PATH set in /etc/Environment
PS1 set in /etc/bash.bashrc

TERM is probably set when a terminal is opened (e.g. getty). See

Code:

man login

for example

Ok .
And other variables ... ?

Variables can be set/unset at any time.

Several are set by your shell, depending on how it is started, for instance.
See

Code:

man bash

for bash shell.

Do you have any specific variables in mind?

Code:

#nano

#echo $TERM

#TERM=rxvt
'rxvt' unknown terminal type
#rxvt
rxvt: can't open display: 0
