چکیده

Acid rain is an outcome of air pollution which was first discovered in 1581. Acid rain formation is due to the atmospheric discharge of sulfur and nitrogen oxides which are mainly the outcome of burning the fossil fuels. Acid rain can cause environmental disruptions like; damaging the forests, lakes, groundwater, and soils. The damage caused by acid rain depends on the level of acid deposition and the natural sensitivity of soils and water bodies. There are set of solutions suggested which some are used for prevention of acid rain (such as international protocols issued to reduce emissions and using alternative ways to produce energy) and others for recovery of affected areas (such as liming process used to neutralize acidic lakes and streams).
