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.

Chronic Effect
: In a study in rats of chronic inhalation exposure to a typical toner, a mild to moderate
degree of lung fibrosis was observed in 92% of the rats in the high concentration
(16mg/m

reported in the lowest (1mg/m

human exposures.
