- Ozone or tri-oxygen (O 3) is mostly prominent in the earths atmosphere (20-50 Km above the surface of the earth). It is produced when oxygen molecules (O 2) dissociate into their constituent atoms under the influence of UV-C radiation (below 240 nm) and then combine with O 2 molecules to form ozone. Ozone can also be formed in the lower atmosphere from nitrogen oxides and other pollutants by photochemical reactions.

- Stratospheric ozone is formed naturally by chemical reactions involving solar ultraviolet radiation (sunlight) and oxygen molecules, which make up 21% of the atmosphere. In the first step, solar ultraviolet radiation breaks apart one oxygen molecule (O 2) to produce two oxygen atoms (2 O) (see Figure Q2-1).

Ozone Pollution Ozone Pollution Ground level or bad ozone is not emitted directly into the air, but is created by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC) in the presence of sunlight.

Ozone Low level ozone (or tropospheric ozone) is an atmospheric pollutant. It is not emitted directly by car engines or by industrial operations, but formed by the reaction of sunlight on air containing hydrocarbons and nitrogen oxides that react to form ozone directly at the source of the pollution or many kilometers down wind.

Problems with Ozone Generators and Ionizers that Produce Ozone Conclusions. 1  Whether in its pure form or mixed with other chemicals, ozone can be harmful to health. When inhaled, ozone can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and lung irritation. Animal studies suggest that long term exposure to ozone may lead to permanent scarring of lung tissue, loss of lung function and reduced lung elasticity. It may also worsen chronic respiratory diseases such as asthma and COPD. Machines that generate ozone should never be used around the ill, infirm, young or elderly.

Ambient (outdoor) air quality and health Excessive ozone in the air can have a marked effect on human health. It can cause breathing problems, trigger asthma, reduce lung function and cause lung diseases. In Europe it is currently one of the air pollutants of most concern.

- Ozone forms readily in the stratosphere as incoming ultraviolet radiation breaks molecular oxygen (two atoms) into atomic oxygen (a single atom). In that process, oxygen absorbs much of the ultraviolet radiation and prevents it from reaching the Earth’s surface where we live.In the language of a simplified chemical formula, When an electrically excited free oxygen atom encounters an oxygen molecule, they may bond to form ozone.Destruction of ozone in the stratosphere takes place as quickly as formation of ozone, because the chemical is so reactive. Sunlight can readily split ozone into an oxygen molecule and an individual oxygen atom.zone forms readily in the stratosphere as incoming ultraviolet radiation breaks molecular oxygen (two atoms) into atomic oxygen (a single atom).

The Environment Ozone is a gas made up of molecules that are formed by three oxygen atoms. Its molecule formula is O3. Ozone is formed when the sunlight hits oxygen molecules (O2) and breaks them up into individual atoms. These individual atoms then join up with O2 molecules and make O3, or ozone.

Ozone in the Troposphere Ozone is released naturally in the troposphere by plants and soil. These are such small amounts that they are not harmful to the health of humans, animals or the environment. Ozone that increases because of certain human activities does become a problem at ground level and this is what we think of as 'bad' ozone.ou may have heard of the ozone hole problem-that is a lack of ozone in the stratosphere (the 2nd layer of the Earth's atomsphere). But ozone is also found in the troposphere, the first layer of the Earth s atmosphere. In the troposphere, ozone is NOT wanted!

The Effects What are the effects of air pollution from ozone? Approximately one out of every three people in the United States is susceptible to ozone-related health problems, including shortness of breath, coughing, wheezing, headaches, nausea, and throat and lung irritation.

- Concentrations of stratospheric ozone represent a balance, established over eons, between creative and destructive forces and this balance, or dynamic equilibrium, has been changed by human activity. Ozone is formed in the earth's stratosphere and is critical to life on earth as we know it. There is compelling scientific evidence that ozone is destroyed in the stratosphere and that some human-released chemicals are speeding up the breakdown of ozone in the atmosphere. CFCs, a human-developed compound, are particularly destructive to the breakdown of ozone in the atmosphere.

- Atomic oxygen (O) is formed when ultraviolet sunlight reacts with ozone and oxygen molecules. Cycle 1 is most important in the stratosphere at tropical and middle latitudes, where ultraviolet sunlight is most intense. Significant destruction of ozone occurs in polar regions because ClO abundances reach large values.hese compounds are broken down by the ultraviolet radiation in the stratosphere. Byproducts of the breakdown of these chemicals form radicals such as nitrogen dioxide (NO2) and chlorine monoxide (ClO) that play an active role in ozone destruction.

Chlorofluorocarbon Ultraviolet radiation in the stratosphere causes the CFC molecules to dissociate, producing chlorine atoms and radicals (i.e., chlorodifluoromethyl radical; free radicals are species that contain one or more unpaired electrons).

The Importance of the Ozone With less ozone in the atmosphere, more ultraviolet radiation strikes Earth, causing more skin cancer, eye damage, and possible harm to crops. The main causes of ozone depletion are chlorofluorocarbons (CFC's), such as coolants, aerosols, and fire extinguishers. When CFC's are released, they rise into the ozone layer.

Oxygen Ozone, along with reactive forms of oxygen such as superoxide, singlet oxygen, hydrogen peroxide, and hypochlorite ions, is naturally produced by white blood cells and other biological systems (such as the roots of marigolds) as a means of destroying foreign bodies. Ozone reacts directly with organic double bonds.

Ozone Depletion Specifically, breathing ozone can: 1  Irritate the respiratory system and cause coughing, throat irritation and uncomfortable sensations in the chest. 2  Reduce lung function, leading to more rapid and shallow breathing that may limit a person's ability to engage in vigorous activities.

- The ozone formation-destruction process in the stratosphere occurs rapidly and constantly, maintaining an ozone layer. In the troposphere near the Earth’s surface, ozone forms through the splitting of molecules by sunlight as it does in the stratosphere.However in the troposphere, nitrogen dioxide, not molecular oxygen, provides the primary source of the oxygen atoms required for ozone formation.he process described above results in no net gain in ozone. Concentrations occur in higher amounts in the troposphere than these reactions alone account for. In the 1950s, chemists discovered that two additional chemical constitutents of the troposphere contribute to ozone formation.

Ozone layer The ozone molecule is unstable (although, in the stratosphere, long-lived) and when ultraviolet light hits ozone it splits into a molecule of O2 and an individual atom of oxygen, a continuing process called the ozone-oxygen cycle.

Ozone Ground-level ozone, commonly known as “smog,” is the major summertime cause of poor air quality in the Bay Area. The Spare the Air Every Day program was created to reduce summertime ozone pollution. Ozone is essentially an unstable molecule made up of three oxygen atoms. It is created in the lower atmosphere by a combination of pollutants called reactive organic compounds and oxides of nitrogen that get “cooked” by the sun’s ultraviolet rays in a photochemical reaction.

In the first step, solar ultraviolet radiation breaks apart one oxygen molecule (O2) to produce two oxygen atoms (2 O) (see Figure Q2-1).zone abundance. Ozone molecules have a low relative abundance in the atmosphere. In the stratosphere near the peak concentration of the ozone layer, there are typically a few thousand ozone molecules for every billion air molecules (1 billion = 1,000 million).
