CFC's are chlorofluorocarbons. They are made in industry for the use of refrigeration. Firstly they were thought of miracle compounds. But in 1985 everything changed when Dr. Farman and Dr. Mario Molina discovered that there is a hole in the layer of earth protecting us from the harmful UV radiation. The hole was due to these CFC's only. What these CFC's do is that are carried by westerly's to the poles. Due to the low temperature, they take polar stratospheric clouds as the base or catalysts and perform depletion. They decompose the ozone to form their oxide and that oxide again decomposes to form the original element. This is a chain reaction. A single CFC molecule can destroy over 100,000 molecules of ozone. The main sources of CFC's in day to day life are:

  • Deodorants
  • Air Conditioners'
  • Aerosol Cans
  • Spray Cans
  • Vehicles Exhaust.

Why do natural sources of chlorine not cause as much harm to the ozone layer as CFCs?

Natural sources of chlorine, such as sea salt and volcanic eruptions, do not cause as much harm to the ozone layer as chlorofluorocarbons (CFCs) because they are present in much smaller quantities and are not as stable in the atmosphere. CFCs are synthetic chemicals that are specifically designed to be stable and long-lasting, allowing them to reach the stratosphere where they can break down ozone molecules. In contrast, natural sources of chlorine are typically short-lived and do not accumulate in the atmosphere to the same extent as CFCs.


What percent of the sources of chlorine in the stratosphere are CFCS?

Over 80% of the chlorine found in the stratosphere comes from chlorofluorocarbons (CFCs). These compounds can break down in the upper atmosphere, releasing chlorine atoms that can then participate in ozone depletion reactions.


How do CFCs affect animals?

CFCs can harm animals by destroying the ozone layer, which protects them from harmful ultraviolet (UV) radiation. Excessive UV exposure can lead to skin cancer, cataracts, immune system suppression, and disruption of ecosystems. Additionally, CFCs contribute to climate change, which can disrupt animal habitats and food sources.


Are CFCs highly toxic?

Chlorofluorocarbons (CFCs) are non-toxic.


How are cfcs released?

CFCs or chlorofluorocarbons are released when a device that holds it is leaking. Also some aerosols release CFCs into the atmosphere.


Is there a tree which can absorb CFCs?

No, trees do not absorb CFCs (chlorofluorocarbons). CFCs are synthetic compounds used as refrigerants that are primarily broken down in the atmosphere by sunlight. Trees primarily absorb carbon dioxide, not CFCs.


What are the two types of pollutants?

Air pollution and CFCs Ai pollution as all the gasses are polluting all the air which can be causing breathing problems and health problems. CFCs as all the fuels and gasses are creating the CFCs to crash and the hole in the atmosphere is getting bigger by the minute.


How are cfcs used in aerosol?

CFCs were the compressed gas that was used as "spring" to push the can contents out of the container. CFCs have been replaced with HCFCs as a consequence of the Montreal Protocol.


Is chlorofluorocarbon soluble in water does it pollute water?

Chlorofluorocarbons (CFCs) are not very soluble in water. However, if they do come into contact with water, they can contribute to water pollution by contaminating water sources. CFCs are also known to deplete the ozone layer, affecting climate and ecosystems globally.


How do cfcs affect air heath?

By the CFCs being sorced into the air, the sun is Breaking them down into the earth.


What effect do CFCs have on the Earth's stratosphere?

CFCs (Chlorofluorocarbons)What type of substance is it?CFCs are a class of man-made chemicals, generally non-toxic, non-flammable, chemically unreactive, colourless liquids or gases that evaporate easily. They are a group of ozone depleting substances. They damage the Earth's ozone layer, which protects the earth's surface from harmful ultra-violet radiation. CFCs are also powerful greenhouse gases which contribute to global warming.How is it released?Release to the atmosphere is primarily from CFC-containing aerosols, refrigeration equipment and some foams. There are no natural sources of CFCs.
