Peroxyl radicals are formed in biological systems, the atmosphere and aqueous waste and are important intermediates in the breakdown both of organic molecules and several inorganic species. As peroxyl radicals react with CFCs and HFCs in the atmosphere resulting in the further destruction of the ozone layer, there has been a great deal of progress towards understanding peroxyl radicals and their reactions in both the gas and liquid phase. Until now there has been no one volume which brings together all aspects of peroxyl radical chemistry - from their formation, to their wide and varied chemistry in the aqueous environment, biological systems, solid matrices, polymeric systems and the atmosphere. Peroxyl Radicals is essential reading for organic and physical organic chemists, biochemists and environmental technologists.

A collection of 16 papers bringing together aspects of peroxyl radical chemistry whose reaction with CFCs and HFCs in the atmosphere contribute to the destruction of the ozone layer. The research contributors outline peroxyl radicals and their reactions in both the gas and liquid phase, detailing their formation and structure, methodology for laboratory study, combinations and reactions in the gas phase, studies in aqueous solutions, biological and polymeric systems, their effect on the atmosphere, and in the treatment of waste solutions.

Peroxy radicals are formed in biological systems, the atmosphere and agueous waste and are important intermediates in the breakdown both of organic molecules and several inorganic species. The implications of their chemistry are far reaching and of great importance. Until now their has been no one volume which bring together all aspects of peroxy radical chemistry - from their formation, to their wide and varied chemistry in the aqueous environment, biological systems, solid matrices, polymeric systems and the atmosphere. Peroxy radicals react with CFCs and HFCs in the atmosphere, resulting in the further destruction of the ozone layer - a point which is of topical interest. Most carbon-centred radicals react with molecular oxygen with rate constants which are close to the diffusion-controlled limit, equal to k = 2-4 x 109 M-1s-1, to form peroxyl radicals-the peroxylation reaction:
