Carcinogenicity
:In 1996 the IARC reevaluated carbon black as a Group 2B carcinogen 
(possible human carcinogen). This classification is given to chemicals for 
which there is inadequate human evidence, but sufficient animal evidence 
on which to base an opinion of carcinogenicity. The classification is based 
upon the development of lung tumors in rats receiving chronic inhalation 
exposures to free carbon black at levels that induce particle overload of the 
lung. Studies performed in animal models other than rats did not show any 
association between carbon black and lung tumors. Moreover, a two-year 
cancer bioassay using a typical toner preparation containing carbon black 
demonstrated no association between toner exposure and tumor 
development in rats.
