One possible way is to simply remove those user configuration files.  
Another one is to grep through the existing files, as variables are  
usually set using their name directly. Third option is to try the  
various switches available with bash to exclude some of the  
configuration files. A new/virgin user account might be useful for  
all the options.

Typical GUI users don't even know environment variables exist ...
