Results and discussion

Any other information on results incl. tables

The determination of most of OPCs was successful using emission test chambers. Due to sink effects the determination of low volatile OPC such as RDP and BDP needs to be improved. Brominated flame retardants are quantifiable up to hexabrominated compounds using emission test chambers as a reference method. The emission of lower volatile compounds, e.g. HBCD, was strongly affected by sink effects. Emission of decaBDE was not quantifiable at all. Based on the results presented further investigations are required for an adequate risk assessment of flame retarded products and their contribution to the contamination of the indoor air environment. TCPP was found to be one of the most commonly used organophosphorus flame retardants in polyurethane foam applications. Depending on the sample type 0.012 to 140 µg m-2 h-1 was obtained for area-specific emission rates (SERa) for TCPP. PBDEs, for example, exhibited product-specific emission rates (SERu) between 0.1 and 14.2 ng unit-1 h-1 and SERa between 0.2 and 6.6 ng m-2 h-1. More data about the emission behaviour of FR are required with special regard to substance migration, aging and long-term emission in particular.
