Eminyakeni yamuva nje, ukukhathazeka ngokusakazeka kwe-microplastics kuye kwanda. Kusolwandle, ngisho nasezilwaneni nasezitshalweni, nasemanzini asemabhodleleni esiwaphuza nsuku zonke.
Ama-Microplastics abonakala ekhona yonke indawo. Futhi okungathandeki nakakhulu ukuthi akukhona nje kuphela yonke indawo esizungezile, kodwa futhi ngokungalindelekile emzimbeni womuntu.
Ngokwabacwaningi baseNyuvesi yaseNew Mexico, ama-microplastic aphuma emanzini nokudla esikudlayo, kanye nomoya esiwuphefumulayo, asuka emathunjini ethu aye kwezinye izingxenye zomzimba, njengezinso, isibindi ngisho nobuchopho. .
Ukuze bafinyelele lesi siphetho esisha, amasonto amane ososayensi banikeza amagundane amanzi anenani lama-microplastic okucatshangwa ukuthi abantu bayawadla isonto ngalinye. Ucwaningo lwangaphambilini lubonise ukuthi amagremu amahlanu e-microplastic angena emzimbeni womuntu isonto ngalinye, cishe isisindo sekhadi lesikweletu.
Ngokuka-Eliseo Castillo, uprofesa ohlangene we-gastroenterology kanye ne-hepatology e-University of New Mexico School of Medicine, ukutholakala kokuthi ama-microplastics aphuma emathunjini aye kwezinye izicubu emzimbeni womuntu kumayelana. Ngokusho kwakhe, ishintsha amangqamuzana omzimba, abizwa ngokuthi ama-macrophages, futhi lokhu kungaholela ekuvuvukeni emzimbeni.
Ngaphezu kwalokho, kolunye ucwaningo, uDkt. Castillo uzogxila endleleni ukudla komuntu okuthinta ngayo indlela ama-microplastic amuncwa ngayo umzimba.
Yena nethimba lakhe bazofaka izilwane zelabhu ekudleni okuhlukahlukene okuhlukahlukene, okuhlanganisa okunamafutha amaningi kanye ne-fiber ephezulu. Izingcezu ze-microplastic zizoba yingxenye "yemenyu" yezinye zezilwane, kanti ezinye ngeke.
Ngokocwaningo olwanyatheliswa kumagazini i-Environmental Pollution, nokho, kungakhathaliseki ukuthi hlobo luni lokudla esikudlayo, awekho ama-microplastics angabalekayo. Ososayensi bathole ukuthi amaprotheni angama-90%, okubandakanya ezinye izindlela ze-vegan, aqukethe ama-microplastics, axhumene nokubi. zezempilo imiphumela.
Ingabe amapulasitiki angaboli angasiza?
Ukuhlehla okubhekiswe kumapulasitiki asetshenziswa kanye kuphela kubone izinkampani eziningi zifuna ukusebenzisa ezinye izindlela ezithi zingabola kakhulu noma zivundiswe. Kodwa kwezinye izimo lezi zindlela zingase zihlanganise inkinga ye-microplastic. Ucwaningo olwenziwa ososayensi baseNyuvesi yasePlymouth e-UK bathola ukuthi izikhwama ezibhalwe ngokuthi “ezibolayo” zingathatha iminyaka ukuthi zihlakazeke, futhi nalapho ngokuvamile zihlukana zibe izingcezu ezincane kunezingxenye zazo zamakhemikhali. (Funda kabanzi mayelana nokuthi kungani ama-biodegradables engeke axazulule inkinga yepulasitiki kulesi sihloko sika-Kelly Oakes.)
Kuthiwani ngokushintshela emabhodleleni engilazi?
Ukushintsha amaphakheji epulasitiki kungasiza ekwehliseni ukuchayeka - amanzi ompompi anamazinga aphansi we-microplastics kunamanzi kusukela emabhodleleni epulasitiki. Kodwa futhi kuzoba nemiphumela yemvelo. Ngenkathi amabhodlela engilazi anezinga eliphezulu lokugaywa kabusha, nabo banayo indawo ephakeme yemvelo kunepulasitiki nezinye izinto ezisetshenziselwa uketshezi njengamakhathoni eziphuzo namathini e-aluminium. Lokhu kungenxa yokuthi ukumbiwa kwe-silica, ingilazi eyenziwe ngayo, kungabangela umonakalo omkhulu emvelweni, okuhlanganisa ukuwohloka komhlaba kanye nokulahleka kwezinhlobonhlobo zezinto eziphilayo. Ngisho nalezi zinto ezingezona ezepulasitiki, kunzima ukubalekela ama-microplastics ngokuphelele. Izifundo eziholwa nguSherri Mason ePennsylvania State University zithole ukuthi azikho nje kuphela amanzi ompompi, lapho ukungcola okuningi kwepulasitiki kuvela emicu yezingubo, kodwa futhi usawoti olwandle ngisho nobhiya. Funda kabanzi mayelana nokuthi ingilazi noma ipulasitiki ingcono emvelweni.
Ingabe kukhona okungenziwa ukuze kuncishiswe ama-microplastic?
Ngenhlanhla, kukhona ithemba. Abacwaningi benza izindlela eziningi zokusiza ukuqeda ukungcoliswa kwepulasitiki endaweni yethu. Enye indlela kuye kwaba ukuphendukela kusikhunta namagciwane adla ipulasitiki, ayihlephule ngesikhathi. Izinhlobo zezibungu zebhungane ezingashwabadela i-polystyrene nazo zinikeze esinye isisombululo esingaba khona. Abanye babheke ukusebenzisa amasu okuhlunga amanzi noma ukwelashwa kwamakhemikhali okungasusa ama-microplastics.
