Titanium (EHC 24, 1982) - INCHEM

Titanium dioxide (TiO 2) has been used as inert dust particles in lung clearance studies on animals (Ferin 1971a, 1971b, 1972; Ferin & Leach, 1973). Observations made 2 months after intratracheal injection of titanium dioxide (20 mg/animal) in rats did not reveal any reactions other than non-specific responses to dust particles (Göthe & Swensson, 1970).
