Mutagenicity | : | Negative (Ames Test) |
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 |
|
| 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/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.
