Halogenated Hydrocarbons: Persistence, Toxicity, and Problems
Published in Richard J. Sundberg, The Chemical Century, 2017
In addition to the CFCs and HCFCs, bromomethane is also a significant contributor to ozone depletion. It is extensively used in treatment of soil to eliminate fungi and nematodes. It was included for phase-out with the CFCs in the 1987 Montreal protocols. Its annual use in the United States decreased from about 18 million kg to about 2 million kg by 2001. Use has continued under “critical use exemptions” based on the absence of alternatives. Bromomethane is also used extensively to fumigate warehouses and containers used in international shipments. There is evidence that workers can be exposed to excessive levels in the course of loading and unloading of treated containers.24

Methyl bromide (Bromomethane) is an odorless, sweetish, colorless gas that has been used as a soil fumigant and structural fumigant to control pests across a wide range of agricultural sectors. Methyl bromide is soluble in ethanol, benzene, carbon disulfide, and sparingly in water. During the 1920s, methyl bromide was used as an industrial fire extinguishing agent. The current uses of methyl bromide include the fumigation of homes and other structures for the control of termites and other pests.

Lignite sample was obtained from Inner Mongolia, China. The density composition of samples was analyzed by the float and sink experiments, which was carried out in centrifuges with different densities of heavy liquid prepared in different proportions of benzene, carbon tetrachloride, and three bromomethane. The result is shown in Figure 1.
