  ATSDR - MMG: Methyl Bromide
Methyl bromide is used primarily as a pesticide to fumigate soil, spaces, structures, and commodities.
Exposure to high concentrations of pure methyl bromide may cause inflammation of the bronchi or lungs, an accumulation of fluid in the lung, and irritation of the eyes and nose.
Methyl bromide is a neurotoxic gas that may cause headaches, dizziness, visual disturbances, ventricular fibrillation, pulmonary edema, ataxia, convulsions, coma, and death.

 Potassium bromide - Wikipedia, the free encyclopedia
Potassium bromide (KBr) is a salt, used as an anticonvulsant and a sedative in the 1800s.
Potassium bromide is a typical ionic salt which is fully dissociated and pH7 in aqueous solution.
It is also sometimes used as a bromide source in organic synthesis, since it is less hygroscopic than sodium bromide.

 Bromide Therapy
Madison, WI Bromide is a halide element with anticonvulsant properties that is gaining widespread use for the treatment of seizures in dogs.
Bromide is one of the few drugs that has been shown to be effective in dogs with seizures that are refractory to standard therapeutic serum concentrations of phenobarbital.
Although a reduction instead in the dose of bromide can also be considered, the goal in most patients is to reach therapeutic serum bromide concentrations and to reduce the dose of phenobarbital over time, so that a dose reduction in phenobarbital is preferred.

 Methyl bromide (Bromomethane) (HSG 86, 1994)
Some of this methyl bromide is broken down in the lower atmosphere (troposphere), and some diffuses upwards to the stratosphere where it decomposes (photolysis) and produces active bromine species that react with ozone and are partly responsible for the depletion of the ozone layer.
In soil, methyl bromide is partly hydrolysed to bromide ions.
Methyl bromide is degraded in soil by hydrolysis and microbial degradation.

Methyl bromide absorbed into the body quickly releases bromide ion, which can be measured in the blood.
However, the relationship between long-term methyl bromide exposure and the level of bromide ion in the blood is not well known.
Sometimes methyl bromide is mixed with a strong-smelling, irritating gas (chloropicrin) to provide a warning of exposure; however, sometimes there are dangerous levels of methyl bromide without enough chloropicrin to warn you that you are being exposed.
