Unsetting an exported environment variable

I am using export to set an environment variable.

export OPCON_VERBOS=${vb}

How can I then unset it later so that it stops being define anymore?

Sotto Voce

unset OPCON_VERBOS

OPCON_VERBOS=

OPCON_VERBOS=""

The unset removes the environment variable (and its value). The others keep the environment variable, but remove its value.
