There have been a number of articles published since May 20 regarding a possible link between carbon nanotubes and the development of precursors of mesothelioma because of a recent letter published in Nature Nanotechnology.

C. Poland, et al., "Carbon nanotubes introduced into the abdominal cavity of mice show asbestos-like pathology in a pilot study," Nature Nanotechnology, May 20, 2008.


The letter’s authors related the results of an in vivo study in which they injected various types of carbon nanotubes into the mesothelial abdominal lining of mice. The study was driven, in part, because of prior speculation regarding a superficial resemblance between certain carbon nanotubes and asbestos fibers, as well as prior studies showing possible adverse EHS effects from exposure to certain types of carbon nanoparticles under laboratory conditions. While not actually causing mesothelioma, the scientists "observed that long MWCNTs produced inflamation FBGCs and granulomas similar to the foreign body inflammatory response caused by long asbestos fibres.“ Of course, the mice did not actually inhale carbon nanotubes (of any size) in the experiment, nor did the nanotubes end up in the chest cavity. The researchers further concluded that the "study does not address whether CNTs would be able to reach the mesothelium in sufficient numbers to cause mesothelioma following inhalation exposure.”

To those judging whether media coverage of the issue has been "fair and balanced," below are some of the more notable articles we have come across since the Poland study was published.
