在小型和房间大小的动态环境室中测量了刨花板、中密度纤维板和办公家具的挥发性有机物排放。当考虑片材间和片材内变化时，可以表征小腔室中的产物发射特性。所有产品的甲醛排放系数大约是欧洲低排放规格的两倍，并且在几个月内没有衰减到后者。长期的排放行为无法从短期测量中预测。挥发性有机化合物（VOC）的排放量低，刨花板较高，层压办公家具最高。排放的化合物与其他国家报告的化合物不同。板材产品的挥发性有机化合物排放量比甲醛下降得更快，在两周内达到较低水平，除了甲醛，几个月后发现它成为己醛的低水平来源。
Volatile organic emissions from particleboard, medium density fibreboard (MDF) and office furniture have been measured in dynamic environmental chambers, both small and room-sized. Characterisation of product emission properties in small chambers was possible when inter- and intra-sheet variations were considered. Formaldehyde emission factors for all products were approximately double European low-emission specifications and did not decay to the latter for several months. Long term emission behaviour could not be predicted from short-term measurements. Volatile organic compounds (VOC) emissions were low for the MDF product, higher for particleboard, and highest for laminated office furniture. The compounds emitted differed from those reported in other countries. VOC emissions from the sheet products decreased more quickly than formaldehyde, reaching low levels within two weeks, except for MDF which was found to become a low-level source of hexanal after several months.
