- Ozone - Wikipedia
Ozone is formed from dioxygen by the action of ultraviolet (UV) light and electrical discharges within the Earth's atmosphere It is present in very low concentrations throughout the atmosphere, with its highest concentration high in the ozone layer of the stratosphere, which absorbs most of the Sun 's ultraviolet (UV) radiation
- What is Ozone? - US EPA
Stratospheric ozone is formed naturally through the interaction of solar ultraviolet (UV) radiation with molecular oxygen (O2) The "ozone layer," approximately 6 through 30 miles above the Earth's surface, reduces the amount of harmful UV radiation reaching the Earth's surface
- Ozone - American Lung Association
Ozone (also called smog) is one of the most dangerous and widespread pollutants in the U S It may be hard to imagine that pollution could be invisible, but ozone begins that way As ozone concentrates and mixes with other pollutants, we often call it by its older, more common name—smog
- Ozone pollution - Washington State Department of Ecology
Ozone high in the Earth's atmosphere protects us from the sun's harmful radiation But at ground level, ozone is an air pollutant that harms people and plants Ground-level ozone forms when nitrogen oxides and volatile organic compounds react with each other in sunlight and hot temperatures
- Ozone | Definition, Properties, Air Pollution, Importance, Structure . . .
Ozone is an irritating pale blue gas that is explosive and toxic, even at low concentrations It occurs naturally in small amounts in Earth’s stratosphere, where it absorbs solar ultraviolet radiation, which otherwise could cause severe damage to living organisms on Earth’s surface
- Q1 What is ozone, how is it formed, and where is it in the atmosphere?
The word ozone is derived from the Greek word óζειν (ozein), meaning “to smell ” Ozone has a pungent odor that allows it to be detected even at very low amounts Ozone reacts rapidly with many chemical compounds and is explosive in concentrated amounts
- Ozone - New World Encyclopedia
Ozone (molecular formula O 3) is a minor constituent of the Earth's atmosphere, but its effects are highly significant It is chemically very reactive and is involved in reactions that drive many of the chemical changes that occur in the atmosphere by day and by night

The Montreal Protocol on Substances that Deplete the Ozone Layer is a global agreement to protect the Earth’s ozone layer by phasing out the chemicals that deplete it
