Nrog tsawg tus neeg, ib tus yuav xav tias Arctic yuav dhau los ua thaj chaw tsis muaj yas, tab sis txoj kev tshawb fawb tshiab qhia tau tias tsis deb ntawm qhov tseeb.Cov kws tshawb fawb kawm txog dej hiav txwv Arctic tab tom nrhiav cov khib nyiab yas nyob txhua qhov chaw.Raws li Tatiana Schlossberg ntawm New York Times, cov dej hauv Arctic zoo li cov av pov tseg rau cov yas ntab nrog dej hiav txwv.
Yas tau pom nyob rau xyoo 2013 los ntawm pab pawg neeg tshawb fawb thoob ntiaj teb thaum lub sijhawm tsib lub hlis mus ncig thoob ntiaj teb hauv nkoj tshawb fawb Tara.Raws li txoj kev, lawv coj cov qauv dej hiav txwv los saib xyuas cov pa phem.Txawm hais tias cov ntsiab lus ntawm cov yas feem ntau tsis tshua muaj, lawv tau nyob hauv ib cheeb tsam tshwj xeeb hauv Greenland thiab nyob rau sab qaum teb ntawm Barents Hiav Txwv qhov twg cov concentrations txawv txawv.Lawv tau luam tawm lawv qhov kev tshawb pom hauv phau ntawv Journal Science Advances.
Cov yas zoo li tau txav mus rau hauv qab ntawm lub thermohaline gyre, ib qho dej hiav txwv "conveyor Belt" tam sim no uas nqa dej los ntawm Dej Hiav Txwv Atlantic qis mus rau cov ncej."Greenland thiab Barents Hiav Txwv yog qhov kawg ntawm cov kav dej polar no," tus thawj coj tshawb fawb Andrés Cozar Cabañas, tus kws tshawb fawb ntawm University of Cadiz hauv Spain, tau hais hauv xov xwm tshaj tawm.
Cov kws tshawb fawb kwv yees tias tag nrho cov yas hauv cheeb tsam yog ntau pua tons, suav nrog ntau pua txhiab tus me me ib square kilometers.Cov nplai tuaj yeem loj dua, cov kws tshawb fawb tau hais tias, vim tias cov yas tuaj yeem khaws cia rau ntawm ntug dej hiav txwv hauv cheeb tsam.
Eric van Sebille, tus kws sau ntawv ntawm txoj kev tshawb no, hais rau Rachel van Sebille hauv The Verge: "Txawm hais tias feem ntau ntawm Arctic zoo, muaj Bullseye, muaj qhov kub thiab txias nrog dej qias neeg heev."
Txawm hais tias nws tsis zoo li tias cov yas yuav raug pov tseg ncaj qha rau hauv hiav txwv Barents (lub cev dej khov txias ntawm Scandinavia thiab Russia), qhov xwm txheej ntawm cov yas pom tau pom tias nws tau nyob hauv dej hiav txwv rau qee lub sijhawm.
"Fragments ntawm cov yas uas tej zaum yuav pib yog ntiv tes los yog ko taw loj dhau los ua nkig thaum raug tshav ntuj, thiab tom qab ntawd tawg mus rau hauv cov khoom me me thiab me me, nws thiaj li tsim cov yas me me, uas peb hu ua microplastic."- Carlos Duarte, hais tias kev tshawb fawb co-sau Chris Mooney ntawm Washington Post.“Cov txheej txheem no yuav siv sij hawm ntau xyoo mus rau kaum xyoo.Yog li cov ntaub ntawv uas peb tab tom pom qhia tias nws nkag mus rau hauv dej hiav txwv ntau xyoo dhau los. "
Raws li Schlossberg, 8 lab tons ntawm cov yas nkag mus rau hauv dej hiav txwv txhua xyoo, thiab niaj hnub no muaj txog 110 lab tons ntawm cov yas ntim hauv ntiaj teb cov dej.Thaum cov pov tseg yas hauv Arctic dej tsawg dua li ib feem pua ​​​​ntawm tag nrho, Duarte hais rau Muni tias cov khoom pov tseg yas hauv Arctic tsuas yog pib xwb.Ntau xyoo ntawm cov yas los ntawm sab hnub tuaj Asmeskas thiab Europe tseem nyob ntawm txoj kev thiab nws yuav xaus rau hauv Arctic.
Cov kws tshawb fawb tau txheeb xyuas ntau qhov chaw sov sov hauv lub ntiaj teb cov dej hiav txwv uas microplastics zoo li khaws cia.Tam sim no qhov kev txhawj xeeb yog tias Arctic yuav koom nrog cov npe no."Lub cheeb tsam no yog qhov kawg tuag, dej hiav txwv ntws tawm cov khib nyiab ntawm qhov chaw," tus kws sau ntawv Maria-Luise Pedrotti tau hais hauv tsab ntawv tshaj tawm."Peb tuaj yeem pom qhov tsim ntawm lwm qhov pov tseg hauv ntiaj teb yam tsis muaj kev nkag siab zoo txog qhov txaus ntshai rau cov tsiaj hauv zos thiab tsiaj txhu."
Txawm hais tias qee lub tswv yim pie-hauv-lub-ntev los ntxuav dej hiav txwv cov khib nyiab los ntawm cov yas tam sim no tab tom tshawb nrhiav, tshwj xeeb tshaj yog Ocean Cleanup project, cov kws tshawb fawb tau xaus rau hauv xov xwm tshaj tawm tias qhov kev daws teeb meem zoo tshaj plaws yog ua haujlwm hnyav dua los tiv thaiv cov yas zoo li. ua ntej.Hauv dej hiav txwv.
