Abstract

The objectives of this study were to determine VOC emission signatures by PTR-MS, and to explore the correlations between PTR-MS measurements and acceptability index levels previously measured by human subjects. Emissions from nine materials, the same ones previously studied by DTU and SBi to investigate human exposure-response relationships in terms of acceptability index, were measured individually in a 50-L-small-scale chamber with similar area-specific airflow rates as in the test with human subjects. Chamber air was sampled by PTR-MS to determine emission signatures followed by sorbent tube sampling for identifying major VOCs emitted from each material and for comparing with PTR-MS emission signatures. The study focused on the analysis of the concentration level and composition of emitted VOCs causing acceptability differences among the tested materials. Results show high correlation between PTR-MS measurements and acceptability when the sum of individual VOC odor indices was used to represent the emission strength by PTR-MS.
