| Abstract |
Experiments were conducted in a room-size test chamber to determine the sink effects of selected materials on indoor air concentrations of p-dichlorobenzene (PDCB). These effects might alter pollutant behavior from that predicted using simple indoor air quality models, by reducing the peak concentrations during source usage and by increasing the ventilation rates needed to reduce pollutant concentrations. Four experimental conditions were tested: empty chamber (painted gypsum wallboard), carpeting only, carpeting and drapes, and carpeting plus a full-size bed with a comforter. Chamber temperature and relative humidity were controlled; atmospheric pressure was monitored. Air exchange rates were monitored using the tracer-gas decay method. Chamber air, sampled at six minute intervals, was analyzed using a gas chromatograph. Sink effects were estimated by comparing decay curves fit to the tracer gas (SF6) and the PDCB concentrations. The influence of sink effects on indoor air concentrations was illustrated by estimating the ventilation rates required to reduce PDCB concentrations from 14 ppm to 2 ppm. |
