Toxicity to AnimalsFor Thorium Nitrate Anhydrous, (CAS number 13823-29-5): Acute oral toxicity (LD50): 1760 mg/kg [Mouse]. Chronic Effects on Humans May cause damage to the following organs: kidneys, lungs, bone marrow. Other Toxic Effects onHazardous in case of skin contact (irritant), of ingestion, of inhalation. Humans Special Remarks onNot available. Toxicity to Animals Special Remarks onMay cause adverse reproductive effects. Thorium reproductive effects, if they occur, are likely to be mediated by Chronic Effects on Humansionizing radiation. Thorium is a suspected carcinogen. Thorium Nitrate emits radiation which could cause cancer, but no evidence of cancer has yet been found. May affect genetic material (mutagenic) Special Remarks on otherAcute Potential Health Effects: Toxic Effects on HumansSkin: Causes skin irritation with a rash, or burning feeling on contact. Eyes: Causes eye irritation. Inhalation: It can irritate the respiratory tract (nose, throat). Ingestion: May be harmful if swallowed. It may cause nausea, vomiting, dizziness, abdominal cramps, ulceration or bleeding from the small intestine, bloody diarrhea, weakness, convulsions, general depression, headache, mental impairment. Chronic Potential Health Effects: Skin: May cause dermatitis. Ingestion and Inhalation: Repeated or prolonged exposure may affect the liver, kidneys, lungs, bone marrow. It may reduce the ability of the bone marrow to make blood cells. Prolonged or repeated inhalation may cause scarring of the lungs. Note: Thorium can accumulate in the bones, lungs and lymph system. Thorium that is absorbed into the body can remain for long periods of time and increase the risk of radiation induced cancer in tissues where it is retained. Thorium nitrate Section 12.
