Toxicity Profile
Route of ExposureInhalation (6) ; oral (6) ; dermal (6)
Mechanism of ToxicityThe inhalation data suggests that the myocardium is a target of antimony toxicity. It is possible that antimony affects circulating glucose by interfering with enzymes of the glycogenolysis and gluconeogenesis pathways. The mechanism of action of antimony remains unclear. However, some studies suggest that antimony combines with sulfhydryl groups including those in several enzymes important for tissue respiration. The antidotal action of BAL depends on its ability to prevent or break the union between antimony and vital enzymes. Moreover, the The cause of death is believed to be essentially the same as that in acute arsenic poisoning. (2, 6, 1)
MetabolismAntimony is widely distributed throughout the body. The hair and skin contain the highest levels of antimony. The adrenal glands, lung, large intestine, trachea, cerebellum, and kidneys also contain relatively high levels of antimony. Blood is the main vehicle for the transport of absorbed antimony to various tissue compartments of the body. Antimony is a metal and, therefore, does not undergo catabolism. Antimony can covalently interact with sulfhydryl groups and phosphate, as well as numerous reversible binding interactions with endogenous ligands (e.g., proteins). It is not known if these interactions are toxicologically significant. Antimony is excreted via the urine and feces. Some of the fecal antimony may represent unabsorbed antimony that is cleared from the lung via mucociliary action into the esophagus to the gastrointestinal tract. (6)
Toxicity ValuesNot Available
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity (not listed by IARC). (5)
Uses/SourcesBreathing air, drinking water, and eating foods that contain antimony. Exposure can also occur through dermal or skin contact (6).
Minimum Risk LevelNot Available
Health EffectsDermal exposure to antimony can cause antimony spots (papules and pustules around sweat and sebaceous glands). Antimony poisoning can also lead to pneumoconiosis. Alterations in pulmonary function and other effects including chronic bronchitis, chronic emphysema, inactive tuberculosis, pleural adhesions, and irritation can result from inhalation of antimony. Increased blood pressure can also result from antimony poisoning. Myocardial depression, vasodilation and fluid loss may cause shock with hypotension, electrolyte disturbances and acute renal failure. Cerebral oedema, coma, convulsions, and death are possible. (6)
SymptomsAbdominal pain, vomiting, diarrhea can result from inhalation of antimony. Dyspnea, headache, vomiting,cough, conjunctivitis, and bloody purulent discharge from nose can result from inhalation exposure. Skin or eye contact can cause pain and redness of the exposed surface. (4, 6)
TreatmentFollowing oral exposure to antimony, administer charcoal as a slurry (240 mL water/30 g charcoal). Following inhalation exposure, move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. In case of eye exposure, irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. Following dermal exposure, Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician may need to examine the area if irritation or pain persists. (3)
