Additional Information: The results obtained from a Xerox' sponsored
Chronic Toner Inhalation Study, demonstrated no lung change in rats for the
3
lowest (1mg/m ) exposure level, the level most relevant to potential human
exposure). A very slight degree of fibrosis was noted in 25% of the animals at
3
the middle (4mg/m ) exposure level, while a slight degree of fibrosis was noted
3
in all the animals at the highest (16 mg/m ) exposure level. These findings are
attributed to "lung overloading", a generic response to excessive amounts of
any dust retained in the lungs for a prolonged period. This study was
conducted using a special test toner to comply with EPA testing protocol. The
test toner was 10 times more respirable than commercially available Xerox
toner, and would not be functionally suitable for Xerox equipment.
