T1 - Emission of Flame Retardants from Consumer Products and Building Materials N2 - The emission levels of high boiling brominated (BFR) and phosphoric (POC) flame retardants (FR) in different materials were examined. For the determination of the emission rate the tests were done in different emission test chambers and cells under standard conditions (23 C, 50% RH and fixed area specific air flow rates). Selected products, e.g. printed circuit boards, were investigated at elevated temperature (e.g. 60 C) to simulate working conditions. Applied analytical techniques for the air samples adsorbed on polyurethane foam (PUF) are soxhlet and ultrasonic extraction. Different conditions were used to analyse the FR via GC-MS. Based on the first results it could be demonstrated that the emission depends on material density and surface condition. The concentrations over time obtained for tris(3-chloropropyl)-phosphate, e.g., from emission test chamber and cell show a good correlation, partly the measured concentration are different. Sampling at elevated temperature gives higher concentrations.

T1 - Formaldehyde emissions from wooden toys: Comparison of different measurement methods and assessment of exposure N2 - Formaldehyde is considered as carcinogenic and is emitted from particleboards and plywood used in toy manufacturing. Currently, the flask method is frequently used in Europe for market surveillance purposes to assess formaldehyde release from toys, but its concordance to Levels measured in emission test chambers is poor. Surveillance laboratories are unable to afford laborious and expensive emission chamber testing to comply with a new amendment of the European Toy Directive; they need an alternative method that can provide reliable results. Therefore, the application of miniaturised emission test chambers was tested. Comparisons between a 1 m3 emission test chamber and 44 mL microchambers with two particleboards over 28 days and between a 24 L desiccator chamber and the microchambers with three puzzle samples over 10 days resulted in a correlation coefficient r2 of 0.834 for formaldehyde at steady state. The correlation between the results obtained in microchambers vs. flask showed a high variability over 10 samples (r2: 0.145), thereby demonstrating the error-proneness of the flask method in comparison to methods carried out under ambient parameters. An exposure assessment was also performed for three toy puzzles: indoor formaldehyde concentrations caused by puzzles were not negligible (up to 8 µg/m3), especially when more conservative exposure scenarios were considered.

However, the chemical composition of emitted particles has been less extensively investigated. In this study, we therefore focused on the chemical composition of particles emitted from 3D printing. The measurements were conducted in a 1 m³ emission test chamber. Emitted particles were sampled by a 13-stage low-pressure cascade impactor onto aluminum foils and then analyzed by TD-GC/MS to identify their organic compounds. Nine commercial filaments made from basic polymers such as Acrylonitrile Butadiene Styrene (ABS), Acrylonitrile Styrene Acrylate (ASA), Polycarbonate (PC), Poly(methyl methacrylate) (PMMA), Nylon, High Performance Polystyrene (HIPS) and a copper-filled Polylactide (PLA) were investigated. The results show that the organic components of the particles are primarily plastic additives such as plasticizer, antioxidant agents, lubricants, UV-absorbers and UV-stabilizers from the filaments.

In Germany and other European countries, OSBs are mainly produced from pine wood (Pinus sylvestris). In response to complaints about the odour and irritation of mucous membranes in connection with the use of OSBs, samples of OSBs were bought from do-it-yourself stores to test their volatile organic compound (VOC) emissions by using emission test chambers. The boards emitted predominantly monoterpenes, aldehydes, acids and acetone. Aldehydes are generated during the production process by the oxidation of unsaturated fatty acids such as linoleic acid. Pine wood, compared with other wood species, contains more unsaturated fatty acids. Of the six acquired OSBs, four boards from three manufacturers would not meet the requirements of the German AgBB (Ausschuss zur gesundheitlichen Bewertung von Bauprodukten, Committee for Health Evaluation of Building Products), mainly because of the emissions of unsaturated aldehydes. These compounds have low LCI values (lowest concentration of interest) and are therefore problematic substances based on a health-related evaluation of building products according to the AgBB scheme.

A1 - Kalus, Sabine A1 - Horn, Wolfgang T1 - Determination of formic and acetic acids in air N2 - Formic and acetic acids are often responsible for damage of cultural objects, e. g. glass and metal corrosion or changing and fading of colours. Museums all around the world are equipped with different show cases. Display cases should protect cultural objects from dust as well as from mechanical damage. Several construction materials which are used for display cases, including wood, glue and coatings, are possible sources of very volatile organic compounds (VVOCs), volatile organic compounds (VOCs) and semi volatile organic compounds (SVOCs). These construction products can emit formic and acetic acids into the indoor or display case air. Modern display cases with small air change rates can cause higher concentrations of formic and acetic acids if any source is installed in the display case (Salthammer and Uhde, 2009). To minimize the risk of damage emissions from building products must be quantified. There is a need for a method for identification and quantification of acetic and formic acid. Some possibilities for the identification of acetic acid exist. The quantification of acetic acid for example after sampling on TENAX® or CARBOTRAP and thermal desorption-GC in accordance with ISO 16000-6 and ISO 16017-1 results in very low recovery rates. A new method should be stabile, robust, reproducible and comparable, with an easy local sampling and determination in laboratories. Miniaturised emission test chambers and model display cases were used to study the recovery rates.

The amounts of volatile organic compounds (VOC) which emit from products in emission test Chambers are used to evaluate these products. Typically labelling procedures for construction products are based on emission test chamber measurements. This performance should be verified. Possibly this can be performed due to testing of one material at different laboratories within a round robin test. Therefore it is necessary that a reference material exists which can be used for such round robin tests or as part of the quality management System to ensure comparable results. The different Statistical evaluation possibilities of a round robin test with a constant reference material for VOCs (volatile organic compounds) in emission test Chambers are the main focus of the presented paper.
