However, when released into the upper atmosphere, their carbon-chlorine bonds are easily broken by solar radiation to release chlorine radicals (unstable chlorine atoms).

Refrigerant Fluorocarbons, especially chlorofluorocarbons, became commonplace in the 20th century, but they are being phased out because of their ozone depletion effects. Other common refrigerants used in various applications are ammonia, sulfur dioxide, and non-halogenated hydrocarbons such as propane.

Chlorofluorocarbons (CFCs): Refrigerants that Cause Ozone Layer Depletion It has been proved that CFCs are a major cause of depletion of the earth’s stratospheric ozone layer and contribute to the greenhouse effect (global warming). Presently large quantities of CFCs are being used as refrigerants in a number of refrigerating and air-conditioning systems.Though the refrigerant moves in a closed cycle, there are lots of leakages that escape to the atmosphere and cause destruction of the ozone layer.hlorofluorocarbons (CFCs) have been found to cause the depletion of the ozone layer. The ozone layer prevents ultraviolet radiations of the sun from coming on the earth. This article describes the process of damaging effects of CFCs. slide 1 of 3.

- Chlorofluorocarbons, CFCs, have been used as the blowing agents in the past, but because of the damage that chlorofluorocarbons can do to the ozone layer, chemists are actively seeking alternatives for all of the jobs that CFCs have done in the past.e are glad to have the ozone layer in the stratosphere removing these wavelengths of radiant energy, because these wavelengths can cause problems, including skin aging, skin cancer, and crop failure.

CFCs: Definition, Properties & Uses What Are CFCs? CFCs are short for the compound, chlorofluorocarbon, which contain carbon, chlorine, and fluorine. Chlorofluorocarbons are more commonly referred to as CFCs or, when used for refrigeration, CFCs are also known as freon. Developed in the 1930s as a safe alternative to ammonia, usage of CFCs grew rapidly because of its usefulness and convenience throughout most of the 20th century.

- The ozone layer is essential for complex living organisms (like you and me) to exist. Without the ozone layer, all but very simple life forms would be destroyed by the action of ultraviolet light. Some chemicals, particularly CFCs, destroy ozone in the upper atmosphere.A CFC is a chlorofluorocarbon molecule. It is similar to an alkane with all the hydrogen atoms replaced with chlorine and fluorine atoms.In the presence of ultraviolet light a CFC molecule will decompose producing highly reactive chlorine free radicals.These chlorine free radicals will react with ozone molecules and turn them back into oxygen molecules.he ozone layer is essential for complex living organisms (like you and me) to exist. Without the ozone layer, all but very simple life forms would be destroyed by the action of ultraviolet light. Some chemicals, particularly CFCs, destroy ozone in the upper atmosphere.

Chlorofluorocarbons (CFCs): Refrigerants that Cause Ozone Layer Depletion So what is happening because of the CFC refrigerants is that the protective ozone layer is getting converted into incapable oxygen. Due to this the amounts of ultraviolet rays reaching the surface of the earth becomes very high and then causes excessive heating in the environment, called the greenhouse effect.hlorofluorocarbons (CFCs) have been found to cause the depletion of the ozone layer. The ozone layer prevents ultraviolet radiations of the sun from coming on the earth. This article describes the process of damaging effects of CFCs. slide 1 of 3.

Chlorofluorocarbons (CFCs) Chlorofluorocarbons enter the body primarily by inhalation of air containing chlorofluorocabons, but can also enter by ingestion of contaminated water, or by dermal contact with chlorofluorocarbons. Inhalation of high levels of chlorofluorocarbons can affect the lungs, central nervous system, heart, liver and kidneys. Symptoms of exposure to chlorofluorocarbons can include drowsiness, slurred speech, disorientation, tingling sensations and weakness in the limbs.

- Chlorofluorocarbons and ozone. Many people have heard that the ozone hole is caused by chemicals called CFCs, short for chlorofluorocarbons. CFCs escape into the atmosphere from refrigeration and propellant devices and processes. In the lower atmosphere, they are so stable that they persist for years, even decades.he ozone hole is the region over Antarctica with total ozone of 220 Dobson Units or lower. This map shows the ozone hole on October 4, 2004.

Laughing gas is biggest threat to ozone layer Researchers suggest use of the compound – which is produced by the breakdown of nitrogen in fertilisers and sewage treatment plants – should be reduced to avoid thinning the protective ozone layer that blankets the Earth. The ozone layer shields Earth from the sun’s ultraviolet rays, which increase the risk of cancer and threaten crops and aquatic life. Human-produced chemicals called chlorofluorocarbons (CFCs) made headlines in the 1980s when it became clear they were eating a hole in the ozone layer above Earth’s polar regions.
