本研究在俄勒冈州波特兰新建的联邦办公楼进行。主要目标是确定建筑物中挥发性有机化合物（VOC）的主要来源，并测量浓度和源强度的长期（一年）和短期（几天）变化。从入住的第一个月开始，在14个月的时间内，四次收集挥发性有机化合物样本。在最后一次采样期间，在四天（星期五至星期一）内收集样品。分析样品中的单个化合物和总VOC（TVOC）。结果表示为特定的源强度，以及浓度，以便于比较在不同的通风条件下进行的测量。挥发性有机化合物在建筑物中的主要来源被确定为液体过程的复印机和绘图仪发出的特征混合物的C-10-C-11异链烷烃。总挥发性有机化合物的特定来源强度主要来自这些办公室机器的排放物，在研究过程中保持相对稳定。地下停车场的机动车辆被认为是大楼碳氢化合物的另一个主要来源。在最后四天的采样期间，TVOC的具体来源强度变化约五倍，主要反映了办公室机器的使用。
This study was conducted at a newly constructed federal office building in Portland, Oregon. The primary objectives were to identity the major sources of volatile organic compounds (VOC) in the building and to measure both long-term (one year) and short-term (several day) variations in concentrations and source strengths. Samples for VOC were collected on four occasions over a period of 14 months starting with the first month of occupancy. During the final sampling period, samples were collected over four days (Friday - Monday). The samples were analyzed for individual compounds and for total VOC (TVOC). The results were expressed as specific source strengths, as well as concentrations, to facilitate comparisons of measurements made under different ventilation conditions.The primary source of VOC in the building was identified as liquid-process photocopiers and plotters which emitted a characteristic mixture of C-10-C-11 isoparaffinic hydrocarbons. The specific source strength of TVOC, which was dominated by the emissions from these office machines, remained relatively constant over the course of the study. Motor vehicles in the below-ground parking garage were implicated as another major source of hydrocarbons in the building. Over the final four-day sampling period, the specific source strength of TVOC varied by about a factor of five, predominantly reflecting occupant use of office machines.
