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. (Muhle et al.)
The quantity of toner exhausted with the normal use of this product is estimated less than 1mg/
m3 per day.
