Kei raro i te tirotiro ā-ao whānui te PFAS—e kiia ana ko ngā "matū pumau tonu". I te aukati a te EU i te PFAS i roto i ngā takai kai mai i te marama o Ākuhata 2026, me te whakakaha ake i ngā here o te US EPA PFAS Action Plan (2021–2024) puta noa i ngā ahumahi, kei raro i te pēhanga ngā kaihanga extrusion ki te whakakapi i ngā āwhina tukatuka polymer (PPA) e ahu mai ana i te fluoropolymer me ngā momo whakakapinga kore-PFAS.
He aha te take e tika ai kiawhakakorea te PFAS i roto i te extrusion polymer?
Ko ngā matū per- me polyfluoroalkyl (PFAS), he rōpū matū whakararuraru endocrine pumau, ā, e hono ana ki te mate pukupuku, te mate tairoi, me ngā take whānau uri. Kua whakamahia te PFAS i roto i ngā hua ahumahi me ngā hua kaihoko mai i te tekau tau atu i 1940. Kei ngā wāhi katoa te PFAS i roto i te taiao nā te mea he pumau te hanganga matū. Hei "matū pumau", kua kitea i roto i te oneone, te wai, me te hau.8 Hei tāpiri, kua kitea te PFAS i roto i ngā momo hua (hei tauira, ngā taputapu tunu kai korepiri, te papanga ātete-paru, ngā pahuka tinei ahi), te kai, me te wai inu, ā, e tata ana ki te katoa o te taupori whānui (>95%).
Nō reira, kua hua ake ngā ture pakari ake mō te whakamahinga o ngā tāpiringa whakarewa polymer i roto i te poke o te PFAS. Mō ngā kaihanga kiriata, paipa, me te taura, he mōrearea ngā PPA tuku iho mō te hanganga ture me te ingoa rongonui o te waitohu.
Kei raro nei ngā huringa ture me ngā kaupapa motuhake e whai wāhi ana ki tēnei whakawhiti, i runga i ngā mōhiohio e wātea ana:
1. Ngā Mahi Whakahaere a te Kotahitanga o Ūropi (EU):
• Te Herenga PFAS i Whakatakotoria e te ECHA (2023): I te Hui-tanguru 2023, i whakaarohia e te Tari Matū Pākehā (ECHA) he herenga whānui mō ngā matū per- me polyfluoroalkyl (PFAS) i raro i te ture REACH. E aro ana te tono ki te whānuitanga o ngā PFAS, tae atu ki ngā fluoropolymers e whakamahia ana hei āwhina tukatuka polymer (PPA). Ahakoa e rapu ana te umanga fluoropolymer i ngā whakawāteatanga, he mārama te aronga ture: ko ngā herenga kei te akiakihia e te pumau o te taiao me ngā mōrearea hauora pea o te PFAS. Ko te whāinga he whakawhāiti i tō rātou hanga, te whakamahinga, me te whakatakotoranga ki te mākete, ā, nā reira ka akiaki i ngā umanga ki te tango i ngā huarahi kē atu kāore he PFAS.
• Rautaki Matū a te EU mō te Oranga Tonu: He huarahi whānui te rautaki a te EU ki te whakahaere i ngā mōrearea PFAS, me te whakatairanga i te whakakorenga o ngā matū kino me te whakatairanga i te whanaketanga o ngā momo matū kore-hauora, tae atu ki ērā mō te tukatuka pūmua. Nā tēnei kua tere ake te auahatanga i roto i ngā PPA kore-PFAS, inā koa kia tutuki ai ngā ture e pā ana ki te kai me te takai.
• Te Ture Whakatakotoranga me te Para Takai a te Kotahitanga o Ūropi (PPWR) 2025: I whakaputaina ki te European Official Journal i te 22 o Hānuere, 2025, kei roto i te PPWR te aukati i te whakamahinga o te PFAS i roto i ngā takai kai e pā ana ki te kai mai i te 12 o Ākuhata, 2026. Ko te whāinga o te ture he whakaiti i te pānga taiao o ngā takai me te tiaki i te hauora o te marea mā te whakawhāiti i te PFAS i roto i ngā rauemi takai, tae atu ki ngā āwhina tukatuka polymer e whakamahia ana i roto i te whakaputanga kiriata kirihou. Hei tāpiri, e whakanui ana te PPWR i ngā whakaritenga hangarua—he wāhi e whakarato ana ngā PPA kore-PFAS i tētahi painga mārama—nā reira ka akiaki ake i te nekehanga ki ngā otinga takai pumau.
2. Ngā Whanaketanga Ture o te Hononga o Amerika
• Te Mahere Mahi PFAS a te EPA (2021–2024): Kua whakatinanahia e te Tari Tiaki Taiao o Amerika (EPA) ētahi mahi hei whakatika i te poke o te PFAS:
• Te Whakahuatanga o te PFOA me te PFOS hei Matū Morearea (Paenga-whāwhā 2024): I raro i te Ture Whakautu Taiao Whānui, Whakautu, me te Taunahatanga (Superfund), i tohua e te EPA te waikawa perfluorooctanoic (PFOA) me te waikawa perfluorooctanesulfonic (PFOS)—ngā matū matua o te PFAS e whakamahia ana i roto i ngā PPA—hei matū morearea. Ka whakanui ake tēnei i te māramatanga me te kawenga mō te horoi, ā, ka akiaki i ngā ahumahi ki te neke ki ngā huarahi kē atu ehara i te PFAS.
• Paerewa Wai Inu ā-Motu (Paenga-whāwhā 2024): I whakaotihia e te EPA te paerewa wai inu tuatahi e whai mana ana mō te PFAS, me te whāinga kia whakaitihia te pānga ki te tata ki te 100 miriona tāngata. Ka akiakihia ā-tikangatia e tēnei ture ngā ahumahi ki te whakakore i te PFAS mai i ngā tukanga hanga, tae atu ki ngā PPA, hei ārai i te poke o ngā puna wai.
• Ngā Tāpiritanga o te Rārangi Tukunga Paitini (TRI) (Hanuere 2024): I tāpirihia e te EPA e whitu ngā PFAS ki te TRI i raro i te Ture Whakamanatanga Tiaki ā-Motu o te tau 2020, e hiahiatia ana kia ripoatahia mō te tau 2024. Ka whakapiki ake tēnei i te tirotiro i ngā PPA kei roto ko te PFAS, ā, ka akiaki i te tango i ngā huarahi kē atu kāore he PFAS.
• Ngā Whakaaro mō te Ture Tiaki me te Whakaora Rauemi (RCRA) (Hui-tanguru 2024): I whakaarohia e te EPA ngā ture hei tāpiri i te iwa PFAS ki te rārangi o ngā wāhanga morearea i raro i te RCRA, hei whakarei ake i te mana horoi me te akiaki anō i ngā kaihanga ki ngā otinga kore-PFAS.
• Ngā Ārai Taumata-Kāwanatanga: Kua whakatinanahia e ngā kāwanatanga pērā i a Minnesota ngā ārai mō ngā hua kei roto he PFAS, pērā i ngā taputapu tunu kai, e tohu ana i te whānui ake o te aukati i ngā rauemi kei roto he PFAS, tae atu ki ngā PPA e whakamahia ana i roto i ngā tono kai-pā. Ko ētahi atu kāwanatanga, tae atu ki a California, Michigan, me Ohio, kua kī ko te korenga o ngā mahi a te kāwanatanga te take mō ngā ture PFAS taumata-kāwanatanga, e akiaki ana i te nekehanga ki ngā PPA kore-PFAS.
3. Ngā Kaupapa ā-Ao me ngā Kaupapa ā-Rohe:
• Anga Whakahaere o Kanata: Kua whakatūria e Kanata ngā ture kaha hei whakaiti me te whakahaere i te hanga me te whakamahinga o te PFAS, e awe ana i ngā kaihanga o te ao ki te whakakapi i ngā PPA e hangai ana ki te PFAS ki ngā momo whakakapinga kore-hauora.
• Huihuinga o Stockholm: Kua neke atu i te tekau tau te roa o te kōrero ā-ao mō te ture PFAS, inā koa mō te waikawa perfluorooctanesulfonic (PFOS) me ngā matū e pā ana. Ahakoa kāore ngā whenua katoa (hei tauira, ko Brazil me Haina) e aukati katoa ana i ētahi PFAS, ko te ia o te ao ki te ture e tautoko ana i te tango i ngā PPA kore-PFAS.
• Te Whakapumautanga Whakamutu a 3M (2022): I panuitia e 3M, he kaihanga PFAS nui, ka mutu tana hanga PFAS i te mutunga o te tau 2025, ka piki ake te tono mō ngā PPA kore-PFAS hei whakakapi i ngā āwhina e ahu mai ana i te fluoropolymer i roto i ngā ahumahi pēnei i te kiriata me te whakaputanga paipa
4. Ngā Ture Whakatutuki i ngā Pānga Kai:
Ko ngā ture a te US Food and Drug Administration (FDA) me te European Food Safety Authority (EFSA) e whakanui ana i ngā PPA kore-PFAS mō ngā tono e pā ana ki te kai.
5. Te Pēhanga o te Mākete me te Ahumahi
Haunga ngā ture whakahaere, ko te hiahia o ngā kaihoko mō ngā hua e pai ana ki te taiao me ngā whāinga pumau a ngā kamupene kei te akiaki i ngā kaipupuri waitohu me ngā kaihanga ki te whakamahi i ngā PPA kore-PFAS. He tino kitea tēnei i roto i te umanga takai, e rapuhia ana ngā otinga kore-PFAS mō ngā takai ngāwari, ngā kiriata pupuhi, me ngā kiriata whakarewa hei whakatutuki i ngā tumanakohanga o te mākete me te karo i te kino o te ingoa pai.
Urupare Ahumahi: Ngā PPA Kore-PFAS
Kua whakautu mai ngā kaiwhakarato tāpiringa polymer nui pērā i a Silike, Clariant, Baerlocher, Ampacet, me Tosaf mā te whakawhanake i ngā PPA kore-PFAS e rite ana, e hipa ana rānei i te mahi a ngā āwhina e hangai ana ki te fluoropolymer. Ka āwhina ēnei huarahi kē ki te whakaiti i te pakaru rewa, te hanga mate, me te pēhanga extrusion, me te whakarite kia tutukihia ngā ture pa-kai me te tautoko i ngā whāinga pumau.
Hei tauira,Ko ngā Tāpiri Whakaputa Poramu Raupapa Silike SILIMER e tuku ana i te kore-PFAS, ngā otinga kore-hauorahei wikitoria i ngā wero tukatuka. I hangaia mō ngā kiriata pupuhi, whakarewa, me ngā kiriata paparanga maha, muka, taura, paipa, masterbatch, compounding, me te maha atu, ka taea e ia te whakarei ake i te mahi tukatuka o te whānuitanga o ngā polyolefins, tae atu ki engari kāore i te herea ki te mLLDPE, LLDPE, LDPE, HDPE, PP, me ngā polyolefins hangarua.
