代谢

吸收的锑通过血液运输到身体的各个组织部位；在头发和皮肤中发现的含量最高；肾上腺、肺、大肠、气管、小脑和肾脏也含有相对较高的锑含量。锑可以与巯基和磷酸基团共价相互作用，以及与许多内源性配体（例如，蛋白质）的可逆结合相互作用。目前尚不清楚这些相互作用在毒理学上是否具有重要意义。锑是一种金属，因此不会发生分解代谢。锑通过尿液和粪便排出体外。部分粪便中的锑可能代表未被吸收的锑，这些锑通过粘膜纤毛活动从肺部清除，进入食道再到胃肠道。(L741)

Absorbed antimony is transported to various tissue compartments of the body via the blood; the highest levels are found in the hair and skin; the adrenal glands, lung, large intestine, trachea, cerebellum, and kidneys also contain relatively high levels of antimony. 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 a metal and, therefore, does not undergo catabolism. 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. (L741)

• 毒性总结

吸入数据显示，心肌是锑中毒的目标。锑可能通过干扰糖原分解和糖异生途径的酶来影响循环葡萄糖。锑的作用机制尚不清楚。然而，一些研究表明，锑与巯基团结合，包括那些对组织呼吸重要的几种酶中的巯基团。BAL（2,3-二巯基丙醇）的解毒作用取决于其阻止或破坏锑与关键酶结合的能力。此外，死亡原因被认为与急性砷中毒基本相同。(T18, L741, A238)

The 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 (2,3-dimercaptopropanol) depends on its ability to prevent or break the union between antimony and vital enzymes. Moreover, the cause of death is believed to be essentially the same as that in acute arsenic poisoning. (T18, L741, A238)

毒理性

• 健康影响

皮肤接触锑可以导致锑斑（围绕汗腺和皮脂腺的丘疹和脓疱）。锑中毒还可能导致肺尘埃沉着病。吸入锑可能导致肺部功能改变和其他影响，包括慢性支气管炎、慢性肺气肿、活动性肺结核、胸膜粘连和刺激。锑中毒还可能导致血压升高。心肌抑制、血管扩张和体液流失可能导致低血压、电解质紊乱和急性肾衰竭的休克。脑水肿、昏迷、抽搐和死亡也是可能的。（L741）

Dermal 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.

• 症状

腹部疼痛、呕吐、腹泻可能是由吸入锑引起的。呼吸困难、头痛、呕吐、咳嗽、结膜炎和鼻出血脓性分泌物可能是由吸入暴露引起的。皮肤或眼睛接触可能会导致暴露表面疼痛和发红。（T64, L741）

Abdominal 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. (T64, L741)
