NTP 1997 Study of inhalation of molybdenum<br />
trioxide in rats and mice, only effect on body<br />
weight was noticed at 300 mg.m-3. After 2 year<br />
inhalation exposure of 30 mg.m-3. Concluded<br />
changes are similar to other inhalation studies<br />
of particulate compounds and not caused by the<br />
molybdenum trioxide.<br />
