Abstract

Graphical abstract: Highlights: POPs novel flame retardants in biota from Antarctica. Positive relationships of PCBs, PBDEs and novel flame retardants. Bioaccumulation along trophic levels. Abstract: Persistent organic pollutants (POPs), including polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), are frequently detected in biota from Antarctica, whereas no data are available for their replacements, such as novel flame retardants (N-FRs). This study presented the occurrence of several N-FRs, PBDEs, and PCBs in tissue samples of an Antarctic rock cod ( Trematomus bernacchii ), a young gentoo penguin ( Pygoscelis papua ), and a brown skua ( Stercorarius antarcticus ) collected from King George Island. The total concentrations of N-FRs (ΣN-FRs; mean: 931 pg/g dry weight (dw)) were comparable to PBDEs (Σ8 PBDEs; 681 pg/g dw), which were much lower than PCBs (ΣDL-PCBs; 12, 800 pg/g dw). Overall, skua contained two to three orders of magnitude higher contamination than penguin and fish. In the future, more attention should be focused on the fate of N-FRs in Antarctica, where usages have increased since PBDEs were banned. To our knowledge, this is the first report of N-FRs in biota from Antarctica.
