Poyamba Antarctica inkadziwika kuti “malo aukhondo kwambiri padziko lapansi.Koma tsopano, malo opatulika amenewa akuipitsidwanso.Malinga ndi The Cryosphere, ofufuza apeza ma microplastics kwa nthawi yoyamba mu zitsanzo za chipale chofewa kuchokera ku Antarctica.pepala chikho zimakupiza zopangira

Ofufuza adasonkhanitsa zitsanzo 19 za chipale chofewa kuchokera m'malo osiyanasiyana m'mphepete mwa Ross Ice Shelf, alumali lalikulu kwambiri la ayezi ku Antarctica - zitsanzo zisanu ndi chimodzi kuchokera pafupi ndi malo opangira kafukufuku ndi 13 yotsala "kumalo akutali okhala ndi zopondapo za anthu".Chitsanzo chilichonse chinayesedwa kuti chikhalepo ndi microplastics.

Zomwe zapezazi zikutanthauza kuti kuwonongeka kwa chilengedwe komwe kumachitika chifukwa cha kuwonongeka kwa pulasitiki kungakhale kokulirakulira.Asayansi apeza ma microplastics m'matope a m'nyanja yakuya, m'nyanja ndi pamwamba pamadzi ku Antarctica, koma aka ndi nthawi yoyamba kuti apezeke mu zitsanzo za chipale chofewa.pepala chikho fani yogulitsa

Ofufuza akuganiza kuti pali magwero awiri a microplastics mu chipale chofewa cha Antarctica.Choyamba, mafunde a mpweya amatumiza tinthu ting'onoting'ono ta makilomita masauzande ambiri ku Antarctica.Chachiwiri, anthu asiya chotsatira ku Antarctica, kubweretsa microplastics ndi iwo.

Kodi microplastic ndi chiyani?Kodi zidzakhudza bwanji Antarctica?

Tinthu tating'onoting'ono tosakwana 5 millimeters m'mimba mwake timatchedwa "microplastics".Ndi yaying'ono kuposa njere ya mpunga ndipo sungadziwike ndi maso.Ambiri mwa ma microplastic omwe amapezeka ku Antarctica ndi polyethylene terephthalate (PET), omwe amapezeka m'mabotolo a zakumwa ndi zovala.pepala kapu yaiwisi

Masiku ano, tinthu tating’onoting’ono tating’ono tomwe timapezeka m’mwamba monga Mount Everest komanso mpaka kunyanja yakuya.Tizigawo ting'onoting'ono timeneti timatha kulowa m'thupi kudzera mu chakudya, zakumwa ndi mpweya.Kafukufuku wapeza kukhalapo kwawo m'magazi a anthu ndi mapapo.

Kafukufuku wasonyeza kuti ma microplastics angayambitse "kuwonongeka kwakukulu kwa chilengedwe" ku Antarctica.Kusungunuka kwa cryosphere kumakhala kofulumira pamene ma microplastics amapezeka mu chipale chofewa ndi madzi oundana a mapiri aatali kapena madera a polar.Ma microplastics amatha kukhala madzi oundana mumlengalenga, zomwe zimakhudzanso nyengo.pepala chikho zopangira opanga

Kuphatikiza pa izi, kulowetsedwa kwa ma microplastic ndi zamoyo zam'madzi kumatha kusokonezanso unyolo wonse wa Antarctic biotic.

"Microplastics imatha kukhala ndi zinthu zovulaza zomwe zimayikidwa pamwamba pake, monga zitsulo zolemera ndi ndere.Zinthu izi, zomwe sizikanakhalapo m'malo akutali komanso otetezedwa, zimafika ku Antarctica kudzera pagalimoto ya microplastics. ”zopangira pepala chikho

Choncho, pofuna kuchepetsa kuwonongeka kwa pulasitiki, kuchepetsa kugwiritsa ntchito mankhwala apulasitiki, "mapepala m'malo mwa pulasitiki" ndi ofunika.Pakadali pano, mabizinesi akunyumba ndi akunja akuwunika kugwiritsa ntchito kuyika mapepala m'malo mwa pulasitiki, ndipo apanga udzu wamapepala, zinthu zopangidwa ndi zamkati, mabokosi akumwa, mabokosi ankhomaliro ndi zinthu zina zamapepala kuti zithandizire kuchepetsa padziko lonse lapansi. kugwiritsa ntchito zinthu zapulasitiki.pe paper cup fans
