Definition of ozone in English: ozonenoun ˈəʊzəʊnˈoʊˌzoʊn mass noun1A colourless unstable toxic gas with a pungent odour and powerful oxidizing properties, formed from oxygen by electrical discharges or ultraviolet light. It differs from normal oxygen (O₂) in having three atoms in its molecule (O₃). 臭氧(O3) Example sentencesExamples - Photo chemical smog is caused by the chemical interacting with the sunlight creating ozone and other toxic substances.
- The District's urban forest improves air quality by removing nitrogen dioxide, sulfur dioxide, carbon monoxide, ozone, and particulate matter.
- A form of oxygen, ozone protects life on Earth from the harmful effects of ultraviolet radiation.
- Already used to control bacteria in some pools and aquariums, ozone gas causes oxidizing reactions that damage tissue.
- Your lungs may be exposed to pollutants such as ozone, carbon monoxide, sulfur dioxide, and sulfuric acid.
- The sunlight splits the chlorine into highly reactive ions that break ozone down into normal oxygen molecules.
- Nitrogen Oxides, primarily from automobile exhaust, ramp up ozone production to toxic levels.
- Water vapour, carbon dioxide, ozone, methane, nitrous oxide, and the chlorofluorocarbons are known as Greenhouse Gases.
- Even though it's made of only three little molecules of oxygen, ozone can be a pretty big topic.
- Carbon monoxide is not only a hazardous air pollutant itself, it is also a chemical compound that produces ozone, a greenhouse gas that is a human health hazard.
- The city is constantly bathed in a visible haze of harmful pollutants: Sulphur dioxide, nitrogen oxides, ozone and smoke.
- Although CO2 is by far the most well known green house gas, we humans also produce others in the form of methane, CFC's, ozone and nitrous oxide.
- The mean temperature of the earth's surface is about 33°C warmer than it would be in the absence of natural greenhouse gases such as water vapour, carbon dioxide, methane, nitrous oxide, and ozone.
- Recent experiments have begun identifying oxidizing gases, such as ozone and molecules containing the halogens bromine and chlorine, as triggers for that mercury fallout.
- Public water systems treat water with chlorine, ultraviolet light or ozone to kill E. coli.
- Adding that third oxygen atom makes ozone a very pushy and highly obnoxious little molecule.
- Automotive emissions are a major source of ozone and carbon monoxide pollution.
- The four usual agents of deterioration in the air apart from oxygen and water are sulphur dioxide, hydrogen sulphide, ozone and nitrogen dioxide.
- For example, plant tissues challenged with acutely toxic levels of ozone rapidly produce a burst of ethylene.
- Biofuels, such as ethanol, can reduce carbon dioxide, ozone formation and carbon monoxide by as much as 90 percent.
- 1.1
short for ozone layer Example sentencesExamples - Part I of The Ozone Layer relates the history of our understanding of stratospheric ozone.
- The Institute Nacional de Meteorologia provided the radiometric, columnar ozone and meteorological information for the three stations used in this study.
- The Sun is a strong UV emitter but only near UV reaches the surface of the Earth because the ozone in the atmosphere absorbs all wavelengths below 290 nm.
- Also, the presence of stratospheric ozone sandwiched between the satellite and the troposphere makes seeing tropospheric ozone very difficult.
- Recent changes in surface UV solar radiation and stratospheric ozone have also been reported at a high Arctic site, although it is still too early to make trend estimates.
- Acid rain, stratospheric ozone depletion, and climate change are major regional or global problems arising from atmospheric pollution.
- Researchers analyzed data from several sources, and found a strong correlation between cosmic ray intensity and ozone depletion.
- Between 1980 and 2000, the protective ozone in the stratosphere, about 10 to 30 miles high, decreased 3 percent.
- The exhaust gases that these cars produce are very harmful to the environment, causing a variety of ecological problems such as ozone depletion and global warming.
- ‘No one predicted the dramatic loss of ozone in the upper stratosphere of the northern hemisphere in the spring of 2004,’ she said.
- Tropospheric ozone can permanently damage people's lungs and prohibit plants from producing and storing food.
- No one disputes that stratospheric ozone recovery is one of the environmental movement's great success stories.
- High in the atmosphere this is not a problem as ozone blocks the harmful rays from the sun.
- The stratosphere is rich in ozone, a greenhouse gas that filters out dangerous solar particles such as ultraviolet light.
- This story is too far fetched, because a hole in the ozone in Antartica would generate so much heat, that Antartica would be a tropical forest, or a fiery wasteland!
- Research published in 1994 suggests that increased ultraviolet radiation caused by stratospheric ozone depletion may be killing frog eggs.
- The ozone hole still contains ozone, just at extremely low levels compared with the surrounding stratosphere.
- So, as we learn more about stratospheric ozone and climate change, what were once two separate problems have become more and more entwined.
- Standard vertical profiles of pressure, temperature, relative humidity and ozone density are selected, according to the U.S. Standard Atmosphere.
- In the upper atmosphere, or the stratosphere, ozone is very good, as it acts as a shield to protect life on Earth from harmful Ultraviolet sunlight.
2British informal Fresh invigorating air, especially that blowing on to the shore from the sea. 〈非正式〉(尤指海风吹到海滨来的)清新空气 Example sentencesExamples - The rain had taken the city's baseline odor of fear and body fluids and replaced it with fresh, sweet-smelling ozone.
- Because of wind patterns, most ozone blows east to Fountain Hills.
OriginMid 19th century: from German Ozon, from Greek ozein 'to smell'. Today the usual association of ozone is with the ozone layer, a layer in the earth's stratosphere that absorbs most of the harmful ultraviolet radiation reaching the earth from the sun, and which is under threat from atmospheric pollutants. Ozone is a strong-smelling, poisonous form of oxygen whose name goes back to Greek ozein ‘to smell’. It was originally believed to have a tonic effect and to be present in fresh air, especially at the seaside. In Penelope Mortimer's autobiographical About Time (1987) she writes: ‘An important part of our middle-class Englishness was the seaside holiday—no baking on a Mediterranean beach, but lungfuls of ozone, gales, hard sand.’
