      organic pollutants transported by breeding seabirds.

AB  - At Cape Vera, Devon Island (Nunavut, Canada), a colony of northern fulmars 
      (Fulmarus glacialis) concentrates and releases contaminants through their guano 
      to the environment. We determined whether persistent organic pollutants (POPs) 
      from seabirds were transferred to coastal food webs. Snow buntings (Plectrophenax 
      nivalis) were the most contaminated species, with  summation operatorPCB and  summation operatorDDT (mean: 168, 
      106 ng/g ww) concentrations surpassing environmental guidelines for protecting 
      wildlife. When examined collectively, PCB congeners and DDT in jewel lichen 
      (Xanthoria elegans) were lower in samples taken farther from the seabird colony, 
      and increased with increasing delta(15)N values. However, only concentrations of 
      p'p-DDE: summation operatorDDT and PCB-95 were significantly correlated inversely with distance 
      from the seabird cliffs. Linkages between marine-derived POPs and their 
      concentrations in terrestrial mammals were less clear. Our study provides novel 
      contaminant data for these species and supports biovector transport as a source 
      of organic contaminants to certain components of the terrestrial food web.
