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.
