I-Antarctica yake yaziwa ngokuthi “indawo ehlanzekile kunazo zonke emhlabeni.Kodwa manje, lendawo engcwele nayo iyangcoliswa.Ngokusho kweThe Cryosphere, abacwaningi bathole ama-microplastics okokuqala ngqa kumasampula eqhwa avela e-Antarctica.iphepha indebe fan impahla eluhlaza

Abacwaningi baqoqe amasampula eqhwa angu-19 ezindaweni ezihlukahlukene eduze kwe-Ross Ice Shelf, ishalofu leqhwa elikhulu kunawo wonke e-Antarctica - amasampula ayisithupha eduze kwesiteshi socwaningo kanye nangu-13 asele “ezindaweni ezikude ezinomlando omncane womuntu”.Isampula ngayinye ihlolwe ukuba khona kwama-microplastics.

Okutholakele kusho ukuthi umonakalo wemvelo obangelwa ukungcoliswa kwepulasitiki ungase ukhule ngesivinini.Ososayensi bathole ama-microplastics emanzini ajulile olwandle, olwandle namanzi angaphezulu e-Antarctica, kodwa kungokokuqala ngqa ukuthi atholakale kumasampula eqhwa.iphepha indebe fan wholesale

Abacwaningi bacabanga ukuthi kunemithombo emibili ye-microplastic eqhweni lase-Antarctica.Okokuqala, imisinga yomoya ithumela izinhlayiya eziqhele ngezinkulungwane zamakhilomitha e-Antarctica.Okwesibili, abantu bashiye umkhondo e-Antarctica, beza nama-microplastic.

Iyini i-microplastic?Izoyithinta kanjani i-Antarctica?

Izinhlayiya zepulasitiki ezingaphansi kwamamilimitha angu-5 ububanzi zibizwa ngokuthi "ama-microplastics".Incane kunohlamvu lwerayisi futhi ayikwazi ukubonakala ngeso lenyama.Iningi lama-microplastics atholakala e-Antarctica yi-polyethylene terephthalate (PET), evame ukutholakala emabhodleleni eziphuzo nasezimpahleni.inkomishi yephepha eluhlaza

Namuhla, ama-microplastic angatholakala phezulu eNtabeni i-Everest futhi aze afike phansi ekujuleni kolwandle.Lezi zinhlayiya ezincane zingangena emzimbeni ngokudla, isiphuzo nomoya.Ucwaningo luthole ukuba khona kwazo egazini nasemaphashini omuntu.

Ucwaningo luye lwabonisa ukuthi i-microplastics ingabangela "umonakalo omkhulu kakhulu wemvelo" e-Antarctica.Ukuncibilika kwe-cryosphere cishe kuzosheshiswa lapho ama-microplastics etholakala eqhweni naseqhweni lezintaba eziphakeme noma izindawo ezipholile.Ama-Microplastics angaba ama-ice nuclei emkhathini, aphazamise kakhulu isimo sezulu.umkhiqizi wenkomishi yephepha

Ngaphezu kwalokhu, ukungeniswa kwama-microplastics yizinto eziphilayo zasolwandle nakho kungathinta kabi lonke iketango le-Antarctic biotic.

“Ama-Microplastic angase abe nezinto eziyingozi ezinamathele endaweni yawo, njengezinsimbi ezisindayo nolwelwe.Lezi zinto, ebezingeke zibe khona kulezi zindawo ezikude kakhulu nezivikelekile, zifika e-Antarctica ngemoto yama-microplastics.”inkomishi yephepha lempahla eluhlaza

Ngakho-ke, ukuze kuncishiswe ukulimala kwepulasitiki, ukunciphisa ukusetshenziswa kwemikhiqizo yepulasitiki, "iphepha esikhundleni sepulasitiki" liyadingeka.Njengamanje, amabhizinisi asekhaya nakwamanye amazwe kanye namabhizinisi okupakisha ahlola ukusetshenziswa kwephepha lokupakisha esikhundleni sokupakisha epulasitiki, futhi athuthukise utshani bephepha, imikhiqizo ebunjiwe ye-pulp, amabhokisi eziphuzo, amabhokisi esidlo sasemini neminye imikhiqizo esekwe emaphepheni ukuze kube neqhaza ekunciphiseni umhlaba. ukusetshenziswa kwezinto zepulasitiki.pe paper cup abalandeli
