Ukubonakaliswa kwe- asbestos enobuthi kunokufaka isandla kwiimpawu zokuzimela, kunokubeka isiseko sezifo ezizenzekelayo ezizenzekelayo njenge-rheumatoid arthritis kunye ne-multiple sclerosis, ngokutsho kwiphando elipapashwe kwiphepha likaJanuwari 2005 lwengxelo ye-Environmental Review Perspectives (EHP).
Abaphandi bavavanya abahlali abangama-50 baseLibby, eMontana-idolophu engcoliswe yi-asbestos-kwaye bafumene amathuba okuba babe neklasini yamanqanaba abo kwigazi labo kuneqela elilawulayo.
Ubuninzi beempawu zezinto eziphilayo, ezibizwa ngokuba yi-ANAs, zifumaneka rhoqo kubantu abaxhomekeke kwiimpawu zokuzikhusela komzimba ngenxa yokuvuvukala kwiisisu zabo zomzimba.
Abaphandi bafumene ukuba ii-ANA zenzeke kwi-28.6% ngokuphindaphindiweyo kwiisampuli zeLibby kunezolawulo. Ukongezelela, abantu abaye bavelelwa kwi-asbestos iminyaka engaphezu kwemihlanu babekho ukuphakama okuphezulu kwe-ANA kunezo ezingabonakaliyo. Kwabahlali baseLibby bavavanywa, i-76% yayineengxaki ze-asbestos ezinxulumene nemiphunga, kwaye abo abaneengxaki zamaphaphu ezinzulu babe neendawo eziphezulu zokuhamba kwamanqanaba.
Kuthetha ukuba yonke idolophu yaseLibby yachongwa njengeSiza seSizwe soPhambili kweziNcwadi zoLuntu ngo-2002, emva kweemigodi zemigodi ye-vermiculite yonakalise i-mine, indawo yokucubungula, kunye nezindlu ezininzi, izakhiwo kunye neepropati kwidolophu ene-amphibole asbestos.
"Ngokubonisa ubudlelwane phakathi kokuchasana kwe-asbestos kunye nemilinganiselo yokuphendula ngokuzenzekelayo, olu cwaningo lusekela kwaye lugqithise obunye ubungqina obukhoyo ukuba, njenge-silika, i-asbestos yintsebenziswano yenkqubo yokuzimela," abalobi abafundayo babhala.
"I-vermiculite e-Asbestos ecocekileyo esuka eLibby iye yathunyelwa kwaye iqhutyelwa kwiindawo ezininzi e-United States, kwaye le nto isetyenziswa kwizicelo ezininzi. Ngako oko, ihlala ingumngcipheko wempilo ebantwini kubantu bobabini kunye nendawo yokusingqongileyo, kwaye ukuqonda ngokubambisana kunye nokuzimela komntu kungabangela impumelelo yokubeka iliso, ukuvavanya, kunye neyonyango kubantu abathile okanye abantu. "
Ngokusekelwe kwiziphumo zolu cwaningo oluncinane, abaphandi banenjongo yokuqhubela phambili izifundo zabo zezifo ezizimelayo phakathi kwabantu baseLibby.
I-Asbestos ibikude idibene neengcingo , i-fibrosis kunye nezinye izifo, kodwa unxibelelwano phakathi kwamanqaku angaphantsi kwesifo se-auto-immune kunye nokuchazwa kwe-asbestos kubalulekile ulwazi, "kusho uDkt. Jim Burkhart, umhleli wezesayensi ze-EHP.
Ababhali belifundo babe nguJean C. Pfau, uJami J. Sentissi, uGreg Weller, no-Elizabeth A. Putnam weZiko lezeMpilo zezeMvelo kwiYunivesithi yaseMontha.
