The course of asbestos litigation is well known, as is the fact that there appears to be no end in sight.  Is nanotechnology producing the next asbestos?  Some groups are working to prevent nanoparticle litigation from following in the steps of asbestos litigation.

In 2009, the United Kingdom’s Institute of Occupational Medicine (IOM) issued a report asking the question whether High Aspect Ratio Nanoparticles (HARN) – most notably, carbon nanotubes – create some of the same health risks as asbestos fibers.  The fiber-like features of HARN, although man-made rather than naturally occurring, may or may not interact with the human body in asbestos-like ways. The importance of determining whether HARN raise similar health risks cannot be overstated.  These issues have yet to be resolved, with potential health risks lurking in the interim.  As is often the case, development of new technology has flown past the scientific community’s ability to determine and assess the technology’s risks.

Looking back at the history of asbestos litigation, some burning questions need resolution sooner rather than later.  For example:

●  Do HARN fibers remain in vivo or do they degrade before disease processes are initiated?

●  If HARN are shown to persist in the body, what is the likely impact on workers?  In the asbestos context, the impact was seen in thousands of workers who developed debilitating progressive obstructive lung disease and/or malignant mesothelioma.  Do HARN have the capacity to produce similar health problems?

●  Even if HARN do not appear to behave directly like asbestos fibers, could HARN cause other, unknown, adverse health effects?

●  What broader impact might HARN have outside the workplace, including consumer and environmental exposures?

Are we headed down the same litigation road with HARN that we traveled with asbestos?

The asbestos litigation debacle in the United States began modestly enough with workers’ compensation claims, which were first denied and eventually routinely paid.  When asbestos insulation workers successfully brought actions against the manufacturers of the products they used in the workplace, the litigation expanded exponentially and has continued to challenge the court systems.

How can we avoid another asbestos?  The answer begins with research, knowledge, and awareness.
