Reactive Halogen Compounds in the Atmosphere [Hardcover]

Scientific evidence clearly shows that chlorine and bromine compounds, such as CFCs, released into the atmosphere are responsible for continuous and progressive global ozone losses superimposed by dramatic seasonal ozone depletions first observed over Antarctica, now occurring over Arctic regions as well. Today substitutes are produced and emitted, some of which are highly reactive substances. This handbook volume deals with these reactive halogen compounds and their interactions. It provides a review on the present knowledge of their properties, applications, sources, sinks as well as international regulations.P. Fabian and O.N. Singh: Reactive Bromine Compounds.- M.A.K.

These wonder compounds , drifting intact up to the stratosphere, are photolyzed there by the Sun's UV radiation releasing millions of tons of chlorine atoms each one capable of catalytically destroying thousands of ozone molecules. Scientific evidence clearly shows that chlorine and bromine compounds, such as CFCs, released into the atmosphere are responsible for continuous and progressing global ozone losses superimposed by dramatic seasonal ozone depletions over Antarctica and Arctic regions as well.
