Title: Chlorofluorocarbons


1
Chlorofluorocarbons
  • Destruction to us and our environment
  • By Leo Dorado

2
Substances containing Chlorofluorocarbons
  • Home consumer products
  • Fire extinguishers
  • Spray canisters
  • Refrigerants

3
Chlorofluorocarbons polluters
  • Factories
  • Heavy industry

4
Industrial use of Chlorofluorocarbons (CFCs)
  • Solvents
  • Cleaning Agents
  • Refrigerators
  • Insulation

5
How do Chlorofluorocarbons destroy our
environment?
  • CFCs
  • Release into the atmosphere
  • Ultraviolet light breakdown the CFCs
  • Chlorine atoms in the CFCs are freed
  • These chlorine atoms destroy O-zone (O3)
  • Ultraviolet Radiation increases

6
Where destruction takes place
  • The Stratosphere is where the destruction takes
    place

7
O-zone depletion from Antarctica
Depletion is measured by T.O.M.S. Total O-zone
Mapping Spectrometer The below dark shaded are
shows the amount of depletion around the
Antarctica
8
Ultraviolet radiation
Our amount of ultraviolet radiation exposure can
be reduced with continuing reduction of CFC use
9
Reduction in production of CFCs will help
prevent destruction of
  • Aquatic life
  • Terrestrial Plant life

10
Human Effects
  • Ultraviolet Damage Effects on us
  • Eyes damage
  • Immune System damage
  • Skin damage

11
CFC Reduction brings hope!
  • 1990 Clean Air Act
  • Listing of classes of agents
  • Monitoring and Reporting
  • Phasing out of production
  • Etc.

12
Listed below are the 5 CFCs banned
  • trichlorofluoromethane CFCl3 (CFC-11)
  • dichloro-difluoromethane CF2Cl2 (CFC-12)
  • trichloro-trifluoroethane C2F3Cl3 (CFC-113)
  • dichloro-tetrfluoroethane C2F4Cl2(CFC-114)
  • chloropentafluoroethaneC2F5Cl (CFC-115)

13
Worldwide Production of CFCs
  • Listed below by Thousands of Tons produced

14
Alternative to CFCs
  • HFCs and HCFCs are safer, Yet HCFCs still have
    the potential for O-zone depletion, As seen in
    these illustrations

HFCs (hydro fluorocarbons) HCFCs (hydro
chlorofluorocarbons)
15
CFC reduction impacts everyone
