Chlorofluorocarbons (CFCs) are the primary chemicals responsible for the depletion of the stratospheric ozone layer. When CFCs reach the stratosphere, they are broken down by UV radiation, releasing chlorine atoms which catalytically destroy ozone molecules.
Ozone layer in the stratosphere is affected by the increase in the atmospheric concentration of :
