name seven chemicals which are responsible for ozone depletion

According to environmental protection act, these substances affect ozone badly are:

1. Chlorofluoro carbons (CFC)
2. Halons
3. Carbon Tetrachloride (CCl₄)
4. Methye chloroform (C(CH₃)Cl₃)
5. Hydrobromo fluoro carbons (HBFC)
6. Hydor chlorofluoro carbons (HCFC)
7. Methyl bromide and
8. Bromochloromethane (BCM)

Avoiding the use of these substances, often referred to as  Green House Gases, will prevent further Ozone depletion.
Look for these ingredients when you buy Refrigerators, Air Conditioners, Dry cleaning products, Fumigants, Fire extinguishers and Cleaning solvents, which is how these substances are commercially consumed most often.
