AB  - Seabirds from remote regions are mainly exposed to environmental contaminants 
      from non-point contamination of their food webs. Pre-fledging seabird chicks are 
      fed by their parents with marine prey captured in the vicinity of breeding 
      colonies. Contaminant concentrations in tissues of pre-fledging chicks can thus 
      be mostly related to local dietary sources, and have the potential to unravel 
      spatial patterns of environmental contamination in marine ecosystems. Here, 
      mercury (Hg), 13 other trace elements, and 18 persistent organic pollutants 
      (POPs) were quantified in blood of chicks across four breeding locations that 
      encompass a large latitudinal range in the southern Indian Ocean (from 
      Antarctica, through subantarctic areas, to the subtropics), over a single 
      breeding season. Thirteen species of penguins, albatrosses and petrels were 
      studied, including endangered and near-threatened species, such as Amsterdam 
      albatrosses and emperor penguins. Blood Hg burdens varied widely between species, 
      with a factor of ~50 between the lowest and highest concentrations (mean +/- SD, 
      0.05 +/- 0.01 and 2.66 +/- 0.81 microg g(-1) dry weight, in thin-billed prions and 
      Amsterdam albatrosses, respectively). Species relying on Antarctic waters for 
      feeding had low Hg exposure. Concentrations of POPs were low in chicks, with the 
      exception of hexachlorobenzene. Contaminant concentrations were mainly explained 
      by species differences, but feeding habitat (inferred from delta(13)C values) and 
      chicks' body mass also contributed to explain variation. Collectively, our 
      findings call for further toxicological investigations in Amsterdam albatrosses 
      and small petrel species, because they were exposed to high and diverse sources 
      of contaminants, and in macaroni penguins, which specifically showed very high 
      selenium concentrations. CAPSULE: Seabird chicks from four distant sites in the 
      southern Indian Ocean had contrasted blood metallic and organic contaminant 
      patterns depending on species, feeding habitat and body mass.
