Pamene nkhawa zikukulirakulira pa zoopsa zomwe zingachitike pa thanzi ndi chilengedwe zokhudzana ndi perfluoroalkyl ndi polyfluoroalkyl substances (PFAS), pakhala kusintha kwa makina odulira nzimbe opanda PFAS. Nkhaniyi ikufotokoza zifukwa zomwe zachititsa kusinthaku, ikuwonetsa momwe PFAS imakhudzira thanzi ndi chilengedwe komanso ubwino wogwiritsa ntchito mbale zopanda PFAS zopangidwa kuchokera ku nzimbe.
Kuopsa kwa PFAS Zinthu zopangidwa ndi perfluoroalkyl ndi polyfluoroalkyl, zomwe zimatchedwa PFAS, ndi gulu la mankhwala opangidwa omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana komanso ogula chifukwa chokana kutentha, madzi, ndi mafuta.
Mwatsoka, zinthuzi sizimasweka mosavuta ndipo nthawi zambiri zimasonkhana m'chilengedwe komanso m'thupi la munthu. Kafukufuku wambiri wasonyeza kuti kukhudzana ndi PFAS kungakhale ndi zotsatirapo zoipa pa thanzi, kuphatikizapo khansa ya impso ndi ma testicular, kuwonongeka kwa chiwindi, kuchepa kwa kubereka, mavuto a chitukuko mwa makanda ndi ana, komanso kusokonekera kwa mahomoni.
Mankhwala amenewa apezekanso kuti akukhalabe m'chilengedwe kwa zaka zambiri, kuipitsa madzi ndi nthaka komanso kuopseza zachilengedwe.Zakudya Zopangira Masamba a NzimbePozindikira zotsatirapo zoipa za PFAS, ogula ndi mafakitale onse akufunafuna njira zina zotetezeka. Nsomba za nzimbe, zomwe zimapangidwa kuchokera ku njira yopangira shuga, zakhala njira yabwino komanso yosawononga chilengedwe m'malo mwa mbale zachikhalidwe zopangidwa ndi zinthu monga pulasitiki kapena Styrofoam.
Zakudya zophikira za nzimbe zimapangidwa kuchokera ku masagasi, zomwe zimatsalira pambuyo poti madzi a nzimbe achotsedwa. Zimawola, zimatha kupangidwa ndi manyowa ndipo sizifuna zinthu zatsopano kuti zipangidwe. Kuphatikiza apo, mbewu za nzimbe zimatha kulimidwa mwachangu, zomwe zimapangitsa kuti zikhale zokhazikika komanso zobwezerezedwanso.
Ubwino Wosakhala ndi PFAS Chimodzi mwa zifukwa zazikulu zomwe zikuwonjezera kufunikira kwa zida zopangira shuga zopanda PFAS ndikupewa zoopsa paumoyo. Opanga akusiya kugwiritsa ntchito PFAS popanga zinthu zawo kuti atsimikizire kuti zinthu zawo ndi zotetezeka komanso zopanda mankhwala oopsa. Ogula akudziwa bwino kufunika kochepetsa kukhudzana ndi PFAS ndipo akufunafuna njira zina zopanda PFAS.
Kufuna kumeneku kwapangitsa opanga kuti ayang'anenso momwe amagwirira ntchito ndikuyika ndalama muukadaulo wopanda PFAS, zomwe zapangitsa kuti pakhale kupezeka kwa njira zotetezeka za tebulo. Ubwino wa chilengedwe Kuwonjezera pa ubwino wa thanzi,Wopanda PFASmbale za nzimbezilinso ndi ubwino waukulu pa chilengedwe. Zipangizo zapulasitiki zophikira patebulo zimakhala ndi vuto lalikulu pa kasamalidwe ka zinyalala chifukwa zimatenga zaka mazana ambiri kuti ziwole ndipo nthawi zambiri zimathera m'malo otayira zinyalala, m'nyanja kapena m'malo otenthera zinyalala.
Mosiyana ndi zimenezi, zipangizo zodulira nzimbe ndi zopanda ntchito kwenikwenizowola komanso zophikidwa mu manyowaZimathandiza kuchepetsa kukakamizidwa kwa njira zoyendetsera zinyalala zomwe zawonongeka kale komanso zimathandiza kuti chuma chikhale chokhazikika komanso chozungulira.
Pogwiritsa ntchito njira zina zopanda PFAS, ogula amatha kusintha chilengedwe ndikupita patsogolo ku tsogolo labwino komanso lodalirika. Malamulo ndi zochita zamakampani Pozindikira zoopsa zomwe PFAS imabweretsa, olamulira m'maiko ena akutenga njira zochepetsera kugwiritsa ntchito mankhwala oopsa awa.
Mwachitsanzo, ku United States, bungwe la Environmental Protection Agency (EPA) lakhazikitsa malangizo azaumoyo a PFAS ena pankhani ya madzi akumwa, ndipo mayiko ena akukhazikitsa lamulo loletsa kapena kuletsa kugwiritsa ntchito PFAS m'mapaketi azakudya.
Pamene malamulo akukhwima kwambiri, opanga akugwiritsa ntchito njira zokhazikika komanso kugwiritsa ntchito njira zina zotetezeka. Makampani ambiri tsopano akudzipereka kupanga mbale za shuga zopanda PFAS, zomwe zikugwirizana ndi zomwe ogula akufuna komanso malamulo osintha.
Pomaliza, kufunikira kwakukulu kwa mbale za shuga zopanda PFAS kukuwonetsa chidziwitso cha ogula komanso udindo wawo pazachilengedwe. Mwa kugwiritsa ntchito njira zina zotetezera chilengedwe, anthu ndi mafakitale angathandize kuti dziko lapansi likhale lathanzi lopanda zotsatirapo zoyipa za PFAS. Pamene malamulo akusintha, yembekezerani makampani ambiri kuti agwiritse ntchito njira zopanda PFAS, zomwe zikuthandizira kusintha kwa njira zosungira mbale zokhazikika.
Posankha mbale za nzimbe zopanda PFAS, anthu amatha kutenga nawo mbali mwachangu pakusunga thanzi, kuchepetsa zinyalala ndikumanga tsogolo lokhazikika. Pamene tikuwona kusintha kwabwino kumeneku, ndikofunikira kupitiliza kuthandizira opanga ndi opanga mfundo pakuyesetsa kwawo kupereka njira zina zotetezeka komanso zobiriwira.
