ukungena kumaseli

Usokhemisi uChristopher Zangmeister, umcwaningi oholayo kulolu cwaningo, uthe akwaziwa okwamanje ukuthi zinemiphumela emibi yini empilweni yabantu noma ezilwaneni, kodwa izinhlayiya ezingabonakali zitholakala ezigidini zezigidi kulo lonke ilitha lesiphuzo, ephawula ukuthi “kule minyaka eyishumi edlule. , ososayensi bathole izinto zepulasitiki nomaphi lapho bebheka khona endaweni ezungezile.”

Futhi, uZangmeister wachaza ukuthi ngokuhlola ngaphansi kwamachibi aneqhwa e-Antarctica, kwatholakala izinhlayiya ezincane zepulasitiki ezinkulu kune-nanometer ezingaba ngu-100, okusho ukuthi zazingencane ngokwanele ukungena esitokisini futhi zibangele izinkinga zomzimba, echaza ukuthi imiphumela yocwaningo olusha. ngoba ama-nanoparticles [atholakala ezinkomishini zekhofi] ayemancane kakhulu futhi ayengangena esitokisini, okwakungase kuphazamise ukusebenza kwawo.”

Isifundo samaNdiya

Ucwaningo olufanayo, olwenziwa yi-Indian Institute of Technology ngo-2020, lwathola ukuthi isiphuzo esishisayo enkomishini elahlwayo sinesilinganiso sezinhlayiya ze-microplastic ezingama-25000, kanye namaminerali afana ne-zinc, lead kanye ne-chromium emanzini. Abacwaningi baseMelika bakholelwa ukuthi imiphumela yavela kulwelwesi olufanayo lwepulasitiki.

Abacwaningi baseMelika baphinde bahlaziya izikhwama zenayiloni ezihloselwe ukupakisha ukudla okufana nesinkwa, okungamashidi epulasitiki asobala abekwe kumapani okubhaka ukuze kwakhiwe indawo enganamathele evimbela ukulahlekelwa umswakama. Bathola ukuthi ukugcwala kwama-nanoparticles akhishwa emanzini enayiloni ebangeni lokudla kwakuphakeme ngokuphindwe kasikhombisa kunasenkomishini yesiphuzo esetshenziswa kanye.

U-Zangmeister waphawula ukuthi okutholwe yilolu cwaningo kungasiza imizamo yokuthuthukisa ukuhlola okunjalo ukunciphisa noma yimiphi imiphumela emibi empilweni yabantu.
