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.
: 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
exposure group, and a minimal to mild degree of fibrosis was noted in 22% of the animals
in the middle (4mg/m
