Each year industrially developed countries generate billions of tons of
pollutants. The level is usually given in terms of atmospheric concentrations

molecules per million air molecules. Many come from directly identifiable
sources; sulfur dioxide, for example, comes from electric power plants burning
coal or oil. Others are formed through the action of sunlight on previously
emitted reactive materials. For example, ozone, a dangerous pollutant in smog,
is produced by the interaction of hydrocarbons and nitrogen oxides under the
