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.
