NIOSH announced a conference in July 2010 to discuss the safety concerns that have been raised concerning workers and nanotechnology.
“NIOSH research has shown that some nanoparticles, including certain types of carbon nanotubes and metal oxides, can be toxic to the heart and lung in mice and rats in laboratory experiments. Other research has demonstrated various other adverse effects of nanoparticles. Through its Approaches to Safe Nanotechnology, NIOSH recommends that specific precautions be taken to protect workers who might be exposed to any level of nanoparticles or nanoparticle-containing materials. A big question left unanswered is, can nanoparticles cause the same types of disease in humans?”
Concern intensified on this issue following the publication of the September issue of the “European Respiratory Journal, the first medical case series of workers with serious disease that the study authors associate with exposure to nano-sized particles has been published.”
