Kwiminyaka yakutshanje, ukuxhalaba malunga nokusasazeka kwe-microplastics kuye kwanda. Kuselwandle, nakwizilwanyana nakwizityalo, nakumanzi asebhotileni esiwasela yonke imihla.
IMicroplastics ibonakala ikhona kuyo yonke indawo. Kwaye into engathandekiyo ngakumbi kukuba akukhona nje kuyo yonke indawo ejikeleze thina, kodwa ngokungalindelekanga kumzimba womntu.
Ngokutsho kwabaphandi kwiYunivesithi yaseNew Mexico, i-microplastics emanzini kunye nokutya esikutyayo, kunye nomoya esiwuphefumlayo, zenza indlela yazo ukusuka emathunjini ethu ukuya kwamanye amalungu omzimba, njengezintso, isibindi kunye nengqondo. .
Ukufikelela kwesi sigqibo sitsha, iiveki ezine izazinzulu zanika amanzi eempuku kunye nesixa se-microplastics ekucingelwa ukuba abantu baya kuginya iveki nganye. Uphononongo lwangaphambili lubonise ukuba iigram ezintlanu ze-microplastic zingena emzimbeni womntu veki nganye, obunzima bekhadi letyala.
Ngokuka-Eliseo Castillo, unjingalwazi onxulumene ne-gastroenterology kunye ne-hepatology kwiYunivesithi yaseNew Mexico School of Medicine, ukufumanisa ukuba ii-microplastics zenza indlela yazo ukusuka emathunjini ziye kwezinye izicubu emzimbeni womntu. Ngokutsho kwakhe, iguqula iiseli zomzimba, ezibizwa ngokuba yi-macrophages, kwaye oku kunokukhokelela ekudumbeni emzimbeni.
Ukongezelela, kolunye uhlolisiso, uGqr. Castillo uya kugxininisa kwindlela ukutya komntu okuchaphazela ngayo indlela i-microplastics efunxwa ngayo ngumzimba.
Yena kunye neqela lakhe baya kubeka izilwanyana zelebhu kwizidlo ezininzi ezahlukeneyo, kubandakanya enye ephezulu ngamafutha kunye nenye ephezulu kwifayibha. Iziqwenga ze-microplastic ziya kuba yinxalenye "yemenyu" yezinye izilwanyana, ngelixa ezinye aziyi.
Ngokophononongo olupapashwe kwijenali ye-Environmental Pollution, nangona kunjalo, kungakhathaliseki ukuba luhlobo luni lokutya esikutyayo, akukho microplastics ebalekayo. Iingcali zenzululwazi ziye zafumanisa ukuba iipesenti ezingama-90 zeeprotheyini, kubandakanywa ezinye iindlela ze-vegan, ziqulethe i-microplastics, edityaniswe ne-negative. impilo ziphumo.
Ngaba iiplastiki ezingonakaliswa ngebhayoloji zinganceda?
Ukubuyela umva ngokuchasene nokusetyenziswa kweplastiki enye kubone iinkampani ezininzi zifuna ukusebenzisa ezinye iindlela ezithi zinokonakala ngakumbi okanye zivundiswe. Kodwa kwezinye iimeko ezi ndlela zinokuthi zidibanise ingxaki ye-microplastic. Uphando olwenziwa ngoososayensi kwiYunivesithi yasePlymouth e-UK bafumanisa ukuba iingxowa ezibhalwe “njenge-biodegradable” zinokuthatha iminyaka ukuba ziqhekeke, kwaye nalapho ubukhulu becala ziqhekeka zibe ngamaqhekeza amancinci kuneenxalenye zazo zekhemikhali. (Funda ngakumbi malunga nokuba kutheni i-biodegradables ingasombululi ingxaki yeplastiki kweli nqaku nguKelly Oakes.)
Kuthekani ngokutshintshela kwiibhotile zeglasi?
Ukutshintsha ukupakishwa kweplastiki kunokunceda ukunciphisa ukuvezwa- amanzi ompompo anamanqanaba asezantsi e-microplastics ngaphezu kwamanzi kwiibhotile zeplastiki. Kodwa iya kuba neempembelelo zokusingqongileyo. Ngelixa iibhotile zeglasi zinezinga eliphezulu lokurisayikilisha, nabo banayo umgangatho ophezulu wokusingqongileyo kuneplastiki kunye nezinye iipakethe ezisetyenziselwa ulwelo ezifana neebhokisi zeziselo kunye neetoti ze-aluminiyam. Oku kungenxa yokuba imigodi ye-silica, eyenziwe ngeglasi, inokubangela umonakalo omkhulu wokusingqongileyo, kubandakanywa ukuwohloka komhlaba kunye nelahleko yezinto ezahlukahlukeneyo. Nokuba ngezi zixhobo zingezo zeplastiki, kunzima ukubaleka ii-microplastics ngokupheleleyo. Izifundo ezikhokelwa nguSherri Mason kwiYunivesithi yasePennsylvania State zifumanise ukuba azikho kuphela amanzi etephu, apho ungcoliseko oluninzi lweplastiki luvela kwiifayibha zempahla, kodwa kwakhona ityuwa yolwandle kunye nebhiya. Funda ngakumbi malunga nokuba iglasi okanye iplastiki ingcono kokusingqongileyo.
Ngaba ikho into enokwenziwa ukunciphisa iiplastiki ezincinci?
Ngethamsanqa, kukho ithemba. Abaphandi baphuhlisa inani leendlela zokunceda ukulahla ungcoliseko lweplastiki kwindawo yethu. Enye indlela iye yaba kukuguqula umngundo kunye neebhaktheriya ezondla iplastiki, ukuyiqhekeza kwinkqubo. Iintlobo zemibungu yebhungane enokuthi iqwenge i-polystyrene ikwanike esinye isisombululo esinokubakho. Abanye bajonge ukusebenzisa iindlela zokucoca amanzi okanye unyango lweekhemikhali ezinokususa i-microplastics.
