Answer Details
The pollutants that contribute to the depletion of the ozone layer in the atmosphere are chlorofluorocarbons (CFCs). CFCs are synthetic organic compounds containing chlorine, fluorine, and carbon. They are used as refrigerants, propellants in aerosol cans, and in the production of foam products. When CFCs are released into the atmosphere, they rise to the stratosphere and are broken down by ultraviolet radiation, releasing chlorine atoms. These chlorine atoms then react with ozone molecules, breaking them down and depleting the ozone layer.
