Description

Acid deposition primarily results from the transformation of air pollutants such as sulfur dioxide and nitrogen oxides into secondary pollutants such as sulfuric acid, ammonium nitrate and nitric acid. Acidic particles and vapors can be deposited on the earth’s surface as acid precipitation (wet deposition) or via particles such as fly ash, sulfates, nitrates, and gases (dry deposition).
