AB  - The ecological features of the Ross Sea trophic web are peculiar and different 
      from other polar food webs, with respect to the use of habitat and species 
      interactions; due to its ecosystem integrity, it is the world's largest Marine 
      Protected Area, established in 2016. Polar organisms are reported to 
      bioaccumulate lipophilic contaminant, viz persistent organic pollutants (POPs). 
      Legacy POPs and flame retardants (polybrominated diphenyl ethers, PBDEs) were 
      studied in key species of the Ross Sea (Euphausia superba, Pleuragramma 
      antarctica) and their predators (Dissostichus mawsoni, Pygoscelis adeliae, 
      Aptenodytes forsteri, Catharacta maccormicki, Leptonychotes weddellii). 
      Gaschromatography revealed the presence of PCBs, HCB, DDTs, PBDEs in most of the 
      samples; HCHs, dieldrin, Eldrin, non-ortho PCBs, PCDDs, PCDFs were detected only 
      in some species. The average  summation operatorPBDEs was 0.19-1.35 pg/g wet wt in the key-species 
      and one-two order of magnitude higher in the predators. Penguins and skuas from 
      an area where a long-term field camp is located showed higher BDE concentrations. 
      The SigmaDDTs was higher in the Antarctic toothfish (20 +/- 6.73 ng/g wet wt) and in 
      the South Polar skua (5.911 +/- 3.425 ng/g wet wt). The TEQs were evaluated and the 
      highest concentration was found in the Weddell seal, due to PCB169, 
      1,2,3,4,7,8-HxCDF, and 2,3,4,6,7,8-HxCDF. There was no significant relationship 
      between the trophic level and the POP concentrations. Although low 
      concentrations, organisms of the Ross Sea trophic web should be further studied: 
      lack of information on some ecotoxicological features and human impacts including 
      global change may distress the ecosystem with unpredictable effects.
