Australiya irashobora gukaza amategeko yerekeye urwego rwemewe rw'imiti y'ingenzi ya PFAS mu mazi yo kunywa, bikagabanya urugero rwitwa imiti iteka yemerewe kuri litiro.

Ku wa mbere, Inama y’igihugu y’ubuzima n’ubuvuzi yashyize ahagaragara umushinga w’amabwiriza avugurura imipaka y’imiti ine ya PFAS mu mazi yo kunywa.

PFAS (per- na polyfluoroalkyl), icyiciro cyibintu ibihumbi byinshi, rimwe na rimwe byitwa "imiti iteka ryose" kuko bikomeza ibidukikije igihe kirekire kandi bigoye kurimbura kuruta ibintu nka sukari cyangwa proteyine. PFAS igaragara ni nini kandi ntabwo igarukira kumazi yo kunywa.

Umushinga ngenderwaho werekanye ibyifuzo byurugero rwa PFAS mumazi yo kunywa mubuzima bwumuntu.

Mu mushinga, imipaka ya PFOA - uruganda rukoreshwa mu gukora Teflon - rwamanurwa ruva kuri 560 ng / L rugera kuri 200 ng / L, rushingiye ku bimenyetso byerekana ingaruka zabo zitera kanseri.

Ukurikije impungenge nshya zijyanye n'ingaruka z'amagufwa, imipaka ya PFOS - mbere yingenzi mu bintu birinda imyenda Scotchgard - yagabanywa kuva 70 ng / L ikagera kuri 4 ng / L.

Mu Kuboza umwaka ushize, Ikigo mpuzamahanga gishinzwe ubushakashatsi kuri kanseri cyashyize PFOA nk'abantu batera kanseri - mu cyiciro kimwe no kunywa inzoga no guhumanya ikirere cyo hanze - na PFOS nka kanseri ishobora kuba.

Amabwiriza atanga kandi imipaka mishya kubintu bibiri bya PFAS bishingiye ku bimenyetso byerekana ingaruka za tiroyide, ya 30ng / L kuri PFHxS na 1000 ng / L kuri PFBS. PFBS yakoreshejwe nk'umusimbura wa PFOS muri Scotchgard kuva 2023.

Umuyobozi mukuru wa NHMRC, Prof Steve Wesselingh, mu kiganiro n'abanyamakuru yavuze ko imipaka mishya yashyizweho hashingiwe ku bimenyetso bivuye mu bushakashatsi bw’inyamaswa. Ati: "Kugeza ubu ntitwemera ko hari ubushakashatsi bw’abantu bufite ireme buhagije bwo kutuyobora mu guteza imbere iyo mibare".

Umupaka wa PFOS uteganijwe uzaba uhuye nubuyobozi bwa Amerika, mugihe Australiya ntarengwa ya PFOA yaba ikiri hejuru.

Wesseleigh yagize ati: "Ntibisanzwe ko indangagaciro ngenderwaho zitandukanye bitewe n'ibihugu bitandukanye ku isi hashingiwe ku buryo butandukanye ndetse n'impera zikoreshwa."

Amerika igamije kwibanda kuri zeru yibintu bya kanseri, mugihe abagenzuzi ba Australiya bafata inzira "yerekana urugero".

Wesseleigh yagize ati: "Niba tugeze munsi y'urwo rwego, twizera ko nta kaga ko kuba ibintu bitera ikibazo cyagaragaye, cyaba ibibazo bya tiroyide, ibibazo by'amagufwa cyangwa kanseri."

NHMRC yatekereje gushyiraho urugero rw’amazi yo kunywa ya PFAS ariko isanga bidakwiye ukurikije umubare w’imiti ya PFAS. Dr David Cunliffe, umujyanama mukuru w’amazi meza mu ishami ry’ubuzima SA, yagize ati: "Hariho umubare munini cyane wa PFAS, kandi nta makuru y’uburozi dufite kuri benshi muri bo." Ati: "Twafashe iyi nzira yo gutanga indangagaciro ngenderwaho kuri izo PFAS ahari amakuru ahari."

Ubuyobozi bwa PFAS busangiwe hagati ya guverinoma n’ubutegetsi bwa leta n’intara, bigenga itangwa ry’amazi.

Dr Daniel Deere, umujyanama w’amazi n’ubuzima muri Water Futures, yavuze ko Abanyaustraliya badakeneye guhangayikishwa na PFAS mu mazi yo kunywa rusange keretse babimenyeshejwe. Ati: "Dufite amahirwe muri Ositaraliya kubera ko nta mazi dufite yatewe na PFAS, kandi ugomba guhangayikishwa gusa n’ubuyobozi butanzwe n’ubuyobozi.

Keretse iyo bigiriwe inama ukundi, "nta gaciro byari bifite mu gukoresha ubundi buryo bw'amazi, nk'amazi icupa, uburyo bwo gutunganya amazi yo mu rugo, akayunguruzo k'amazi yo ku ntebe, ibigega by'amazi y'imvura cyangwa bore", Deere yagize ati.

Mu ijambo rye, Prof Stuart Khan, umuyobozi w’ishuri ry’ubwubatsi muri kaminuza ya Sydney, yagize ati: "Abanyaustraliya barashobora gukomeza kumva bafite icyizere ko Amabwiriza y’amazi yo muri Ositaraliya akubiyemo ubumenyi bugezweho kandi bukomeye mu gushimangira umutekano w’amazi yo kunywa."

NHMRC yashyize imbere gusuzuma amabwiriza ya Ositaraliya kuri PFAS mu mazi yo kunywa mu mpera za 2022.Amabwiriza ntabwo yari yaravuguruwe kuva 2018.

Umushinga w'amabwiriza uzakomeza kugirwa inama rusange kugeza 22 Ugushyingo.

Mubyukuri, turashobora gukoresha ibyuma byamazi meza kugirango tumenye ubwiza bwamazi, turashobora gutanga ibyuma bitandukanye kugirango dupime ibipimo bitandukanye mumazi kugirango ubone
