WebEvidence that chlorine is causing the ozone depletion: According to the hypothesis, when CFCs break down they produce chlorine, which destroys ozone and generates chlorine monoxide. So scientists reasoned that if these reactions were occurring, ozone levels should be low where chlorine monoxide levels are high and vice versa.

WebUV radiation breaks a chlorine atom off a CFC molecule. The chlorine atom breaks an ozone molecule apart into an oxygen molecule (O 2) and a chlorine monoxide molecule (ClO). A … WebClO + O = Cl + O2. The industrial production of CFCs started in the 1920’s, causing an average reduction of the ozone layer of 3 per cent. Fortunately, chlorine has “natural enemies” as well, such as methane (CH4). Thanks to them, the natural ozone layer could recover over 50 years, as long as CFCs are no longer used on a global level. cultural changes in nasaWebThe chlorine atom breaks an ozone molecule apart into an oxygen molecule (O 2) and a chlorine monoxide molecule (ClO). A free oxygen atom bumps the chlorine atom out, forming an oxygen molecule. This leaves the chlorine atom free to attack and destroy another ozone molecule.

WebChlorine monoxide radicals will further react with atomic oxygen to form more chlorine radicals. ClO(g) + O(g) → Cl(g) + O 2 (g) This process will continue and constantly regenerate chlorine radicals. This, in turn, will lead to the breakdown of ozone. Hence, CFCs are transporting agents that are responsible for damaging the ozone layer.

WebOne chlorine can destroy 100,000 molecules of ozone. It is destroyed more quickly than it is created. Some compounds release chlorine and bromine on exposure to high ultraviolet light, which then contributes to ozone layer depletion. Such compounds are known as Ozone Depleting Substances (ODS). WebThe ozone gradually returns to normal levels by late November. The new results reported by the JPL researchers show unusually large amounts of chlorine nitrate, one of two molecular forms in which chlorine released from chlorofluorocarbons is stored in the stratosphere. The other reservoir is hydrochloric acid.

Webbreakdown (photolysis) of ozone by solar radiation with wavelengths less than 310 nm. The oxygen atom (O) formed then reacts with water to form OH. This reaction mechanism is why a small amount of ozone is essential in the troposphere.
