Ivumburwa rya tellurium ritera ikibazo: ku ruhande rumwe, birakenewe ko hajyaho umubare munini w’ingufu z’icyatsi kibisi, ariko kurundi ruhande, ubucukuzi bw’amabuye y'agaciro bushobora kwangiza cyane ibidukikije.
Ni ubuhe bucuruzi hagati yo kurema ingufu z'icyatsi no gusenya ubucukuzi
Raporo yakozwe mu isuzuma ry’ikoranabuhanga rya MIT, abashakashatsi basanze munsi y’inyanja ibyuma bidasanzwe, ariko ahanini bazanye kuvumbura ikibazo gikomeye: mugikorwa cyo gukoresha umutungo kamere, aho tugomba gushushanya.
Nk’uko BBC ikomeza ibivuga, abahanga mu bya siyansi bavumbuye ubutunzi budasanzwe cyane bw'isi mu misozi y'inyanja ku bilometero 300 uvuye ku nkombe z'izinga rya kanari. Hafi ya metero 1 000 munsi yubuso bwinyanja, urutare rufite uburebure bwa santimetero ebyiri zifungiye mumisozi yo munsi yinyanja rurimo icyuma kidasanzwe cyitwa tellurium hejuru yinshuro 50 000 000 zubutaka.
Tellurium irashobora gukoreshwa muri zimwe mu ngirabuzimafatizo zikoresha izuba ku isi, ariko kandi ifite ibibazo bigoye kuyikoresha, nk'ibyuma byinshi bidasanzwe-isi. Uyu musozi urashobora gutanga toni 2,670 za tellurium, bingana na kimwe cya kane cy’ibicuruzwa byose ku isi nk'uko umushinga uyobowe na Bram Murton ubitangaza.
Ntabwo aribwo bwa mbere hagaragaye ubucukuzi bw'amabuye y'agaciro adasanzwe. Ibyuma byose bizwi ko bibaho mu rutare munsi yinyanja, kandi amashyirahamwe amwe n'amwe yerekanye ko ashishikajwe no kuyacukura. Isosiyete Nautilus Minerals, isosiyete yo muri Kanada, yabanje guhangana na guverinoma, ariko ubu irimo gukora ibishoboka byose kugira ngo ikure umuringa na zahabu ku nkombe za Papua bitarenze mu mwaka wa 2019. Ubushinwa burimo kwiga cyane uburyo bwo gucukura amabuye y'agaciro munsi y’inyanja y'Ubuhinde, ariko kugeza ubu gutangira kumugaragaro. Amikoro yo mu nyanja arashimishije, kandi ubushakashatsi bwacu kuri ubu ku mashanyarazi n’ingufu zisukuye bwaguye icyifuzo cy’amabuye adasanzwe n’amabuye y'agaciro. Ubu umutungo wubutaka urahenze kubikoresha, ariko kugera kubutunzi buva munsi yinyanja bisa nkibishobora kuzuza ingufu zikenerwa ningufu zisukuye mugihe kiri imbere. Kandi biragaragara ko abitezimbere bashobora kubona inyungu nini.
Ariko paradox nuko ubu hari intiti nyinshi zihangayikishijwe no kwangiza ibidukikije byiyi gahunda. Mu ntangiriro z'uyu mwaka, nk'urugero, isesengura ry’ibizamini byacukuwe mu nyanja byerekanaga ko n'ibigeragezo bito bishobora kwangiza urusobe rw'ibinyabuzima byo mu nyanja. Ubwoba nuko ibikorwa byinshi bizaganisha ku kurimbuka gukomeye. Kandi ntibisobanutse niba urusobe rw'ibinyabuzima rwahungabanye, ni gute ruzatera ingaruka mbi, ndetse rushobora kubangamira imiterere y'ikirere cyo mu nyanja cyangwa gutandukanya karubone.
Ubuvumbuzi bwa Tellurium butera ikibazo gihungabanya umutekano: ku ruhande rumwe, birakenewe ko hajyaho ingufu nyinshi z’ingufu z’icyatsi, ariko ku rundi ruhande, ubwo bucukuzi bw’amabuye y'agaciro bushobora kwangiza ibidukikije cyane. Ibi bitera kwibaza niba inyungu zambere ziruta ingaruka zishobora guturuka nyuma. Gusubiza iki kibazo ntabwo byoroshye, ariko kubitekerezaho biduha ubushishozi bwo kumenya niba koko twiteguye gucukumbura agaciro kabo.
