Ozone layer Depletion and the future effects it will have on the population. Harmful effects of the Ultraviolet rays.

The ozone layer diminishes more each year. As the ara of paired ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet radiation rays are allowed to pass through. These rays cause cancer, cataracts, and send packing immunity to diseases.1 What causes the depletion of the ozone layer? In 1970, Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started research on globose biogeochemical cycles as well as the effects of supersonic give aircraft that release nitrogen oxide into the stratosphere.2 In 1974, Molina and Rowland found that human-made chlorofluorocarbons used for clear up foam, cleaning fluids, refrigerants, and repellents transform into ozone-depleting agents.3 Chlorofluorocarbons stay in the atmosphere for some(prenominal) decades due(p) to their long tropospheric lifetimes. These compounds are carried into the st ratosphere where they undergo hundreds of catalytic cycles with ozone.4 They are mortified bug out into centilitre atoms by ultraviolet radiation.5 centilitre acts as the catalyst for breaking down nuclear atomic number 8 and molecular ozone into cardinal molecules of molecular oxygen. The prefatory set of replys that embroil this process are: Cl + O3 -->ClO + O2 and ClO + O -->Cl + O2 The exculpate result: O3 + O -->2O2 Chlorine is ab initio removed in the first equation by the reaction with ozone to form chlorine monoxide.

Then it is regenerated through the reaction with monoatomic oxygen in t he second equation. The net result of the tw! o reactions is the depletion of ozone and atomic oxygen.6 Chlorofluorocarbons (CFCs), halons, and methyl radical bromide are a few of the ozone depletion substances (ODS) that break down ozone under intense ultraviolet light. The bromine and fluorine in these chemicals act as catalysts, reforming ozone (O3) molecules and monatomic oxygen into molecular oxygen (O2). In volcanic eruptions, the sulfate...
