TI  - Polychlorinated biphenyls and toxaphene in preferred prey fish of coastal 
      southeastern U.S. bottlenose dolphins (Tursiops truncatus).

AB  - Legacy organochlorine (OC) contaminants continue to pose a potential risk to 
      ecological and human health in coastal aquatic ecosystems of the southeastern 
      United States. Polychlorinated biphenyls (PCBs) and toxaphene (TOX) were analyzed 
      by gas chromatography with electron capture detection and negative chemical 
      ionization mass spectrometry in 77 composites of four inshore fish species 
      commonly preyed upon by bottlenose dolphins (Tursiops truncatus) from estuaries 
      near Savannah, Georgia (SAV), Brunswick, Georgia (BRN), and Jacksonville, Florida 
      (JAX), USA. Whereas seasonal and species-specific differences were minimal, 
      differences among mean total PCB concentrations (sigmaPCBs) by estuary (42.0 +/- 
      48.3, 1.59 +/- 1.24, and 0.281 +/- 0.075 microg/g lipid for BRN, JAX, and SAV, 
      respectively) were highly significant. This estuary-specific trend also held true 
      for mean total toxaphene concentrations (sigmaTOX): 49 +/- 100 (BRN), 1.2 +/- 
      0.52 (JAX), and 0.40 +/- 0.19 microg/g lipid (SAV). Congener profiles of PCBs 
      also were found to be significantly different among estuaries, with BRN and (to a 
      lesser extent) JAX samples enriched with highly chlorinated homologs associated 
      with Aroclor 1268, a legacy OC linked to a historical point source in Brunswick. 
      The observed spatial heterogeneity in OC concentrations and PCB congener profiles 
      suggests that contaminated fish from Brunswick pose the greatest risk to 
      ecological and human health via biomagnification and seafood consumption; highly 
      chlorinated PCBs (and possibly toxaphene) are transported in a southerly, 
      alongshore direction; and the uniqueness of Aroclor 1268 underscores its utility 
      as a signature proxy in future regional ecotoxicological studies.
