Aldehydes and volatile organic compounds (VOCs) emitted from commercial laminated veneer lumber (LVL) were determined using the JIS small chamber method for 21 days. LVL samples were made from three different veneer species, namely larch (Larix spp.), radiata pine (Pinus radiata D. Don) and sugi (Cryptomeria japonica D. Don), and were bonded with phenol-formaldehyde resins for structural use and melamine-urea-formaldehyde resins for non-structural use. Effects of veneer species, adhesive type, and formaldehyde scavenger on aldehyde and VOC emissions from LVL samples were investigated. The emission factors of aldehydes, VOCs and total VOC (TVOC) decreased during the 21 days in the small chamber with only a few exceptions. The highest emission factors of formaldehyde and acetaldehyde were determined in radiata pine LVL. Adding the formaldehyde scavenger to LVL samples decreased the formaldehyde emission factors by 50% or more. The variety and amount of VOC emissions were strongly dependent on the veneer species. It was therefore concluded that the predominant VOCs derived from the veneer. All the LVL samples used in this study had very low emissions of VOCs according to the indoor air quality guidelines of the Japanese Ministry of Labor, Health and Welfare. © 2006, The Japan Wood Research Society.
