AB  - The objective of this study was to assess the levels of persistent organic 
      pollutants (POPs) and mercury (T-Hg) in the blubber and skin, respectively, of 
      the free-ranging bottlenose dolphins, Tursiops truncatus, from the 
      Normanno-Breton Gulf, one of the largest identified coastal population in Europe. 
      Among all the POPs analysed in this study, the  summation operatorNDL-PCBs were the most abundant 
      compounds found in the blubber (mean: 1.33 x 10(5)-0.65 x 10(5) ng.g(-1) lipid 
      weight (lw) for males and females respectively), followed by  summation operatorDDX 
      (1.11 x 10(4)-4.67 x 10(3) ng.g(-1) lw) >  summation operatorDL-PCBs 
      (8.06 x 10(3)-2.62 x 10(3)ng.g(-1) lw) >  summation operatorPBDEs 
      (1.95 x 10(3)-0.64 x 10(3)ng.g(-1) lw) > dieldrin 
      (1.86 x 10(3)-0.18 x 10(3) ng.g(-1) lw) >  summation operatorendosulfan (405-62 ng.g(-1) lw) > HCB 
      (86-52 ng.g(-1) lw) >  summation operatorHCHs (47-60 ng.g(-1) lw) >  summation operatorchlordane (24-0.97 ng.g(-1) 
      lw) >  summation operatorPCDFs (0.3-0.1 ng.g(-1) lw) >  summation operatorPCDDs (0.06-0.05 ng.g(-1) lw). The T-Hg 
      concentrations were highly variable between individuals (2.45 x 10(3) ng.g(-1) to 
      21.3 x 10(3) ng.g(-1) dry weight, dw). The reported concentrations are among the 
      highest reported for cetaceans. We strongly recommend that the Normanno-Breton 
      Gulf be a special area of conservation (cSAC) candidate because it contains the 
      last large European population of bottlenose dolphins (rare or threatened within 
      a European context) designated under the EC Habitats Directive.
