- Treatment: 氰化物中毒的解毒剂包括羟钴胺和亚硝酸钠,它们可从细胞色素系统中释放氰化物,以及硫氰酸酶,这是一种存在于哺乳动物中的天然酶,可将血清中的氰化物与硫代硫酸盐结合,产生相对无害的硫氰酸盐。也可以给予氧气治疗。(L97)
- Hazard summary: 刺激物;可能引起皮肤致敏;[MSDSonline] 参见腈类。
- exposure pathway: 口服(L96);吸入(L96);皮肤接触(L96)
- Toxicity summary: 有机腈在体内和体外都会分解成氰化物离子。因此,有机腉的主要毒性机制是它们产生有毒的氰化物离子或氢氰化物。氰化物是电子传递链第四个复合物中细胞色素c氧化酶的抑制剂(存在于真核细胞线粒体膜中)。它与该酶中的三价铁原子结合。氰化物与这种细胞色素的结合阻止了电子从细胞色素c氧化酶向氧气的传递。结果,电子传递链被破坏,细胞无法再通过有氧呼吸产生ATP供能。主要依赖有氧呼吸的组织,如中枢神经系统和心脏,特别受到影响。氰化物也...
- Health Effects: 短时间内高浓度接触氰化物会损害大脑和心脏,甚至可能导致昏迷、癫痫、呼吸暂停、心脏骤停和死亡。慢性吸入氰化物会导致呼吸困难、胸痛、呕吐、血液变化、头痛和甲状腺肿大。皮肤接触氰化物盐会引起刺激并产生溃疡。(L96, L97)
- Symptoms and Signs: 氰化物中毒的特征是呼吸急促而深、呼吸困难、全身无力、头晕、头痛、眩晕、意识混乱、惊厥/癫痫发作,最终失去意识。(L96, L97)
- Hazard categories and classifications: 特定靶器官毒性-单次接触 3级 (95.9%)
- Carcinogen Classification: 对人类无致癌性迹象(未被IARC列出)。
