Summary

Emissions and odors from different common indoor materials were investigated within this study. The measurements were conducted in test chamber under standardized conditions (23°C, 50%) and different ventilation rates. Ventilation rates were determined for different categories of indoor environmental duality level. The study of interior materials impact on perceived air quality under standardized ventilation rate (0.5 1/h) has shown that common final surface finishing’s are significant sources of indoor odors and according to European standards fall within the category of non low-polluting materials. Therefore the required ventilation rate was determined for non-low polluting model room (3.2 x 2.2 x 2.4 m). Chemical measurements (TVOC) and sensory assessments (odor intensity, perceived air quality) were done after 3th day of building materials exposure to standardized conditions. Active sampling of VOCs was performed by using a pump (Aircheck 2000) with air flow rate of 400 ml/min on charcoal tubes ORBO 32S (Supelco) during 24 hours. The absorbed VOCs were analyzed by gas chromatography (GC Varian 3 300) after extraction into CS2. An untrained sensory panel of 20 subjects assessed odor intensity and perceived air quality. The increased ventilation rate does not evoke adequate response in subjective sensory assessment as well in decreasing of odor indicator level. The source control appears as more effective then ineffective increasing of air change level. The impact of ventilation rate on perceived indoor air quality pollution from selected building materials will be discussed within the paper.
