代谢

溴主要通过吸入进入人体，但也可以通过皮肤接触。溴盐可以摄入。由于溴的活性，它会迅速形成溴化物并可能沉积在组织中，取代其他卤素。

Bromine is mainly absorbed via inhalation, but may also enter the body through dermal contact. Bromine salts can be ingested. Due to its reactivity, bromine quickly forms bromide and may be deposited in the tissues, displacing other halogens. (L626)

毒理性

• 毒性总结

溴是一种强大的氧化剂，能够从粘膜的水分中释放出氧自由基。这些自由基也是有力的氧化剂，能够造成组织损伤。此外，氢溴酸和溴酸的形成将导致二次刺激。溴离子还已知会影响中枢神经系统，导致溴中毒。这被认为是溴离子取代神经递质和传输系统中的氯离子的结果，从而影响许多突触过程。（L626, L627, A543）

Bromine is a powerful oxidizing agent and is able to release oxygen free radicals from the water in mucous membranes. These free radicals are also potent oxidizers and produce tissue damage. In additon, the formation of hydrobromic and bromic acids will result in secondary irritation. The bromide ion is also known to affect the central nervous system, causing bromism. This is believed to be a result of bromide ions substituting for chloride ions in the in actions of neurotransmitters and transport systems, thus affecting numerous synaptic processes.

毒理性

• 健康影响

溴蒸气会引起刺激和对粘膜的直接损害。元素溴也会烧伤皮肤。溴化物离子是一种中枢神经系统抑制剂，长期暴露会产生神经元效应。这被称为溴中毒，可能导致从中睡意到昏迷、恶病质、昏迷、反射丧失或病理反射、阵挛性癫痫、震颤、共济失调、神经敏感性丧失、瘫痪、眼乳头水肿、言语异常、脑水肿、谵妄、攻击性和精神病的中心反应。

Bromine vapour causes irritation and direct damage to the mucous membranes. Elemental bromine also burns the skin. The bromide ion is a central nervous system depressant and chronic exposure produces neuronal effects. This is called bromism and can result in central reactions reaching from somnolence to coma, cachexia, exicosis, loss of reflexes or pathologic reflexes, clonic seizures, tremor, ataxia, loss of neural sensitivity, paresis, papillar edema of the eyes, abnormal speech, cerebral edema, delirium, aggressiveness, and psychoses.

• 症状

溴蒸气会引起刺激和对粘膜的直接损害。症状包括流泪、流鼻涕、眼部刺激伴有来自咽和上呼吸道的粘液分泌、咳嗽、呼吸困难、窒息、喘息、鼻出血和头痛。溴离子是一种中枢神经系统抑制剂，会引起共济失调、言语不清、震颤、恶心、呕吐、乏力、眩晕、视觉障碍、不稳、头痛、记忆和注意力受损、定向障碍和幻觉。这被称为溴中毒。

Bromine vapour causes irritation and direct damage to the mucous membranes. Symptoms include lacrimation, rhinorrhoea, eye irritation with mucous secretions from the oropharyngeal and upper airways, coughing, dyspnoea, choking, wheezing, epistaxis, and headache. The bromide ion is a central nervous system depressant producing ataxia, slurred speech, tremor, nausea, vomiting, lethargy, dizziness, visual disturbances, unsteadiness, headaches, impaired memory and concentration, disorientation and hallucinations. This is called bromism. (L626, L627)
