Impact of indoor surface material on perceived air quality

• The indoor VOC and odor emissions were investigated in a test chamber.
• The aimed material combinations' impact on air quality was reported.
• The VOC mixture affects air quality while individual VOCs are below their odor thresholds.
• Chemical assessment has to be done simultaneously with sensory assessment.
• The positive effects of selected material combinations were recognized.

The material combination impact on perceived indoor air quality for various surface interior materials is presented in this paper. The chemical analysis and sensory assessments identifies health adverse of indoor air pollutants (TVOCs). In this study, emissions and odors from different common indoor surface materials were investigated in glass test chamber under standardized conditions. Chemical measurements (TVOC concentration) and sensory assessments (odor intensity, air acceptability) were done after building materials exposure to standardized conditions. The results of the chemical and sensory assessment of individual materials and their combinations are compared and discussed within the paper. The using possibility of individual material surface sorption ability was investigated. The knowledge of targeted sorption effects can be used in the interior design phase. The results demonstrate the various sorption abilities of various indoor materials as well as the various sorption abilities of the same indoor material in various combinations.
