Methyl bromide is distributed in fat, lung, liver, adrenals, and kidney, with less distribution into brain. Methyl bromide is rapidly and extensively metabolized to methanol, bromide, and finally to CO 2. After oral or inhalation exposure in rats, 85% was eliminated within 65–72 h. Most (30–50%) was recovered as expired CO 2 and 4–20% as

Methyl bromide is ubiquitous in the environment, because it is generated naturally by oceans, biomass burning, and plants. For industrial purposes, methyl bromide is produced by direct bromination of methane and by the hydrobromination of methanol (Davis et al. 1977; O’Neil et al. 2001; Ioffe and Kampf 2002).Sulfur or hydrogen sulfide may be added as reducing agents to

Methyl bromide Ozonaction
Methyl bromide. Methyl bromide, an ozone depleting substance, was used extensively in the past as a fumigant for controlling a wide range of pests and pathogens present in soils (fungi, bacteria and soil-borne viruses), as well as in post-harvest storage of commodities, in buildings or structures (insects, mites, nematodes and rodents).

Introduction [2] Methyl bromide (CH 3 Br) is the largest single contributor of bromine to the stratosphere [Butler, 2000].The bromine from CH 3 Br is thought to deplete from 40 up to 100 times more ozone than chlorine (atom for atom) with the best estimate currently at 45 [Daniel et al., 1999].Therefore, despite its low atmospheric concentration, CH 3 Br is a
