Chifukwa chiyani zochulukira zochulukira zamtundu wa nzimbe zimapangidwira PFAS zaulere?

Pomwe nkhawa zakula paziwopsezo zomwe zingachitike paumoyo komanso zachilengedwe zomwe zimakhudzana ndi perfluoroalkyl ndi polyfluoroalkyl substances (PFAS), pakhala kusintha kwa zodula nzimbe zopanda PFAS. Nkhaniyi ikufotokoza zomwe zidapangitsa kusinthaku, kuwunikira thanzi ndi chilengedwe cha PFAS komanso maubwino ogwiritsira ntchito zida zapa tebulo zopanda PFAS zopangidwa ndi zamkati zanzimbe.

Kuopsa kwa PFAS Perfluoroalkyl ndi zinthu za polyfluoroalkyl, zomwe zimatchedwa PFAS, ndi gulu la mankhwala opangidwa ndi mafakitale ndi ogula kuti asatenthe, madzi, ndi mafuta.

Tsoka ilo, zinthuzi siziwonongeka mosavuta ndipo zimakonda kudziunjikira m'chilengedwe komanso m'thupi la munthu. Kafukufuku wambiri awonetsa kuti kukhudzana ndi PFAS kumatha kukhala ndi zotsatirapo zoyipa zaumoyo, kuphatikiza khansa ya impso ndi testicular, kuwonongeka kwa chiwindi, kuchepa kwa chonde, zovuta zakukula kwa makanda ndi ana, komanso kusokoneza kuchuluka kwa mahomoni.

Mankhwalawa apezekanso kuti akupitilirabe ku chilengedwe kwa zaka makumi ambiri, akuwononga madzi ndi nthaka komanso kuopseza zachilengedwe.nzimbe Pulp TablewarePozindikira zowopsa za PFAS, ogula ndi mafakitale akufunafuna njira zina zotetezeka. Zipatso za nzimbe, zomwe zidapangidwa popanga shuga, zakhala njira yothandiza komanso yosamalira zachilengedwe kusiyana ndi zida zapakale zopangidwa ndi zinthu monga pulasitiki kapena Styrofoam.

Zakudya zamtundu wa nzimbe zimapangidwa kuchokera ku bagasse, zotsalira za ulusi zomwe zimatsalira pambuyo potulutsa madzi a nzimbe. Ndi biodegradable, kompositi ndipo safuna zida namwali kuti apange. Kuwonjezera apo, nzimbe zingabzalidwe mofulumira, zomwe zimapangitsa kuti pakhale gwero lokhazikika komanso lotha kusintha.

Ubwino wokhala wopanda PFAS Chimodzi mwazifukwa zazikulu zakuchulukirachulukira kwa zodula nzimbe zopanda PFAS ndikupewa ngozi zomwe zingachitike paumoyo. Opanga akusiya kugwiritsa ntchito PFAS pakupanga kwawo kuti awonetsetse kuti malonda awo ndi otetezeka komanso opanda mankhwala owopsa. Ogwiritsa ntchito akudziwa kufunikira kochepetsera kukhudzidwa kwawo ndi PFAS ndipo akufunafuna njira zina zopanda PFAS.

Kufuna kumeneku kwapangitsa opanga kuunikiranso machitidwe awo ndikuyika ndalama muukadaulo wopanda PFAS, zomwe zapangitsa kuti pakhale kupezeka kwa njira zotetezeka zapa tableware izi.ubwino wa chilengedwe Kuphatikiza pa mapindu azaumoyo,PFAS-yopandanzimbe zamkati mbalezilinso ndi ubwino wambiri pa chilengedwe. Zida zamapulasitiki zimakhala ndi vuto lalikulu loyang'anira zinyalala chifukwa zimatenga zaka mazana ambiri kuti ziwole ndipo nthawi zambiri zimatha kutayira, m'nyanja kapena m'malo otenthetsera.

Mosiyana ndi zimenezi, kudula nzimbe ndi kotheratubiodegradable ndi kompositi. Zimathandizira kuchepetsa kupanikizika kwa machitidwe oyendetsa zinyalala omwe asokonezeka kale ndipo zimathandiza kuti chuma chikhale chokhazikika komanso chozungulira.

Pogwiritsa ntchito njira zopanda PFASzi, ogula amatha kukhudza chilengedwe ndikupita ku tsogolo lobiriwira, lodalirika.Kuwongolera ndi zochita zamakampani Pozindikira kuopsa kwa PFAS, olamulira m'mayiko ena akuyesetsa kuchepetsa kugwiritsa ntchito mankhwala owopsawa.

Mwachitsanzo, ku United States, bungwe la Environmental Protection Agency (EPA) lakhazikitsa upangiri waumoyo kwa PFAS ina m'madzi akumwa, ndipo mayiko pawokha akukhazikitsa malamulo oletsa kapena kuletsa kugwiritsa ntchito PFAS ponyamula chakudya.

Pamene malamulo akuchulukirachulukira, opanga akutenga njira zokhazikika ndikutembenukira ku njira zina zotetezeka. Makampani omwe akuchulukirachulukira tsopano adzipereka kupanga zopangira nzimbe zopanda PFAS, kugwirizanitsa ntchito zawo ndi zofuna za ogula kwinaku akutsatira malamulo osintha.

Pomaliza, Kukula komwe kukukulirakulira kwa nzimbe wopanda PFAS kukuwonetsa kuzindikira kwa ogula komanso udindo wa chilengedwe. Potengera njira zokometsera zachilengedwezi, anthu pawokha komanso makampani amatha kuthandizira kuti dziko lapansi likhale lathanzi lopanda zoyipa za PFAS. Pamene malamulo akusintha, akuyembekeza kuti makampani ambiri atengere machitidwe opanda PFAS, ndikupititsa patsogolo kusintha kwa zosankha zokhazikika.

Posankha nzimbe zamtundu wa PFAS zopanda nzimbe, anthu amatha kutenga nawo mbali pakukhala ndi thanzi labwino, kuchepetsa zinyalala ndikupanga tsogolo lokhazikika. Pamene tikuwona kusintha kwabwinoku, ndikofunikira kuti tipitilize kuthandizira opanga ndi opanga mfundo poyesetsa kupereka njira zina zotetezeka komanso zobiriwira.
