The ones that do not contain either chlorine or bromine in their molecules.
See "How does refrigerant-nn effect the ozone layer?" in the "Related questions" section below.
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs) are chemicals found in aerosols and refrigerants that are partly responsible for the depletion of the ozone layer. When released into the atmosphere, these chemicals break down ozone molecules, leading to the thinning of the ozone layer.
The ozone depletion potential (ODP) of HFC-134a is 0, meaning it does not contribute to the depletion of the ozone layer. This is because it does not contain chlorine or bromine atoms which are responsible for ozone depletion.
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons are the main chemical pollutants responsible for ozone depletion. These chemicals come from sources like aerosol sprays, refrigerants, solvents, and fire extinguishers, which release them into the atmosphere when used or disposed of.
Refrigerants containing chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are most harmful to the ozone layer. These refrigerants are commonly used in older air conditioning and refrigeration systems. Their release into the atmosphere can lead to ozone depletion.
Ozone pollution is depletion of ozone because of CFC gases. Stopping use of CFC gases which are found in refrigerants can help to stop ozone hole expansion.
Refrigerants release CFC's. They react with ozone to deplete it.
Ozone depletion potential refers to the potential at which the ozone is depleting. Human activities are the main reason for its depletion.
Ozone depletion can be stopped by substitutuing refrigerants with some other gases. It will help stop Global Warming too.
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs) are chemicals found in aerosols and refrigerants that are partly responsible for the depletion of the ozone layer. When released into the atmosphere, these chemicals break down ozone molecules, leading to the thinning of the ozone layer.
Ozone depletion is due to CFC's. These CFC's are released from refrigerators.
The ozone depletion potential (ODP) of HFC-134a is 0, meaning it does not contribute to the depletion of the ozone layer. This is because it does not contain chlorine or bromine atoms which are responsible for ozone depletion.
HCFC's have the lowest ozone depletion potential. These have an ozone depletion potential of 0.
Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and halons are the main chemical pollutants responsible for ozone depletion. These chemicals come from sources like aerosol sprays, refrigerants, solvents, and fire extinguishers, which release them into the atmosphere when used or disposed of.
CFC's have highest potential. They react with ozone and destroy it.
Some refrigerants have chlorofluorocarbons that are harmful to the ozone layer. The CFCs can lead to rapid depletion of the ozone layer in the atmosphere.
Refrigerants containing chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are most harmful to the ozone layer. These refrigerants are commonly used in older air conditioning and refrigeration systems. Their release into the atmosphere can lead to ozone depletion.
It refers to ozone thinning. It is caused by CFC's.
