Chlorofluorocarbons (CFCs) are stable and non-reactive compounds, which allows them to persist in the lower atmosphere for a long time before reaching the stratosphere. Their low volatility and high molecular weight enable them to slowly rise through the atmosphere. Once in the stratosphere, CFCs are broken down by ultraviolet (UV) radiation, releasing chlorine atoms that contribute to ozone depletion.
