E hahai i kā mākou Australia news live blog no nā mea hou loa
E kiʻi i kā mākou leka uila nūhou, ka app manuahi a i ʻole podcast nūhou i kēlā me kēia lā
Hiki i Australia ke hoʻoikaika i nā lula e pili ana i nā pae ʻae ʻia o nā kemika PFAS koʻikoʻi i ka wai inu, e hoʻohaʻahaʻa ana i ka nui o nā mea i kapa ʻia ʻo kemika mau loa i ʻae ʻia i kēlā me kēia lita.
Ua hoʻokuʻu ka National Health and Medical Research Council i ka Pōʻakahi i nā alakaʻi alakaʻi e hoʻoponopono hou ana i nā palena no nā kemika PFAS ʻehā i ka wai inu.
ʻO ka PFAS (per- a me polyfluoroalkyl substances), he papa o nā kaukani pūhui, i kekahi manawa i kapa ʻia ʻo "kemika mau loa" i ko lākou hoʻomau ʻana i ke kaiapuni no nā manawa lōʻihi a ʻoi aku ka paʻakikī o ka luku ʻana ma mua o nā mea e like me ke kō a me nā protein. He ākea ka hōʻike PFAS a ʻaʻole i kaupalena ʻia i ka wai inu.
E kākau inoa no ka leka uila nūhou a Guardian Australia
Hoʻonohonoho nā kumu alakaʻi i nā ʻōlelo aʻoaʻo no nā palena PFAS i ka wai inu i ke ola o ke kanaka.
Ma lalo o ke kiʻi, e hoʻohaʻahaʻa ʻia ka palena no ka PFOA - kahi mea i hoʻohana ʻia e hana ai i Teflon - mai 560 ng / L a i 200 ng / L, e pili ana i nā hōʻike o kā lākou hopena maʻi kanesa.
Ma muli o nā hopohopo hou e pili ana i nā hopena o ka iwi iwi, e ʻoki ʻia nā palena no ka PFOS - ma mua ka mea nui o ka pale lole Scotchgard - mai 70 ng / L a i 4 ng / L.
I Kekemapa i ka makahiki i hala, ua hoʻokaʻawale ka International Agency for Research on Cancer i ka PFOA ma ke ʻano he maʻi maʻi maʻi i ke kanaka - ma ke ʻano like me ka inu ʻana i ka waiʻona a me ka pollution o waho - a ʻo PFOS ma ke ʻano he carcinogenic.
Hoʻopuka pū nā alakaʻi i nā palena hou no nā pūhui PFAS ʻelua e pili ana i nā hōʻike o nā hopena thyroid, ʻo 30ng/L no PFHxS a me 1000 ng/L no PFBS. Ua hoʻohana ʻia ʻo PFBS i mea pani no PFOS ma Scotchgard mai 2023.
ʻO ka luna nui o ka NHMRC, ʻo Prof Steve Wesselingh, i ʻōlelo ʻia i loko o kahi puʻupuʻu media ua kau ʻia nā palena hou ma muli o nā hōʻike mai nā haʻawina holoholona. "ʻAʻole mākou i manaʻoʻiʻo i kēia manawa aia nā haʻawina kanaka i lawa ka maikaʻi e alakaʻi iā mākou i ka hoʻomohala ʻana i kēia mau helu," wahi āna.
ʻO ka palena PFOS i manaʻo ʻia e pili pū me nā alakaʻi US, ʻoiai ʻoi aku ka kiʻekiʻe o ka palena Australia o PFOA.
"ʻAʻole ia he mea maʻamau ka ʻokoʻa ʻana o nā waiwai alakaʻi mai kēlā me kēia ʻāina a puni ka honua e pili ana i nā ʻano hana like ʻole a me nā hopena i hoʻohana ʻia," wahi a Wesseleigh.
Ke manaʻo nei ʻo ʻAmelika i ka helu ʻole o nā pūhui carcinogenic, aʻo nā mea hoʻoponopono o Australia e lawe i kahi "hoʻohālike paepae".
"Inā loaʻa mākou ma lalo o kēlā pae paepae, manaʻo mākou ʻaʻohe pilikia o kēlā mea ke kumu i ʻike ʻia ai ka pilikia, inā he pilikia thyroid, pilikia o ka iwi iwi a i ʻole ka maʻi kanesa," wahi a Wesseleigh.
Ua noʻonoʻo ka NHMRC i ka hoʻonohonoho ʻana i kahi palena wai inu PFAS i hui pū ʻia akā manaʻo ʻia he mea hiki ʻole ke hāʻawi ʻia i nā helu o nā kemika PFAS. "He nui ka nui o ka PFAS, a ʻaʻohe o mākou ʻike toxicological no ka hapa nui o lākou," wahi a Dr David Cunliffe, ka ʻōlelo aʻoaʻo kumu wai no ke keʻena olakino SA. "Ua lawe mākou i kēia ala o ka hana ʻana i nā waiwai alakaʻi no kēlā PFAS kahi i loaʻa ai ka ʻikepili."
Hoʻokaʻawale ʻia ka hoʻokele PFAS ma waena o ke aupuni federal a me ka mokuʻāina a me nā panalāʻau, nāna e hoʻoponopono i ka lako wai.
Ua ʻōlelo ʻo Dr Daniel Deere, kahi mea aʻoaʻo wai a me ke olakino ma Water Futures, ʻaʻole pono ka poʻe Australia e hopohopo e pili ana i ka PFAS i ka wai inu lehulehu ke ʻole i hōʻike ʻia. "Pōmaikaʻi mākou ma Australia no ka loaʻa ʻole o ka wai i hoʻopilikia ʻia e PFAS, a pono ʻoe e hopohopo inā ʻōlelo pololei ʻia e nā luna.
Inā ʻaʻole i ʻōlelo ʻia, "ʻaʻohe waiwai o ka hoʻohana ʻana i nā kumu wai ʻē aʻe, e like me ka wai huehue, nā ʻōnaehana mālama wai hale, nā kānana wai benchtop, nā pahu wai ua a i ʻole nā bores," i ʻōlelo ai ʻo Deere ma kahi ʻōlelo.
"Hiki i ka poʻe Australia ke hoʻomau i ka hilinaʻi i ka Australian Drinking Water Guidelines e hoʻokomo i ka ʻepekema hou loa a ikaika loa e kākoʻo i ka palekana wai inu," i ʻōlelo ai ʻo Prof Stuart Khan, ke poʻo o ke Kula ʻo Civil Engineering ma ke Kulanui o Sydney, i loko o kahi ʻōlelo.
Ua hoʻonohonoho mua ʻo NHMRC i kahi loiloi o nā alakaʻi Australian ma PFAS i ka wai inu i ka hopena o 2022. ʻAʻole i hoʻonui ʻia nā alakaʻi mai 2018.
E waiho ʻia nā kumu kuhikuhi no ke kūkākūkā lehulehu a hiki i ka lā 22 Nowemapa.
ʻO kaʻoiaʻiʻo, hiki iā mākou ke hoʻohana i nā meaʻike wai no kaʻikeʻana i ka maikaʻi o ka wai, hiki iā mākou ke hāʻawi i nāʻano likeʻole e ana i nāʻano likeʻole i ka wai no kāu kuhikuhi.
