Sulfur dioxide: Sources of emissions
Industry sources
Fossil fuel combustion sites particularly coal burning power plants; industrial processes such as wood pulping, paper manufacture, petroleum and metal refining and metal smelting, particularly from sulfide containing ores, e.g. lead, silver and zinc ores all emit sulfur dioxide to air.
Diffuse sources, and industry sources included in diffuse emissions data
Small textile bleaching and food preserving facilities and wineries, fumigation activities all emit sulfur dioxide to air.
Natural sources
Geothermal activity, including hot springs and volcanic activity; sulfur dioxide is produced from the natural decay of vegetation on land, in wetlands and in oceans all emit sulfur dioxide to air.
Transport sources
Vehicle exhaust.
Consumer products
Some solvents, dechlorination agents, bleaches and fumigation products.
