“…These data indicate that secondary sulphate is the predominant factor responsible for the visibility degradation apparent over the past two decades. The chemical mechanism of S(IV) to S(VI) transformation has been described extensively (e.g., Penkett et al, 1979;Stockwell and Calvert, 1983;Liang and Jacobson, 1999;Seinfeld and Pandis, 2006). The major pathways for atmospheric S(IV) oxidation are gas-phase oxidation of SO 2 by OH radical and aqueous oxidation of dissolved SO 2 with dissolved H 2 O 2 or O 3.…”

“…The aqueous-phase oxidation of sulfur dioxide has been frequently studied (Penkett et al, 1979;Chameides, 1984;Jacob, 19861, indicating the importance of aqueous phase conversion of SO, to SO:-in fogs and clouds. However, investigations of the oxidation pathways of SO, in wet aerosols have shown that aerosol phase chemistry is not as important as a sulfate generation mechanism as the gas-phase pathway in daytime (Middleton et al, 1980;Peterson and Seinfeld, 1980;Saxena and Seigneur, 1987).…”

“…The chemical mechanism of S(IV) to S(VI) transformation has been extensively studied in literatures (e.g. Penkett et al, 1979; www.intechopen.com Stockwell and Calvert, 1983;Seinfeld and Pandis, 1998;Liang and Jacobson, 1999). The enhanced formation of secondary sulfate in the O 3 -rich atmosphere mentioned above actually agrees with the findings from a recent study, in which SO 4 2-concentrations in East Asia were found to increase at a greater rate than SO 2 emissions and SO 2 concentrations because "East Asia is a less oxidant-limited area than other parts of the world" (Lu et al 2010).…”
