We focus here on the mechanisms for oxidation of SO2 to H2SO4. 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: SO + OH + M fi HSO + M.
Acid rain is caused by nitrogen oxides and sulfur dioxide produced by both natural processes and the combustion of fossil fuels. Eventually, these oxides react with oxygen and water to give nitric acid and sulfuric acid.
3 lut 2023 · Acid rain, also called acid deposition, is a broad term for any form of precipitation with high concentrations of sulfuric and nitric acids. According to the Environmental Protection Agency (EPA), deposition can be wet such as in rain, fog, snow, mist, or dry, as in dust, gas, and smoke.
23 kwi 2015 · This abstract looks into the various aspects of acid rain, emphasizing its sources, consequences, and strategies used to lessen its harmful impacts. Anthropogenic emissions of sulfur dioxide...
Acid rain is rainfall whose pH is less than 5.6, the value typically observed, due to the presence of dissolved carbon dioxide. Acid rain is caused by nitrogen oxides and sulfur dioxide produced by both natural processes and the combustion of fossil fuels. Eventually, these oxides react with oxygen and water to give nitric acid and sulfuric acid.

1 sty 1988 · This review describes the more important features of the emission, chemistry, transport and deposition of pollutants involved in acid deposition. Global emissions, both natural and man-made, of sulphur and nitrogen oxides are discussed and examples of spatial distributions and trends over the last century presented.
