Műanyagdarabokat és műszálakat találtak a sarkvidéki jégben és hóban

Az északi-sarkvidéki hóban literenként 'csupán' 14 400 részecskét fedeztek fel a kutatók. A jégtáblákon pedig szabad szemmel is látható a szennyezés.

Már a jégben és a hóban is megjelentek a mikroműanyagok - írja az MTI a Reuters alapján.

Egy amerikai kutatók vezette tudóscsoport az Északnyugati átjáró jégtábláin gyűjtött jégmintákban talált műanyagdarabkákat, műszálakat.

Egy jégtörő fedélzetén haladtak át a Csendes-óceánt az Atlanti-óceánnal összekötő Északnyugati átjáróban és helikopteren repültek az úszó jégtáblákra, ahonnan jégmintákat gyűjtöttek.

A Kanada sarkvidéki területén lévő Lancaster-szorosban gyűjtött jégmintákban vették észre a szemmel jól látható műanyagdarabokat, ami azért volt meglepő, mert a tengerszorosról úgy vélték eddig, hogy viszonylag védett a tengeráramlatok által sodort műanyagszeméttől.

Amikor megnéztük szabad szemmel közelről a mintákat, nagyon jól látható volt, hogy szennyezett, amikor a megfelelő eszközökkel megvizsgáltuk, olyan volt, mintha gyomron ütöttek volna

– mondta Jacob Strock, a Rhode Island-i Egyetem kutatója.

A csoport 18 jégmintát gyűjtött, két méter mélyre fúrtak a jégtáblákon négy helyszínen, a mintákban műanyagszemcséket, különböző formájú és méretű műszálakat láttak. A kutatók szerint felfedezésük megerősíti azokat a megfigyeléseket, hogy a mikroműanyag-szennyezés koncentrálódik a tengervízhez köthető jégben is.

A szakemberek a mintákat további elemzésnek vetik alá, hogy segítsék a kutatási erőfeszítéseket annak megértésére, miként károsítja a műanyag a halakat, tengeri madarakat és a nagy tengeri emlősöket.
