Beginning of paper
Ozone is a relatively unstable form of molecular oxygen containing three oxygen
atoms produced when upper-atmosphere oxygen molecules are split by ultra violet
light. Stratospheric ozone is found in a broad band, extending generally from 15
to 35km above the earth. Although the ozone layer is sur ....

.... radiation) in a reaction that liberates an atom of
chlorine, which destroys ozone by oxidising with the Ozone molecules, forming
Cl-O and Oxygen. One atom of chlorine can destroy 10,000 ozone molecules! Atoms
containing bromine, nitrous oxide, and hydrogen oxide radicals are also
primarily dangerous. As a result, the Ozone in the stratosphere has been reduced
to such an extent that ozone holes are appearing around the globe, in particular
one over Antarctica that in 1995 measured 8.2 milli ....
