halocarbons
Ozone-depleting chemicals
Halocarbons are organic compounds in which one or more hydrogen atoms have been replaced by halogen atoms—fluorine, chlorine, bromine, or iodine.
The category includes chlorofluorocarbons (CFCs), once widely used as refrigerants and aerosol propellants before their role in ozone depletion was discovered.
Some halocarbons persist in the atmosphere for decades, making them potent greenhouse gases.
