Question :-
What is CFC ? Is it harmful for our health ? explain.
Answer :-
CFC stands for Chlorofluorocarbons.
CFCs are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine.
They are used in the manufacture of :-
- aerosol sprays
- blowing agents for foams and packing materials
- as solvents
- as refrigerants
CFCs are classified as halocarbons, a class of compounds that contain atoms of carbon and halogen atoms.
Individual CFC molecules are labeled with a unique numbering system.
_______________
Harmful effects of CFCs :-
CFCs when released in atmosphere this gas particles reaches upto ozone layer and following happens :-
- The destruction of an ozone molecule by a chlorine atom. UV radiation breaks a chlorine atom off a CFC molecule.
- The chlorine atom breaks an ozone molecule apart into an oxygen molecule (O2) and a chlorine monoxide molecule (ClO).
- A free oxygen atom bumps the chlorine atom out, forming an oxygen molecule.
- This leaves the chlorine atom free to attack and destroy another ozone molecule.
Stratospheric ozone loss can result in potential harm to human health and the environment, including:
- increased incidence of skin cancer and cataracts
- immune system system damage
- damage to terrestrial and aquatic plant life
- increased formation of ground-level ozone (smog)
