TI  - Seabird guano is an efficient conveyer of persistent organic pollutants (POPs) to 
      Arctic lake ecosystems.

AB  - Migratory seabirds have been linked to localized "hotspots" of contamination in 
      remote Arctic lakes. One of these lakes is Lake Ellasjoen on Bjornoya in the 
      Barents Sea. Here we provide quantitative evidence demonstrating that even 
      relatively small populations of certain seabird species can lead to major impacts 
      for ecosystems. In the present example, seabird guano accounts for approximately 
      14% of the contaminant inventory of the Lake Ellasjoen catchment area, 
      approximately 80% of the contaminant inventory of the lake itself, and is 
      approximately thirty times more efficient as a contaminant transport pathway 
      compared to atmospheric long-range transport. We have further shown that this 
      biological transport mechanism is an important contaminant exposure route for 
      ecosystems, responsible for POPs levels in freshwater fish that are an order of 
      magnitude higher than those in Arctic top predators. Given the worldwide presence 
      of seabird colonies in coastal marine areas where resources are also harvested by 
      humans, this biological transport pathway may be a greater source of dietary 
      contamination than is currently recognized with consequent risks for human 
      health.
