Rain near industrial areas commonly contains high contents of sulfate, nitrate, and carbon dioxide CO 2 largely derived from the burning of coal and oil. There are two main processes leading to the conversion of sulfur dioxide SO 2 to sulfuric acid H 2 SO 4. These are reactions with hydroxyl radicals —OH and with hydrogen peroxide H 2 O 2 in the atmosphere:.
These reactions are responsible for the acid rain conditions that occurred in the northeastern United States , southeastern Canada , and western Europe during the second half of the 20th century see below Acid rain. The high sulfate values of the rain in the northeastern United States reflect the acid precipitation conditions of this region.
