Uphononongo olutsha lweqela labaphandi abavela eJamani, iGreat Britain kunye neKhanada lifumene ukuba i-algae ekhula phantsi kweqhwa elwandle e-Arctic "ingcoliseke kakhulu" nge-microplastics, ibeka ingozi kubantu kwikhonkco lokutya, kubika i-UPI.
I-algae exineneyo eyaziwa ngokuba yi-Melosira arctica iqulethe i-avareji ye-31,000 ye-microplastic particles per cubic meter, malunga namaxesha e-10 yoxinaniso emanzini ambi, abaphandi bafumene, abakhankanywe yi-BTA. Ngokutsho kwabo, i-avareji yayijikeleze i-19,000, okuthetha ukuba ezinye ii-clumps zinokuba zininzi njenge-50,000 microplastic particles per cubic meter.
Uphando lwenziwa kwi-Helmholtz Centre yoPhando lwePolar kunye noLwandle kwi-Alfred Wegener Institute, ngokusekelwe kwiisampuli eziqokelelwe ngexesha lokuhamba kunye nomkhumbi wophando we-Polarstern kwi-2021. Iziphumo zomsebenzi weqela lamazwe ngamazwe zapapashwa ngoLwesihlanu kwi- ijenali ”Nzululwazi ngokusiNgqongileyo kunye neTekhnoloji”.
"I-algae ene-filament ine-slimy, texture encangathi, ngoko ke inokuchola i-microplastics kwi-atmospheric deposition elwandle, kumanzi olwandle ngokwawo, ukusuka kumkhenkce ojikelezileyo kunye nakuwuphi na umthombo odlulayo," utshilo uDeoni Allen weYunivesithi yaseCanterbury. ukukhutshwa kweendaba. kunye neYunivesithi yaseBirmingham, eyinxalenye yeqela lophando.
Iintlanzi, ezifana ne-cod, zitya kwi-algae kwaye zidliwa zezinye izilwanyana, kuquka nabantu, ngaloo ndlela zihambisa "iiplastiki ezahlukeneyo" ezibandakanya i-polyethylene, i-polyester, i-polypropylene, i-nylon kunye ne-acrylic, ezifumaneka kwimizimba yabantu.
Isazi ngebhayoloji uMelanie Bergman, owayekhokele kolu phando sithi: “Abantu baseArctic baxhomekeke ngakumbi kuthungelwano lokutya kwaselwandle ukuze bafumane iiproteni, ngokomzekelo ngokuzingela okanye ngokuloba. “Oku kuthetha ukuba bakwachanabeke kwiziphumo zemicroplastics kunye neekhemikhali zakhe. "I-Microplastics sele ifunyenwe emathunjini omntu, igazi, imithambo, imiphunga, i-placenta kunye nobisi lwebele kwaye inokubangela ukusabela kokuvuvukala, kodwa iziphumo ezipheleleyo ukuza kuthi ga ngoku azikhange zihlolwe," kuchaza uBergman.
Izigaqa ze-algae efileyo zikwahambisa ii-microplastics ngakumbi ngokukhawuleza kulwandle olunzulu, oluchaza ukugxila okuphezulu kwe-microplastics kwintlenga - enye into ephambili yokufunyaniswa kophando olutsha. Ubulembu bukhula ngokukhawuleza phantsi komkhenkce wolwandle ebudeni beenyanga zasentlakohlaza nezasehlotyeni, yaye apho benza imixokelelwane yeeseli ezibude buziimitha ezijika zibe ziziqhuma xa iiseli zisifa. Ngosuku nje, banokutshona amawaka eemitha ukuya ezantsi kumanzi anzulu olwandle. "Ekugqibeleni sifumene ingcaciso ebambekayo yokuba kutheni sihlala silinganisa ezona zixa ziphezulu ze-microplastics kwindawo enzulu yolwandle," utshilo uBergman. Wongeze ukuba uphando lubonisa ukuba ukunciphisa imveliso yeplastiki yeyona ndlela isebenzayo yokunciphisa olu hlobo longcoliseko.
“Kungoko oku kufanele ukuba kube yeyona nto iphambili kwisivumelwano seplastiki sehlabathi ekuxoxwa ngaso,” utshilo uBergman. Uya kuzimasa umjikelo olandelayo weentetho zokuphuhlisa isivumelwano se-UN ukunciphisa ungcoliseko lweplastiki. Iintetho zimiselwe ukuqala eParis ekupheleni kukaMeyi.
