Fluorocarbons from spray cans and industrial sources last at least 30 years in the lower atmosphere, according to recent NOAA reports of the Geophysical Monitoring for Climate Change Program in Boulder, Colorado.
The sampling results were applied to a model that computes the lifetimes of the two fluorocarbons that are capable of destroying stratospheric ozone, F-11 and F- 12. Calculations show that the lifetime of F-11 in the atmosphere is most likely 86 years, while that for F-12 is 113 years. It was also possible to compute minimum lifetime; 30 years for F-11 and 33 years for F-12.
