acid rain

the precipitation of moisture, as rain, with high acidity caused by release into the atmosphere of pollutants from industry, motor vehicle exhaust, and other sources. Acid precipitation with a pH of 5.6 or lower is blamed by various authorities for numerous human health problems, fish kills, and the destruction of timber. Also called acid precipitation, acid snow.See also acid dust,acid flush,and acid mist.
Precipitation laced with pollution, produced predominantly by power plants that burn coal of variable purity, generating SO2 and NO2, lowering the pH of precipitation

acid rain

any rain that contains pollutants such as dissolved sulphur compounds, and as a result adversely affects plant and animal life on precipitation. The pollutants are released into the atmosphere by the burning of fossil fuels such as coal or oil.

acid rain

rain which contains materials, sulfates and oxidation products of nitrogen and sulfur particularly, produced by combustion of coal and oil in industrial processes and by motor vehicles; lowers the pH of water bodies; see acid waters; credited with local decline of fish culture.
