AB  - Bottlenose dolphins (Tursiops truncatus) are apex predators in coastal 
      southeastern U.S. waters; as such they are indicators of persistent organic 
      pollutants (POPs) in coastal ecosystems. POP concentrations measured in a 
      dolphin's blubber are influenced by a number of factors, including the animal's 
      sex and ranging pattern in relation to POP point sources. This study examined POP 
      concentrations measured in bottlenose dolphin blubber samples (n=102) from the 
      Georgia, USA coast in relation to individual ranging patterns and specifically, 
      distance of sightings from a polychlorinated biphenyl (PCB) point source near 
      Brunswick, Georgia. Dolphin ranging patterns were determined based upon 5years of 
      photo-identification data from two field sites approximately 40km apart: (1) the 
      Brunswick field site, which included the Turtle/Brunswick River Estuary (TBRE), 
      and (2) the Sapelo field site, which included the Sapelo Island National 
      Estuarine Research Reserve (SINERR). Dolphins were categorized into one of three 
      ranging patterns from photo-identification data. Individuals with sighting 
      histories exclusively within one of the defined field sites were considered to 
      have either Brunswick or Sapelo ranging patterns. Individuals sighted in both 
      field sites were classified as having a Mixed ranging pattern. Brunswick males 
      had the highest concentrations of PCBs reported for any marine mammal. The 
      pattern of PCB congeners was consistent with Aroclor 1268, a highly chlorinated 
      PCB mixture associated with a Superfund site in Brunswick. PCB levels in Sapelo 
      males were lower than in Brunswick males, but comparable to the highest levels 
      measured in other dolphin populations along the southeastern U.S. Female dolphins 
      had higher Aroclor 1268 proportions than males, suggesting that the highly 
      chlorinated congeners associated with Aroclor 1268 may not be offloaded through 
      parturition and lactation, as easily as less halogenated POPs. Individuals 
      sighted farther from the Superfund point source had lower Aroclor 1268 
      proportions.
