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.
degree of lung fibrosis was observed in 92% of the rats in the high concentration
(16mg/m³) exposure group, and a minimal to mild degree of fibrosis was noted in
22% of the animals in the middle (4mg/m³) exposure group, but no pulmonary change
was reported in the lowest (1mg/m³) exposure group, the most relevant level to
potential human exposures.
