Volatile organic compounds (VOCs) emitted from various sources may adversely affect human health,comfort and performance. In particular, formaldehyde has been identified as a major indoor pollutantwhose emission is controlled by workstation systems. Engineered wood products such asparticleboards have widely been used with wood veneer and laminate to form work surfaces ofworkstation systems, which is a major formaldehyde emission component. The emission rate offormaldehyde depends on the composition of each material layer, temperature and moisture content inthe materials.
VOC emissions from building materials are assumed to cause irritation of eye and the upper airways (sensory irritation, SI) in the indoor environment. Four finishing products, two PVC floorings and paints, were selected to this study: PVC(+) and Paint(+) were accepted whereas PVC(-) and Paint(-) were not acceptable in the human sensory evaluation. SI potency of VOC mixtures representing the material emissions were tested by the mouse bioassay (ASTM E981-84 ). Both the paint mixtures were much poorer irritants than PVC(-), but stronger than PVC(+).
