The 34 pages that link to Sulfur dioxide, each with the reason it gives.
Acid rainRelated: Atmospheric oxidation of this pollutant produces sulfuric acid in acid rain.
Fossil fuelRelated: Burning sulfur-bearing coal and oil can release this air pollutant.
Deccan TrapsRelated: Its short-lived cooling effects may have countered volcanic carbon warming.
SmeltingRelated: Roasting and smelting sulfide ores can release it unless captured.
Flue-gas desulfurizationRelated: It is the principal pollutant targeted by flue-gas desulfurization.
Copper smeltingRelated: Oxidizing sulfide ore releases sulfur dioxide, a major smelter emission.
Volcanic outgassingRelated: Its atmospheric reactions can form sulfate aerosols that alter climate.
Dried fruitRelated: Sulfiting can preserve the color of fruits such as apricots during drying.
Sulfur monoxideRelated: SO can be oxidized to this familiar, more stable sulfur oxide.
Thiosulfuric acidRelated: It is one of the products associated with thiosulfuric acid decomposition.
