Njengoko sonke sazi, umkhondo weengxowa zeplastiki usasazelwe phantse kuzo zonke iikona zehlabathi, ukusuka kwi-noisy dontown kwiindawo ezingcolisekileyo, kukho ungcoliseko olubi, kunye nongcoliseko olubangelwa ziingxowa zeplastiki lukhumbula ngakumbi kwaye lubaluleke ngakumbi. Kuthatha amakhulu eminyaka yezi prografiki ukuba inciphise. I-SO-ebizwa ngokuba kukonakaliswa kukutshintsha ubukho bemicroplastic encinci. Ubungakanani bayo bungafikeleli kwimifanekiso yeMicron okanye i-nanometer isikali, senza umxube we-heterogeneous amasuntswana eplastiki enemilo eyahlukeneyo. Kuhlala kunzima ukuxelela ngamehlo.
Ngokukodwa ukwanda kwengqwalaselo yabantu ukungcoliswa kweplastiki, igama elithi "i-microplastic" libonakale ekuqondisweni kwabantu nangakumbi, kwaye ngokuthe ngcembe latsala ingqalelo yazo zonke iindlela zobomi. Ke zeziphi ii-microplastics? Kuyakholelwa ngokubanzi ukuba ububanzi bungaphantsi kwe-5 mm, ubukhulu becala basuswe ngokuthe ngqo kwindalo kunye namaqhekeza eplastiki oveliswe kukudalwa kweplastiki enkulu.
Imicroplastics incinci ngokobukhulu kwaye kunzima ukubona ngamehlo, kodwa amandla abo e-Adsorption yomelele kakhulu. Nje ukuba zidityaniswe kunye nongcoliseko olukhoyo kwindawo yolwandle, iya kwenza indawo yongcoliseko, kwaye iya kubhabha kwiindawo ngeendawo zolwandle, yandisa ngakumbi ubungakanani bongcoliseko. Kuba ububanzi bemicroplastics buncinci, kunokubakho ukungeniswa kwezilwanyana elwandle, ekuchaphazeleni ukukhula kwabo, ukuphuculwa nokuveliswa kwakhona, kunye nokuphazamisa ibhalansi yobomi. Ukungena emzimbeni wezinto eziphilayo zaselwandle, emva koko ungene emzimbeni womntu ngekhonkco lokutya, inefuthe elikhulu kwimpilo yabantu kwaye isoyikise impilo yabantu.
Kungenxa yokuba i-microplastics ingabathwali bongcoliseko, nabo babizwa ngokuba "PM2.5 elwandle". Ke ngoko, kucacisiwe ngokucacileyo ukuba "nge-PM2.5 kwiShishini lePlastito".
Ukuqala kuka-2014, ii-microplastics zidweliswe njengenye yeengxaki ezilishumi ezingxamisekileyo kwindalo. Ngokuphuculwa kokwaziswa kwabantu kukhuseleko lwaselwandle kunye neMpilo yaseMarine yezeNdalo, i-microplassics ibe ngumcimbi oshushu kuPhando lwaselwandle.
I-microplastics ikwindawo yonke kwezi ntsuku, kwaye kwiimveliso ezininzi zasekhaya esizisebenzisayo, i-microplastics inokufika kwinkqubo yamanzi. Ingafaka inkqubo yokusingqongileyo yendalo esingqongileyo, faka ulwandle ukusuka kwiifektri okanye umoya, okanye imilambo, okanye ifake umhlaba, kwaye ingeniswe umhlaba, kwaye ekugqibeleni waziswa kwinkqubo yendalo. Bakho kuyo yonke indawo emoyeni esiwuphefumlayo, emanzini esisela.
Ii-microplastics ze-Wicroplastics zityiwa ngokulula zizilwanyana zokutya eziphantsi. I-microplastics ayinakutyiwa kwaye inokubakho kuphela esiswini ngalo lonke ixesha, ibeka indawo kwaye ichaphazele izilwanyana ukuba igule okanye ifa; Izidalwa ezisezantsi kwekhonkco lokutya ziya kutyiwa zizilwanyana eziphezulu. Umphezulu wekhonkco lokutya ngabantu. Inani elikhulu le-microplastics lisemzimbeni. Emva kokusetyenziswa kwabantu, la masuntsu amancinci anomdla aza kubangela ingozi engalindelekanga ebantwini.
Ukunciphisa inkunkuma yeplastiki kunye nokuphelisa ukusasazeka kweecroplastics luxanduva olungenakuthelekiswa nanto lwabantu.
Isisombululo kwii-microplastics kukunciphisa okanye ukuphelisa umthombo wongcoliseko ovela kunobangela wengcambu, ungavumi ukusebenzisa iingxowa zeplastiki ezinamaplasitiki, kwaye ungachithi inkunkuma yeplastiki okanye uyitshizi; Ukulahla inkunkuma kwindawo engenamanyanisiweyo neyongcoliseko, okanye ukungcwaba ngokunzulu; Inkxaso "Ukuvalwa kweplastiki" kwaye upapasha "imfundo" yeplastiki, ukuze abantu balumkise ii-microsplastics kunye nezinye izinto ezinobungozi kwindalo.
Ukuqala kumntu ngamnye, ngokusebenzisa eyakho, sinokwenza isicoci sendalo kwaye sinike inkqubo yokujikeleza kwendalo.
