The purpose of this study is to understand the characteristics of formaldehyde emission from furniture materials through the small chamber test method. Particle board and medium density fiberboard as wood products, synthetic leather and textile were selected for this study. The formaldehyde concentrations of each test material increased to maximum value in 1-3 days and rapidly decreased in 27 days. A first-order decay source model in explicit chamber model was used to evaluate the characteristics of formaldehyde emission from these furniture materials. Medium density fiberboard showed the maximum value of initial emission factor and synthetic leather showed the minimum value of initial emission factor for formaldehyde. Also, Synthetic leather showed the highest emission decay constant and medium density fiberboard showed the lowest emission decay constant for formaldehyde. These emission parameters were used in estimation of indoor concentration of carcinogens such as formaldehyde in an imaginary residence equipped with furniture made of tested materials.
