Ukuba uvile okanye ufunde malunga nophando lwamva nje lwendawo yaseSeattle iityhefu kubisi lwebele (PFAS)Ndiqinisekile uya koyika.
Nangona isothusa ukufunda ukuba iikhemikhali ezibizwa ngokuba yi-perfluoroalkyl kunye ne-polyfluoroalkyl (PFAS) zifunyenwe kwiisampuli zobisi lwebele ezivavanyiweyo, iingcali zithi ukuncancisa kuseyeyona ndlela isempilweni zombini iintsana noomama. Oku koko oomama abatsha kufuneka bayazi.
Ziziphi ezi tyhefu zePFAS?
I-PFAS ziikhemikhali eziye zasetyenziswa amashumi eminyaka ukutya okusonga ngokukhawuleza, iipani ezingabotshelelwanga, ugwebu olucima umlilo, impahla engangeni manzi, izinto zokuthambisa, namalaphu angangenwa mabala asetyenziswa kwiisofa neekhaphethi.
Ezi zinto zibizwa ngokuba "iikhemikhali ngonaphakade" ngenxa yobudlelwane obuqinileyo phakathi kweeathom zabo zithintele ekuqhekekeni. I-PFAS iyaqhubeka nokusingqongileyo kwaye iqokelele emizimbeni yethu. Uphando lubonise ukuba ezi khemikhali zinjalo ezinxulumene nomhlaza, ukudodobala kwenkqubo yomzimba yokuzikhusela kwizifo, ukwanda kwecholesterol nengxaki yedlala lengqula.
Yintoni efunyenwe luphononongo?
Le yeyokuqala kufunda iqhutywe ngaphezulu kweminyaka eyi-15 ukubona ukuba iPFAS ikhona na kubisi lwebele. Iisampulu zobisi lwebele ezivela kwi-50 yabasetyhini kwindawo yase-Seattle zavavanywa kwii-PFAS ezahlukeneyo ze-39 kwaye zafunyanwa ziqulethe i-16 yale michiza. Ikhulu leepesenti leisampulu zinenqanaba elithile lePFAS.
Yintoni ekufuneka abazali bayithathe kwesi sifundo? Ngaba oomama kufuneka boyike ukuncancisa?
Andiqondi ukuba oomama kufuneka boyike ukuncancisa.. Ngokubanzi, kulungile ukuqaphela ungcoliseko lokusingqongileyo olunokuthi lubekho, kokubini ngokwembono yezempilo yoluntu nakwimbono yomntu ngamnye, malunga nokucinga ngobomi bakho kunye nendlela esinokunciphisa ngayo ukutyhileka ngokubanzi.
Siyazi ukuba iPFAS inokuchaphazela ukusebenza komzimba, ngakumbi izilwa-buhlungu. Into esiyaziyo ngobisi lwebele kukuba luqulethe izilwa-buhlungu, kodwa lukwanazo nezinye izinto ezininzi ze-immunological. Nangona ezi khemikhali zinokuthi zinciphise umsebenzi wokuzivikela womntwana, ngokuqinisekileyo ayiyi kuphelisa ngokupheleleyo imiphumo yokukhusela yobisi lwebele. Ubisi lwebele luqulethe [imiba yamajoni omzimba anjenge] cytokines kunye ne-interleukins ezikhusela ukosuleleka kwimiphunga nolunye usulelo.
Ukuba ezi khemikhali ziqokelelana emizimbeni yethu kubo bonke ubomi, ngaba kuyanceda ukunciphisa utyhileko ngoku?
Ewe, ezi PFAS ziqokelelana kubomi bakho bonke, ngoko ke usana olusandul' ukuzalwa lunobomi phambi kwabo, kunye nobomi bokuvezwa ngokunjalo. Ukunciphisa i-exposures ekhaya kangangoko kunokwenzeka kuya kunceda ukuphucula impilo yekamva lomntwana.
Ngokubanzi, siphila kuluntu oluhambele phambili kwezoshishino, ngoko kuya kubakho ukubonakaliswa kweekhemikhali. Akukho ndlela yokufumana i-zero exposure. Kodwa into esinokuyenza kukuzama ukunciphisa utyhileko kangangoko sinakho, kwikhaya lomntu, indlela yokuphila kunye nobomi bemihla ngemihla.
Kukho izinto ezilula esithetha ngazo [ukunceda ukunqanda ukuvezwa kweekhemikhali] ezingathanga ngqo kwiPFAS, njengazo khulula izihlangu zakho xa sifika ekhaya, ukucoca iifreyimu zeefestile, ukugcina iikhaphethi zicocekile, ukutya ukutya okutsha nemifuno xa kunokwenzeka, nokuzama ukukuphepha ukutya okugayiweyo kangangoko kunokwenzeka.
Ziziphi ezinye zeengenelo zokuncancisa?
Kuqikelelwa ukuba babenako ukunciphisa usulelo lokuphefumla ebantwaneni ngama-50% ukuba unokuncancisa iinyanga ezine okanye ezintandathu. Kwaye kukho nobungqina bokuncitshiswa kwezifo zesisu. Kukho neenzuzo ze-neurodevelopmental kunye ne-bonding.
bambelela kule nto
Ngoku ka Amaziko oLawulo lweSifo kunye noThintelo, iintsana ezincanciswayo zisengozini ephantsi yokuba nesifuba, uhlobo loku-1 lweswekile, ukosulelwa zindlebe, ukutyeba ngokugqithiseleyo, izifo ezinzulu zokuphefumla, kunye nesifo sesisu. Oomama abancancisayo banomngcipheko omncinci wokuba noxinzelelo lwegazi oluphezulu, uhlobo lwe-2 yeswekile, kunye nomhlaza webele kunye ne-ovarian.
Iingcebiso zokunciphisa ukuvezwa kwiPFAS
Nciphisa ukutya okunokuthi kupakishwe kwii-wrappers ezine-PFAS okanye kwizikhongozeli, ezinjengokutya okunamafutha, ukutya okutyayo, kunye ne-microwave popcorn.
Xa upheka, musa ukusebenzisa izinto zokupheka ezingakhuni; ukuba wenza, yilahle ipani kude xa chips yokwambathisa okanye imikrwelo. (Iikhemikhali azisuki kwi-coating xa icocekile.)
Ukuba ufuna ukuthenga ikhaphethi entsha okanye ifenitshala, cela umenzi wayo ukuba angaqabelisi izinto zokugquma izinto ezikwaziyo ukumelana namabala.
Jonga izithako ezidwelisiweyo okanye amacandelo emveliso yakho yokhathalelo lwamagama "fluoro" okanye "perfluoros" kwaye uphephe iimveliso eziqulathe ezi khemikhali. Ezinye iimveliso, ezinje ngeempawu ezithile zokuthambisa kunye nefloss yamazinyo, zinePFAS.
