Ngemizamo eyenziwayo yokuvimbela izinhlamvu ezisekelwe kumthofu njengengozi engaba yingozi empilweni nasemvelweni, ososayensi babika ubufakazi obusha bokuthi enye into eyinhlokobullets - tungsten- kungase kungabi esikhundleni esihle Umbiko, othole ukuthi i-tungsten inqwabelana ezakhiweni ezinkulu zamasosha omzimba ezilwaneni, uvela kujenali ye-ACS.Ucwaningo Lwekhemikhali ku-Toxicology.

UJose Centeno kanye nozakwabo bachaza ukuthi ama-tungsten alloys afakwe esikhundleni somthofu wezinhlamvu nezinye izikhali. Kwaba umphumela wokukhathazeka ngokuthi umthofu ophuma ezinhlamvini ezisetshenzisiwe ungalimaza izilwane zasendle lapho uncibilika emanzini enhlabathini, emifudlaneni nasemachibini. Ososayensi babecabanga ukuthi i-tungsten yayingenabo ubuthi uma kuqhathaniswa, futhi ithatha indawo “eluhlaza” yomthofu. Ucwaningo lwakamuva luphakamise okuhlukile, futhi ngamanani amancane e-tungsten asetshenziswa ezinqulwini nasemadolweni okwenziwa, iqembu likaCenteno lanquma ukuqoqa ulwazi olwengeziwe nge-tungsten.

Bengeze amanani amancane enhlanganisela ye-tungsten emanzini okuphuza amagundane aselabhorethri, asetshenziswa njengezindawo zokumbelela abantu ocwaningweni olunjalo, futhi bahlola izitho nezicubu ukuze babone ukuthi i-tungsten yaphelelaphi. Ukugxila okuphezulu kakhulu kwe-tungsten kwakusebeni, esinye sezingxenye eziyinhloko zesimiso sokuzivikela komzimba, namathambo, isikhungo noma "umnkantsha" wawo umthombo wokuqala wawo wonke amangqamuzana amasosha omzimba. Bathi, ucwaningo olwengeziwe luzodingeka ukuze kutholwe ukuthi yimiphi imiphumela, uma ikhona, i-tungsten engaba nayo ekusebenzeni kwamasosha omzimba.
