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.
