Human chemical signature - Investigating the influence of human presence and selected activities on concentrations of airborne constituents


Studies have suggested that the presence of human beings in an enclosed environment can significantly impact the quality of the air. For example, emissions from exhaled breath and skin influence the concentrations of certain airborne volatile organic compounds (VOC). This influence increases considerably when humans perform different activities of daily living, such as eating and drinking or simply using toiletries. To understand the influence of these parameters on the concentrations of selected airborne constituents, a study was performed under simulated residential conditions (0.5 h-1) in an environmentally controlled exposure room (indoor air quality room; IAQ room).
