Multivariate evaluation of VOCs in buildings where people with non-specific building-related symptoms perceive health problems and in buildings where they do not

Nine patients and 34 buildings (homes, various shops, offices, a library, hospital departments and sport centers) were included in that study. For every patient, two "non-problem" and two "problem" buildings were selected for sampling. A multivariate VOC model was used for the classification of "problem" and "non-problem" buildings .The result of the study showed a difference in the collected VOC data in the two types of buildings , with a systematic difference in the chemical composition of the air in the buildings.
