appauvrissement de l'ozone stratosphérique
Definition

Damage of the ozone shield by chemicals released on Earth. The main chemicals that are depleting stratospheric ozone are chlorofluorocarbons (CFCs), which are used in refrigerators, aerosols, and as cleaners in many industries, and halons which are used in fire extinguishers. The damage is caused when these chemicals release highly reactive forms of chlorine and bromine.
