Aldehydes and volatile organic compounds (VOCs) emission from plywood of various formaldehyde emission grades were measured using a small chamber method (JIS A 1901). The effect of the formaldehyde emission grade on emission of the other aldehydes and VOCs was discussed. Formaldehyde emission rates of F**** grade plywood were determined to be below 5 mu g/m(2)h by the small chamber method after 21 days. Formaldehyde emission from plywood greatly depended on the adhesives and wood species, and the emission of other aldehydes was not related to the formaldehyde emission grade. The formaldehyde scavenger used in this study had no reducing effect on the emission of aldehydes other than formaldehyde. The primary VOC emission from plywood was terpenes derived from the wood. The amount and variety of VOC emission from plywood depended on the wood species.
