TI  - Fine-scale spatial variation of persistent organic pollutants in bottlenose 
      dolphins (Tursiops truncatus) in Biscayne Bay, Florida.
PG  - 7222-8
AB  - Bottlenose dolphins (Tursiops truncatus) are long-term residents and apex 
      predators in southeast U.S. estuaries and are vulnerable to bioaccumulation of 
      persistent organic pollutants (POPs). Dart biopsy samples were collected from 45 
      dolphins in Biscayne Bay (Miami, FL), 34 of which were matched using fin markings 
      to a photo identification catalogue. Blubber samples were analyzed for 73 
      polychlorinated biphenyl (PCB) congeners, six polybrominated diphenyl ether 
      (PBDE) congeners, and organochlorine pesticides including 
      dichloro-diphenyl-trichloroethane (DDT) and metabolites, chlordanes, and 
      dieldrin. Total PCBs (sigma 73PCBs) were present in the highest concentrations 
      and were 5 times higher in males with sighting histories in the northern, 
      metropolitan area of Biscayne Bay than males with sighting histories in the 
      southern, more rural area [geometric mean: 43.3 (95% confidence interval: 
      28.0-66.9) vs 8.6 (6.3-11.9) microg/g wet mass, respectively]. All compound 
      classes had higher concentrations in northern animals than southern. The 
      differences in POP concentrations found on this small geographic scale 
      demonstrate that differential habitat use can strongly influence pollutant 
      concentrations and should be considered when interpreting bottlenose dolphin POP 
      data. The PCB concentrations in northern Bay dolphins are high as compared to 
      other studies of estuarine dolphins and may place these animals at risk of 
      reproductive failure and decreased immune function.
