Nevanhu vashoma, munhu angafunga kuti Arctic ingave nzvimbo isina plastiki, asi chidzidzo chitsva chinoratidza kuti haisi kure zvakanyanya kubva kuchokwadi.Vatsvagiri vari kudzidza kuArctic Ocean vari kuwana marara epurasitiki kwese kwese.Maererano naTatiana Schlossberg weThe New York Times, mvura dzeArctic dzinoita senzvimbo yokurasira mapurasitiki anoyangarara nemafungu emugungwa.
Plastiki yakawanikwa muna 2013 nechikwata chepasi rose chevaongorori parwendo rwemwedzi mishanu kutenderera pasirese vari muchikepe chetsvakiridzo cheTara.Vari munzira, vakatora samples dzemvura yegungwa kuti vatarise kusvibiswa kwepurasitiki.Kunyangwe kuwanda kwemapurasitiki kwaiwanzo kuderera, aive mune imwe nzvimbo muGreenland uye kuchamhembe kweGungwa reBarents uko kukwirisa kwaive kwakakwira zvisingaite.Vakaburitsa zvavakawana mumagazini inonzi Science Advances.
Plastiki inoratidzika kunge iri kufamba ichienda padivi pe thermohaline gyre, yegungwa "conveyor belt" ikozvino inotakura mvura kubva kuzasi kweAtlantic Ocean kuenda kumatanda."Greenland neGungwa reBarents zvakafa mupombi iyi," munyori anotungamira wekudzidza Andrés Cozar Cabañas, muongorori paYunivhesiti yeCadiz kuSpain, akadaro mukuburitswa kwenhau.
Vatsvakurudzi vanofungidzira kuti huwandu hwepurasitiki huri munharaunda yacho mazana ematani, hunosanganisira mazana ezviuru zvezvidimbu zviduku pakiromita imwe.Chiyero chacho chinogona kunge chakatokura, vatsvakurudzi vakati, sezvo plastiki inogona kunge yakaunganidza pasi pegungwa munzvimbo.
Eric van Sebille, munyori pamwe chete weongororo iyi, akaudza Rachel van Sebille muThe Verge kuti: “Kunyange zvazvo nzvimbo zhinji dzeArctic dzakanaka, kune Bullseye, kune iyi hotspot ine mvura yakasvibiswa zvakanyanya.
Kunyange zvazvo zvisingabviri kuti plastiki ichakandwa zvakananga muGungwa reBarents (mvura inotonhora yeaizi pakati peScandinavia neRussia), mamiriro epurasitiki akawanikwa anoratidza kuti yave iri mugungwa kwenguva yakati.
"Zvimedu zvepurasitiki zvinogona kutanga kuita inches kana tsoka muhukuru zvinova zvisina kusimba kana zvavhenekwa nezuva, zvobva zvaputsika kuita tudikidiki tudiki, zvozopedzisira zvaita chidimbu chepurasitiki chakakura mamirimita, chatinodaidza kuti microplastic."- Carlos Duarte, akadaro munyori-munyori Chris Mooney weThe Washington Post.“Izvi zvinotora makore akawanda kusvika makumi emakore.Saka mhando yezvinhu zvatiri kuona zvinoratidza kuti zvakapinda munyanza makumi emakore apfuura. ”
Sekureva kwaSchlossberg, 8 miriyoni matani epurasitiki anopinda mumakungwa gore rega rega, uye nhasi anenge 110 miriyoni matani epurasitiki anoungana mumvura yenyika.Nepo marara epurasitiki mumvura yeArctic ari pasi pechikamu chimwe chete kubva muzana, Duarte akaudza Muni kuti kuunganidzwa kwemarara epurasitiki muArctic kuchangotanga.Makumi emakore epurasitiki kubva kumabvazuva kweUS neEurope achiri munzira uye anozopedzisira ave muArctic.
Vatsvagiri vakaona akati wandei subtropical gyres mumakungwa epasirese uko microplastics inowanzo kuunganidza.Chave kunetsa ndechekuti Arctic ichajoina iyi runyorwa."Nzvimbo iyi imagumo, mafungu egungwa anosiya marara pamusoro," munyori-munyori wekudzidza Maria-Luise Pedrotti akadaro mukuburitswa kwenhau."Tinogona kunge tichiona kuumbwa kweimwezve nzvimbo yekurasira pasi pasi tisinganzwisise zvizere njodzi kumaruva nemhuka dzemuno."
Kunyangwe mamwe mapie-in-the-sky mazano ekuchenesa marara egungwa kubva mupurasitiki ari kuongororwa, kunyanya chirongwa cheOcean Cleanup, vaongorori vakapedzisa mukuburitswa kwenhau kuti mhinduro yakanakisa ndeyekushanda nesimba kudzivirira kutaridzika kwepurasitiki. chekutanga.Munyanza.
