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. (breakdown/formation) II. Photochemical Generation of Oxidants nfluenced by Latitude, Season, Diurnal Cycle Two General Types of Photochemical Reactions Direct Photolysis(light) = photons are absorbed by a chemical, resulting in the breakage or rearrangement of bonds (usually to the extended pi electron system)....
