(Sulfur Dioxide) A strong smelling, colorless gas that is formed by the combustion of fossil fuels. Power plants, which may use coal or oil high in sulfur content, can be major sources of SO2.
Acid Rain Acids form when certain atmospheric gases (primarily carbon dioxide, sulfur dioxide, and nitrogen oxides) come in contact with water in the atmosphere or on the ground and are chemically converted to acidic substances.
The most important trace gases contributing to the greenhouse effect are water vapor, carbon dioxide, ozone, methane, ammonia, nitric acid, nitrous oxide, ethylene, sulfur dioxide, nitric oxide, dichlorofluoromethane or Freon 12, ...
Acid rain, caused by industrial emission of sulfur dioxide and nitrogen oxides into the atmosphere, adversely effects freshwater lakes, vegetation, and structures.
Anthropogenic pollutants reduce air quality and visibility.
acid rain: rain that has become acidic after contact with certain atmospheric gases (primarily sulfur dioxide, carbon dioxide, and nitrogen oxides).
afforestation: process of establishing a forest.
5 or less, due to the dissolution of acidic gases such as carbon dioxide and sulfur dioxide. In polluted continental areas the pH can drop to as low as 3.
