Carbon Nanotubes: Canary In The Mine?

This post was written by Antony Klapper, Margaret L. Sanner and Jesse Ash.

In June 2008, scientists at the University of Edinburgh Centre for Inflammatory Research, the Woodrow Wilson International Center for Scholars and other locations released results from a study linking carbon nanotube (CNT) exposure in mice to the development of cell pathologies associated with asbestos exposure.

The widely publicized research specifically found that exposing the mesothelial lining of the body cavity of mice to long-fibered CNTs results in asbestos-like pathogenic behavior, including the formation of cell lesions of the type which are known precursers to mesothelioma development in humans.

Recent Nanotechnology Developments: Finding a Middle Ground Between Identifying Real Health Concerns and Reacting to Alarmist Rhetoric

In May 2008, scientists released results from a study linking carbon nanotube (CNT) exposure in mice to the development of cell pathologies identified as possible precursors to mesothelioma in humans.  The findings made international news, with the New York Times, Washington Post, the L.A. Times, BBC and AFP all reporting on it.

It must have been a slow news day, because this was not new news.

As the authors in the study made clear, the results were “predicted,” given what scientists already knew about the inflammatory effect of long, thin, fiber-shaped substances.  In fact, in 2007, Reed Smith attorneys wrote about the parallels that others have drawn between CNTs and asbestos, citing an even earlier (2004) British report.
