Njengoko sonke sisazi, umkhondo weengxowa zeplastiki usasazeke phantse kuzo zonke iimbombo zehlabathi, ukusuka edolophini enengxolo ukuya kwiindawo ezingafikelelekiyo, kukho amanani amhlophe ongcoliseko, kwaye ungcoliseko olubangelwa ziingxowa zeplastiki luya lusiba lukhulu ngakumbi. Kuthatha amakhulu eminyaka ukuba ezi plastiki zithotywe isidima. Into ebizwa ngokuba yi-degradation kukutshintsha nje ubukho be-microplastic encinci. Ubungakanani bayo besuntswana bunokufikelela kwi-micron okanye nakwi-nanometer isikali, yenze umxube wamasuntswana eplastiki aneemilo ezahlukeneyo. Kudla ngokuba nzima ukuchaza ngeliso lenyama.
Ngokunyuka ngakumbi kwengqwalasela yabantu kungcoliseko lweplastiki, igama elithi "microplastic" liye lavela ngakumbi kwingqiqo yabantu, kwaye ngokuthe ngcembe latsala ingqalelo yazo zonke iinkalo zobomi. Ngoko ke yintoni microplastics? Ngokuqhelekileyo kukholelwa ukuba i-diameter ingaphantsi kwe-5 mm, ubukhulu becala ukusuka kwiincinci ezincinci zeplastiki ezikhutshwe ngokuthe ngqo kwimo engqongileyo kunye namaqhekeza eplastiki aveliswa kukuthotywa kwenkunkuma enkulu yeplastiki.
I-Microplastics incinci ngobukhulu kwaye kunzima ukuyibona ngeso lenyama, kodwa amandla abo okukhangisa anamandla kakhulu. Yakuba idityaniswe nezingcolisi ezikhoyo kwimekobume yaselwandle, iyakwenza ingqukuva yongcoliseko, kwaye iya kudada kwiindawo ngeendawo ezinemisinga yolwandle, ngakumbi Yandisa umda wongcoliseko. Ngenxa yokuba ububanzi be-microplastics buncinci, kunokwenzeka ukuba kufakwe izilwanyana elwandle, ezichaphazela ukukhula kwazo, ukuphuhliswa kunye nokuzala, kunye nokuphazamisa ukulingana kobomi. Ukungena emzimbeni wezinto eziphila elwandle, kwaye emva koko ukungena emzimbeni womntu ngekhonkco lokutya, kunempembelelo enkulu kwimpilo yabantu kwaye kusongela impilo yabantu.
Ngenxa yokuba ii-microplastics zithwala ungcoliseko, zikwabizwa ngokuba yi "PM2.5 elwandle". Ke ngoko, ikwabizwa ngokucacileyo ngokuba yi "PM2.5 kwishishini leplastiki".
Kwangoko ngo-2014, ii-microplastics zidweliswe njengenye yeengxaki ezilishumi ezingxamisekileyo zokusingqongileyo. Ngokuphuculwa kokuqonda kwabantu malunga nokukhuselwa kolwandle kunye nempilo yendalo yaselwandle, i-microplastics ibe yinto eshushu kuphando lwezenzululwazi zaselwandle.
I-Microplastics ikhona yonke indawo kule mihla, kwaye kwiimveliso ezininzi zendlu esizisebenzisayo, i-microplastics inokungena kwinkqubo yamanzi. Inokungena kwinkqubo yokujikeleza kokusingqongileyo, ingene elwandle isuka kwiifektri okanye emoyeni, okanye emilanjeni, okanye ingene emoyeni, apho amasuntswana e-microplastic emoyeni awela emhlabeni ngenxa yeziganeko zemozulu ezifana nemvula nekhephu, emva koko angene emhlabeni. , okanye Inkqubo yomlambo ingene kumjikelo webhayoloji, kwaye ekugqibeleni iziswe kwinkqubo yokujikeleza komntu ngumjikelo webhayoloji. Zikho kuyo yonke indawo emoyeni esiwuphefumlayo, kumanzi esiwaselayo.
I-Wandering microplastics ityiwa lula zizidalwa ezisezantsi zokutya. I-Microplastics ayikwazi ukugaywa kwaye inokubakho kuphela esiswini ngalo lonke ixesha, ithatha indawo kwaye ibangele ukuba izilwanyana zigule okanye zife; izidalwa ezisezantsi kwikhonkco lokutya ziya kudliwa zizilwanyana ezikumgangatho ophezulu. Umphezulu wekhonkco lokutya ngabantu. Inani elikhulu le-microplastics lisemzimbeni. Emva kokusetyenziswa komntu, la masuntswana amancinci angagayekiyo aya kubangela ingozi engalindelekanga ebantwini.
Ukunciphisa inkunkuma yeplastiki kunye nokunqanda ukwanda kwee-microplastics yimbopheleleko engenakuphepheka ekwabelwana ngayo uluntu.
Isisombululo kwi-microplastics kukunciphisa okanye ukuphelisa umthombo wongcoliseko ovela kwingcambu, ukwala ukusebenzisa iingxowa zeplastiki ezineplastiki, kwaye ungalahli inkunkuma yeplastiki okanye utshise; Lahla inkunkuma ngendlela emanyeneyo nengenangcoliseko, okanye ingcwabe nzulu; ukuxhasa "i-plastic ban" kwaye upapashe "i-plastic ban" imfundo, ukwenzela ukuba abantu baqaphele i-microplastics kunye nezinye izinto zokuziphatha eziyingozi kwindalo yendalo, kwaye baqonde ukuba abantu bahlobene ngokusondeleyo nendalo.
Ukuqala kumntu ngamnye, ngemigudu yomntu ngamnye, sinokwenza indalo esingqongileyo icoceke kwaye sinike inkqubo yojikelezo lwendalo umsebenzi ofanelekileyo.
