What are CFCs why are they harmful to the environment?

Chlorofluorocarbons (CFCs) obliterate the world’s defensive ozone layer, which safeguards the earth from destructive bright (UV-B) beams produced from the sun. CFCs additionally warm the lower air of the earth, changing worldwide environment.

What are CFCs responsible for?

CFCs have been responsible for depleting the ozone layer as they destroy ozone molecules. The ozone layer is a high level layer of gas in the stratosphere. The ozone helps to keep out harmful UV rays, which cause sunburn and damage plants.

How does CFC affect the ozone layer?

Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules. The seasons have an impact on the Antarctic ozone hole. When sunlight returns in the spring, the chlorine begins to destroy ozone.

Do CFCs pollute the air?

Pollutants can also damage the atmosphere above Earth’s surface. A well-known example of this damage is that caused by chlorofluorocarbons (CFCs). CFCs were used for many years as coolant in refrigerators and as cleaning agents. One of the best-known examples of long-range transport of air pollutants is acid rain.

How do CFCs affect humans?

CFCs can generally impair the human immune system, and scientists have linked direct expose to problems with the central nervous system . These problems might include difficulty breathing or injury to the heart, kidneys and liver.

How CFC destroy the ozone layer?

Gaseous CFCs can deplete the ozone layer when they slowly rise into the stratosphere, are broken down by strong ultraviolet radiation, release chlorine atoms, and then react with ozone molecules.

Which is an example of the effect of CFCs?

One example of the consequences of CFCs is the ozone layer hole right above the South Pole. There is evidence to suggest that CFCs, or chlorofluorocarbons, deplete the ozone layer. the problem with this, is that with the depletion of the ozone layer comes a loss of protection from harmful UV radiation from the sun.

How are chlorofluorocarbons used in refrigerants?

Chlorofluorocarbons (CFCs) were commonly used as aerosol spray can propellants. They could also be found in refrigerants in air conditioners and refrigerators. It was discovered that there was a link to the use of CFCs and ozone layer depletion.

How to prevent CFCs leakage in air conditioners?

Ans. Buy air-conditioning and refrigeration equipment that does not use CFCs as a refrigerant. Buy aerosol products that do not use CFCs as propellants. Conduct regular inspection and maintenance of air-conditioning and refrigeration appliances to prevent and minimize refrigerant leakage.

How are halons and chlorofluorocarbons harmful to the Earth?

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth’s protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun.
