Correspondence between mercury and stable isotopes in high Arctic marine and terrestrial avian species from northwest Greenland

Birds are useful bioindicators of environmental contamination around the globe, but avian studies in the high Arctic have been primarily limited to a few abundant species. This study was designed to assess mercury (Hg) concentrations in both abundant and less-abundant marine and terrestrial avian species on breeding grounds in northwest Greenland using blood sampling. Twenty-four migratory avian species (n = 625) were sampled over a three-year...
