Finnish Institute of Occupational Health Releases Report on MWCNTs

The Finnish Institute of Occupational Health released a report in October 2013 entitled Evaluation of the health effects of carbon nanotubes. See http://www.ttl.fi/en/publications/Electronic_publications/Pages/Evaluation_of_the_health_effects_of_carbon_nanotubes.aspx According to the Institute, recent studies have suggested that some types of multiwalled carbon nanotubes (MWCNT) have similar effects as asbestos. The Institute states that the report "shows that rigid, long and needle-like MWCNTs induce inflammation and DNA damage in the lungs and in cultured cells, while flexible, long and tangled MWCNTs do not. It appears that the rigidity of MWCNTs is a key feature in triggering a specific inflammatory reaction and in causing cellular alterations involved in cancer formation." The Institute states that this new information on the adverse effects of MWCNTs will be useful in assessing which forms of MWCNTs require regulatory attention and special safety measures in occupational settings.
