TI  - Persistent organic pollutants in the diet of harbor seals (Phoca vitulina) 
      inhabiting Puget Sound, Washington (USA), and the Strait of Georgia, British 
      Columbia (Canada): a food basket approach.
PG  - 2562-72
AB  - Harbor seals (Phoca vitulina) inhabiting Puget Sound (WA, USA) recently were 
      found to be seven times more contaminated with polychlorinated biphenyls (PCBs) 
      than those inhabiting the adjacent Strait of Georgia (BC, Canada). We carried out 
      a food basket approach to approximate realistic dietary exposures of both new 
      (e.g., polybrominated diphenyl ethers [PBDEs]) and legacy (e.g., 
      dichlorodiphenyltrichloroethane [DDT]) persistent organic pollutants (POPs) for 
      these harbor seals. Food basket homogenates, each consisting of over 200 
      individual prey items, were constructed using documented dietary preferences for 
      harbor seals in these basins, and analyzed for organochlorine pesticides, flame 
      retardants, and other persistent contaminants. Concentration rankings for the 
      major contaminant classes in the Puget Sound food basket were sigmaPCBs > 
      sigmaPBDEs > sigmaDDT, and for the Strait of Georgia food basket were sigmaPCBs > 
      sigmaDDT > sigmaPBDEs, highlighting the emergence of PBDEs as a significant 
      concern in the regional environment. Consistent with observations in harbor 
      seals, PCB concentrations in the Puget Sound food basket were seven times higher 
      than in its Strait of Georgia counterpart. Based on our food basket results, the 
      estimated daily intake of sigmaPCB toxic equivalents to dioxin by Puget Sound 
      harbor seals exceeds some wildlife consumption guidelines for PCBs. Our results 
      indicate that both legacy and new POPs present a health risk to these marine 
      mammals.
