Chlorine from ocean water vapor is the primary issue. Second would be a lack of sunlight, which is why the issue only occurs during the winter months above each pole.
The chemical compound which is responsible for the depletion of ozone layer is CFC. They are chlorine and fluorine compounds which react with ozone to deplete it.
CFC's are responsible. They react with ozone to deplete it.
aerosols, chlorofluorocarbons and other industrial effluents are responsible for the depletion of ozone layer.
Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion.
CFC's are responsible. They react with ozone to deplete it.
Manmade chemicals like chlorofluorocarbons and bromofluorocarbons are the major depleters of the ozone layer. The chlorine and bromine separate from the CFCs (chlorofluorocarbons) and destroy the ozone molecules.
CFc's and freons are responsible. They cause the depletion of ozone layer. The depletion is due to Chlorine and Fluorine.
CFC's are responsible for ozone depletion. They react with ozone to deplete it.
Chemical
Chlorine is responsible for O3 depletion. It forms a chain reaction.
The gas responsible for ozone depletion is CFC. It reacts with ozone to deplete it.
CFC's are responsible. They deplete the ozone layer.
