Chemical pollutant emission from a sleeping person and a carpet

eople spend nearly one-third of their time sleeping in bedrooms. Human emissions (bioeffluents) are one of the main sources of pollution in bedrooms. Carbon dioxide emitted by sleeping people is used to estimate ventilation efficiency and therefore regarded as an indicator of bedroom air quality (Maula et al., 2017). Other human emissions have been studied in healthy (Tang et al., 2016) or sick individuals (Miekisch et al., 2004), but mainly when awake. Studies focusing on bioeffluents emitted by humans during sleep are sporadic. The present work is a pilot study in which human emissions during sleep were monitored in a climate chamber. Meanwhile, chemicals emitted from the carpet that was used during sleep were also analyzed. The study is a part of a larger project ICHEAR aiming at examining the emission rates from humans and their transformations in indoor environments.
