Its atmospheric lifetime is approximated between 31 and 42 years.

SF6 is very persistent, with an atmospheric lifetime of more than a thousand years.

It has an estimated atmospheric lifetime of 800-3200 years.

By comparison, halon 1301 has an atmospheric lifetime of about 75 years.

CFCs have very long atmospheric lifetimes, ranging from 50 to over 100 years.

It has an atmospheric lifetime of about eight years.

Carbon dioxide has a variable atmospheric lifetime, and cannot be specified precisely.

E.g., NO has a mean atmospheric lifetime of 114 years.

Nevertheless, their potential for global warming is considerable, because many of them have a long atmospheric lifetime (up to fifteen years).

Correspondingly, sea salt aerosols have a wide range of atmospheric lifetimes.
