Brominated Flame Retardants (BFR) in the Nordic Environment

The present report describe the results of screening analyses of the occurrence of ”new” brominated flame retardants (BFRs) in environmental samples from the Nordic countries. The aim of the screening was to establish whether, and if then to what extent, the non-polybrominated diphenyl eters BFRs are present at detectable levels in the environment. If the substances subjected for screening are found in amounts which are potentially harmful for the environment this will be followed up on national level. The Nordic screening project is run by a project group with representatives from the National Environmental Research Institute, University of Aarhus Denmark, the Finnish Environment Institute, the Environment and Food Agency of Iceland, the Environment Agency of the Faroe Islands, the Norwegian Climate and Pollution Agency and the Swedish Environmental Protection Agency. The project is supported by the Nordic Chemicals Group and the Aquatic Ecosystems Group as well as the participating institutions. The chemical analyses have been carried out jointly by the Norwegian Institute for Air Research (NILU) and the Swedish Environmental Research Institute (IVL).

Results and discussion

All measured concentrations of individual substances are tabulated in Appendix 2. An overview of the detection frequencies, i.e. the fraction of samples where a substance was found in a concentration above the detection limit for different sample matrices, is given in Table 4.1. The detection limits varies as a consequence of variations in analytical methods, sample volumes/amounts and varying interferences in individual samples. As Table 4.1 is intended only as an overview, this variation is not taken into account here.
