No evidence of microplastic ingestion in emperor penguin chicks (Aptenodytes forsteri) from the Atka Bay colony (Dronning Maud Land, Antarctica)
Microplastic (<5 mm; MP) pollution has been an emerging threat for marine ecosystems around the globe with increas-ing evidence that even the world's most remote areas, including Antarctica, are no longer unaffected. Few studies how-ever, have examined MP in Antarctic biota, and especially t...

Microplastic (<5 mm; MP) pollution has been an emerging threat for marine ecosystems around the globe with increas-ing evidence that even the world's most remote areas, including Antarctica, are no longer unaffected.

The aim of this study was to investigate, for the first time, the occurrence of MP in the emperor penguin (Aptenodytes forsteri), the only penguin species breeding around Antarctica during the austral winter, and an endemic apex predator in the Southern Ocean.
