- Toxicity summary： 溴是一种强氧化剂，能够从粘膜的水中释放氧自由基。这些自由基也是强氧化剂，会造成组织损伤。此外，氢溴酸和溴酸的形成会导致继发性刺激。溴离子也已知会影响中枢神经系统，导致溴中毒。据信这是溴离子在神经递质和转运系统的作用中替代氯离子的结果，从而影响许多突触过程。(L626, L627, A543)
- Health Effects： 溴蒸气对粘膜有刺激性和直接损害。元素溴也会灼伤皮肤。溴离子是中枢神经系统抑制剂，长期接触会产生神经效应。这称为溴中毒，可导致从嗜睡到昏迷、恶病质、脱水、反射丧失或病理性反射、阵挛性癫痫发作、震颤、共济失调、神经敏感性丧失、轻瘫、眼睛乳头水肿、言语异常、脑水肿、谵妄、攻击性和精神病等中枢反应。(L625, L626, L627)
