VOC concentrations in the belly space were measured during four sampling events. Adjusted belly concentrations were compared to average adjusted indoor concentrations (Table 3). Here the fractional differences were positive for all compounds. For a number of VOCs, these differences were substantial (2-butanone, less volatile aldehydes, alkane hyrdrocarbons, and aromatic hydrocarbons except styrene).
