安全性と法規制
| Treatment | In case of acute exposure, bromide salts should be washed with water from any areas of dermal or ocular contact. If inhaled, treatment is mainly symptomatic and may include maintaining an adequate airway, administering oxygen, antibronchospasm therapy, and/or antibiotics. (L626) |
|---|---|
| 健康影響 | 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. (L625, L626, L627) |
| 暴露経路 | Oral (L626)inhalation (L626)dermal (L626) |
| 毒性の概要 | 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. (L626, L627, A543) |
| Signs and Symptoms | 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. (L626, L627) |
| Carcinogen Classification | No indication of carcinogenicity (not listed by IARC). (L135) |

解説
臭素の陰イオンBr－．古い文献では臭素イオンと書かれたが，臭素陽イオンBr＋も存在するので，陰イオンBr－は臭化物イオンというのが正しい．
