Triatomic oxygen, O3, is most commonly known as ozone. It has a resonance structure, and can be drawn in two different ways: O=O- O-O=O It is a bluish, explosive gas at room temperature, and has a boiling point of -119°C. It has a melting point of -193°C, and is a blue liquid. It 's critical temperature and pressure are -12.1°C and 53.8 atm, respectively. It has a pleasant odor in concentrations of less than 2 ppm, and is irritating and injurious in higher concentrations. The density of ozone gas is 2.144 g/L, and the density of ozone as a liquid is 1.614 g/mL. It is extremely unstable, and solutions containing ozone explode upon warming. It is found in varying proportions on Earth, but it is about 0.05 ppm at sea level. Ozone absorbs harmful ultraviolet radiation in the upper atmosphere, and protects humans from skin cancer. But ozone is also the main ingredient of smog, and causes serious health effects and forest and crop damage in the lower atmosphere. Ozone is formed through the chemical reaction of volatile organic compounds and nitrogen dioxide, in the atmosphere, in the presence of sunlight.
This reaction is called a photochemical reaction, because sunlight is required.
The product is known as smog. The notorious brownish color of smog is due to nitrogen dioxide of the mixture. Increased temperature stimulate the reaction, which is why ozone conditions are worse in the summer. It is an oxidant, meaning it takes electrons away from other molecules, and disrupts key structures in cells by starting chain reactions. Ozone is a serious national problem. Half of the largest urban areas in the United States exceed the ozone standards. The worst regions in the US include California and the Texas Gulf coast, and the northeast and the Chicago-
Milwaukee area during the summer. The ozone condition varies from year to year, as the temperature and weather fluctuate. This fluctuation also occurs

    Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth's stratosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone over Earth's polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena, there are also springtime polar tropospheric ozone depletion events. The details of polar ozone…

    Depletion of the Ozone Layer * Function and location of the Ozone Layer The ozone layer is a portion of earth’s atmosphere that contains high levels of ozone. Ozone (O3) is a triatomic molecule consisting of three oxygen atoms. It is an allotrope of oxygen. Ozone is formed when oxygen molecules after absorbing ultra violet photon then converts a single O2 into two atomic oxygen radicals. The atomic radicals then combine with separate O2 molecules to create two O3 molecules. The main function…

    Ozone Depletion: An Introduction Planet Earth has its own natural sunscreen that shields us from the sun's damaging ultraviolet radiation. It's called the ozone layer: a fragile band of gases beginning 15 kilometres above our planet, and reaching up to the 40-kilometre level. Human activities have caused a substantial thinning of this protective covering — not only over the North and South Poles, but right over our heads. Stopping ozone layer depletion is one of the major challenges facing the…

    For that reason the atmosphere and the ozone layer within it are crucial to a stable life on this planet. The ozone layer is in danger, however. It is facing depletion by a toxic man-made substance called chlorofluorocarbons (CFCs). Together the international community is working through treaties and conventions to stop this environmental problem. To understand the problem behind ozone depletion we first must understand what ozone is and how it works. Ozone is a thin protective layer that starts…

    Before I talk about the ozone hole, I would like to talk about what ozone is. Ozone is a gas that is made of three oxygen atoms and it’s found up in the atmosphere (stratosphere layer). These three oxygen atoms are so important to us because they protect us from UV radiation. When UV rays try to come to earth they come across these three oxygen atoms and hits them, converting them into oxygen gas (O2) and one more oxygen (O). That prevents the UV rays from coming to earth. Ozone hole means that it’s…

    radiation. Way up in the part of the atmosphere, called the stratosphere, a layer of gas filters out most of the sun's damaging ultraviolet rays. This layer of gas is called ozone and is located about five miles to 25 miles above the surface of the Earth. (Bright, 1991). Only about one-millionth of our atmosphere is made up of ozone. But it has a tremendously important job. Ozonecan absorb, or soak up, the part of sunlight called ultraviolet radiation. Some ultraviolet radiation still gets through…
