Term Ozone layer
Definition

Region of the Earth’s atmosphere that contains a relatively high concentration of ozone gas that protects life on Earth by filtering 97% to 99% of harmful ultraviolet radiation (UV) coming from the sun.

Depending on the intensity and exposure time, ultraviolet radiation, particularly radiation B, can cause damage to humans, such as skin irritation, premature aging, cataracts, weakened immune system and skin cancer, among others. Because of these effects, it is important to limit exposure to ultraviolet radiation.

In light of these consequences, it is essential to protect the ozone layer by reducing to zero the use of substances which deplete it, especially chlorofluorocarbons (industrial refrigerants and propellants). In 1987, the Montreal Protocol was signed, which put forth the guidelines for the Vienna Convention for the control of substances that deplete the ozone layer. The Protocol was signed and ratified by the Dominican Republic.
