摘要

病态建筑综合症可能部分由挥发性有机化合物(VOCs)引起。一种假设是，总挥发性有机化合物浓度(TVOC)，而不是个别化合物，是导致该综合征的主要因素。根据采用气相色谱- fid技术的测量，估计出现症状的TVOC水平在1- 2mg / cm范围内。很少有测量数据可用于确定美国家庭和建筑物可能接近此量级TVOC水平的频率。然而，关于750个家庭和10个建筑物的个别挥发性有机化合物12小时平均值的数据可从EPA的TEAM研究(1981- 1988)中获得。为了确定从存储的GC/MS数据中获取TVOC值的可行性，初步研究表明，TVOC估计值可以获得令人满意的精度((+或-)30-60%)。因此，TVOC值是从TEAM研究中收集的大约2700个个人、室内和室外空气样本中计算出来的。

Total volatile organic concentrations in 2700 personal, indoor, and outdoor air samples collected in the US EPA team studies

Sick Building Syndrome may be caused in part by volatile organic compounds (VOCs). One hypothesis is that the total volatile organic concentration (TVOC), rather than individual compounds, is a main factor in the syndrome. The TVOC level at which symptoms occur has been estimated to be in the range of 1-2 mg/cum, based on measurements employing GC-FID techniques. Very few measured data are available to determine the frequency with which homes and buildings in the United States may approach TVOC levels of this magnitude. However, data on 12-hour average values of individual VOCs from 750 homes and 10 buildings were available from EPA's TEAM Studies (1981-88). An initial study to determine the feasibility of obtaining a TVOC value from stored GC/MS data showed that TVOC estimated could be obtained with satisfactory precision ((+ or -) 30-60%). Therefore TVOC values were calculated from about 2700 personal, indoor, and outdoor air samples collected in the TEAM Studies.

期刊介绍： The quality of the environment within buildings is a topic of major importance for public health. Indoor Air provides a location for reporting original research results in the broad area defined by the indoor environment of non-industrial buildings. An international journal with multidisciplinary content, Indoor Air publishes papers reflecting the broad categories of interest in this field: health effects; thermal comfort; monitoring and modelling; source characterization; ventilation and other environmental control techniques. The research results present the basic information to allow designers, building owners, and operators to provide a healthy and comfortable environment for building occupants, as well as giving medical practitioners information on how to deal with illnesses related to the indoor environment.
