Zithini iziphumo zefiberglass emzimbeni womntu?

Ngenxa yokuba imicu yeglasi ibuthathaka, iyaqhekeka ibe ziingceba zemicu emifutshane. Ngokwezilingo ezinde ezenziwe yi-World Health Organisation kunye neminye imibutho, imicu enobubanzi obungaphantsi kwe-3 microns kunye nomlinganiselo wobume obungaphezulu kwe-5:1 inokuphefumlelwa nzulu emiphungeni yomntu. Imicu yeglasi esiyisebenzisa rhoqo ibanzi kune-3 microns ububanzi, ngoko ke akukho mfuneko yokukhathazeka kakhulu ngeengozi zemiphunga.

Izifundo zokunyibilika emzimbeniiifayibha zeglasizibonise ukuba ii-microcracks ezikhoyo kumphezulu weefayibha zeglasi ngexesha lokucubungula ziya kwanda kwaye zinzulu xa zihlaselwa zi-alkaline encinci, zinyuse indawo yazo yomphezulu kwaye zinciphise amandla eefayibha zeglasi, ngaloo ndlela zikhawulezisa ukuwohloka kwazo. Izifundo zibonise ukuba iifayibha zeglasi ziyanyibilika ngokupheleleyo emiphungeni kwiinyanga ezili-1.2 ukuya kwezi-3.

Ngokwamaphepha ophando angaphambili, ukuvezwa ixesha elide (ngaphezulu konyaka omnye kwiimeko zombini) kweempuku kunye neempuku emoyeni oqulethe ubuninzi beefayibha zeglasi (ngaphezulu kwekhulu leemeko zemveliso) akuzange kube nefuthe libalulekileyo kwi-lung fibrosis okanye ukwanda kwethumba, kwaye ukufakwa kweefayibha zeglasi ngaphakathi kwe-pleura yezilwanyana kubonise i-fibrosis emiphungeni. Uphando lwethu lwezempilo lwabasebenzi kwishishini lefayibha yeglasi olukhankanyiweyo alufumananga ukwanda okukhulu kweziganeko ze-pneumoconiosis, umhlaza wemiphunga, okanye i-pulmonary fibrosis, kodwa lufumanise ukuba umsebenzi wemiphunga wabasebenzi abakhankanyiweyo unciphile xa kuthelekiswa noluntu ngokubanzi.

Nangonaiifayibha zeglasingokwazo azibeki mngcipheko kubomi, ukudibana ngqo neefayibha zeglasi kunokubangela imvakalelo enamandla yokucaphuka eluswini nasemahlweni, kwaye ukuphefumla amasuntswana othuli aneefayibha zeglasi kunokucaphuka imibhobho yempumlo, i-trachea, kunye nomqala. Iimpawu zokucaphuka zihlala zingabalulekanga kwaye zezexeshana kwaye zinokubandakanya ukurhawuzelela, ukukhohlela okanye ukuphefumla. Ukuchatshazelwa kakhulu kwi-fiberglass emoyeni kunokwenza imeko ye-asthma okanye efana ne-bronchitis ibe mandundu. Ngokubanzi, iimpawu ezinxulumene noko ziyaphela xa umntu ochatshazelweyo eshiya umthombo wesifo.i-fiberglasskangangexesha elithile.
