The arsenic is not only hitting the soil but it can also set up as a dirt or dust level right on surface of the wood. So your hand rails, your floor boards, the wooden boards that your little toddler may be crawling around on and playing on, that can have this residue, we call it a dislodgable residue of dust, arsenic dust, right on the surface of the wood and it is a child putting a moistened hand, because the hand goes in the mouth and there is a little bit of saliva on the hand, it is a perfect medium to pick up that dust, bring it, deliver it into the mouth and give your child an arsenic dose.
