Off gassing/outgassing.
Mrs. D mentioned hard wood floors from China. Ours are premade hardwoods, but I don't know if they are from China. I thought they would be a much safer option than doing all the finishing work here. Maybe not. Formaldehyde seems to be the issue with this type of floor, but I can't find any info on neuropathy/nerve damage from formaldehyde. It mostly seems linked to cancers.

I have always been so careful of buying furniture and safe carpeting made of wool because I was aware of the off gassing toxins. Never thought about premade bathroom vanities and floors.
So, I am doing my homework. I came across this great website and they have 4 sizable free download books with tons of information on hazardous materials. Really great stuff that we should all be aware of especially us idiopaths
