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.
fibrosis was observed in 92% of the rats in the high concentration (16mg/m
minimal to mild degree of fibrosis was noted in 22% of the animals in the middle (4mg/m
group, but no pulmonary change was reported in the lowest (1mg/m
level to potential human exposures.
