Indoor/outdoor relationships were identified for selected volatile organic compounds over the course of five consecutive days in three homes. Indoor sources of individual compounds were meant in one or more homes. Personal monitoring samples and breath analyses were obtained from volunteers in each home. A period of outdoor air stagnation occurred during one evening and morning of the study. Two results from the study that must be considered in future investigations of VOC exposure are 1) periods conducive to accumulating outdoor VOC can make substantial contributions to indoor values and 2) for homes without indoor sources of individual compounds the indoor values are driven by the outdoor values of a VOC. The primary results do not contradict previous TEAM studies which indicate that when indoor sources of a particular VOC are present the personal exposure and microenvironmental exposures are effected primarily by indoor contributions. Future comparisons of external exposure values with human breath analysis studies must be designed to more closely reflect the time interval associated with the half time of elimination for a particular VOC.
在三户家庭中连续五天对选定的挥发性有机化合物进行了室内/室外关系识别。个别化合物的室内来源存在于一户或多户家庭中。从每户家庭的志愿者那里获取了个人监测样本和呼吸分析样本。在研究的一个晚上和上午出现了室外空气停滞期。该研究的两个结果在未来对挥发性有机化合物暴露的调查中必须予以考虑：1）有利于室外挥发性有机化合物积累的时期会对室内值有很大贡献；2）对于没有个别化合物室内来源的家庭，室内值由挥发性有机化合物的室外值驱动。主要结果与之前的TEAM研究并不矛盾，之前的研究表明，当存在特定挥发性有机化合物的室内来源时，个人暴露和微环境暴露主要受室内因素影响。未来将外部暴露值与人体呼吸分析研究进行比较时，必须进行设计，以便更紧密地反映与特定挥发性有机化合物消除半衰期相关的时间间隔。
