For determining VOCs emitted from bioeffluents, the indoor air collected in the classrooms of the elementary schools and a college were analyzed. As representative VOCs from bioeffluents, 2-Ethyl-1-Hexanol (2E1H), Nonanal, Decanal, Nonane, Undecane, and Dodecane were identified and quantified. The concentrations of 2E1H, Nonanal, Decanal, Nonane, Undecane, Dodecane in occupied classrooms were higher than those in unoccupied classrooms. There was a higher correlation between the concentration of 2E1H and the reciprocal of the ventilation rate per person under the occupied conditions. While the higher correlation was also obtained between the concentration of 2E1H and the in-door CO2 concentration in the classrooms, the concentrations of Nonanal, Decanal, Nonane, Undecane, and Dodecane did not correlate with the ventilation rate nor CO2. The 2E1H concentration could be an useful index of the air pollution by human bioeffluents.
