A colorless gaseous substance (O/) obtained (as by the silent discharge of electricity in oxygen) as an allotropic form of oxygen, containing three atoms in the molecule. It is a streng oxidizer, and probably exists in the air, though by he ordinary tests it is liable to be confused with certain other substances, as hydrogen dioxide, or certain oxides of nitrogen. It derives its name from its peculiar odor, which resembles that of weak chlorine.
We're looking at Earth science, observing our planet. Also space science, looking at the ozone in the atmosphere around our Earth. Also looking at life science. And on a human level, using ourselves as test subjects. Laurel Clark
When I was a kid, we never heard of smog, ozone depletion, acid rain, green house gasses. Dennis Weaver
The park lies directly downwind from a slew of coal plants. Virtually all of the major contaminants in the local air and water are direct results of coal emissions. Coal produces ozone, which kills trees. Coal produces sulfates, which kill fish. No other park in the country has more ozone or sulfates than Shenandoah National Park. Wil S. Hylton
It's absolutely stupid that we live without an ozone layer. We have men, we've got rockets, we've got saran wrap - fix it! Lewis Black
Despite Arizona's remarkable growth in recent years, we have met the current federal health standards for ozone pollution and the Environmental Protection Agency recently approved our dust control plan. Jane D. Hull
