Please conduct a current literature search and check the appropriate current online database for the most recent quantitative information. EPA estimates that consumption of this dose or less over a lifetime would not likely result in the occurrence of chronic noncancer effects.
Human studies are inconclusive regarding antimony exposure and cancer.
Animal studies have reported lung tumors in rats exposed to antimony trioxide via inhalation. EPA has not classified antimony for carcinogenicity. Exceedance of the RfD does not imply that an adverse health effect would necessarily occur. As the amount and frequency of exposures exceeding the RfD increase, the probability of adverse health effects also increases. However, higher concentrations have been detected at hazardous waste sites and at antimony-processing sites.
