Kafukufuku watsopano wochitidwa ndi gulu la ofufuza ochokera ku Germany, Great Britain ndi Canada apeza kuti algae omwe amamera pansi pa madzi oundana a m'nyanja ya Arctic "ali oipitsidwa kwambiri" ndi microplastics, zomwe zimawopseza anthu omwe ali m'gulu la chakudya, inatero UPI.
Algae wandiweyani wotchedwa Melosira arctica munali pafupifupi 31,000 microplastic particles pa kiyubiki mita, pafupifupi 10 nthawi ndende m'madzi ozungulira, ofufuza anapeza, otchulidwa BTA. Malinga ndi iwo, avareji anali pafupifupi 19,000, kutanthauza kuti ma clumps ena mwina anali ndi tinthu tating'ono tating'ono ta 50,000 pa kiyubiki mita.
Kafukufukuyu anachitidwa ku Helmholtz Center for Polar and Marine Research ku Alfred Wegener Institute, pogwiritsa ntchito zitsanzo zomwe zinasonkhanitsidwa paulendo ndi chombo chofufuzira cha Polarstern mu 2021. Zotsatira za ntchito ya gulu la mayiko zinasindikizidwa Lachisanu mu magazini "Environmental Science and Technology".
Deoni Allen wa ku yunivesite ya Canterbury anati: "Algae wa filament ndi wonyezimira, womata, choncho amatha kutenga ma microplastics kuchokera mumlengalenga panyanja, m'madzi a m'nyanja, kuchokera ku ayezi wozungulira komanso malo ena aliwonse omwe amadutsa." kutulutsidwa kwa media. ndi yunivesite ya Birmingham, yomwe ili m'gulu la kafukufuku.
Nsomba, monga cod, zimadya algae ndipo zimadyedwa ndi nyama zina, kuphatikizapo anthu, potero zimatumiza "mapulasitiki osiyanasiyana" kuphatikizapo polyethylene, polyester, polypropylene, nayiloni ndi acrylic, zomwe zimapezeka m'matupi aumunthu.
“Anthu a ku Arctic makamaka amadalira chakudya cha m’madzi kuti apeze zomanga thupi, mwachitsanzo posaka nyama kapena kusodza,” anatero katswiri wa zamoyo Melanie Bergman, yemwe anatsogolera kafukufukuyu. Izi zikutanthauza kuti amakumananso ndi zotsatira za microplastics ndi mankhwala ake. "Microplastics yapezeka kale m'matumbo a munthu, magazi, mitsempha, mapapo, placenta ndi mkaka wa m'mawere ndipo zingayambitse kutupa, koma zotsatira zake zonse zakhala zikudziwikabe," akufotokoza Bergman.
Zingwe za algae zakufa zimanyamulanso ma microplastics mwachangu kwambiri kupita kunyanja yakuya, zomwe zimafotokozera kuchuluka kwa ma microplastics mumatope - chinthu china chofunikira kwambiri pa kafukufuku watsopano. ndere zimakula mofulumira pansi pa madzi oundana a m’nyanja m’miyezi yachilimwe ndi yachilimwe, ndipo kumeneko zimapanga unyolo wa maselo a utali wa mita womwe umasanduka minyewa maselo akamwalira. Pakatha tsiku limodzi, amatha kumira mamita zikwizikwi mpaka pansi pamadzi akuya a nyanja. Bergman anati: "Pomaliza tidapeza chifukwa chomwe timayezera kuchuluka kwa ma microplastics m'matope a m'nyanja yakuya," akutero Bergman. Ananenanso kuti kafukufuku akuwonetsa kuti kuchepetsa kupanga pulasitiki ndi njira yabwino kwambiri yochepetsera kuipitsa kwamtunduwu.
"Ndicho chifukwa chake izi ziyenera kukhala patsogolo pa mgwirizano wapadziko lonse wapulasitiki womwe ukukambidwa," adatero Bergman. Adzakhala nawo gawo lotsatira la zokambirana kuti apange mgwirizano wa UN kuti achepetse kuwonongeka kwa pulasitiki. Zokambirana zikuyembekezeka kuyamba ku Paris kumapeto kwa Meyi.
