Im refering to the construction of the floor, manmade, in that its wood and plastics bonded with glue. . A surface finish will cure out in weeks. But there is alot of info on VOCs in particle board, insulation, carpet and essentialy any man made product that can out gas for years. Formaldehyde is one chemical ever present in new construction , so much so that non formaldehyde inulation is being made , its at Menards. Before tight houses these wernt issues of major concern . VOCs are bad and with tight houses make some people real sick. Oregon Scientific makes a VOC alarm-meter, for 100. Point is wood is wood, nicer to look at and that things we make out of OIL have unseen consequences as to future health problems . To many unknown chemicals in to many products. Amoco in Chgo shut down a major development lab after many people developed brain and other cancers. What we make today we only learn about tomorrow. Just one more reason for the REAL stuff.
