建筑相关的健康影响或症状（BRS），也被称为病态建筑综合征（SBS），是一种尚未得到很好理解的现象。在这项研究中，从51个房间与BRS和34个控制室的空气样品收集在多吸附管和分析的非目标的方法，使用全面的二维气相色谱和高分辨率质谱技术。利用多元统计（主成分分析（PCA）和偏最小二乘法（PLS））对收集到的大量数据进行分析，结果显示，在经历过BRS的房间中，石油化学物质和塑料中的化学物质含量丰富，而在没有经历过BRS的房间中，香料和芳香化合物含量丰富。在石化产品中，苯和2-丁氧基乙醇在人们经历BRS的房间中含量较高。柠檬烯的水平有时在报告的气味阈值范围内，类似地，在人们没有经历BRS的房间的室内空气中发现了更高浓度的3-$>烯和β-月桂烯。不能排除这些化合物可能影响了空气质量。然而，空气浓度的总体变化很大，不可能准确预测特定房间的空气是否会导致BRS。
Building related health effects or symptoms (BRS), known also as sick-building syndrome (SBS), are a phenomenon that is not well understood. In this study, air samples from 51 rooms associated with BRS and 34 control rooms were collected on multi-sorbent tubes and analyzed by a non-target approach using comprehensive two-dimensional gas chromatography and high-resolution mass spectrometry techniques. The large amount of data gathered was analyzed using multivariate statistics (principle component analysis (PCA) and partial least squares (PLS)).This new analysis approach revealed that in rooms where people experienced BRS, petrochemicals and chemicals emitted from plastics were abundant, whereas in rooms where people did not experience BRS, flavor and fragrance compounds were abundant. Among the petrochemicals benzene and 2-butoxyethanol were found in higher levels in rooms where people experienced BRS. The levels of limonene were sometimes in the range of reported odor thresholds, and similarly 3-carene and beta-myrcene were found in higher concentrations in indoor air of rooms where people did not experience BRS. It cannot be ruled out that these compounds may have influenced the perceived air quality. However, the overall variability in air concentrations was large and it was not possible to accurately predict if the air in a particular room could cause BRS or not.
