The purpose of this study is to understand the characteristics of total volatile organic compounds (TVOCs) 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 TVOCs concentrations of each test material increased to maximum value in 1-3 days and rapidly decreased in 27 days. The unidentifiable VOCs occupied over 70% of the TVOCs concentration. Toluene occupied the greatest proportion of the identifiable VOCs and benzene, 1,2,4-trimethylbenzene and xylene occupied relatively high proportion of the identifiable VOCs for all test materials. A first-order decay source model in explicit chamber model was used to evaluate the characteristics of TVOCs emission from these furniture materials. Synthetic leather showed the highest initial emission factor and textile had the lowest initial emission factor for TVOCs among tested materials. Also, synthetic leather had the highest emission decay constant and particle board had the lowest emission decay constant for TVOCs.
