| mercury exposure in humboldt (spheniscus humboldti) and chinstrap (pygoscelis antarcticus) penguins throughout the chilean coast and antarctica. | penguins are reliable sentinels for environmental assessments of mercury (hg) due to their longevity, abundance, high trophic level, and relatively small foraging areas. we analyzed hg concentrations from blood and feathers of adult humboldt penguins (spheniscus humboldti) and feathers of chinstrap penguins (pygoscelis antarcticus) from different reproductive colonies with variable degrees of urbanization and industrialization along the chilean and antarctic coasts. we evaluated hg concentration ... | 2018 | 29725722 |
