Polybrominated diphenyl ethers (PBDEs) are brominated flame retardants (BFRs) widely used in plastics. Due to their toxicity and persistence, their industrial production is to be eliminated under the Stockholm Convention.
Contamination from PBDEs is widespread in the environment, including in sediments. In order to determine PBDEs in sediments, they need to be separated from a large amount of interferences co-extracted during sample preparation. GC-MS and GC-MS/MS were evaluated for this purpose.
