Chloroflourocarbons are not directly hazardous to humans, the chlorine in them rises to the ozone and turns the ozone into normal oxygen, which does not protect us from cosmic radiation, hence the hole in the ozone layer.
CFC directly do not cause harm to humans. They deplete ozone which causes harm.
The CFC's are harmful as they react with ozone layer to deplete it. They decompose ozone molecules to deplete them.
They don't. CFCs (chlorofluorocarbons) are non-toxic to humans and animals. They only kill ozone molecules.
Yes, even though they are primarily harmful because of their effect on ozone depletion. CFCs have both effects. The two effects are different. The ozone depletion is worse.
carbon dioxide
The humans destroy ozone by usng CFCs. These are compounds which react with ozone to deplete it.
Yes they did. CFC's were causing depletion to ozone.
humans use products containing CFCs which accumulate in the atmosphere.
Humans are causing the hole in ozone layer by using CFCs. These CFC are the factors responsible for depletion of ozone.
Yes. People developed chemicals such as CFCs (Chlorofluorocarbons) for use in refrigerators and as a propellant gas in aerosols. These CFCs rose high into the atmosphere and caused damage to the ozone layer. the use of CFCs has since been banned and the ozone layer is slowly recovering. Hopefully.
CFCs are neither soluble in water or reactive with it. Rain has no impact on CFCs
Ban on CFC's is a necessity. The ban is necessary because of the harmful effects.
By using CFCs such as aerosols, old fridges, air-conditioning units and polystyrene foam
Countries agreed at the Montreal Conference to ban the use of chlorofluorocarbons (CFCs). It was clear to everyone that CFCs were damaging the ozone layer and this could lead to severe damage to humans. This ban has been the most successful international intervention ever. No CFCs are now being released and scientists hope the ozone level will have self-repaired by 2060 (CFCs hang about in the atmosphere for up to 75 years!).
