The best guess I can give you is that the original plywood
dresser is either fir or spruce; which are your common plywoods.
The doors appear to be oak. To tell for sure I need a much better
lit up picture of the inside of the dresser where the wood is untreated. As for the types of poisonous woods & the reasons ; I
think that was answered in your more recent thread above. If you can get a better pic feel free to p.m. or e-mail it to me.
