How much aluminum oxide or AO (in weight proportion, or ounces or milligrams) is often in engineered hardwood floor finishes, and how much of the AO is released into the air through normal usage (walking on the floor, typical activities) or if there are small scratches?Is the amount of AO released into the air on such flooring significant versus background AO levels?I realize that sanding/refinishing an engineered floor will release much more AO into the area, but my main concern here is about general household use.Thanks, Michal
Unless you walk around with sandpaper glued to your shoe soles I doubt there would be any detectable amount released from normal usage. There are certainly far more substances I would be concerned about in a house environment than that. If you are really obsessed about it, contact the flooring manufacturer for data.
