Ka taea e Ahitereiria te whakakaha ake i ngā ture e pā ana ki ngā taumata e whakaaetia ana o ngā matū PFAS matua i roto i te wai inu, me te whakaiti i te nui o ngā matū e kiia nei ko ngā matū pumau e whakaaetia ana mō ia rita.
I tukuna e te Kaunihera Rangahau Hauora me te Hauora ā-Motu i te Rāhina ngā aratohu tauira e whakahou ana i ngā here mō ngā matū PFAS e whā i roto i te wai inu.
Ko te PFAS (ngā matū ia- me te polyfluoroalkyl), he akomanga o ngā mano tini matū, e kiia ana i ētahi wā ko ngā "matū pumau" nā te mea ka roa te noho ki te taiao, ā, he uaua ake te whakangaro i ngā matū pēnei i te huka, i te pūmua rānei. He whānui te pānga o te PFAS, ā, kāore i te herea ki te wai inu anake.

Kei roto i ngā aratohu tauira ngā taunakitanga mō ngā herenga PFAS i roto i te wai inu mō te roanga o te oranga o te tangata.
I raro i te tauira, ka whakaitihia te rohenga mō te PFOA – he matū e whakamahia ana hei hanga Teflon – mai i te 560 ng/L ki te 200 ng/L, i runga i ngā taunakitanga o ōna pānga mate pukupuku.
I runga i ngā āwangawanga hou mō ngā pānga o te hinu wheua, ka tapahia ngā here mō te PFOS – te matū matua i mua i roto i te pare kakahu Scotchgard – mai i te 70 ng/L ki te 4 ng/L.
I te marama o Tīhema o te tau kua hipa, i whakarōpūtia e te International Agency for Research on Cancer te PFOA hei mate pukupuku e pāngia ai te tangata – i roto i te kāwai kotahi me te inu waipiro me te parahanga o waho – ā, ko te PFOS he "pea" he mate pukupuku.
Kei roto hoki i ngā aratohu he herenga hou mō ngā matū PFAS e rua i runga i ngā taunakitanga o ngā pānga o te tairoi, arā, 30ng/L mō te PFHxS me te 1000 ng/L mō te PFBS. Kua whakamahia te PFBS hei whakakapi mō te PFOS i Scotchgard mai i te tau 2023.
I roto i tētahi huihuinga pāpāho, i kī te tumuaki o te NHMRC, a Ahorangi Steve Wesselingh, i whakatakotoria ngā here hou i runga i ngā taunakitanga mai i ngā rangahau kararehe. "Kāore mātou i te whakapono i tēnei wā he rangahau tangata kei te kounga rawaka hei ārahi i a mātou ki te whakawhanake i ēnei tatauranga," tana kī.
Ka rite te herenga PFOS kua whakaarohia ki ngā aratohu a te US, engari ka teitei ake tonu te herenga PFOA a Ahitereiria.
"Ehara i te mea onge te rerekētanga o ngā uara aratohu i ia whenua ki ia whenua huri noa i te ao i runga i ngā tikanga me ngā mutunga rerekē e whakamahia ana," te kī a Wesseleigh.
Ko te whāinga a te US kia kore rawa he kukū o ngā matū whakaputa mate pukupuku, ko ngā kaiwhakahaere o Ahitereiria ia e whai ana i te huarahi "tauira paepae".
"Ki te heke iho tātou i taua taumata paepae, e whakapono ana mātou kāore he mōrearea kei puta te raruraru kua tautuhia mai i taua matū, ahakoa he raruraru tairoi, he raruraru hinu wheua, he mate pukupuku rānei," te kī a Wesseleigh.
I whakaarohia e te NHMRC te whakatakoto i tētahi rohenga wai inu PFAS whakakotahi, engari i kitea he mea koretake tēnei i runga i te maha o ngā matū PFAS. "He tino nui ngā PFAS, ā, kāore ā mātou mōhiohio paitini mō te nuinga o rātou," te kī a Tākuta David Cunliffe, te kaitohutohu kounga wai matua mō te tari hauora o Awherika ki te Tonga. "Kua tangohia e mātou tēnei ara o te whakaputa i ngā uara aratohu takitahi mō aua PFAS kei reira ngā raraunga e wātea ana."
Ko te whakahaere o te PFAS he mea tiritiri i waenga i te kāwanatanga ā-motu me te kāwanatanga ā-rohe, ā, ko rātou anō te kaiwhakahaere o te tuku wai.
I kī a Tākuta Daniel Deere, he kaitohutohu wai me te hauora i Water Futures, kāore he take e manukanuka ai ngā tāngata o Ahitereiria mō te PFAS i roto i te wai inu tūmatanui mēnā kāore i te whakamōhiotia. "He waimarie tātou i Ahitereiria nā te mea he iti noa iho te wai e pāngia ana e te PFAS, ā, me manukanuka noa koe mēnā ka tohutohu tika mai ngā mana whakahaere."
"Ki te kore e tohua tētahi atu kupu, kāore he hua o te whakamahi i ngā puna wai rerekē, pērā i te wai pounamu, ngā pūnaha maimoatanga wai o te whare, ngā tātari wai papa, ngā tāke wai ua o te rohe, ngā poka wai rānei," te kī a Deere i roto i tētahi kōrero.
"Ka taea tonu e ngā tāngata o Ahitereiria te whakapono kei roto i ngā Aratohu Wai Inu o Ahitereiria ngā pūtaiao hou me te tino pakari hei tautoko i te haumaru o te wai inu," te kī a Ahorangi Stuart Khan, te tumuaki o te Kura Hangarau Ā-iwi i Te Whare Wānanga o Poihākena, i roto i tētahi kōrero.
I te mutunga o te tau 2022, i arotakehia e te NHMRC ngā aratohu a Ahitereiria mō te PFAS i roto i te wai inu. Kāore anō kia whakahoutia ngā aratohu mai i te tau 2018.
Ka waiho ngā aratohu tauira hei whakawhitiwhiti kōrero mā te marea tae noa ki te 22 o Noema.
Ina hoki, ka taea e tātou te whakamahi i ngā pūoko kounga wai hei kite i te kounga o te wai, ka taea e tātou te whakarato i ngā momo pūoko hei ine i ngā tawhā rerekē i roto i te wai hei tohutoro māu.
