Accumulation of PBDEs and MeO-PBDEs in notothenioid fish from the South Shetland Islands, Antarctica: An interspecies comparative study

Concentrations of polybrominated diphenyl ethers (PBDEs) and methoxylated (MeO-PBDEs); are reported in specimens fish notothenioids Chaenocephalus aceratus (SSI), Trematomus bernacchii (ERN), Nototheniops nudifrons (NOD) from the South Shetland Islands, Antarctica. Significant differences accumulation 2?-MeO-BDE-68 6-MeO-BDE-47 were detected among analysed species. MeO-BDEs significantly higher SSI (11.7, 8.6, 14.1 ng g?1 lw) than NOD (1.63, 1.63, 3.0 muscle, liver, gill, respectively. Feeding ecology traits explain patterns MeO-PBDEs. has a feeding activity with broader diet, followed by ERN, whereas is benthic/sedentary narrower diet. The PBDEs was neither species-, nor tissue-specific. current study expands knowledge concerning MeO-PBDEs Antarctic marine supports importance species-specificity
