Are carbon nanotubes safe or harmful

Carbon nanotubes, or CNT, are being used to make products stronger, lighter, faster, and more efficient. But are they safe? A growing body of research is raising concerns over the hazards presented by some forms of the material. As ever though, the risk to health depends on who is exposed to what and where, and how much they are exposed to. • This week's Risk Bites takes a look at factors that may affect how carbon nanotube toxicity is translated into risk. • Additional resources: • NIOSH (2013) New Findings on Lung Tumor Formation in Laboratory Mice Exposed to Multi-Walled Carbon Nanotubes. http://blogs.cdc.gov/niosh-science-bl... • What are carbon nanotubes used for? http://en.wikipedia.org/wiki/Potentia... • Donaldson et al.

We cover everything from understanding and balancing the risks and benefits of everyday products, to health science more broadly, to the potential impacts of emerging technologies, to making sense of risk perception.
