Ozone Layer and its particular Depletion

 Essay on Ozone Level and Its Destruction

•Depletion of ozone and creation of ozone hole

Ozone, actually is a gas having fishy smell and O3 molecules which happens to be the safety shield pertaining to the life in the earth. It absorbs solar ultraviolet rayonnement and thereby protects lifestyle on the earth from a lot of damage including DNA veranderung, skin cancer, blood cancer, etc . In the year 1985, NASA detected the thinning out in the ozone coating leading to the organization of ‘ozone hole' in Antarctica. Ever since then the experts have been frequently monitoring the thickness from the ozone coating. They have located that the width of the ozone layer has become decreasing day by day at the scary rate because of the environmental polluting of the environment. The main causes of the critical depletion of ozone layer are found to be the manmade chlorofluorocarbons (CFC's). These CFC (also known as ferons) are secure non-corrosive and inert compounds containing chlorine, fluorine and carbons. They are extensively employed as the coolants in refrigerators, air conditioning units and as propellants in vaporizador cans and in plastic forms. These CFC molecules, when they escape in to the atmosphere, migrate to the stratosphere and break down to release chlorine atoms in the ozone level. CCL2F2 CCLF2 + Cl---------- (i)

Then your chlorine atom attacks the ozone moleculs

Cl & O3 ClO + O2-------------(ii)

This effect is followed by:

ClO Craigslist + O-------------(iii)

So chlorine atoms are generated in reaction (i), consumed in reaction (ii) and again regenerated in reaction (iii). As a result of this chain reaction, one chlorine atom may destroy 75, 000 ozone molecules. The other agents responsible for the depletion of ozone are NO gas, o2 radicals(O) and hydroxyl radicals(OH). The destruction of ozone layer will certainly lead to the penetration of more and more AS WELL AS radiations which in turn results while skin cancer, blood malignancy, cataracts, etc . and also cause harm to the plant life and crops
