Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions ( low pH ).

Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides, which react with the water molecules in the atmosphere to produce acids.

Acid rain has been shown to have adverse impacts on forests, freshwaters and soils, killing insect and aquatic life-forms as well as causing damage to buildings and having impacts on human health.

Acid rain has eliminated insect life and some fish species, including the brook trout in some lakes, streams, and creeks in geographically sensitive areas, such as the Adirondack Mountains of the United States.

Acid rain does not directly affect human health.

Acid rain can also damage buildings and historic monuments and statues, especially those made of rocks, such as limestone and marble, that contain large amounts of calcium carbonate.

Acid rain also increases the corrosion rate of metals, in particular iron, steel, copper and bronze.

The overall goal of the Acid Rain Program established by the Act is to achieve significant environmental and public health benefits through reductions in emissions of sulfur dioxide ( SO < sub > 2 </ sub >) and nitrogen oxides ( NO < sub > x </ sub >), the primary causes of acid rain.
