Question

Which chemical compounds adversely affect the ozone layer?

Answer 1

Ozone layer:

• Ozone gas forms this layer in the stratosphere at the height of 20-50km from the earth’s surface.
• The layer protects the living organisms from exposure to ultraviolet radiation.

Ozone depletion:

• The chemicals that can deplete or reduce the ozone layer by reacting with the ozone are called ozone-depleting substances (ODS).
• These are usually present in fire extinguishers, aerosol sprays, refrigerators.
• CFCs (Chlorofluorocarbon) compounds are other examples of ODS.
