Antimony trioxide causes pneumoconiosis in humans.
No lung tumors were seen in male rats. Both of these studies provide only qualitative evidence of carcinogenicity of antimony trioxide in rats. In 1994, Groth et al., conducted a third study using a more rigorous inhalation protocol. This study subjected rats to several test concentrations and antimony trioxide was not carcinogenic. Thus, there is only equivocal evidence for the carcinogenicity of antimony trioxide by the inhalation route.
