Ozone Program

Ozone is a colorless gas that can be found throughout the earth's atmosphere. In the upper atmosphere, ozone exists naturally where it shields the earth from the sun's ultraviolet rays. At ground-level, however, ozone is formed as a result of chemical reactions caused by the presence of nitrogen oxides (NOx) and volatile organic compounds (VOCs). These compounds react with oxygen in the air in the presence of heat and strong sunlight to produce ground-level ozone, the primary ingredient of summertime smog. Ground-level ozone is one of the six criteria air pollutants (see "Related Programs") identified by the US Environmental Protection Agency under the federal Clean Air Act. more…
