벽지에서 방출되는 TVOCs와 냄새원인물질 분석
Abstract
In this study, the TVOCs and odor active compounds emitted from 3 PVC and 5 natural wallpapers were analyzed. The emitted odor intensities and characteristics of the wallpapers were estimated using air dilution sensory and direct olfactory methods. The emissions of TVOCs were measured using the SPME-cryogenic emission test method, which was modified from the RAL-GZ 479 method, which is used in Germany to evaluate the quality of wallpapers. It was found that there was no significant correlation between the emissions of TVOCs and the odor concentration. However, a correlation (0.57) was found between the emitted VOCs and the odor concentration of the low molecular weight compounds, which have strong volatilities, ranging from n-C6 to n-C10. For all 8 wallpapers, vinegar like odor was commonly perceived, with acetic acid identified as the main odor active compound withinthe odor. Benzaldehyde and esters, such as ethyl acrylate and n-butyl acrylate, were identified as odor active compounds, which were expressed as having rubber like smells by the panelists. These results indicate that odor should be included as a domestic regulation for the pollutants emitted from building materials. The identification of odor active compounds emitted from building materials could be useful in the production of eco-environment products.
