Ngenxa yesimo esingesisekelo se-Fibers ye-Glass, bayehlela izingcezwana ezimfushane ze-fiber. Ngokwesivivinyo sesikhathi eside esenziwe yi-World Health Organisation kanye nezinye izinhlangano, izicucu ezinobubanzi bezinto ezineminyaka engaphansi kwezingu-3 kanye nokulinganiselwa kwezici ezingaphezu kuka-5: 1 kungafakwa ujule emanzini. Imicu yengilazi esivame ukuyisebenzisa ngokuvamile imvamisa ama-microns angama-3 ububanzi, ngakho-ke asikho isidingo sokukhathazeka ngokweqile ngezingozi zamaphaphu.
EVIVO Disolution Study ofIzicucu ze-Glassbakhombisile ukuthi ama-microcracks akhona ebusweni bemicu yengilazi ngesikhathi sokucutshungulwa azokwanda futhi ajule ngaphansi kokuhlaselwa kwamanzi abuthakathaka, anciphise amandla awo angaphezulu komhlaba, akhohlise amandla okuwohloka kwawo. Ucwaningo selukhombisile ukuthi imicu yengilazi ichithwa ngokuphelele emaphashini ezinyangeni eziyi-1,2 kuye kwezi-3.
Ngokusho kwamaphepha okucwaninga kwangaphambilini, ukuvezwa kwesikhathi eside (ngaphezu konyaka owodwa kuzo zombili lezi zigameko) zamagundane namagundane aqukethe imicu ephakeme ye-Flibrosis (izikhathi ezingaphezu kwengxenye yokukhiqiza ngaphakathi kwe-Pleura ezifuywayo zembula amaphaphu amaphaphu. Ucwaningo lwethu lwezeMpilo lwabasebenzi embonini ye-fiber yengilazi okukhulunywa ngalo alutholanga ukwanda okukhulu kwezigameko ze-pneumoconiosis, umdlavuza wamaphaphu, noma uthole ukuthi umsebenzi wamaphaphu, kodwa wathola ukuthi umsebenzi wamaphaphu othe xaxa uncishiswe uma kuqhathaniswa nenani labantu.
NokhoIzicucu ze-Glassbona ngokwabo awenzi ingozi empilweni, ukuxhumana okuqondile nemizwa yengilazi kungadala ukucasuka esikhunjeni namehlo, futhi ukuphefumula kothuli okuqukethe imicu yengilazi kungacasulwa izindinyana zamakhala, i-trachea kanye nomphimbo. Izimpawu zokucasuka zivame ukungacacisi futhi zisikhashana futhi zingafaka ukulunywa, ukukhwehlela noma ukuhlasela. Ukuchayeka okukhulu kwe-strorne fiberglass kungandisa i-asthma noma izimo ezifana ne-bronchitis. Ngokuvamile, izimpawu ezihambisana nazo ziyazethela zona lapho umuntu oveziwe esuka emthonjeni weijibhaisikhathi esithile.
