The main danger of CFCs is that they deplete the ozone layer giving rise to increased penetration of UV rays on to the earth. This heats up earth's surface, melts glaciers thereby flooding many parts of the world. They also reduce the oxygen levels.

Are CFCs always dangerous to the ozone layer?

yes


What are the dangerous rays that harms ozone layer?

No dangerous rays harm the ozone layer. CFCs (chlorofluorocarbons) harm the ozone layer. The ozone layer actually protects us and theearth from dangerous ultraviolet radiation.


Are CFCs highly toxic?

Chlorofluorocarbons (CFCs) are non-toxic.


How are cfcs released?

CFCs or chlorofluorocarbons are released when a device that holds it is leaking. Also some aerosols release CFCs into the atmosphere.


Is there a tree which can absorb CFCs?

No, trees do not absorb CFCs (chlorofluorocarbons). CFCs are synthetic compounds used as refrigerants that are primarily broken down in the atmosphere by sunlight. Trees primarily absorb carbon dioxide, not CFCs.


How are cfcs used in aerosol?

CFCs were the compressed gas that was used as "spring" to push the can contents out of the container. CFCs have been replaced with HCFCs as a consequence of the Montreal Protocol.


How do cfcs affect air heath?

By the CFCs being sorced into the air, the sun is Breaking them down into the earth.


Why was the refrigerator and freezer industry pressured to find an alternative coolant to chlorofluorocarbons?

chlorofluorocarbons (CFCs), which were believed to cause depletion of the ozone layer that protects the planet from dangerous cancer-causing ultraviolet rays


Are CFCs are synthetic chemicals?

no.


What is short for chloroflourocarbons?

CFCs


Can rain demolish CFCs?

Rain can help remove CFCs from the atmosphere by acting as a natural cleanser. When CFC molecules are exposed to rain, they can react with water and break down into less harmful compounds that are eventually washed out of the atmosphere.


What can we do to reduce CFC's?

The Montreal Agreement of September 16, 1987, laid down rules for the phasing out of the production and use of CFCs (chlorofluorocarbons). Every country in the world agreed and ratified this, the only time this has happened in history. There are now no CFCs in use (except perhaps in the air conditioners of very old cars), or production (unless a rogue state or company is producing them illegally). CFCs were replaced in most cases by HCFCs (hydrochlorofluorocarbons), which were not so dangerous for the ozone layer. The Montreal Agreement was extended to phase out HCFCs by 2015. CFCs and HCFCs have now been replaced by HFCs (hydrofluorocarbons) which do not contain chlorine, and so do not destroy ozone. However, CFCs are dangerous greenhouse gases, much more potent than carbon dioxide, so their threat to global warming is very real. Scientists are now looking for a safer option to HFCs. There are still levels of CFCs in the atmosphere, which may lead to ozone layer depletion, and further leading to loss of lives on earth due to skin cancer, etc. caused by the ultra-violet radiation.
