What is Acid Rain?
Acid rain is rain, snow, fog or dry particles and gases that is polluted by acid in the atmosphere and damages the environment. Acid rain damages surface waters (lakes, rivers, streams) and the fish and animals living in them, other living things like plants, forests and soils, materials and structures (marble, limestone, sandstone, metals, paints, textiles, ceramic, leather, rubber), and especially human health through the atmosphere as we breathe or through the soil where the food we eat was grown from.
Acid rain is formed when sulfur dioxide and nitrogen oxides react with water, oxygen and other chemicals in the atmosphere to form strong acidic compunds such as nitric and sulfuric acids. Sulfur dioxide and nitrogen oxides, once released into the atmosphere, can be carried over long distances (can be hundred of miles), then will return to the earth as acidic rain, snow, fog or dust.
