Iarc publishes nanomaterials monographs

The International Agency for Research on Cancer (Iarc) has published its monographs on carbon nanotubes, fluoro-edenite and silicon carbide. In 2014 the agency said: Mitsui-7 multiwalled carbon nanotubes (MWCNT-7) were a group 2B (possibly carcinogenic to humans) substance; Multiwalled carbon nanotubes (MWCNT) other than MWCNT-7 were a group 3 (not classifiable as to their carcinogenicity to humans) substance; Single walled carbon nanotubes (SWCNT) were a group 3 substance; Fluoro-edenite was a group 1 (carcinogenic to humans) substance; Silicon carbide was a group 1 substance with occupational exposures associated with the Acheson process; Fibrous silicon carbide was a group 2B substance; and Silicon carbide ‘whiskers’ were a group 2A (probably carcinogenic to humans) substance. In 2015 the Netherlands proposed a mandatory EU category 1B carcinogenicity classification for silicon carbide fibres.
