IAntarctica yayikade yaziwa “njengeyona ndawo icocekileyo emhlabeni.Kodwa ngoku, le ndawo ingcwele nayo iyangcoliswa.Ngokutsho kweCryosphere, abaphandi bafumene i-microplastics okokuqala ngqa kwiisampuli zekhephu ezivela e-Antarctica.iphepha ikomityi ifeni izinto ekrwada
Abaphandi baqokelele iisampulu zekhephu ezili-19 kwiindawo ezahlukeneyo ecaleni kweRoss Ice Shelf, eyona shelf inkulu yomkhenkce eAntarctica – iisampulu ezintandathu ukusuka kufutshane nesikhululo sophando kunye ne-13 eseleyo “kwiindawo ezikude ezinophawu oluncinci lomntu”.Isampulu nganye yavavanywa ubukho be-microplastics.
Okufunyenweyo kuthetha ukuba umonakalo wendalo obangelwa kungcoliseko lweplastiki unokunyuka ngokukhawuleza.Izazinzulu ziye zafumana i-microplastics kwintlenga yolwandle-nzulu, ulwandle kunye namanzi angaphezulu e-Antarctica, kodwa sisihlandlo sokuqala ukuba zifunyenwe kwiisampuli zekhephu.iphepha indebe fan fan
Abaphandi baqikelela ukuba kukho imithombo emibini ye-microplastics kwikhephu lase-Antarctica.Okokuqala, imisinga yomoya ithumela amasuntswana amawaka eekhilomitha ukusuka eAntarctica.Okwesibini, abantu baye bashiya umkhondo e-Antarctica, beza ne-microplastics kunye nabo.
Yintoni microplastic?Iza kuyichaphazela njani iAntarctica?
Iincinci zeplastiki ezingaphantsi kwe-5 millimeters ububanzi zibizwa ngokuqhelekileyo njenge "microplastics".Incinane kunokhozo lwerayisi kwaye ayinakubonwa ngeliso lenyama.Uninzi lwe-microplastics efunyenwe e-Antarctica yi-polyethylene terephthalate (PET), efumaneka ngokuqhelekileyo kwiibhotile zesiselo kunye nempahla.indebe yephepha ekrwada
Namhlanje, iimicroplastics zinokufunyanwa phezulu njengeMount Everest nakumazantsi olwandle.La masuntswana mancinane anokungena emzimbeni ngokutya, isiselo kunye nomoya.Uphononongo luchonge ubukho bazo kwigazi lomntu kunye nemiphunga.
Uphononongo lubonise ukuba i-microplastics inokubangela "umonakalo omkhulu kakhulu wendalo" e-Antarctica.Ukunyibilika kwe-cryosphere kunokwenzeka ukuba kukhawuleziswe xa i-microplastics ifunyenwe kwikhephu kunye nomkhenkce weentaba eziphakamileyo okanye imimandla ye-polar.IMicroplastics inokuba yi-ice nuclei emoyeni, ichaphazele ngakumbi imozulu.indebe yephepha umenzi wezinto ezikrwada
Ukongeza koku, ukungeniswa kwe-microplastics ngezinto eziphila elwandle kunokuchaphazela kakubi yonke ikhonkco le-Antarctic biotic.
“IMicroplastics inokuba nezinto eziyingozi ezincanyathiselwe kumphezulu wazo, njengesinyithi esinzima kunye ne-algae.Ezi zinto, ebezingeke zibekho kwezi ndawo zikude kakhulu nezikhuselweyo, zifikelela e-Antarctica ngesithuthi se-microplastics.”indebe yephepha yezinto ekrwada
Ngoko ke, ukwenzela ukunciphisa ingozi yeplastiki, ukunciphisa ukusetyenziswa kweemveliso zeplastiki, "iphepha endaweni yeplastiki" iyimfuneko.Okwangoku, omabini amaphepha asekhaya nangaphandle kunye namashishini okupakisha ajonga ukusetyenziswa kwephepha endaweni yokupakisha iplastiki, kwaye aphuhlise izitro zephepha, iimveliso ezibunjiweyo zepulp, iibhokisi zesiselo, iibhokisi zesidlo sasemini kunye nezinye iimveliso ezisekwe kwiphepha ukufaka isandla ekunciphiseni umhlaba. ukusetyenziswa kwezixhobo zeplastiki.pe iphepha indebe abalandeli
