Toxicology
Treatment
EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.
Chemistry & industry
Pharmacology
Metabolism/Metabolites
Uranium is absorbed in low amounts via oral, inhalation, and dermal routes. Uranium in body fluids generally exists as the uranyl ion (UO2)2+ complexed with anions, such as citrate and bicarbonate, or plasma proteins. Uranium preferentially distributes to bone, liver, and kidney. The large majority of uranium that enters the body is not absorbed and is eliminated from the body via the urine and faeces. (L248)
