The thinning of “Ozone layer” is resulting due to chlorofluorocarbons, which are used in:

  • (A) Electric heaters and washing machines
  • (B) Spray cans and refrigerators
  • (C) Cigarette lighters and air conditioners
  • (D) Gas cylinders and fuel stoves
  • Chlorofluorocarbons, or CFCs, are human-made chemicals that have traditionally been used as propellants in spray cans, as well as refrigerants in cooling systems. If CFCs escape into the atmosphere, they travel up into the stratosphere, where they are broken down into chlorine atoms by the sun’s ultraviolet radiation. These chlorine atoms can then react with over 100,000 other ozone molecules, causing the depletion of the stratospheric ozone layer.
  • Spray Cans: CFCs were extensively used as propellants in aerosol spray cans (like hairspray and spray paint) because they are non-flammable and stable.
  • Refrigerators: CFCs (often known by the brand name Freon) were the primary cooling agents used in refrigerators and freezers for decades.
