11.TOXICOLOGICAL INFORMATION
Acute Toxicity	: LD50 > 2000mg/kg (Rats)
Ingestion(oral)
Inhalation	: No data
Dermal	: LD50>2000mg/kg(Rats)
Eye irritation	: Not an irritant (Rabbits)
Skin irritation	: Not an irritant (Rabbits)
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 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/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.
