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
3
) exposure
group, and a minimal to mild degree of fibrosis was noted in 22% of the animals in the middle
(4mg/m
3
) exposure group, but no pulmonary change was reported in the lowest (1mg/m
3
)
exposure group, the most relevant level to potential human exposures.
