Nanotube-cancer concern

   May 26/June 2, 2008
Add a new potential risk to the list of health concerns about carbon nanotubes: asbestos-induced cancers.

A study shows that long carbon nanotubes introduced into the abdominal cavities of mice result in inflammation and lesions. The symptoms are the same as those typically caused by exposure to long asbestos fibers, and they raise questions about whether nanotubes could cause asbestos-related cancers and whether inhaling nanotubes poses a similar risk as inhaling asbestos fibers.
