How is the ozone layer destruction?

How is the ozone layer destruction?

Ozone Depletion. When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created.

What are the effects of ozone depletion PDF?

Ozone depletion is allowing the UV radiation to earth surface. The exposure to these radiations is severely affecting all life forms on earth, especially the humans. Permanent or temporary blindness, skin cancer and immunity suppression are the main effects of these radiations reported by various researchers on humans.

What is ozone layer and its effects?

The ozone layer is a natural layer of gas in the upper atmosphere that protects humans and other living things from harmful ultraviolet (UV) radiation from the sun.

How does ozone layer depletion affect human life?

Ozone depletion can cause increased amounts of UV radiation to reach the Earth which can lead to more cases of skin cancer, cataracts, and impaired immune systems. Too much exposure to UV is believed to be contributing to the increase in melanoma, the most fatal of all skin cancers.

What are the causes of ozone layer depletion PDF?

The main causes responsible for the depletion of the ozone layer are listed below:

  • Chlorofluorocarbons.
  • Unregulated Rocket Launches.
  • Nitrogenous Compounds.
  • Natural Causes.
  • Effects on Human Health.
  • Effects on Animals.
  • Effects on the Environment.
  • Effects on Marine Life.

What is harmful for ozone layer?

Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms.
