Definition of ozone in English English dictionary: An allotrope of oxygen (symbol O3) having three atoms in the molecule instead of the usual two; it is a blue gas, generated from oxygen by electrical discharge; it is poisonous and highly reactive, but in the upper atmosphere it protects life on Earth from ultraviolet radiation; (informally but erroneously) Fresh air, especially that breathed at the seaside and smelling of seaweed; A gas which is a variety of oxygen The oxygen gas found in the air consists of two oxygen atoms stuck together; this is molecular oxygen Ozone consists of three oxygen atoms stuck together into an ozone molecule Ozone occurs in nature; it produces the sharp smell you notice near a lightning strike High concentrations of ozone gas are found in a layer of the atmosphere -- the stratosphere -high above the Earth Stratospheric ozone shields the Earth against harmful rays from the sun, particularly ultraviolet B Smog's main component is ozone; this ground-level ozone is a product of reactions among chemicals produced by burning coal, gasoline and other fuels, and chemicals found in products such as solvents, paints, and hair sprays; Ozone is a colourless gas which is a form of oxygen. There is a layer of ozone high above the earth's surface. What they find could provide clues to what might happen worldwide if ozone depletion continues. Pale blue gas (O3) that is irritating, explosive, and toxic. Like ordinary oxygen gas (O2), it contains oxygen atoms, but the bonding of three atoms per molecule gives it distinctive properties. It is formed in electrical discharges and accounts for the distinctive odour of the air after thunderstorms or near electrical equipment. Usually manufactured on the spot by passing an electric discharge through oxygen or air, it is used in water purification, deodorization, bleaching, and various chemical reactions that require a strong oxidizing agent (see oxidation-reduction). Small amounts that occur naturally in the stratospheric ozone layer absorb ultraviolet (UV) radiation that otherwise could severely damage living organisms. Near Earth's surface, ozone contributes to air pollution, ozone produced by auto emissions in the presence of sunlight being a deleterious component of smog, and also accelerates the deterioration of rubber; 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; The tri-atomic allotrope of oxygen; a pale blue gas with a distinctive pungent odour, formula O3 It is a highly reactive oxidising agent and is very poisonous, and is considered a serious pollutant at concentrations much in excess of 125 g/m3 (WHO 1980) It is naturally occurring in the atmosphere It occurs at large concentrations in the upper atmosphere, where it is formed by the action of solar ultraviolet radiation In the troposphere, O3 is mostly formed by photochemical reactions involving hydrocarbons and nitrogen oxides;

Ozone is a triatomic molecule of Oxygen (O3), an element that usually exists as a diatomic molecule (O2) Ozone is formed in the upper atmosphere by the action of ultraviolet light and other forms of dangerous radiation The Ozone Layer is extremely important in screening the Earth's surface from harmful radiation from the sun; Fresh air, especially that breathed at the seaside and smelling of seaweed; An allotrope of oxygen (symbol O{3}) having three atoms in the molecule instead of the usual two; it is a blue gas, generated from oxygen by electrical discharge; it is poisonous and highly reactive, but in the upper atmosphere it protects life on Earth from ultraviolet radiation; Much like cholesterol, there is "good" ozone and "bad" ozone The good ozone (atmospheric) lies in the upper reaches of the atmosphere, helping protect us from ultraviolet radiation from the sun However, when ground level ozone (tropospheric) is in the air we breathe, it's not healthy What we commonly call "smog" is really ozone build-up in the air The use of E-10 Unleaded has been shown to help reduce tropospheric ozone levels; -A molecule composed of three atoms of oxygen and mostly found in the stratosphere Ozone absorbs the most dangerous ultraviolet rays before they can hit the earth, thus protecting life on this planet from its adverse effects; A gas formed when oxygen is ionized by, for example, the action of ultraviolet light or a strong electric field It has the property of blocking the passage of dangerous wavelengths of ultraviolet light Although it is a desirable gas in the stratosphere, it is toxic to living organisms at ground level (see volatile organic compound); (O3) A kind of oxygen that has three atoms per molecule instead of the usual two Ozone is a poisonous gas and an irritant at the earth's surface, capable of damaging lungs and eyes But the ozone layer in the stratosphere shields life on earth from deadly ultraviolet radiation from space; A gas, O3, which is very reactive It is used as a sterilizing agent to kill bacteria and small organisms in the water It is used in an ozone reactor or protein skimmer It is important not to use too much ozone, and to filter ozonated water through carbon before returning it to the tank, as excess ozone can harm fish and other creatures; 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; at the ground level is a form of air pollution that is produced when nitrogen oxides and hydrocarbons react in sunlight It is not to be confused with stratospheric ozone, which is found 9 to 18 miles high in the Earth’s atmosphere and protects people from harmful radiation from the sun Ground-level ozone pollution, or smog, is mainly a problem during hot summer days; O3, a triatomic form of oxygen; a pungent, unstable blue gas that in the upper atmosphere forms a protective layer against excess ultraviolet radiation, and is also an ingredient of photochemical smog in the lower atmosphere; it is used in purification of drinking water and as an oxidizing agent; A harmful form of oxygen that is produced when sunlight creates a reaction between nitrogen oxide and hydrocarbons Next to the earth's surface, ozone is a major component of smog Ozone exists in the upper atmosphere ozone layer (stratospheric ozone) as well as at the Earth's surface in the troposphere (ozone) Ozone in the troposphere causes numerous harmful health effects and is a criteria air pollutant; It derives its name from its peculiar odor, which resembles that of weak chlorine; A form of oxygen (O3), each molecule of which consists of three oxygen atoms Ozone exists in the troposphere (lower part of the atmosphere) above urban areas as a result of photochemical reactions between nitrogen oxides and hydrocarbons (emitted by motor vehicles) in the presence of bright sunlight It acts as a greenhouse gas and at ground level is a pollutant harmful to plants; a molecule containing three atoms of oxygen It is a beneficial component of the upper atmosphere that protects the Earth from harmful ultraviolet radiation from the Sun; Ozone is harmful to both humans and plants at ground level, but is crucial in blocking ultraviolet radiation in the stratosphere; this is the meaning of the commonly used phrases "bad ozone" and "good ozone" In the United States, an ozone exceedance, as defined by the National Ambient Air Quality Standards (NAAQS) occurs when the average hourly concentration is 120 ppb or greater Typical unpolluted surface levels of ozone are around 20 ppb Highest concentrations of ozone are found in the stratosphere, however, where it is very effective at absorbing ultraviolet radiation, itself shown to be harmful to biological systems Depletion of stratospheric ozone by manmade chlorofluorocarbons (CFCs) is a serious global concern due to the potential increase in ultraviolet radiation that may reach the surface of the Earth as a result of stratospheric ozone layer thinning; A form of oxygen that has a pale blue color and a strong smell This gas is formed when an electrical discharge passes through the air It can be poisonous in large quantities The ozone layer high above Earth's surface blocks out some of the harmful rays of the sun; A gaseous molecule that contains three oxygen atoms (O3) Ozone can exist either high in the atmosphere, where it shields the Earth against harmful ultraviolet rays from the sun, or close to the ground, where it is the main component of smog Ground-level ozone is a product of reactions involving hydrocarbons and nitrogen oxides in the presence of sunlight Ozone is a potent irritant that causes lung damage and a variety of respiratory problems; 03 instead of 02 This 3-atom molecule is an even more active oxidizing agent than its more common 2-atom sister At ground level, ozone is a pollutant and in the upper atmosphere it is a solar shield (location, location, location) Touted for its ability to "clean" air in room or household ozone generators, this application actually does more harm than good-ozone's highly reactive nature tends to accelerate the breakdown of synthetic materials in homes such as paints, plastics, and ever-available volatile organic compounds, often with less-than-desirable results All told, we look to protect ozone in the heavens and shun it here at home, inside and out; An almost colorless, gaseous form of oxygen with an odor similar to weak chlorine A relatively unstable compound of three atoms of oxygen, ozone constitutes--on the average--less than one part per million (ppm) of the gases in the atmosphere (peak ozone concentration in the stratosphere can get as high as 10 ppm) Yet ozone in the stratosphere absorbs nearly all of the biologically damaging solar ultraviolet radiation before it reaches the Earth's surface where it can cause skin cancer, cataracts, and immune deficiencies, and can harm crops and aquatic ecosystems See ozone layer; Tri-atomic oxygen that exists in the Earth's atmosphere as a gas Ozone is highest in concentration in the stratosphere (10-50 kilometers above the Earth's surface) where it absorbs the sun's ultraviolet radiation Stratospheric ozone is produced naturally and helps to protect life from the harmful effects of solar ultraviolet radiation Over the last few decades levels of stratospheric ozone have been declining globally, especially in Antarctica Scientists have determined that chlorine molecules released from the decomposition of chlorofluorocarbons are primarily responsible for ozone destruction in the stratosphere It is also abundant near the the Earth's surface in highly polluted urban centers In these areas, it forms as a by product of photochemical smog, and is hazardous to human health; a colorless gas (O3) soluble in alkalis and cold water; a strong oxidizing agent; can be produced by electric discharge in oxygen or by the action of ultraviolet radiation on oxygen in the stratosphere (where it acts as a screen for ultraviolet radiation);

ozone layer: The ozone layer is the part of the Earth's atmosphere that has the most ozone in it. The ozone layer protects living things from the harmful radiation of the sun. A region of the upper atmosphere, between about 15 and 30 kilometers (10 and 20 miles) in altitude, containing a relatively high concentration of ozone that absorbs solar ultraviolet radiation in a wavelength range not screened by other atmospheric components. Also called ozonosphere. a layer of gases in the sky that prevents harmful radiation from the sun from reaching the Earth. or ozonosphere Region in the upper atmosphere, about 6-30 mi (10-50 km) high, with significant concentrations of ozone, formed by the effect of solar ultraviolet (UV) radiation on oxygen and also present in trace quantities elsewhere in earth's atmosphere. Ozone strongly absorbs solar UV radiation, causing atmospheric temperature to climb to about 30°F (0°C) at the top of the layer, and preventing much of this radiation from reaching earth's surface, where it would injure many living things. Chlorofluorocarbons, or CFCs, and some other air pollutants that diffuse into the ozone layer destroy ozone. In the mid-1980s, scientists discovered that a "hole" an area where the ozone is up to 50% thinner than normal develops periodically in the ozone layer above Antarctica. This severe regional depletion, explained as a natural seasonal depletion, appears to have been exacerbated by the effects of CFCs, and may have led to an increase in skin cancer caused by UV exposure. Restrictions on the manufacture and use of CFCs and other ozone-destroying pollutants were imposed in 1978
