Unformatted text preview: Abiotic Reactions: Oxidation – Reduction Introduction to Environmental Transformations Photochemical Generation of Oxidants Oxidations Atmospheric Reactions Hydrospheric Reactions Reductions Hydrospheric Reactions Lithospheric Reactions Summary and Conclusions I. Introduction to Environmental Transformations Oxidation – loss of electrons or gain of oxygens. Reduction – gain of electrons or loss of oxygens. Hydrolysis – reaction with water (a nucleophile). Photolysis – transformation via sunlight. Pyrolysis/pyrogenesis – transformation by combustion. II. Photochemical Generation of Oxidants nfluenced by Latitude, Season, Diurnal Cycle Two General Types of Photochemical Reactions Direct (light) = photons are absorbed by a chemical, resulting in the breakage or rearrangement of bonds (usually to the extended pi electron system). Indirect (dark) = other chemicals (reaction with sunlight-generated oxidants such as HO . ). free radicals (oxidants) produced by light reactions react III. Oxidations III....
