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.
By using CFCs such as aerosols, old fridges, air-conditioning units and polystyrene foam
The thinning of ozone layer is the depletion of certain amount of molecules of ozone in the ozone layer. This is a harmful phenomenon.
In the ozone layer. Where the ozone is.
The thinning of ozone layer is mainly due to man made ozone depleting substances. They react with ozone and decompose it.
CFC's are responsible for thinning of ozone. They react with ozone to thin it.
Thinning of ozone layer can be minimized. It can be done by curbing the use of CFC's.
The thinning of ozone layer is the depletion of ozone molecules. It is caused by various man made and natural processes.
damage to ozone layer is called ozone depletion. It is thinning of ozone layer.
The reduction in concentration of ozone molecules is the thinning. It is caused by CFC's.
CFC's are causing its thinning. They react with ozone to deplete it.
Thinning of ozone layer occurs due to UV. UV is fatal for life also.
CFC's that is chlorofluorocarbons are responsible for thinning out ozone layer. These chemicals start a chain reaction within the ozone layer.
