Microplastic Found in Almost All Antarctic Seabirds

Scientists have detected microplastic in almost all seabirds in Antarctica. They analyzed 1100 samples, including the contents of the stomachs, thyroid glands, guano, and regurgitated undigested food particles. A total of 3526 plastic particles were extracted, with at least one found in 90% of Arctic samples and 97% of Antarctic samples. One bird had a maximum of 36 particles in its body. The ingestion of plastic particles by birds can lead to blockages in their digestive tracts, toxic effects, oxidative stress, and trigger immune reactions.
