Which of the following human-oriented pollution substances that destroy the ozone layer in the atmosphere? Correct Answer Chlorofluorocarbons
- Human-oriented ozone-depleting substances are chlorofluorocarbons.
- The main cause of ozone depletion and the ozone hole is chemicals, especially manufactured halocarbon and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs), referred to as ozone-depleting substances (ODS).
- These compounds are transported into the stratosphere by turbulent mixing after being emitted from the surface, mixing much faster than the molecules can settle.
- In the stratosphere, they release halogen atoms through photodissociation, which catalyze the breakdown of ozone (O3) into oxygen (O2).
