LD50 >5,000 mg/kg

Mutagenicity:

(Ames test) Negative (S.typhimurium Escherichia coli)

Carcinogenicity:

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/m

3

) exposure group, and a minimal to mild degree of 

fibrosis was noted in 22% of the animals in the middle (4mg/m

3

) exposure 

group, but no pulmonary change was reported in the lowest (1mg/m

3

) exposure 

group, the most relevant level to potential human exposures.
