materials and method used for ozone layer depletion
Answers
Answer:
industry and harmful toxic gases makes ozone depletion.
Ozone-depleting substances are industrial compounds – such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) – which diminish stratospheric ozone. ODS refrigerants are used in cooling mechanisms such as air conditioners or refrigerators. ... ODS compounds can contribute significantly to global warming.
The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants and foam-blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), 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.Once in the stratosphere, they release halogen atoms through photodissociation, which catalyze the breakdown of ozone (O3) into oxygen (O2).Both types of ozone depletion were observed to increase as emissions of halocarbons increased.
