson

The April 1, 2008, issue of Environmental Health Perspectives (EHP) includes correspondence regarding a 2007 EHP article concerning the aggregation and toxicology of titanium dioxide nanoparticles, as well as the authors’ response. The issue also includes an article entitled “Ecological Uptake and Depuration of Carbon Nanotubes by Lumbriculus variegatus.” The authors synthesized radioactively labeled nanotubes using a novel methane chemical vapor deposition procedure. According to the authors, the results suggest that purified carbon nanotubes do not readily absorb into organism tissues.
