Organic bromine compounds—another threat to the ozone layer

The ozone layer of the lower stratosphere is an extremely diffuse abundance of O3 that absorbs up to 99 percent of incoming ultraviolet solar radiation, thereby creating the conditions that make known life possible. In the 1970s and 1980s, as scientists reported the dramatic thinning of stratospheric ozone, a regulatory push by governments around the world led to a reduction in the use of chlorofluorocarbons by industry. Nonetheless, other compounds released into the atmosphere have the effect o
