What Is Acid Rain?
Likens, Gene E.
Science and Children, v42 n3 p52 Nov-Dec 2004
Acid rain is the collective term for any type of acidified precipitation: rain, snow, sleet, and hail, as well as the presence of acidifying gases, particles, cloud water, and fog in the atmosphere. The increased acidity, primarily from sulfuric and nitric acids, is generated as a by-product of the combustion of fossil fuels such as coal and oil. Now, long-term data collected from the Hubbard Brook Experimental Forest are available to provide a clear relationship among sulfur dioxide emissions and concentrations of acid forming sulfate in atmospheric deposition and in surface waters.
