Which countries stop destroying ozone layer?
At the Montreal Conference all countries eventually agreed to stop the production of CFCs (chlorofluorocarbons) which were destroying the ozone layer.
Are there hairsprays that still have CFCs in them?
Probably not. There may be some small companies in developing countries still using CFCs but all major countries have phased them out by the end of last century. Hairsprays have other chemicals which may not be good for the atmosphere either. We may have to wait and see.
Which gas contributes to both global warming and the deterioration of the ozone layer?
CFCs (chlorofluorocarbons) are the gases responsible. Fortunately the Montreal Treaty got all countries to stop making this gas and the ozone layer is repairing itself.
Can rain demolish CFCs?
CFCs are neither soluble in water or reactive with it. Rain has no impact on CFCs
What substitutes for CFCs came into being after scientists discovered that CFCs were harming the atmosphere?
Replacements for CFCs (dependding on use) included:HCFCsNitrogenAirPropane
Which countries stop destroying ozone layer?
At the Montreal Conference all countries eventually agreed to stop the production of CFCs (chlorofluorocarbons) which were destroying the ozone layer.
What agreement was signed in 1988 by forty countries who were concerned about the ozone layer?
The Montreal Agreement is a successful international treaty to stop the production of CFCs (chlorofluorocarbons).
Is the ozone problem caused by the burning of fossil fuels?
No, burning fossil fuel has little to do with this. The ozone problem was caused by the addition of CFCs (chlorofluorocarbons) to the atmosphere during the 20th century. The Montreal protocol successfully convinced all countries to stop producing CFCs and the ozone layer should have repaired itself by around 2050.
What is the consequence of an increase of CFCs - chlorofluorocarbons - in the atmosphere?
The consequence was the destruction of the ozone layer. However, the Montreal Protocol got all countries in the world to agree to stop the production of CFCs (chlorofluorocarbons). This happened, and the ozone layer is actually repairing itself and should be fully recovered by 2050 (unless we emit some other polluting chemical in the interim).
Are there hairsprays that still have CFCs in them?
Probably not. There may be some small companies in developing countries still using CFCs but all major countries have phased them out by the end of last century. Hairsprays have other chemicals which may not be good for the atmosphere either. We may have to wait and see.

What is the term for gases produced by aerosols and manufacturing that destroy the ozone layer?
chlorofluorocarbons (CFCs) "ozone depleting substances" are more generic, since other chlorine- and bromine-containing molecules, which are produced by Man, have been found "up there" too. Note that CFCs are not "produced by aerosols", but were intentionally manufactured for the purposes of refrigerant and propellant. Not too many countries are still making / using CFCs.
When will CFC stop to react with Ozone?
The world has agreed to stop manufacturing CFCs. If no other pollution damages the ozone layer it should have recovered by about 2050.
What is the term for gases produced by aerosols manufacturing that destroy the earth's ozone layer?
chlorofluorocarbons (CFCs) "ozone depleting substances" are more generic, since other chlorine- and bromine-containing molecules, which are produced by Man, have been found "up there" too.

Can rain demolish CFCs?
CFCs are neither soluble in water or reactive with it. Rain has no impact on CFCs
Do polystyrene containers play a part in the thinning of ozone layer?
At one time, polystyrene foam was blown using CFCs as stable gases for initially filling the little voids in the foam. The CFCs would later diffuse into the atmosphere. Polystyrene foams in most countries are not blown using CFCs as a blowing agent today.
When were CFCs banned?
The Montreal protocol bans CFC's from modern countries and was signed on Sept. 16, 1987. Is was still being made and used as of this year in some countries.
