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...

Die in der Atmosphare eingebettete Ozonschicht lasst sich - nach fotochemischen Gesichtspunkten - 11 11 grob schematisch in zwei Bereiche aufgliedern, in das hohe Ozon oberhalb etwa 30 km und den Bereich unterhalb dieser Grenze, der die uberwiegende Ozonmenge enthalt. Im oberen Bereich 'ist das fur die Ozonbildung verantwortliche kurzwellige Sonnenlicht mit Wellen langen unter 2424 AE noch so ausreichend vorhanden, dass das fotochemische Gleichgewicht zwischen Ozonbildung und Ozonzerstorung sich in kurzer Zeit einstellt. Die Variationen dieses hohen Ozons sind im wesentlichen fotochemisch...

Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environmental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to...
