O-Zone is a triatomic molecule which is comprised of three oxgyen atoms. O-zone found in lower parts of the atmosphere is considered a pollutant and can be extrememly hazardous, causing damage to very sensitive plants. O3 is also known to have hamrful effects on the respristory systems of animals. Found in uppher parts of the atmospher (mainly the stratosphere), it protects the earth from dangerous electromagnetic radiation that is created by the sun. O-zone is also used in many different industrial and consumer forms.


History of O-Zone

The first detection of o-zone may have occured sensorially by a dutch chemist by the name of Van Marum, who detected a strange smell while conducting an experiment using an electrifier. It wasnt until scientist Christian Friedrich Schonbein conducted a similar experiment that 03 would be indentified appropriatley. In scientific notes submited to the Univeristy of Munich, Schonbein stated that his expirement had produced a gas with a smell characteristically indentical to the smell identified by Marum. Schonbein named this gas o-zone, derived from the greek word ozein, meaning scent. Schonbein is usally accredited with the discovery of o-zone and is noted as the first person to study its affects on organic matter. After the 1840's many experiments were conducted in regards to o-zones discenfective mechanisms. These studies would lead german scientist Von Siemens in Berlin, to create the first device which function was to create O3. This was later followed by his book describing O-zones purifying affects on water.
Applications of O-Zone
O-zone is most commonly known for its function in the stratosphere. The O-zone layer acts as a shield, protecting us from harmful radiation that is produced by the sun. Because of various types of air pollution including CFC's and other carbon emissions, scientists have discovered that certain parts of this layer have began to develop certain holes. The ultimate effects of these holes is yet to be determined, but disenegration of the o-zone layer may have very radical effects on the planet and its climate. Apart from O3 in the stratosphere, O-zone has many other functions. In many countries O-zone is used the main element in water purifiction facilities in place of chlorine. It is also used as a disenfectant in many hospitals and manufacturing facilties. O-zone emmiting devices have been sold across the globe as air purififiers while o-zone can also be seen used agricultularly in many instances to destroy certain molds and bacterias.
