Answer:
Refrigerators, different types of sprays, air conditioners, fire extinguishers, and paints released chlorofluorocarbons into the air. And this emission contributed to the depletion of the Ozone layer.
Step-by-step explanation:
Refrigerators and air conditioners – Refrigerants are the most common emitter of CFC. If the coolant used in refrigerators, air conditioners, and cars, is not properly disposed of it will leak CFCs into the atmosphere. Either the coolant will evaporate or get into the soil, contaminating both with CFC.
present-day aerosol sprays do not contain CFCs
