science of ozone :: essays research papers fc

THE SCIENCE OF OZONEOzone, though similar to oxygen chemically, is composed of 3 molecules of oxygen and is usually blue in color with a very(prenominal) strong odor. The atmosphere contains less ozone than the common oxygen. While out of any 10 million air molecules, there exist about twain million molecules of normal oxygen and only three molecules of ozone. Most of these ozone molecules argon 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 world and everything on it by absorbing the suns UV radiation. When the ozone is non at an atmospheric level and is at ground level, ozone proves to have noxious effects.Inhaling fairly secondary amounts of ozone can result in signs and symptoms such as coughing, congestion, wheezing, shortness of breath, and chest pain in oth erwise healthy people. citizenry with already existing asthma, bronchitis, heart disease, and emphysema may find their conditions wane while inhaling ozone. Breathing ozone may also increase the risk of getting certain lung diseases. People can recover from short-term exposure to low levels of ozone. However, breathing extravagantly levels of ozone or breathing low levels of ozone over a long period of time may have more modify and longer-lasting effects. Ozone has also been found to have positive effects on people. It has turn out to be a very purifying substance. Doctors ar now awake 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 starved tissues) and metabolism.3. It is a powerful antibiotic when applied locally.Ozone is made by nature in the atmosphere or artificially by using high voltages or ultraviolet rays. Ozone and Oxyg en work together efficiently to save 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 used 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
