Toxicity Profile
Route of ExposureOral (3) ; inhalation (3) ; dermal (3)
Mechanism of ToxicityInorganic and organic tin compounds are weak inhibitors of alcohol dehydrogenase. (1)
MetabolismThough tin metal is very poorly absorbed, tin compounds may be absorbed via oral, inhalation, or dermal routes, with organotin compounds being much more readily absorbed than inorganic tin compounds. Tin may enter the bloodstream and bind to hemoglobin, where it is distributed and accumulates mainly in the kidney, liver, lung, and bone. Tin and its metabolites are excreted mainly in the urine and feces. (3)
Toxicity ValuesLD50: 41 mg/kg (Intraperitoneal, Mouse) (7) LD50: 10 g/kg (Oral, Rabbit ) (6) LD50: 17 800 ug/kg (Intravenous, Mouse) (6)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesTin(II) chloride is used for the tin-plating of steel when making tin cans, for textile dyeing, as a catalyst in the production of the plastic polylactic acid, as a reducing agent, in organic chemistry, and as a food additive, serving as a color-retention agent and antioxidant. (5)
Minimum Risk LevelNot Available
Health EffectsIngestion of large amounts of inorganic tin compounds can cause stomachache, anemia, and liver and kidney problems. (2, 3)
SymptomsInorganic or organic tin compounds placed on the skin or in the eyes can produce skin and eye irritation. (3)
TreatmentEYES: 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.
