文摘

Methoxylated polybrominated diphenyl ethers (MeO-PBDEs) and hydroxylated PBDEs (OH-PBDEs) have recentlybeen identified in fish and wildlife from the Baltic Sea.Both OH-PBDEs and MeO-PBDEs are known natural products,while OH-PBDEs also may be metabolites of PBDEs. Theaim of the present study was to determine if the red macroalgaCeramium tenuicorne could be a source for MeO- and OH-PBDEs in the Baltic environment. Blue mussels (Mytilusedulis) from the same area were also investigated for theircontent of MeO- and OH-PBDEs. Seven OH-PBDEs andfour MeO-PBDEs were present both in the red macroalgaand the blue mussels. The mussels also contained amonochlorinated OH-tetraBDE. One of the compounds,6-methoxy-2,2',3,4,4',5-hexabromodiphenyl ether, has neverbeen reported to occur in the environment. The identificationwas based on comparison of relative retention timeswith reference standards, on two gas chromatographiccolumns of different polarities, together with comparisonsof full-scan electron capture negative ionization (ECNI)and electron ionization (EI) mass spectra. It is shown that MeO-PBDEs and OH-PBDEs are present in algae, but at thisstage it could not be confirmed if the compounds are producedby the alga itself or by its associated microflora and/ormicrofauna.
