Antaragitika yahoze izwi nk '“ahantu hasukuye ku isi.Ariko ubu, aha hantu hera nabwo haranduye.Nk’uko ikinyamakuru The Cryosphere kibitangaza ngo abashakashatsi bavumbuye microplastique ku nshuro ya mbere mu ngero za shelegi zaturutse muri Antaragitika.impapuro igikombe cyabafana ibikoresho bibisi

Abashakashatsi bakusanyije ingero 19 z'urubura ahantu hatandukanye ku nkombe za Ross Ice Shelf, ahantu hanini cyane muri Antarctica - ingero esheshatu zaturutse hafi y’ikigo cy’ubushakashatsi naho 13 zisigaye ziva “ahantu hitaruye kandi zifite ibirenge bike”.Buri cyitegererezo cyageragejwe kugirango habeho microplastique.

Ubushakashatsi bivuze ko kwangiza ibidukikije byatewe n’umwanda wa plastike bishobora kwihuta.Abahanga mu bya siyansi bavumbuye microplastique mu nyanja y’inyanja, inyanja n’amazi yo hejuru muri Antaragitika, ariko ni ubwambere babonetse mu byitegererezo by’urubura.impapuro igikombe cyumufana

Abashakashatsi bavuga ko mu rubura rwa Antaragitika hari amasoko abiri ya microplastique.Ubwa mbere, umuyaga wohereje ibice kilometero ibihumbi muri Antaragitika.Icya kabiri, abantu basize ikirenge muri Antaragitika, bazana na microplastique.

Microplastique ni iki?Bizagira izihe ngaruka muri Antaragitika?

Ibice bya plastiki bitarenze milimetero 5 z'umurambararo byitwa "microplastique".Ni ntoya kuruta ingano z'umuceri kandi ntishobora kumenyekana n'amaso.Hafi ya microplastique iboneka muri Antaragitika ni polyethylene terephthalate (PET), ikunze kuboneka mu macupa y'ibinyobwa n'imyambaro.impapuro igikombe kibisi

Muri iki gihe, microplastique irashobora kuboneka gushika ku musozi wa Everest no gushika ku nyanja yimbitse.Utuntu duto duto dushobora kwinjira mu mubiri binyuze mu biryo, ibinyobwa n'umwuka.Ubushakashatsi bwerekanye ko bahari mumaraso yabantu nibihaha.

Ubushakashatsi bwerekanye ko microplastique ishobora gutera “kwangiza ibidukikije cyane” muri Antaragitika.Gushonga kwa kirisiyose birashoboka ko byihuta mugihe microplastique ibonetse mu rubura na barafu yimisozi miremire cyangwa uturere twa polar.Microplastique irashobora guhinduka nuclei mu kirere, bikagira ingaruka ku kirere.impapuro igikombe cyibikoresho bikora

Usibye ibi, kwinjiza microplastique n’ibinyabuzima byo mu nyanja birashobora no kugira ingaruka mbi ku ruhererekane rw’ibinyabuzima rwa Antaragitika.

“Microplastique irashobora kuba ifite ibintu byangiza bifatanye hejuru yabyo, nk'ibyuma biremereye na algae.Ibi bintu, bitari kuboneka muri ibi bidukikije cyane kandi birinzwe, bigera muri Antaragitika binyuze mu modoka ya microplastique. ”igikombe cyibikoresho

Kubwibyo, kugirango ugabanye ingaruka za plastiki, gabanya ikoreshwa ryibicuruzwa bya pulasitike, birakenewe "impapuro aho kuba plastike".Kugeza ubu, haba mu gihugu no mu mahanga impapuro n’inganda zipakira zirimo gukora ubushakashatsi ku mikoreshereze y’ipaki aho gupakira plastike, kandi zateje imbere ibyatsi, impapuro zakozwe mu bicuruzwa, ibisanduku by’ibinyobwa, agasanduku ka sasita n’ibindi bicuruzwa bishingiye ku mpapuro kugira ngo bigabanye isi yose yo gukoresha ibikoresho bya pulasitiki.pe abakunzi b'igikombe
