| 11. TOXICOLOGICAL INFORMATION |
| ||
| Acute Toxicity | : LD50>2000mg/kg(Rats) | ||
| Ingestion(oral) | |||
| Dermal | : LD50>2000mg/kg(Rats) | ||
| Inhalation | : No data | ||
| Eye irritation | : Not an irritant | ||
| Skin irritation | : Not an irritant | ||
| Skin sensitizer | : No sensitization | ||
| 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 | |
|
|
| 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/m3) exposure group, and a minimal to mild degree of fibrosis was noted in22% 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.
