Uyazi ukuthi ngaso sonke isikhathi uma uphuza amanzi ebhodlweni lepulasitiki ngamanzi amaminerali, ingabe ugwinya izinhlayiya zepulasitiki emicroscopic? Ucwaningo olwenziwe yiNew York University ngonyaka we-2018 luveze ukuthi izingcezu ezincane zepulasitiki zikhona ku-90% amasampula aqoqwe kusuka kumikhiqizo yamanzi ethandwa kakhulu emhlabeni.
Amanzi aseKorea avela ngesisombululo esiyingqayizivele sokuhlunga ama-microplastics kusuka kumanzi asemabhodleleni ukuze kuncishiswe ukungcoliswa kwama-polther aphazamisa ama-polymers kusukela ngo-2019, lapho kuqala ukuphenywa.
INyuvesi yaseNew York yenze ucwaningo namabhodlela angama-259 epakishe amanzi ayi-11 zemikhiqizo ehlukahlukene, eqoqwe njengamasampula avela emazweni ayisishiyagalolunye - I-Indonesia, eSyxa, Thailand kanye ne-United States. Ngemuva kokuthi imiphumela yocwaningo yenziwe emphakathini, iWorld Health Organisation (WHO) Ikhiphe umbono wokuthi izingozi ezingaba khona ezihambisana nokuba khona kwezinhlayiya zepulasitiki emanzini okuphuza amanzi. Ucwaningo luveze ukuthi ngokwesilinganiso, umuntu angasebenzisa izinhlayiya ezingama-2000 ezincane, ezingaba ngu-5 amagremu epulasitiki ngesonto.
Elula, kepha umklamo oyingqayizivele wesembozo sebhodlela lamanzi wangempela, elilungele cishe wonke amabhodlela epulasitiki, angasindisa izigidi zabantu ezinkingeni zempilo ezibangelwa yilezi zingcola ezibangelwa yilezi zingcola ezibangelwa yilezi zingcola ezibangelwa yilezi zingcola ezibangelwa yilezi zingcola ezibangelwa yilezi zingcola ezibangelwa yilezi zingcola ezibangelwa yilezi zingcola ezibangelwa ukungcoliswa kwalokhu kungcoliswa. Le mbozo iyakwazi ukuhlunga izinhlayiya ezincane zepulasitiki ezifika ku-0,005 mm.
Isembozo sokuhlunga samanzi sangempela singahlungwa cishe amalitha ayi-120 amanzi. Uma ngokwesilinganiso, umuntu uphuza amalitha amabili amanzi ngosuku, khona-ke i-cap enjalo izohlala izinyanga ezimbili. Kodwa-ke, kufanele ihlanzwe, ukuwasha ngaphansi kwamanzi okugeleza ukuze kufinyelelwe impilo engcono yesevisi, futhi kugcinwe endaweni eyomile lapho ingasetshenziswa. Inkampani futhi ihlinzeka ngecala lokugcina lokuhlunga.
Amanzi angempela akhiphe umkhiqizo wawo wokuqala ngoJuni 2020 futhi athola izibuyekezo ezinhle. Ngenyanga efanayo, amanzi angempela athule ukugcwala kokukhiqizwa kwabantu abaningi futhi athole uxhaso.
Njengamanje, inkampani ilungiselela ukuthekelisa izihlungi zayo ezihlukile zesembozo esinamabhodlela eJapan naseTaiwan. Ngokusho kwabamele inkampani,
Umbuzo we-microplastic emanzini anamabhodlela angabi kakhulu kunaseKorea. Eminye imikhiqizo phesheya inezinhlayiya ezifika ku-10,000 ze-microplasty ngelitha lamanzi. Njengoba ukufunwa kwabo kuphezulu, silungiselela ukungena kakhulu emakethe yaphesheya.
Umkhiqizo wamanzi wangempela uthole "isitifiketi sokungabikho kwezinto eziyingozi" ngemuva kokuhlolwa kwi-KORAN Institute of Tests and Research. Ngaphezu kwalokho, ngenxa yezivivinyo ezenziwa yiSikhungo saseKorea ukuze kwakhiwe endaweni yokuphila, kwaqinisekiswa ukuthi akuqukethe iBisphenol A *.
* I-Bisphenol A (BPA) ingenye yezinto ezisetshenziswa kakhulu ekukhiqizweni kwezinto ezifunwa nsuku zonke. Okokuqala, kuvame ukuba khona njengengxenye yamapulasitiki, kufaka phakathi ukufakwa kwepulasitiki lapho kugcinwa khona ukudla. Le nto ibhekisela kumakhemikhali abhubhisa uhlelo lwe-endocrine futhi ane-epigenetic ubuthi.
