What are the characteristics of CFC and HCFC refrigerants and how do these refrigerants contribute to ozone depletion?
They were made and used because they are extremely stable, they had useful gas-to-liquid transition temperatures, and they were cheap (fluorine production is dirty, dangerous, and hence expensive).
They contribute to ozone depletion because they are so stable they can only be brokne down in the intense radiation of the ozone layer, and their chlorine payload is released to do its dirty deed over and over.

What are the chemicals in aerosols and refrigerants partly responsible for the depletion of the ozone layer?
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.
Do Volcanoes and Oceans contribute to the Ozone Depletion?
Volcanoes release sulfur dioxide and ash into the atmosphere, but their impact on ozone depletion is minimal compared to human activities. Oceans do not contribute to ozone depletion but play a role in absorbing harmful ultraviolet radiation.
What types of chemical pollutantsare responsible for ozone depletion. where do these chemicals come from?
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.
What is the ozone depletion potential of HFC-134a?
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.
Which refrigerants have the lowest ozone depletion potential?
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.
Why are refrigerants responsible for ozone layer depletion?
Refrigerants release CFC's. They react with ozone to deplete it.
What can humans do to the ozone layer?
Human can help prevent ozone layer depletion. They can stop using CFC gases like refrigerants and contribute for better tomorrow.
Why are CFC are used in refrigerators as refrigerants?
CFCs (chlorofluorocarbons) were used as refrigerants due to their effectiveness at cooling and non-toxic properties for humans. However, it was later discovered that CFCs contribute to ozone depletion, leading to the development and use of alternative refrigerants.
What is the future plus ozone depletion?
Ozone depletion can be stopped by substitutuing refrigerants with some other gases. It will help stop Global Warming too.
What is the relationship between deplete the ozone layer and the refrigerants?
Ozone depletion is due to CFC's. These CFC's are released from refrigerators.
What are the chemicals in aerosols and refrigerants partly responsible for the depletion of the ozone layer?
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.
Why Refrigerant must not be vented because of what?
Refrigerants must not be vented into the atmosphere because they are harmful to the environment. When released, they contribute to ozone depletion and global warming. Proper disposal or recycling of refrigerants is necessary to prevent adverse effects on the environment.
Do Volcanoes and Oceans contribute to the Ozone Depletion?
Volcanoes release sulfur dioxide and ash into the atmosphere, but their impact on ozone depletion is minimal compared to human activities. Oceans do not contribute to ozone depletion but play a role in absorbing harmful ultraviolet radiation.
What refrigerants does not contain chlorine?
Refrigerants that do not contain chlorine include hydrocarbons like propane and butane, as well as some newer synthetic refrigerants such as HFCs (hydrofluorocarbons) and HFOs (hydrofluoroolefins). These chlorine-free refrigerants are considered more environmentally friendly as they do not contribute to ozone depletion like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs).
What types of chemical pollutantsare responsible for ozone depletion. where do these chemicals come from?
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.
What activities of men contribute the depletion of the ozone layer?
The use of CFC contributed to depletion of ozone. It is because they react with ozone to decompose it.
What is the ozone depletion potential of HFC-134a?
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.
