The 2000 ozone season ended officially at midnight last night.
Ozone is an odorless, colorless gas that irritates the lungs and interferes with breathing.
The effects of ozone are most profound on children and the elderly, as well as those with breathing problems such as asthma or emphysema. If accepted by the EPA, the EIP would take the place of a non-attainment designation. Ozone is a secondary pollutant, formed by the chemical interaction of nitrogen oxides and volatile organic compounds in sunlight. Meteorological conditions in San Antonio, especially long periods of very hot weather and wind patterns, influence ozone formation profoundly. Citizens can help reduce ozone levels in breathing air by getting regular tune-ups for their cars and reducing the number of miles they drive by carpooling, using mass transit, bicycling, or walking in their daily commute.
