Mumakore achangopfuura, kunetseka pamusoro pekupararira kwe microplastics kwave kuchikura. Iri mumakungwa, kunyange mumhuka nemiti, uye mumvura yakabhoderedzwa tinonwa zuva nezuva.
Microplastics inoita kunge iri kwese kwese. Uye izvo zvinonyanya kufadza ndezvekuti hazvisi chete kwese kwakatikomberedza, asiwo zvisingatarisirwi mumuviri wemunhu.
Maererano nevatsvakurudzi veYunivhesiti yeNew Mexico, microplastics kubva mumvura uye zvokudya zvatinodya, pamwe nemhepo yatinofema, inoita nzira yavo kubva mumatumbo edu kune dzimwe nhengo dzomuviri, dzakadai seitsvo, chiropa uye kunyange uropi. .
Kuti vasvike pamhedziso itsva iyi, kwemavhiki mana masayendisiti akapa mbeva mvura ine huwandu hwemicroplastics inofungidzirwa kuti vanhu vanodya svondo rega rega. Zvidzidzo zvakapfuura zvakaratidza kuti magiramu mashanu emicroplastic anopinda mumuviri wemunhu svondo rega rega, zvinova huremu hwekadhi rechikwereti.
Sekureva kwaEliseo Castillo, purofesa we gastroenterology uye hepatology paYunivhesiti yeNew Mexico Chikoro cheMishonga, kuwanikwa kwekuti microplastics iri kuita nzira yavo kubva muura kuenda kune mamwe matissue mumuviri wemunhu kune chekuita. Maererano naye, inoshandura masero ekudzivirira zvirwere, anonzi macrophages, uye izvi zvinogona kutungamirira mukuzvimba mumuviri.
Uyezve, mune imwe tsvakurudzo, Dr. Castillo achatarisa kuti kudya kwemunhu kunokanganisa sei nzira iyo microplastics inotorwa nemuviri.
Iye nechikwata chake vanozoisa mhuka dzemurabhoritari kudya kwakasiyana siyana, kusanganisira imwe yakakwira mumafuta uye imwe yakakwira mufiber. Zvidimbu zve microplastic zvichava chikamu che "menyu" yeimwe mhuka, asi vamwe havazoiti.
Maererano nekuongorora kwakabudiswa mumagazini inonzi Environmental Pollution, zvisinei, pasinei nemhando yezvokudya zvatinodya, hapana kutiza microplastics. Masayendisiti akawana kuti 90% yemapuroteni, kusanganisira vegan dzimwe nzira, ane microplastics, iyo yakabatanidzwa kune yakaipa. utano migumisiro.
Mapurasitiki anoodegradable angabatsira here?
The backlash against single-use plastics kwakaona makambani mazhinji achitsvaga kushandisa dzimwe nzira dzinoti dzinonyanya kuomeswa kana compostable. Asi mune dzimwe nguva nzira idzi dzinogona kunge dziri kuwedzera dambudziko remicroplastic. Tsvagiridzo yakaitwa nemasaenzi epaYunivhesiti yePlymouth kuUK yakawana kuti mabhegi akanyorwa se "biodegradable" anogona kutora makore kuti aparare, uye kunyangwe ipapo iwo anowanzo pwanyika kuita zvidimbu zvidiki kwete chikamu chavo chemakemikari. (Dzidza zvakawanda nezve nei biodegradables isingagadzirise dambudziko repurasitiki muchinyorwa chino naKelly Oakes.)
Zvakadini nekuchinja kumabhodhoro egirazi?
Kuchinjanisa mapurasitiki ekurongedza kunogona kubatsira kuderedza kuratidzwa - pombi mvura ine yakaderera mwero microplastics kupfuura mvura kubva mumabhodhoro epurasitiki. Asi zvaizovawo nemigumisiro yezvakatipoteredza. Nepo mabhodhoro egirazi ane chiyero chepamusoro chekudzokorora, vanewo yakakwirira yezvakatipoteredza tsoka pane epurasitiki uye mamwe mapeji anoshandiswa kune zvinwiwa zvakadai semabhokisi ezvinwiwa nemagaba ealuminium. Izvi zvinodaro nekuti kucherwa kwesilica, iyo girazi inogadzirwa, inogona kukonzeresa kukuvadza kwezvakatipoteredza, kusanganisira kuparara kwevhu uye kurasikirwa kwezvipenyu zvakasiyana-siyana. Kunyangwe neaya asiri epurasitiki midziyo, zvakaoma kutiza microplastics zvachose. Zvidzidzo zvinotungamirwa naSherri Mason kuPennsylvania State University zvakaona kuti havasipo chete mukati tap mvura, uko kusvibiswa kwakawanda kwepurasitiki kunobva kune zvipfeko zvembatya, asiwo gungwa munyu uye kunyange doro. Verenga zvakawanda pamusoro pekuti girazi kana plastiki iri nani kune zvakatipoteredza.
Pane chingaitwa here kuderedza microplastics?
Sezvineiwo, pane tariro. Vatsvagiri vari kugadzira akati wandei nzira dzekubatsira kubvisa kusvibiswa kwepurasitiki munharaunda yedu. Imwe nzira yave yekutendeukira kune fungi uye mabhakitiriya anodya papurasitiki, achiipwanya mukuita. Rudzi rwezvipembenene runogona kudya polystyrene rwakapawo imwe mhinduro. Vamwe vari kutarisa kushandisa nzira dzekuchenesa mvura kana mishonga yemakemikari inogona kubvisa microplastics.
