CHAPTER 13. ACID RAIN - Harvard University

Sulfur dioxide (SO2) is emitted from the combustion of sulfur-containing fuels (coal and oil) and from the smelting of sulfur-containing ores (mostly copper, lead, and zinc). In the atmosphere, SO2 is oxidized by OH to produce H2SO4: (R10) (R11) (R12) The lifetime of SO2 against reaction with OH is 1-2 weeks.
