Antarctica yaimbozivikanwa se“nzvimbo yakachena kwazvo pasi pano. Asi zvino, iyi nzvimbo inoera iri kusvibiswawo. Maererano neThe Cryosphere, vatsvakurudzi vakawana microplastics kekutanga mumasinou echando kubva kuAntarctica.bepa mukombe fan mbishi zvinhu

Vatsvaguri vakaunganidza gumi nemapfumbamwe echando samples kubva kunzvimbo dzakasiyana siyana pamwe neRoss Ice Shelf, yakakura ice sherufu yeAntarctica - masampuli matanhatu kubva padhuze nechiteshi chekutsvagisa uye gumi nematatu asara kubva "kunzvimbo dzirikure dzisina tsoka yemunhu". Sample imwe neimwe yakaedzwa kuvepo kwemicroplastics.

Kuwana kunoreva kuti kukuvadzwa kwezvisikwa kunokonzerwa nekusvibiswa kwepurasitiki kunogona kunge kuri kukurumidza. Masayendisiti akawana microplastics mune yakadzika-gungwa sediment, gungwa uye pamusoro pemvura muAntarctica, asi inguva yekutanga kuwanikwa mumasampuli echando.bepa mukombe fan wholesale

Vatsvakurudzi vanofungidzira kuti kune maviri masosi emicroplastics muchando cheAntarctica. Kutanga, mafungu emhepo anotumira zvimedu zviuru zvemakiromita kure kuAntarctica. Chechipiri, vanhu vakasiya tsoka muAntarctica, vachiunza microplastics navo.

Chii chinonzi microplastic? Ichabata sei Antarctica?

Zvimedu zvepurasitiki zvisingasviki 5 millimeters mudhayamita zvinowanzodanwa se "microplastics". Idiki pane tsanga yemupunga uye haigone kuzivikanwa nemeso. Zvizhinji zve microplastics inowanikwa muAntarctica ndeye polyethylene terephthalate (PET), inowanzowanikwa mumabhodhoro ezvinwiwa uye zvipfeko.mukombe wepepa mbishi

Mazuva ano, ma<em>microplastic anogona kuwanikwa kureba seMount Everest uye kusvika pakadzika dzika segungwa. Zvidiki izvi zvinogona kupinda mumuviri kuburikidza nekudya, zvinwiwa uye mweya. Zvidzidzo zvakaona kuvepo kwavo muropa revanhu nemapapu.

Zvidzidzo zvakaratidza kuti microplastics inogona kukonzera "kukuvadza kwakanyanya kwezvakatipoteredza" kuAntarctica. Kunyunguduka kweiyo cryosphere kunokwanisa kukurumidza kana microplastics inowanikwa muchando uye chando chemakomo marefu kana nzvimbo dzepolar. Microplastics inogona kuita ice nuclei mumhepo, zvichiwedzera kukanganisa mamiriro ekunze.bepa kapu mbishi zvinhu mugadziri

Pamusoro peizvi, kuiswa kwe microplastics nezvisikwa zvemugungwa kunogonawo kukanganisa zvachose Antarctic biotic chain.

“Microplastics inogona kunge iine zvinhu zvinokuvadza zvakanamirwa paari, senge heavy metal nealgae. Zvinhu izvi, zvingadai zvisipo munzvimbo idzi dziri kure uye dzakachengetedzwa, zvinosvika kuAntarctica kuburikidza nemotokari yemicroplastics. "kapu yepepa raw material

Nokudaro, kuitira kuderedza kukuvadza kwepurasitiki, kuderedza kushandiswa kwezvigadzirwa zvepurasitiki, "pepa panzvimbo yepurasitiki" inokosha. Parizvino, ese epamba neekunze mabhizinesi emapepa uye ekurongedza ari kuongorora kushandiswa kwepepa kurongedza pachinzvimbo chepurasitiki kurongedza, uye akagadzira mashanga emapepa, pulp akaumbwa zvigadzirwa, zvinwiwa mabhokisi, lunch mabhokisi uye zvimwe zvigadzirwa zvemapepa kuti zvibatsire mukuderedza pasi rose. yekushandiswa kwemidziyo yepurasitiki.pe bepa mukombe mafeni
