Adsorptive wall materials of four different compositions were exposed to this gas mixture, consisting of 1-pentanol, hexanal, butyl acetate and n-decane. Aim of this study was to scrutinize the ability of these samples to reduce the concentration of the supplied gas. This capacity is expressed in the sorption flux F or area specific adsorption rate respectively. The test was performed referring to a draft of ISO 16000-24.

Size resolved sampling of the emitted particles was done with a 13 stage (30 nm to 10 µm) low pressure cascade impactor. The sampled particles were analysed for their chemical composition by thermal extraction (vaporization at 290°C) followed by GC-MS analysis. High boiling cyclic siloxanes (D10 to D16) were detected as constituents of UFP from laser printers. In comparison to measurements in 2008, aliphatic long-chain alkanes (C22 to C34) were detected additionally as chemical constituents of UFP from most of the tested printers and their amounts were higher than for cyclic siloxanes. Printers of one manufacturer showed very low UPF emissions compared to the other manufacturers.

To ensure good indoor air quality contamination by volatile organic compounds (VOC) should be minimised. The aim of the project is the reduction of unsaturated aldehydes which can emit from oriented Strand boards (OSB): These aldehydes have an impact on the health based evaluation of emissions from products for indoor use according to the AgBB (Ausschuss zur gesundheitlichen Bewertung von Bauprodukten, Committee for Health Evaluation of Building Products) scheine (AgBB 2010). The model OSB were produced in a pilot plant using well known raw materials (Pinus sylvestris at different trunk heights) under using various processing parameters (Wilke et al. 2011). OSB emit predominantly monoterpenes and aldehydes. Aldehydes are oxidation products of fatty acids in wood. The conditions which affect the oxidation process are the fatty acid concentration and composition, the oxygen content, the sample surface and the presence of compounds which indicate, inhibit or stop the oxidation respectively. The oxidation rate rises with an increasing number of double bounds in the fatty acid, e.g. the oxidation rate between oleic, linoleic and linolenic acid correspond to 1:12:24. One of the most important products of fatty acid oxidation is hexanal. It is generated during the oxidation of linoleic acid. This study shows a direct correlation between aldehyde emission and oxidation, hexanal can be used as an indicator for oxidation.

The analysis was performed with thermal desorption in combination with gas chromatography and mass spectrometry. Emissions of organic acids were determined. The damage risk of volatile organic compounds, e.g. organic acids as acetic acid, propanoic acid, hexanoic acid and octanoic acid was investigated on model glasses in climate chambers. After exposure the surface of the most sensitive samples was damaged. Based on emission measurements in exhibit cases of the former museum "Grünes Gewölbe in the Albertinum" in Dresden, Germany, the atmospheric conditions inside the show cases were determined. It can be shown that the atmospheric conditions inside the cases endanger the glass and enamel objects of art especially in show cases with low air exchange rates. Materials with high emission rates of organic acids should not be in direct contact with medieval glass for a long time and should not be used in exhibit cases. Acid emissions, especially acetic acid plays an important role during investigation of different materials for show cases and can be determined by direct thermal desorption.

T1 - Reproducibly emitting reference material for quality assurance/quality control of emission test chamber measurements N2 - Volatile Organic Compounds (VOC) are ubiquitous in the indoor air, since they emit from materials used indoors. Investigations of these materials are mostly carried out in test chambers under controlled climatic conditions. Quality control of these test chamber measurements is important but there is a lack of commercially available homogenous reference materials as required for round robin tests or quality assurance of laboratories. The approach of the present study is the impregnation of a supporting material with VOC, which are reproducibly released in measurable chamber air concentrations under standardised test conditions. A polymer made of Thermoplastic Polyurethane (TPU) was chosen as carrier material. It was impregnated with the VOC trimethyl pentanediol isobutyrat (texanol).

Therefore Chemical emissions from wood have an influence on the indoor air quality. A research project financed by the Federal Environmental Agency focused on VOC emissions from oriented Strand boards (OSB) and also from plywood made from pine and spruce (Wilke et al., 2011a). This paper shows results of the plywood testing because only little information is available about plywood emission behaviour and its impact on indoor air quality.
