Sulfuric acid: Sources of emissions
Industry sources
The primary sources of sulfuric acid emissions are the industries that manufacture it or use it in production. Some of the industries that use it in production are the metal smelters, phosphate fertilizer producers, oil refiners, the chemical industry, battery manufacturers, manufacturers or fabricated metal products, manufacturers of electronic components, and manufacturers of measuring and controlling devices. These are emissions to the air unless there is a spill to water or land. Sulfuric acid spilt to land or water may result in emissions of the acid to air.
Diffuse sources, and industry sources included in diffuse emissions data
Other possible emitters of sulfuric acid are home and larger pool treatment, the disposal of automobile batteries, electroplating facilities, electronics, semiconductor and circuit board production, potato growers, and water and waste water treatment. These emissions may be to the soil, water, or air. Sulfuric acid may be also produced as a result of sulfur dioxide reacting with other chemicals in the air.
Natural sources
Sulfuric acid occurs naturally in volcanic gasses.
Transport sources
Although sulfuric acid is not found in motor vehicle exhaust, it may be produced by the reaction of sulfur dioxide in the exhaust with other chemicals.
