Aerosols used to contain CFCs (chlorofluorocarbons) which did not break down easily and so did serious damage to the ozone layer, which usually absorbs ultraviolet (UV) radiation. UV radiation is a major cause of skin melanomas and other cancers.
Thanks to the international treaty The Montreal Protocol on Substances That Deplete the Ozone Layer (1987 - 1999) CFCs have now largely been replaced by other aerosols, HFCs (hydrofluorocarbons) which are serious greenhouse gases.
This has nothing to do with the the possibility of global warming being caused by man and may actually have been a cooling agent for parts of our planet. Ozone is a greenhouse gas that naturally thins over each pole throughout the winter months. This creates a natural hole over each pole during this process. The theory why the Antarctic has not seen warming is due to the cooling effect from the larger hole.
Aerosols contain CFCs,that is , chlorofluorocarbons. These are very harmful for the atmosphere. CFC consists of chlorine molecules which breaks the bond of an ozone molecule. This further accelerates the breaking up of bonds and causes harm ro this layer eventually leading to its depletion.
Yes, they do. They contain CFC's which react with ozone and deplete it.
Aerosols are the substances containing the CFC's. They form chain reaction with ozone and deplete it.
Aerosols react with ozone to deplete it.
Aerosols deplete the ozone by reacting with it. Ban on CFC's have been implemented.
Not now. The CFCs that were used as aerosols in the 1980s are responsible for the depletion of the ozone layer. These have been phased out and scientists hope the ozone layer will have recovered by about 2060.
CFC gases from aerosols and fridges destroy ozone and reduce the thickness of the ozone layer
Not any more. The CFCs that were used as aerosols in the 1980s are responsible for the depletion of the ozone layer. These have been phased out and scientists hope the ozone layer will have recovered by about 2060.It emits gases that damage the ozone layer.
The chemical compound used in aerosols that are thought to be harmful to the Ozone are known as Chlorofluorocarbon or "CFCs" for short.
Aerosols react with ozone. They deplete it.
Aerosols have affected the ozone layer. They have done this as they contain CFC's.
Aerosols are harming the ozone. They contain the synthetic CFC's.
Aerosols deplete the ozone by reacting with it. Ban on CFC's have been implemented.
Yes they do. Aerosols react with ozone to harm it.

The ozone layer does not affect anything. It is a protective layer.
