The aim of this study was to investigate the formaldehyde emission sourced from composite furniture components used in furniture industry in different chamber conditions. For this purpose, oriental beech (Fagus orientalis Lipsky), scotch pine (Pinus sylvestris Lipsky), particleboard, fibreboard, MDFlam, melamine-coated chipboard, poplar plywood, and beech plywood samples were prepared according to TS 2470 (1976). Formaldehyde emission emitted from samples was determined as the principles of TS EN 717-1 (2006) in three different environments. Formaldehyde emission was measured using a gas detector. Results showed that the formaldehyde emission value in laminated scotch pine (450.4 ppb) was found higher than oriental beech (414.3 ppb). The highest formaldehyde emission in wood-based panels was determined in particleboard (1725 ppb); and the lowest in beech plywood (392.5 ppb). In term of test environment the highest emission value (481.9 ppb) was found in 3rd environment (40 degrees C -humidity 35% summer and dry); and the lowest (390.1 ppb) in 1st environment (10 degrees C -humidity 95% - winter and humid). Uncoated - edge samples were emitted higher levels of formaldehyde emission than coated-edge samples. As a result, using wood-based panels inside with high temperature raise the formaldehyde emission levels. It can be said that using laminated wood with adhesive which is low urea-formaldeyhde rate and before using wood-based panel is treated reduce emission levels instead of wood-based panels increases indoor air quality.
