3. What is Ozone And Ozone layer ?
O3 ( THREE ATOMS OF OXYGEN)
A GAS WHICH IS HARMFULL TO BREATH
OZONE LAYER IS A THIN LAYER IN THE
STRATOSPHERE
 9 TO 18 MILES(15 TO 30 KM) ABOVE THE EARTH’S
SURFACE
IT OBSERVES ULTRAVIOLET RAYS

4. OZONE LAYER

5. WHAT IS OZONE DEPLETION ?
• THE THINNING OF OZONE
LAYER IN THE STRATOSPHERE
• HARMFUL TO NATURE AND
ATMOSPHERE

6. OZONE LAYER DEPLETION PICTURES

7. CAUSES OF OZONE LAYER DEPLETION
 MANUFACTURING OF CHEMICALS EX.
 USE OF
 HALOCARBON REFRIGERANTS
 SOLVENTS
 PROPELLANTS
 FOAM- BLOWING AGENTS
 THE USE OF THE SUBSTANCE LIKE,
 CHALOROFLUROCARBONS (CFCs)
 HYDROCHALOROFLUROCARBONS (HCFCs)
 HALONS
 CARBON TETRACLORID
 METHYL CHLOROFORM
 METHYL BROMIDE.

8. EFFECT ON HUMAN
 SKIN CANCERS
 EYE CATARACTS
 IMMUNE DEFICIENCY DISORDERS

9. ACTION TO PROTECT THE OZONE LAYER
 THE MONTREAL PROTOCOL
 In 1987 , The INTERNATIONAL COMMUNITY ESTABLISHED
THE MONTREAL PROTOCOL ON OZONE LAYER DEPLETING
SUBSTANCES
 OBJECTIVE
 To cut down the production and consumption of ozone-
depleting substances

10. AS AN INDIVIDUAL WHAT CAN WE DO ?
 MAKE SURE THAT IN YOUR HOUSE OLD REFRIGERANT AND
AIR CONDITIONERS ARE DESPOSED OF SAFELY
 MAKE SURE WHEN YOU REPAIR YOUR REFRIGERANTS
TECHNICIAN RECOVER AND RECYCLE OZONE DEPLETING
SUBSTANCES
 BRING AWARENESS ARROUND YOUR FAMILY ABOUT OZONE
DEPLETING SUBSTANCES
