Uphononongo luqinisekisile ukuba imibhobho yethu yesamente egugayo iguguleka ngokukhawuleza kunaphesheya kweelwandle, kwaye imicu ye-asbestos ingena emanzini - kodwa ingekabikho kumanqanaba ayingozi okwangoku.
Abaphandi abavela kwiYunivesithi yase-Otago yeSikole seJografi bafumene "ubungqina obuninzi" beentsinga ze-asbestos kwiisampulu zamanzi okusela ezivela kwiindawo ezingama-35 ezijikeleze iChristchurch kwaye bathi oku kuya kuphinda kuphindwe kunikezelo lwamanzi kwilizwe liphela.
Ngoku iNew Zealand ine-9000km yemibhobho ye-asbestos ekufuneka itshintshwe ngexabiso eliqikelelwa kwi-2.2 yeebhiliyoni zeedola, olu phando lwathi.
Isamente ye-asbestos yayisetyenziswa kwimibhobho yamanzi kwihlabathi jikelele ukusuka kwiminyaka yoo-1930 ukuya koo-1980, xa kwakubonakala ukuba inokukhulula imicu ye-asbestos kunikezelo lwamanzi xa yonakele.

Ababhali bophononongo bathi uninzi lwemibhobho ngoku sele idlulile ubomi babo obuluncedo kwaye isengozini yokungaphumeleli.
Umbhali-mbhali uGqr Sarah Mager uthe kwiindawo ezininzi zaseNew Zealand, unikezelo lwamanzi lunamanqanaba asezantsi e-calcium kunye ne-magnesium, evumela imibhobho ye-asbestos yesamente ukuba ihlehlise ngesantya esiphezulu kwaye ikhuphe iifayibha ze-asbestos ezininzi.
"Isantya sokubola sikhawuleza kakhulu, ngoko ke imibhobho ibola ngaphakathi ngokukhawuleza kunemizekelo yangaphandle."
Kuphononongo lwe-Christchurch, iifayibha ze-asbestos zifunyenwe kwiisampuli ze-19 zeendawo ze-20 ze-fire hydrant kunye ne-3 ye-16 yeesampuli zempompo zekhaya.
Loo mali ayizange idlule amanqanaba akhuselekileyo phantsi kwezikhokelo zase-US-ekuphela kwelizwe elinezikhokelo ze-asbestos emanzini okusela.
Ilabhoratri yeengcali zamazwe ngamazwe e-US ihlalutye iisampulu zamanzi ezivela e-Christchurch kwinto abaphandi bathi sisihlandlo sokuqala ukuba ihlole ngokuchanekileyo ukhukuliseko lonikezelo lwamanzi oluvela kwimibhobho ye-asbestos yaseNew Zealand.
IBhunga lesiXeko sase-Christchurch lalikhe lathatha isampuli ze-17 ze-hydrants ze-asbestos fibers kwi-2017 kwaye zazifumana kwenye.
Nangona iingozi ze-asbestos emoyeni njenge-carcinogen ziyaziwa kakuhle, imiphumo yempilo yokuyingenisa ayizange igqitywe kwaye akukho mqobo wokulawula ukukhawulela imicu ye-asbestos emanzini okusela eNew Zealand.
Ingxelo, epapashwe yi-International Water Association's Journal of Water Supply, ikhankanya izifundo zamva nje ezibonisa ukuhambelana phakathi kwe-asbestos etyiweyo kunye nokuxhaphaka kwe-gastric and colorectal cancers, kunye nobukho be-asbestos kwizicubu zesisu. ubungqina kwi.
Umbutho wezeMpilo weHlabathi, izikhokelo zokulawula umgangatho wamanzi okusela waseNew Zealand kunye nezikhokelo zamanzi okusela zase-Australia zichaza ukuba akukho datha eyaneleyo kwihlabathi jikelele ukutsala ikhonkco lezempilo kwi-asbestos emanzini okusela.
Sekunjalo, ababhali abasebenzisanayo bolu phando bathi imiphumo ye-asbestos kumanzi okusela ayizange ifundwe ngokwaneleyo.
"Unxibelelwano lwe-epidemiological phakathi kwe-asbestos fibers kumanzi okusela kunye nesiganeko somhlaza sinokumiselwa kuphela ukuba idatha ye-asbestos fibers ikhona: ezi datha aziqokelelwa rhoqo."
Imibhobho yesamente yeasbestos yaziwa ngokuba buthathaka kwiinyikima kuba iethe-ethe kwaye yonakala lula.
Uphononongo lufumene ugxininiso oluphezulu lweentsinga ze-asbestos zafunyanwa kumadlelo asempuma esixeko, apho imibhobho yafakwa ngokugalelwa komhlaba wemveli endaweni yegrabile.Ummandla wafumana ukunyibilika okunzulu komhlaba ngexesha lenyikima yaseCanterbury ka-2011.
U-Tim Drennan, obambele intloko yamanzi amathathu kwiBhunga lesiXeko sase-Christchurch, uthe kukho ukonyuka “kweenkqubo eziqhubekayo zohlaziyo” ukusukela ngeminyaka yoo-1990 kwaye isixeko sasinepesenti ezingama-21 kuphela zonikezelo lwamanzi lwaso.
"Kubalulekile ukuphinda kwakhona ukuba imibhobho ye-asbestos yesamente kuthungelwano lwethu lwamanzi ayibangeli naziphi na iingxaki zempilo ngokukhawuleza."
UDrennan uthe ibhunga liqhuba “inkqubo yokubeka phambili umngcipheko esekwe kumngcipheko” eqwalasela indlela ukungaphumeleli okuchaphazela ngayo uluntu luphela.
UDrennan uthe uninzi lohlaziyo lwemibhobho yamanzi ibhunga elicwangciselwe kule minyaka ingama-27 izayo iza kuba yimibhobho yesamente yeasbestos.
Ngenxa yesampulu elinganiselweyo, ababhali abakwazanga ukufumanisa ukuba umonakalo wenyikima kunye nokuchithwa kwe-liquefaction e-Christchurch kuthetha ukuba unikezelo lwamanzi esixekweni lunamanqanaba aphezulu e-asbestos fibers kunezinye iindawo.
Nangona kunjalo, bacebisa ukuba onke amabhunga “abeke iliso kunikezelo lwamanzi oluxeliweyo kwiintsinga ze-asbestos, ngakumbi njengoko le mibhobho ifikelela ekupheleni kobomi bayo obuluncedo, ukubona ukuguga kwemibhobho kwaye ibeke phambili ukutshintshwa kwamacandelo emibhobho”.
"Le yingxaki yesizwe kuba imibhobho ye-samente-asbestos ineminyaka efanayo kwaye ifakwe - ngoko kunengqiqo ukucinga ukuba yonke iNew Zealand iya kuba nesantya esifanayo sokukhululwa kwe-asbestos," kusho umbhali-mbhali uMichael Nopic.
“Inyani yeyokuba iphantsi komhlaba, ifihliwe, kwaye asicingi ngayo de ingasebenzi.”
