Nokuba kususela kwiilwandle ezinzulu ukuya kwiintaba ezinde, okanye emoyeni nasemhlabeni ukuya kwikhonkco lokutya, inkunkuma ye-microplastic sele ikhona phantse kuyo yonke indawo eMhlabeni. Ngoku, uphando olongezelelekileyo luye lwabonisa ukuba iiplastiki ezincinci “zingene” egazini labantu.
I-Micro Iiplastiki zafunyanwa egazini lomntu okokuqala!
Ngokwesiqhelo, inkunkuma yeplastiki engaphantsi kwe-5mm ububanzi ibizwa ngokuba yi "microplastics", kwaye ubungakanani bayo obuncinci kakhulu benza kube nzima ngathi ukuyibona ukuba ikhona.
Kutshanje, uphando olupapashwe kwijenali ye-international environment lubonisa ukuba izazinzulu zifumanise ungcoliseko lweplastiki encinci egazini lomntu okokuqala. Izifundo zangaphambili zifumanise iiplastiki ezincinci emathunjini, i-placenta yeentsana ezingekazalwa kunye nendle yabantu abadala kunye neentsana, kodwa iiplastiki ezincinci azikaze zifunyanwe kwiisampuli zegazi.
Olu phononongo luhlolisise iisampuli zegazi ezivela kubantu abangama-22 abaziingcali abasempilweni abangaziwayo, lwaza lwafumanisa ukuba i-77% yeesampuli zazine-microplastics enomlinganiselo we-1.6 micrograms kwi-milliliter nganye.
Kuvavanywe iintlobo ezintlanu zeplastiki: i-polymethylmethacrylate (PMMA), i-polypropylene (PP), i-polystyrene (PS), i-polyethylene (PE) kunye ne-polyethylene terephthalate (PET).
I-PMMA, eyaziwa ngokuba yi-acrylic okanye i-plexiglass, isetyenziswa kakhulu xa kujongwa izixhobo ze-elektroniki kunye nezixhobo zokukhanyisa.
I-PP isetyenziswa kakhulu kwiibhokisi zokutya, kwiibhokisi zokugcina ukutya okutsha kunye neebhotile zobisi.
I-PS isetyenziswa kakhulu kwizixhobo zokupakisha ukutya ezilahlwayo.
I-PE idla ngokusetyenziselwa ukupakisha iifilimu kunye neengxowa zeplastiki, ezifana neengxowa zokugcina izinto ezintsha kunye neefilimu zokugcina izinto ezintsha.
I-PET idla ngokusetyenziselwa ukubonakala kweebhotile zamanzi aneminerali, iibhotile zeziselo kunye nezixhobo ezahlukeneyo zasekhaya.
Iziphumo zibonise ukuba malunga nesiqingatha seesampuli zegazi zibonise intsalela yeplastiki yePET, ngaphezulu kwesithathu seesampuli zegazi ziqulethe iPS kwaye malunga nekota yeesampuli zegazi ziqulethe iPE.
Okumangalisa nangakumbi kukuba abaphandi bafumene iintlobo ezintathu ezahlukeneyo zeplastiki ezincinci kwisampulu yegazi.
Amanqanaba eplastiki eesampuli zegazi ezingama-22 ahlulwe ngohlobo lwepolymer
Iiplastiki ezincinci zingena njani egazini?
Uphando lubonisa ukuba ezi plastiki zincinci zinokungena emzimbeni womntu ngomoya, ngamanzi okanye ngokutya, okanye nge-toothpaste ethile, i-lipstick kunye ne-tattoo inki. Ngokwethiyori, amasuntswana eplastiki anokuthuthwa ngegazi ukuya kumalungu ahlukeneyo emzimbeni wonke.
Abaphandi bathi kusenokwenzeka ukuba kukho ezinye iintlobo zeeplastiki ezincinci egazini, kodwa abazange babone amasuntswana amakhulu kunobubanzi benaliti yokuvavanya kolu phononongo.
Nangona impembelelo yeeplastiki ezincinci kwimpilo yabantu ingacacanga, abaphandi bakhathazekile kukuba iiplastiki ezincinci ziya kubangela umonakalo kwiiseli zabantu. Ngaphambili, amasuntswana ongcoliseko lomoya aye abonakala engena emzimbeni womntu kwaye abangela izigidi zabantu abafa ngaphambi kwexesha minyaka le.
Iphi indlela yokuphuma kongcoliseko lweplastiki?
I-Geotegrity yaseMpuma EkudeIzitya zokukhusela okusingqongileyo zePulp zifumene udumo olukhulu kwimarike ngenxa yeempawu zazo ezahlukileyo kunye nendlela yokukhusela okusingqongileyo yoluhlu olubanzi lwezinto ezikrwada,ukonakala okulula, ukuphinda kusetyenziswe kunye nokuhlaziywa, nto leyo eyenza ukuba ibonakale phakathi kwazo zonke iintlobo zezinto ezithatha indawo yeplastiki. Iimveliso zinokubola ngokupheleleyo kwimo yendalo zingadlulanga iintsuku ezingama-90, kwaye zingasetyenziselwa ukwenza umgquba emakhaya nakwimizi-mveliso. Izinto eziphambili emva kokubola ngamanzi kunye ne-carbon dioxide, ezingayi kuvelisa intsalela yenkunkuma kunye nongcoliseko.
Mpuma Ekude. Iimveliso zokupakisha ukutya (izinto zokutya) ezikhuselweyo yiGeotrgrity zisebenzisa ingca yezolimo, irayisi kunye nengca yengqolowa,umdiza weswekilekunye neengcongolo njengezinto zokwenza izinto ezingenangcoliseko kwayeukonga umbaneUkuveliswa nokurisayikilishwa kwamandla acocekileyo. Uphumelele isiqinisekiso se-9000 samazwe ngamazwe; isiqinisekiso sokukhuselwa kwendalo se-14000, uphumelele uvavanyo lwamazwe ngamazwe lwe-FDA, i-UL, i-CE, i-SGS kunye neSebe lezeMpilo neNtlalontle laseJapan e-United States nakwi-European Union, ufikelele kumgangatho wehlabathi wococeko wokupakisha ukutya, kwaye uphumelele isihloko sokuhlonipha "imveliso yokuqala yeFujian kwishishini lokuvelisa".
Njengomngcipheko wehlabathi, ungcoliseko lweplastiki luyisongelo esikhulu kwimpilo yabantu ngohlobo lweeplastiki ezincinci kunye neekhemikhali ezinobungozi.I-Far East Geotrgrityunesibindi sokuthatha uxanduva lwenkampani kuluntu, ukunamathela kwisayensi netekhnoloji entsha kunye nokukhuthaza injongo yetafile eluhlaza! Ukushiya ihlabathi elicocekileyo nelihle kwizizukulwana ezizayo, iFar East Geotegrity iya kuqhubeka nokusebenza kunye nokusebenzisana nabantu abanolwazi kushishino ngeenjongo kunye nesenzo sokulwa ngokukhutheleyo ungcoliseko lweplastiki, ukwenza imizamo engapheliyo yokukhuthaza uphuhliso oluzinzileyo lwabantu kunye nokwakha uluntu lobomi phakathi kwabantu kunye nendalo.
