No evidence of microplastic ingestion in emperor penguin chicks (Aptenodytes forsteri) from the Atka Bay colony (Dronning Maud Land, Antarctica)

Environmental contamination and climate change in Antarctic ecosystems: an updated overview

“…[149][150][151] Although these studies seem to suggest trophic transfer and possible biomagnication of MPs along food webs, Sfriso et al 146 found 3-5 times higher concentrations in lter-feeder bivalves and benthic grazers than in omnivorous or predatory species of Antarctic invertebrates. Furthermore, Leistenschneider et al 152 found that none of the 85 particles ingested by chicks of the emperor penguin (Aptenodytes forsteri, the only penguin species breeding around Antarctica during the…”

Furthermore, Leistenschneider et al 152 found that none of the 85 particles ingested by chicks of the emperor penguin (Aptenodytes forsteri, the only penguin species breeding around Antarctica during the austral winter) collected in Queen Maud Land were MPs, and the synthetic bers found were due to contamination during the analysis and processing of the samples. Also, Garcia-Garin et al 153 found that the bers and fragments found in scats of male Antarctic fur seals (Arctocephalus gazella) collected at Deception Island (a hotspot of tourism and scientic activities in Antarctica) were silicate minerals and chitin bers, and not MPs.…”
