Sulfur dioxide oxidation in winter orographic clouds

The production of sulfate in cloud droplets, and the attendant depletion of sulfur dioxide (SO2) oxidants were studied in wintertime orographic louds over southeastern Wyoming. By periodic (5-20 min) releases of SO 2 into the cloud the mixing ratio of SO 2 was raised to about double its background value of 0.7 parts per billion by volume (ppbv). Average values of the in-cloud reaction time, pse...

The formation of sulfur trioxide radical anion during the prostaglandin hydroperoxidase-catalyzed oxidation of bisulfite (hydrated sulfur dioxide).

The mechanism of prostaglandin synthase-dependent (bi)sulfite (hydrated sulfur dioxide) oxidation was investigated using an enzyme preparation derived from ram seminal vesicles. The horseradish peroxidase-catalyzed oxidation of (bi)sulfite was used as a model system. Incubation of (bi)sulfite with prostaglandin synthase and arachidonic acid, 15-hydroperoxyarachidonic acid, or H2O2 results in th...

Influence of ascorbic acid, sulfur dioxide and glutathione on oxidation product formation in wine-like systems

The impact of the addition of ascorbic acid, sulfur dioxide and glutathione on oxidation product formation under accelerated oxidative conditions was evaluated in model wines. The effects of these antioxidants have been compared in aqueous ethanol solutions containing (+)-catechin and metal ions at pH 3.2 by monitoring O2 consumption, color evolution by CIELab, as well as (+)-catechin and gluta...

Kinetics of Oxidation of Aqueous Sulfur(iv) by Nitrogen Dioxide

Although it is generally recognized that SOz and NOx (s NO + NOz) are the precursors of the strong acids (i.e., HzS04 and HN03) found in precipitation,! the detailed mechanisms for the oxidation of these compounds and their incorporation into atmospheric liquid water are not fully understood. In principle, the incorporation of acids into cloudor rainwater can take either or both of two pathways...
