Definition:
Bromine Monoxide (BrO) is one of many bromine (Br)-containing compounds that
occur in the atmosphere from both natural and anthropogenic sources. The major
source compounds are CH3Br (both natural and anthropogenic in origin), the
halons (manufactured for use as fire suppressants), and dibromomethane CH2Br2
(emitted from the oceans). Destruction of these compounds results in the
formation of a suite of inorganic Br-containing species, including bromine
atoms (Br), bromine monoxide (BrO), bromine nitrate (BrNO3), hypobromous acid
(HOBr), and hydrogen bromide (HBr). The chemistry that acts to interconvert
these inorganic species results in depletion of ozone in the stratosphere.
