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.
