Oh, there was one girl in my HS biology class... wait, we're talking about formaldehyde. How much is there really in the flooring. How fast does it emit? Does it get dissipated? Safely? It's like these ********* ******** about lead or dichlorodifluoromethane. Some of the exposure limits are just ridiculous. Yes, I typed asterisks. A bunch of them, cause I really meant it.
