Bromine (Br) is a chemical element in the halogen element group. At ambient
temperature bromine is a brownish-red liquid. It has a similarly colored vapor with an
offensive and suffocating odor. It is the only nonmetallic element that is liquid under
ordinary conditions and it evaporates easily at standard temperature and pressures.
Elemental bromine is corrosive and toxic, with properties between those of chlorine
and iodine. Free bromine does not occur in nature, but occurs as colorless soluble
crystalline mineral halide salts, analogous to table salt.
Bromine is a naturally occurring element that can be found in many inorganic
substances. Humans many years ago began introducing organic bromines into
the environment.
These compounds are not natural and can cause serious harm to human health and
the environment. Bromine is corrosive to human tissue in a liquid state and its vapors
irritate eyes and throat. Bromine vapors are very toxic with inhalation.

Industrial Applications
Flame Retardants
Brominated flame retardants are an important commodity of growing importance
and the most common use of bromine. When brominated material burns, the flame
retardant produces hydrobromic acid, which interferes in the radical chain reaction of
the oxidation reaction of the fire. The mechanism is that the highly reactive hydrogen
oxygen and hydroxyl radicals react with hydrobromic acid and form less reactive,
bromine radicals (free bromine atoms). These also react with radicals in the first to
help terminate the reaction.

Gasoline Additives
Ethylene bromide was once a common additive to gasolines containing lead
anti-knock agents. It scavenges lead by forming volatile lead bromide, which is then
released as exhaust from the engine. This application accounted for 77% of the
bromine uses in 1966 in the United States. This application has declined since the
1970s due to environmental regulations. These volatile organic compounds (VOCs)
now are regulated as ozone depletion agents.
Drilling Fluids
The bromides of calcium, sodium, and zinc account for a sizable part of the bromine
market. These salts form dense solutions in water that are used as drilling fluids
sometimes called clear brine fluids.
Coal-Fired Power Plants
Bromine is also used to reduce mercury pollution from coal-fired power plants. This
can be achieved either by treating activated carbon with bromine or by injecting
bromine compounds onto the coal prior to combustion.
Spa Maintenance
Like chlorine, bromine is used in maintenance of swimming pools and hot tubs,
where it is generated onsite from a bromide plus hydrogen peroxide. The high water
temperature renders chlorinated water purification and buffering compounds unstable.
Bromine compounds may also improve the life of free-halogen antimicrobials.
Other Uses
Several dyes, agrichemicals, and pharmaceuticals are organo-bromo compounds.
