The approach has been used to examine the VOC emissions from two particleboards. The emission study for the particleboards shows that a fairly good agreement of VOC concentrations between the model prediction and experimental data can be achieved by pre-calculating the partition coefficient (K ) and material age (AGE) and adjusting ma the diffusion coefficient (D ) and initial concentration (C ). Further, the study finds that K m 0 ma only affects short-term emissions while Dm influences both the short-term and long-term emissions. 1. Introduction Numerous field and laboratory studies have found that commonly used dry materials s
