science of ozone :: essays research papers fc

THE SCIENCE OF OZONEOzone, though similar to atomic number 8 chemically, is composed of tercet molecules of atomic number 8 and is usually blue in color with a very unanimous odor. The atmosphere contains slight ozone than the common oxygen. While out of every go jillion air molecules, there exist rough two million molecules of normal oxygen and only three molecules of ozone. Most of these ozone molecules are typically concentrated in the Stratosphere, the atmospheric layer that runs roughly from ten kms to about fifty kms in altitude. Even though the amount of ozone in the atmosphere is small, it plays a vital role in the atmosphere. The ozone layer protects the Earth and everything on it by absorbing the suns UV radiation. When the ozone is not at an atmospheric level and is at ground level, ozone proves to have toxic effects.Inhaling somewhat low amounts of ozone can result in signs and symptoms such as coughing, congestion, wheezing, precipitance of breath, and chest pain in otherwise healthy people. People with already existing asthma, bronchitis, heart disease, and emphysema may find their conditions worsen tour inhaling ozone. Breathing ozone may similarly increase the risk of getting trusted lung diseases. People can recover from short-term exposure to low levels of ozone. However, public discussion high levels of ozone or breathing low levels of ozone over a hanker period of time may have more damaging and longer-lasting effects. Ozone has also been found to have positive effects on people. It has proven to be a very purifying substance. Doctors are now aware that it has three powerful properties 1. It stimulates the immune systems through production of natural cancer-killing proteins called cytokines. 2. It improves oxygenation (delivery of oxygen to esurient tissues) and metabolism.3. It is a powerful antibiotic when applied locally.Ozone is made naturally in the atmosphere or artificially by using high voltages or unseeable rays. Ozone and Oxygen work together efficiently to prevent the ultraviolet radiations reaching the earths surface. The ultraviolet radiations with shorter wavelengths, such as wavelengths less than 242 nm, have sufficient energy to break the O-O covalent bonds in the oxygen molecules and are thereby utilise up by the oxygen molecules. 242 nmO2 (g) 2O (g)Similarly, ultraviolet radiations with higher wavelengths, for example more than 242 nm to 320 nm, are used up in breaking the bonds between the oxygen atoms in an Ozone molecule.242-320 nm
