In 1974, Mario Molina and Sherwood Rowland demonstrated that
CFC gases, freons
, have a damaging effect on ozone in the atmosphere. Freons had many uses, including propellants in spray cans and refrigerants in refrigerators. By limiting the use of freons, the depletion of the ozone layer has been slowed.

What is O3?
Ozone
(O3) is a highly reactive gas composed of three oxygen atoms. It is both a natural and a man-made product that occurs in the Earth’s upper atmosphere. (the stratosphere) and lower atmosphere (the troposphere). Depending on where it is in the atmosphere, ozone affects life on Earth in either good or bad ways.
Where are CFCs usually found?
Chlorofluorocarbons (CFCs) are anthropogenic compounds that have been released into the atmosphere since the 1930s in various applications such as in
air-conditioning, refrigeration
, blowing agents in foams, insulations and packing materials, propellants in aerosol cans, and as solvents.
What does CFCs stand for?
Chlorofluorocarbons
(CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.
