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.

IARC has issued a notice that they will publish amonograph that lists titanium dioxide (tiO2) as
possibly carcinogenic to humans (Group 2B) by inhalation (based solely on animal data).
Human epidemiology studies do not suggest an increased risk of cancer in humans for
occupational exposure to titanium dioxide. IARC stated that exposure levels are assumed to be
lower in the user industries, with the possible exception of workers who handle large quantities
of titanium dioxide.
No significant exposure to titanium dioxide is thought to occur during the use of products in
which titanium dioxide is bound to other materials, such as in paints. 2)
