ukungena kwiiseli

Usokhemikhali uChristopher Zangmeister, umphandi okhokelayo kolu phando, wathi akukaziwa okwangoku ukuba zinefuthe elibi empilweni yabantu okanye kwizilwanyana, kodwa amasuntswana abona ngemicroscope akhoyo kwiibhiliyoni kwilitha nganye yesiselo, ephawula ukuba “kwishumi leminyaka elidluleyo. , izazinzulu ziye zafumana izinto zeplastiki naphi na apho zijonga khona kwimekobume.”

Kwakhona, uZangmeister wachaza ukuba ngokuphonononga emazantsi amachibi anomkhenkce e-Antarctica, kwafunyanwa amasuntswana e-microplastic amakhulu kune-nanometers emalunga ne-100, okuthetha ukuba ayengencinci ngokwaneleyo ukuba angangena kwiseli kwaye abangele iingxaki zomzimba, echaza ukuba iziphumo zophononongo olutsha. Ngenxa yokuba ii<em>nanoparticles [ezifumaneka kwiikomityi zekofu] zazincinane kakhulu yaye zinokungena ngaphakathi kwesisele, nto leyo eyayinokuphazamisa ukusebenza kwayo.”

Isifundo samaNdiya

Uphononongo olufanayo, olwenziwe yi-Indian Institute of Technology ngo-2020, lwafumanisa ukuba isiselo esishushu kwikomityi elahlayo iqulethe umndilili wamasuntswana angama-25000 e-microplastic, kunye neeminerali ezinjengezinc, ilothe kunye nechromium emanzini. Abaphandi baseMelika bakholelwa ukuba iziphumo zivela kwilayini yeplastiki efanayo.

Abaphandi baseMelika baphinde bahlalutya iingxowa zenayiloni ezilungiselelwe ukupakisha ukutya okufana nesonka, eziziiplastiki ezicacileyo ezibekwe kwiipani zokubhaka ukuze zenze indawo engabonakaliyo ekhusela ukulahlekelwa ngumswakama. Baye bafumanisa ukuba ukuxinana kwee-nanoparticles ezikhutshiweyo kumgangatho wokutya okushushu kumanzi enayiloni kuphezulu ngokuphindwe kasixhenxe kunoko kwiikomityi zesiselo ezisetyenziswa kanye.

U-Zangmeister uqaphele ukuba iziphumo zophononongo zinokunceda iinzame zokuphuhlisa uvavanyo olunjalo ukunciphisa naziphi na iziphumo ezibi kwimpilo yabantu.
