Ozone Layer A General Study

By Ibrahim Afandi Usman

Imagine a typical Hollywood "gotcha" film. The plot involves

the discovery that the apparent "bad guy" is in fact the "good

guy," and that the seemingly nice guy is in fact a fiendishly

evil genius. This is the case with ozone and

chlorofluorocarbons.

Ozone is a molecule consisting of three oxygen- atoms. Its

chemical notation is O3. Ozone is a "bad guy" in that breathing

it is lethal at dosage levels of a few molecules per million air

molecules. This is why ozone at the surface is referred to as a

pollutant. Yet ozone high in the atmosphere screens out

biologically harmful solar ultraviolet radiation, keeping it

from reaching the surface. Such ultraviolet radiation is

destructive of genetic cellular material in plants and animals,

as well as human beings. Without the "ozone layer" high up in

the atmosphere, life on the surface of the Earth would not be

possible as we know it.
