A strong smelling, pale blue, reactive toxic chemical gas consisting of three oxygen atoms. It is a product of the photochemical process involving the sun's energy and ozone precursors, such as hydrocarbons and oxides of nitrogen. 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 is associated with numerous adverse health effects. It is a major component of smog.
Ozone (O3) is a form of oxygen. It is a colourless gas that has a very pungent odour. It exists naturally at low concentrations in the stratosphere where it absorbs ultraviolet radiation. In the troposphere it exists naturally at extremely low concentrations. But these concentrations increase when sunlight acts on various gases, coming mainly from vehicle exhausts, and ozone then becomes a pollutant in the troposphere. Ozone is a highly corrosive gas and is poisonous to most organisms. At concentrations as low as 0.00001 per cent (or 10 parts per hundred million) it can irritate the membranes lining the nose, throat and airways and can trigger or exacerbate asthma attacks.
Three-atom oxygen compound (O3) found in two layers of the Earth's atmosphere. One layer of beneficial ozone occurs at 7 to 18 miles above the surface and shields the Earth from ultraviolet light. Several holes in this protective layer have been documented by scientists. Ozone also concentrates at the surface as a result of reactions between byproducts of fossil fuel combustion and sunlight, having harmful health effects.

(O3). Ozone consists of three atoms of oxygen bonded together in contrast to normal atmospheric oxygen which consists of two atoms of oxygen. Ozone is an important greenhouse gas found in both the stratosphere (about 90% of the total atmospheric loading) and the troposphere (about 10%). Ozone has other effects beyond acting as a greenhouse gas. In the stratosphere, ozone provides a protective layer shielding the Earth from ultraviolet radiation and subsequent harmful health effect on humans and the environment. In the troposphere, oxygen molecules in ozone combine with other chemicals and gases (oxidization) to cause smog.

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.

Ozone is the product of chemical reactions that occur in the atmosphere on hot days (usually temperatures over 90 degrees Fahrenheit) in the presence of sunlight. The chemical reactants that produce ozone under these conditions are nitrogen oxides (nitric oxide and nitrogen dioxide, together referred to as NOx) and volatile organic compounds (VOCs). Sources of VOCs include gasoline, paints, inks, cleaning solutions, waxes, polishes, aerosol sprays and many other products that evaporate readily. As a result of atmospheric processes that can transport NOx andVOCs downwind, ozone formation can occur in areas removed from the sources of the emissions.

Ozone is a unique emission because it is not directly produced by human sources. Instead, it is created as a result of chemical reactions between human-produced emissions and other gases in the atmosphere. Ozone is also unique because it is considered beneficial in some places and detrimental in others. When ozone is in the earth's upper atmosphere it is considered good because it protects the earth from the sun's radiation.

Ozone in the troposphere, near Earth's surface, on the other hand, is a harmful pollutant resulting from the interaction of anthropogenic emissions of nitrogen oxides and volatile organic compounds and sunlight.
03 instead of 02. This 3-atom molecule is an even more active oxidizing agent than its more common 2-atom relative. 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.

Molecule consisting of 3 atoms of oxygen. Ozone is a colorless gas at room temperature and is a highly corrosive substance and common pollutant. Ozone in the upper atmosphere helps reduce the amount of damaging UV radiation from the sun. Ozone in the lower atmosphere (the air we breathe) can be harmful to the respiratory system and can be harmful to health.
Ozone consists of three atoms of oxygen bonded together in contrast to normal atmospheric oxygen which consists of two atoms of oxygen. Ozone is formed in the atmosphere and is extremely reactive and thus has a short lifetime. In the stratosphere ozone is both an effective greenhouse gas (absorber of infra-red radiation) and a filter for solar ultra-violet radiation. Ozone in the troposphere can be dangerous since it is toxic to human beings and living matter. Elevated levels of ozone in the troposphere exist in some areas, especially large cities as a result of photolytic reactions of hydrocarbons and oxides of nitrogen, released from vehicle emissions and power stations.

In the forest industry phosphorus mainly originates in wood raw material.
Ozone is a colorless, odorless gas created at ground level by a chemical reaction between NOx and hyrocarbons in the presence of sunlight. Depending on its location, ozone can be "good" or "bad." Atmospheric, or "good," ozone exists in the earth's upper atmosphere, forming a protective layer that shields us from the sun's harmful rays. Ground-level, or "bad," ozone is created by pollution, and can trigger a variety of health problems. Ground-level ozone peaks during the summer months, particularly when the days are hot and dry.

Ozone consists of three oxygen atoms stuck together (O3) 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.

Ozone is a special type of oxygen molecule caused by bonding a third oxygen atom to an oxygen pair. This is most often accomplished using ultraviolet light. Ozone (O3) is highly unstable and reacts with air borne particles by launching the extra oxygen at anything near it. The oxygen atom reacts with the air borne particle, causing a tiny explosion and the destruction of the particle. Ozone purifiers are highly effective against both dust and microscopic organisms, but can be unhealthy if a person is exposed to large quantities.

Ozone, the triatomic form of oxygen (O3), is a gaseous atmospheric constituent. In the troposphere, it is created both naturally and by photochemical reactions involving gases resulting from human activities (photochemical smog). In high concentrations, tropospheric ozone can be harmful to a wide range of living organisms. Tropospheric ozone acts as a greenhouse gas. In the stratosphere, ozone is created by the interaction between solar ultraviolet radiation and molecular oxygen (O2). Stratospheric ozone plays a decisive role in the stratospheric radiative balance. Depletion of stratospheric ozone, due to chemical reactions that may be enhanced by climate change, results in an increased ground-level flux of ultraviolet radiation.
A form of oxygen, O3, found in the atmosphere in minute quantities, especially after a thunderstorm. A powerful oxidizing agent, and thus biologically corrosive. In the upper atmosphere, it absorbs ultraviolet rays, thereby preventing them from reaching the surface of the earth. It is used for bleaching, sterilizing water, and more.
