He aha nā PFA? Nā mea āpau e pono ai ʻoe e ʻike
E hahai i kā mākou blog ola nūhou Australia no nā mea hou loa
E kiʻi i kā mākou leka uila nūhou wā, polokalamu manuahi a i ʻole podcast nūhou i kēlā me kēia lā
Hiki iā ʻAukekulelia ke hoʻoikaika i nā lula e pili ana i nā pae i ʻae ʻia o nā kemika PFAS koʻikoʻi i ka wai inu, e hoʻohaʻahaʻa ana i ka nui o nā mea i kapa ʻia he mau kemika mau loa i ʻae ʻia no ka lita.
Ua hoʻokuʻu ka ʻAha Kūkākūkā Noiʻi Ola a me ke Lapaʻau Lapaʻau i ka Pōʻakahi i nā kulekele hoʻolālā e hoʻoponopono hou ana i nā palena no nā kemika PFAS ʻehā i ka wai inu.
ʻO ka PFAS (nā mea per- a me polyfluoroalkyl), he papa o kekahi mau tausani mau hui, i kekahi manawa i kapa ʻia ʻo "nā kemika mau loa" no ka mea e noho mau ana lākou i ke kaiapuni no ka manawa lōʻihi a ʻoi aku ka paʻakikī o ka luku ʻana ma mua o nā mea e like me ke kō a i ʻole nā protein. He ākea ka hōʻike ʻana o ka PFAS a ʻaʻole i kaupalena ʻia i ka wai inu.
E kākau inoa no ka leka uila nūhou wikiwiki a Guardian Australia
Hoʻonohonoho nā kulekele hoʻolālā i nā ʻōlelo aʻoaʻo no nā palena PFAS i ka wai inu i ke ola o ke kanaka.
Ma lalo o ke kānāwai, e hoʻohaʻahaʻa ʻia ka palena no PFOA - kahi hui i hoʻohana ʻia e hana iā Teflon - mai 560 ng/L a i 200 ng/L, ma muli o nā hōʻike o ko 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 PFOS - ʻo ia ka mea nui i ka mea pale lole Scotchgard - mai 70 ng/L a i 4 ng/L.
I Dekemaba o ka makahiki i hala, ua hoʻokaʻawale ka International Agency for Research on Cancer i ka PFOA ma ke ʻano he mea e hoʻoulu ai i ka maʻi kanesa i nā kānaka - ma ke ʻano like me ka inu ʻana i ka waiʻona a me ka haumia o ka ea o waho - a ʻo PFOS ma ke ʻano he "hiki" ke carcinogenic.
Hāʻawi pū nā alakaʻi i nā palena hou no ʻelua mau pūhui PFAS 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 ma ke ʻano he pani no PFOS ma Scotchgard mai ka makahiki 2023.
Ua ʻōlelo ke poʻo nui o ka NHMRC, ʻo Polopeka Steve Wesselingh, i loko o kahi hālāwai kūkā pāpāho ua hoʻokumu ʻia nā palena hou ma muli o nā hōʻike mai nā haʻawina holoholona. "ʻAʻole mākou e manaʻoʻiʻo i kēia manawa he mau haʻawina kanaka i lawa ka maikaʻi e alakaʻi iā mākou i ka hoʻomohala ʻana i kēia mau helu," wahi āna.
E kūlike ka palena PFOS i manaʻo ʻia me nā alakaʻi o ʻAmelika Hui Pū ʻIa, ʻoiai e ʻoi aku ke kiʻekiʻe o ka palena PFOA o ʻAukekulelia.
"ʻAʻole ia he mea maʻamau ka loli ʻana o nā waiwai alakaʻi mai kēlā ʻāina a kēia ʻāina a puni ka honua ma muli o nā ʻano hana like ʻole a me nā hopena i hoʻohana ʻia," wahi a Wesseleigh.
ʻO ka pahuhopu o ʻAmelika Hui Pū ʻIa no ka ʻole o ka nui o nā pūhui carcinogenic, ʻoiai ʻo nā mea hoʻoponopono o ʻAukekulelia e lawe i kahi ala "threshold model".
"Inā mākou e emi ma lalo o kēlā pae paepae, ke manaʻoʻiʻo nei mākou ʻaʻohe pilikia o kēlā mea ke kumu o ka pilikia i ʻike ʻia, inā paha he pilikia thyroid, pilikia iwi iwi a i ʻole ke kanesa," wahi a Wesseleigh.
Ua noʻonoʻo ka NHMRC e hoʻonohonoho i kahi palena wai inu PFAS i hui pū ʻia akā ua manaʻo ʻia he mea kūpono ʻole ia no ka nui o nā kemika PFAS. "Nui loa nā helu o PFAS, a ʻaʻohe o mākou ʻike ʻona no ka hapa nui o lākou," wahi a Kauka David Cunliffe, ke kākāʻōlelo koʻikoʻi no ka maikaʻi o ka wai no ka ʻoihana olakino SA. "Ua lawe mākou i kēia ala o ka hana ʻana i nā waiwai alakaʻi pākahi no kēlā mau PFAS kahi i loaʻa ai ka ʻikepili."
Ua kaʻana like ʻia ka hoʻokele ʻana o ka PFAS ma waena o ke aupuni pekelala a me ka mokuʻāina a me nā panalāʻau, nāna e hoʻoponopono i ka lako wai.
Ua ʻōlelo ʻo Kauka Daniel Deere, he loea wai a me ke olakino ma Water Futures, ʻaʻohe pono o ka poʻe Australia e hopohopo e pili ana i ka PFAS i loko o ka wai inu lehulehu ke ʻole e hoʻomaopopo pono ʻia. "He pōmaikaʻi mākou ma Australia no ka mea, ʻaʻohe o mākou wai i hoʻopilikia ʻia e ka PFAS, a pono ʻoe e hopohopo inā ua aʻo pololei ʻia e nā luna.
Inā ʻaʻole i ʻōlelo ʻia ma kahi ʻē aʻe, "ʻaʻohe waiwai o ka hoʻohana ʻana i nā kumu wai ʻē aʻe, e like me ka wai ʻōmole, nā ʻōnaehana mālama wai home, nā kānana wai benchtop, nā pahu wai ua kūloko a i ʻole nā lua," wahi a Deere i loko o kahi ʻōlelo.
"Hiki i nā poʻe ʻAukekulelia ke hoʻomau i ka hilinaʻi e hoʻokomo pū ana nā Alakaʻi Wai Inu ʻAukekulelia i ka ʻepekema hou loa a ikaika loa e kākoʻo i ka palekana o ka wai inu," wahi a Polofesa Stuart Khan, ke poʻo o ke Kula ʻenekinia Kīwila ma ke Kulanui o Sydney, ma kahi ʻōlelo.
Ua hoʻokumu ʻo NHMRC i kahi loiloi o nā alakaʻi o Australia no ka PFAS i ka wai inu i ka hopena o 2022. ʻAʻole i hōʻano hou ʻia nā alakaʻi mai ka makahiki 2018.
E waiho ʻia nā kulekele hoʻolālā no nā kūkākūkā a ka lehulehu a hiki i ka lā 22 o Nowemapa.
ʻO kaʻoiaʻiʻo, hiki iā mākou ke hoʻohana i nā mea ʻike wai e ʻike ai i ka maikaʻi o ka wai, hiki iā mākou ke hāʻawi i nā ʻano mea ʻike like ʻole e ana i nā ʻano like ʻole i ka wai no kāu kuhikuhi.
