Are CFCs always dangerous to the ozone layer?
yes
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 CFCs and HCFCs have now been replaced by HFCs (hydrofluorocarbons) which do not contain chlorine, and so do not destroy ozone.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.
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.
Can rain demolish CFCs?
CFCs are neither soluble in water or reactive with it. Rain has no impact on CFCs
Are CFCs highly toxic?
Chlorofluorocarbons (CFCs) are non-toxic.
What substitutes for CFCs came into being after scientists discovered that CFCs were harming the atmosphere?
Replacements for CFCs (dependding on use) included:HCFCsNitrogenAirPropane
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.
What are the two types of pollutants?
Air pollution and CFCs Ai pollution as all the gasses are polluting all the air which can be causing breathing problems and health problems. CFCs as all the fuels and gasses are creating the CFCs to crash and the hole in the atmosphere is getting bigger by the minute.
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.
What is short for chloroflourocarbons?
CFCs
Are CFCs are synthetic chemicals?
no.
