HEALTH HAZARD INFORMATION Effects of Exposure: To the best of our knowledge the chemical, physical and toxicological properties of praseodymium oxide have not been thoroughly investigated and recorded. Praseodymium is considered a rare earth metal. These metals are moderately to highly toxic. The symptoms of toxicity of the rare earth elements include writhing, ataxia, labored respiration, walking on the toes with arched back, and sedation. The rare earth elements exhibit low toxicity by ingestion exposure. May lead to production of skin and lung granulomas. Acute Effects: Inhalation: May cause irritation to the upper respiratory system. Ingestion: Considered to have low toxicity by ingestion. Skin: May cause irritation. Eye: May cause moderate irritation. Chronic Effects: Inhalation: May cause writhing, ataxia, labored respiration, sedation, pulmonary edema and lung granuloma. Ingestion: May act as a blood anticoagulant. Skin: No chronic health effects recorded. Eye: No chronic health effects recorded. Medical Conditions Possibly Aggravated by Overexposure: Pre-existing respiratory disorders Carcinogenicity NTP No IARC No OSHA No
