- Bromomethane, commonly known
as methyl bromide, is an organobromine compound with formula CH3Br.
- It is colorless, odorless,
nonflammable gas is produced both industrially and particularly
biologically.
- It has a tetrahedral shape
and it is a recognized ozone-depleting chemical.
- Bromomethane is found in the
ocean, where it is most likely formed by algae and kelp. Other names for
bromomethane include
methyl bromide, mono-bromomethane, and methyl
fume.
- Bromomethane is also a
precursor in the manufacture of other chemicals as a methylating agent,
and has been used as a solvent to extract oil from seeds and
wool.
- Bromomethane originates from
both natural and human sources. In the ocean, marine organisms are
estimated to produce 1-2 billion kilograms annually.
- It is also produced in small
quantities by certain terrestrial plants, such as members of the
Brassicaceae family.
- It is manufactured for
agricultural and industrial use by reacting methanol with hydrogen
bromide.
- The Methyl Bromide Recapture
System limits the maximum concentration of methyl bromide emitted in to
the atmosphere to 500 ppm, and reduces emissions during fumigation by up
to 97%.
- Bromomethane is used to kill
pests such as rats and bugs. It also kills fungi.
- Bromomethane is used to make
other chemicals and to get oil out of nuts, seeds and wool.
- Methyl bromide, which has
been in widespread use for some 30 years, is used for all types of
stored dry foodstuffs, particularly for produce in bags, cases or other
packages.
- Its use for large loose
bulks of foodstuff, when it may be used alone or in admixture with
ethylene dibromide or with carbon
tetrachloride, is more limited.
- It is also used for the
treatment of soil before sowing or planting, especially in glasshouses,
against nematodes, weeds and other
organisms and also in plant
quarantine operations, including disinfestation of fresh fruit and
vegetables.
- Methyl bromide is one of the
top five most widely used pesticides in the world today.
- Eighty seven percent of
methyl bromide is used by farmers prior to planting to eradicate all
fungus, nematodes, microorganisms, and weeds from the soil to avoid
destruction of the crop.
- In the U.S., methyl bromide
is used mainly for tomato, strawberry, and bell pepper crops. California
is the largest user, followed by Florida.
- Methyl bromide in the
stratosphere comes from both natural and anthropogenic sources on earth.
Natural sources of methyl bromide,
such as the ocean, plants, and
soil, can also be a sink for this material.
- Methyl bromide use is
currently being reduced because of its ability to destroy the ozone
layer.
- The United States, Italy,
Japan, Israel, and Spain are the largest consumers of methyl bromide for
pre-plant soil applications. Together, these countries comprise
nearly 70 percent of methyl bromide consumption for this end use.
- In the U.S., about 21,000
tons (42,000,000 pounds) of methyl bromide are used annually in
agriculture, primarily for soil fumigation, as well as for commodity and
quarantine treatment, and structural fumigation.
- Globally, about 72,000 tons
(143,000,000 pounds) are used
each year, with North American use the
highest (38%), followed by Europe (28%), Asia (22% - includes Israel and
the Mid-East), with
South America and Africa combined using the
least (12%).
- Until its production and use
were curtailed by the Montreal Protocol, bromomethane was widely applied
as a soil sterilant, mainly for production of seed but also for some
crops such as strawberries and almonds.
- In Australia, methyl bromide
is the preferred fumigant required by the Australian Quarantine and
Inspection Service (AQIS) for most organic goods imported into
Australia.
