Do any CM's or Imagineers on this board know if the scents that Disney has in its stores, attractions, hotel lobbies, etc. are intentionally (mechanically) created or do they just exist because of certain building materials, cleaning products, etc.?

Just to clarify, I am not complaining - love whatever makes the Haunted Mansion smell like the Haunted Mansion and so on...

I know that this is a weird question, but I have always wondered....thanks!
