  • 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.
