Vanadium(III) bromide is a chemical compound of vanadium and bromine. Bromine is a halogen element with the symbol Br and atomic number 35. Diatomic bromine does not occur naturally, but bromine salts can be found in crustal rock. Vanadium is a transition metal with the chemical symbol V and atomic number 23. The element usually combines with other elements such as oxygen, sodium, sulfur, or chloride, and occurs naturally in about 65 different minerals and in fossil fuel deposits. Vanadium is found in many organisms, and is used by some life forms as an active center of enzymes. (L837, L838, L625)

Toxicity

Toxicity
7
Symptoms
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. Inhalation of vanadium causes lung irritation, coughing, wheezing, chest pain, runny nose, and a sore throat. (L837, L626, L627)
Treatment
EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.
Health Effects
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. Breathing high levels of vanadium affects the lungs, throat, and eyes. Ingestion of vanadium may cause kidney and liver damage, birth defects, or death. (L837,L625, L626, L627)
Exposure Routes
Oral (L626); inhalation (L626); dermal (L626)
Toxicity Summary
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. Vanadium damages alveolar macrophages by decreasing the macrophage membrane integrity, thus impairing the cells' phagocytotic ability and viability. The pentavalent form of vanadium, vanadate, is a potent inhibitor of the Ca+-ATPase and Na+,...
