Volatile organic compound (VOC) emissions from furnishings have created a major indoor air pollution problem in China. The aim of this study was to investigate the VOC emission of larch particleboard under different processing conditions. VOCs collection chamber, parts per billion VOC monitor, and gas chromatography-mass spectrometer were used to analyze the VOC components and quantities. The results were shown as follows: (1) concentration and emission rate of VOCs were significantly affected by hot-pressing temperature and time. With the increase of hot-pressing temperature and time, both the earlier emission concentration and the amount of total volatile organic compounds increased. (2) The composition of VOCs was also influenced by temperature and time, especially the variety of terpene, benzene, and derivative. The existence and quantities of esters were still the main components of VOCs emissions.
家具释放的挥发性有机化合物（VOC）在中国造成了主要的室内空气污染问题。本研究的目的是研究不同加工条件下落叶松刨花板的 VOC 排放。采用挥发性有机化合物收集室、十亿分之几 VOC 监测仪和气相色谱-质谱联用仪分析 VOC 成分和数量。结果表明：（1）VOC 的浓度和排放率受热压温度和时间的显著影响。随着热压温度和时间的增加，早期排放浓度和总挥发性有机化合物的量都增加。（2）VOC 的组成也受到温度和时间的影响，特别是萜烯、苯和衍生物的种类。酯的存在和数量仍然是 VOC 排放的主要成分。
