Safety & regulation

Toxicology

Treatment · 1 item

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)

Health Effects · 1 item

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)

Exposure RoutesOral (L626) ; inhalation (L626) ; dermal (L626)

Toxicity Summary · 1 item

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 · 1 item

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 ClassificationNo indication of carcinogenicity (not listed by IARC). (L135)

Uses & manufacturing

UsesBromide is present in typical seawater (35 PSU) with a concentration of around 65 mg/L, which is around 0.2% of all dissolved salts. Bromide ions can be found in almost all living organisms, though it is not essential for life.
