Facts about Ozone Discovered in 1839 by German scientist Christian Friedrich Schonbein Derived from the Greek word meaning ‘to smell” Relatively unstable molecule of 3 oxygen atoms Powerful oxidizing agent

Present Day Atmosphere Major components are: Oxygen: 21% Nitrogen: 78% Argon: .93%

The Process of Ozone Depletion CFCs released CFCs rise into the ozone UV releases Cl from the CFCs Cl destroys ozone Depleted ozone = more UV

Not a hole but a thin layer CFC’s does not drill a hole in the ozone layer But it thins the layer This allows more UV rays to enter the atmosphere

Harmful effects of UV radiation Sunburn Premature aging of skin Suppression of immune system Cataracts Skin Cancer
