The present report has been generated on behalf of the Norwegian Climate and Pollution Agency (KLIF). The Institute for Environmental Studies (IVM) at the VU University Amsterdam, in collaboration with the Norwegian School of Veterinary Science (NVH) and the Norwegian Institute of Nature Research (NINA) has carried out a screening study on organophosphor flame retardants (PFR) in the Norwegian environment.

Any other information on results incl. tables

DBPP is expected accumulate in biota and sediment based on the estimated log Kow and log Koc. However, in the present study DBPP was not detected in any of the samples, except for 3 bird egg samples. The levels in these samples were high (3 -5.6 ng/g ww) as compared to the other egg samples (<0.01 ->0.84 ng/g ww). It is unclear what causes this bimodal distribution. In sediment all levels were below the LOD (< 0.05 -<0.33 ng/g dw). This may mean that the investigated water bodies are not contaminated (or only to a very low extent) with DBPP.

Results from an earlier study on Norwegian biota samples (fish, fish liver, fish muscle and seabird liver) showed similar results as all levels were below LOD (<0.05 -<1 ng/g ww), except for a seabird liver where 0.33 ng/g ww was observed (Evenset et al., 2009).

Applicant's summary and conclusion

Levels of DBPP measured in this study were in nearly all samples below the LOD, except in 3 bird samples.
Executive summary:

There is no information on the production and use of DBPP in Norway, Sweden, Denmark or Finland available, but DBPP has been used in Finland for hydrualic fluids and additives in the air transport industry.

Levels of DBPP measured in this study were in nearly all samples below the LOD, except in 3 bird samples.
