Ozone hole is the area of the Earth’s atmosphere where abnormal reductions of ozone occur, it is an annual phenomenon observed during the spring in the Polar Regions and is usually followed by a recovery during the summer. In the measurements made in recent times significant reductions in ozone concentrations in the layer, with special emphasis in the area of Antarctica were discovered.

The effects of ozone hole are:

• A deliberate absorption of this radiation can cause disturbances in the body’s immune system.

• The negative effect on the DNA molecule.

• Attacks vision causing cataracts.

• Damages the chromosomes of the skin and can result in cancer and other conditions.

• Plants can be damaged by a lasting exposure.

• Alter aquatic ecosystems, so necessary for biological balance.
