Environmental Health Center Ozone Fact Sheet What Is Ozone? Ozone is a colorless gas that is a variety of oxygen. Oxygen consists of two oxygen atoms; while ozone consists of three. Ground-level ozone is one of the main components of smog, which is formed by the interaction of hydrocarbons (unburned or evaporated gasoline) and nitrogen oxides in the presence of sunlight. Where Is It Found? Stratospheric ozone (in the upper atmosphere) is known as the ozone layer and protects our health by shielding us from the sun's damaging ultraviolet rays. However, ground-level, ozone (tropospheric ozone) is a pollutant with highly toxic effects. It is a health hazard causing damage to human health, the environment, crops, and a wide range of natural and artificial materials. What Are the Health Effects of Ground-Level Ozone? Ozone that is close to the ground can cause eye irritation; headaches; coughing; impaired lung function; and eye, nose, and throat irritation. Asthmatics and children are most at risk. The chance of experiencing adverse health effects from elevated ozone levels increases during heavy exercise or outdoor activity. Ground-level ozone can also damage trees, plants, and reduce visibility. What Causes Ground-Level Ozone?

Sunburn and Sunlight Very simply, sunburn and UV light can damage your skin, and this damage can lead to skin cancer. There are of course other determining factors, including your heredity and the environment you live in. However, both the total amount of sun received over the years, and overexposure resulting in sunburn can cause skin cancer. Most people receive 80% of their lifetime exposure to the sun by 18 years of age. The message to parents from this is to

Wood heaters See also: State of the environment Water Land Waste ... Air pollutants Ozone Environmental and health effects of ozone Measurement of ozone Ozone is an indicator of photochemical smog. Ozone is a colourless, highly reactive gas with a distinctive odour. It is formed naturally by electrical discharge (lightning) and in the upper atmosphere at altitudes of between 15 to 35km. Stratospheric ozone protects the Earth from harmful ultraviolet radiation from the sun. However at ground level, elevated levels of ozone are produced by photochemical reactions involving other air pollutants. Given sunlight and suitable meteorological conditions, nitrogen oxides and volatile organic compounds can react to form photochemical oxidants (also known as photochemical smog) of which ozone is the principal component. The production of photochemical oxidants usually occurs over several hours which means that the highest concentrations of ozone normally occur on summer afternoons, in areas downwind of major sources of ozone precursors.

Houston Environmental Foresight Seeking Environmental Improvement Ozone Layer Thinning The layer of ozone in the stratosphere, a layer far above the earth's surface, is critical to life on earth because it blocks out ultraviolet rays. Human activities have reduced ozone concentrations in the upper atmosphere at some times and in some places around the world. A thinner ozone layer is likely to cause a noticeable increase in skin cancer, eye problems, and other diseases. The "ozone hole" is probably the best known result of the thinning of the ozone layer. Scientists are certain that man-made chemicals (chlorofluoro-carbons, or CFCs) have reduced the amount of ozone in the upper atmosphere. The most dramatic effects have occurred over Antarctica, where levels of ozone drop sharply every September forming a "hole" in the ozone layer. The Foresight Committee ranked ozone thinning in the category of least risk because serious effects are not expected in the Houston area. Two findings influenced this ranking. First, ozone layer thinning effects in the United States are strongest in the northwest; there may be effects over Houston, but so far satellite data suggests changes are negligible.

It occurs from natural processes and human activities, and it is one component of photochemical smog. Ozone may have very different effects depending on its location in the atmosphere. Ozone in the upper atmosphere, 10 to 30 miles above the Earth's surface, is often referred to as "good ozone." This layer of ozone provides protection from the sun’s ultraviolet rays that can damage our skin and cause skin cancer. For more information about the depletion of good ozone, see the

119. The Mystery Of The Missing Gases CFC, and most of it derives from natural environmental processes. Methyl chloride supplies chlorine atoms to the stratosphere, where they can deplete ozone. http://www.nature.com/nsu/000120/000120-9.html

updated at midnight GMT search nature science update advanced search The mystery of the missing gases Vast quantities of an ozone-destroying gas have been found seeping unsuspected from warm coastal environments, reports Philip Ball. 20 January 2000 PHILIP BALL The thinning of the protective layer of ozone-rich air high in the Earth's atmosphere is caused primarily by chlorine-containing gases released into the air by human activities. But the most abundant chlorine-containing substance in the atmosphere, a compound called methyl chloride, comes mostly from natural sources. However, there is a big hole in our knowledge of what these sources are. Now three papers in Nature promise to plug this gap. The ozone layer in the stratosphere helps to shield the surface of the planet from the harmful ultraviolet rays in sunlight. As became clear in the 1980s, chlorine-containing compounds such as the chlorofluorocarbons (CFCs) used as aerosol propellants, solvents and refrigerants have eroded this protective coating, especially in Antarctica. Although CFCs are now being rapidly phased out, they last for a long time in the atmosphere and it will be many years before their effects on ozone are eliminated. In the meantime, researchers need to be able to predict changes and trends in the amounts of chlorine-containing compounds in the atmosphere so as to anticipate their consequences for the ozone layer.
