fluorocarbons, also known
as CFCs, are industrially produced chemical compounds that contain the elements
chlorine, fluorine, carbon, and sometimes hydrogen that will break down the
protective ozone in the atmosphere. Since CFCs are heavier than air, the process of
CFCs reaching the ozone will generally take from two to five years to get into the
stratosphere. When CFCs reach the stratosphere, the sun's ultraviolet radiation
cause them to break apart. Therefore, the chlorine atoms inside the CFCs are
released and will react with ozone, starting a chemical destruction cycle of ozone. To
show the extent of destruction chlorine can produce, one chlorine atom can break
apart more than 100,000 molecules of ozone. Chlorofluorocarbons are not
naturally produced chemical, but shockingly are all man-made products. CFCs
products and other ozone depleting substance are everywhere and come in all forms
such as: aerosol spray cans, industrial cleaning agents, insulators, Styrofoam's,
coolants, auto air conditioners, home air conditioners and refrigerators (see next the
pie chart on next page for more information). Majority of CFCs contributing to
depletion is the auto air conditioners in our cars. The CFCs inside auto and home air
conditioning systems, as well as in refrigerators can leak out, and eventually will rise
into the atmosphere destroying the ozone layer.
According to Greenpeace, "The manufactures of CFCs and other ozone depleting
products include: Dupont, Elf-Atochem, ICI, LaRouche, Rhone Poulenc, Nippon
Halon, and Allied Signal" (Greenpeace). The total value of all the ozone depleting
products since 1986 exceeded $30.6 billion, with the United States producing a large
There are other elements and man-made chemicals that contribute to the
ozone depletion. Any form of elemental bromine that reacts with ozone is very
violotile. For examaple, methyl bromide is a compound that is used as a ...
