Uma uzwile noma ufunde mayelana nocwaningo lwakamuva lwendawo yaseSeattle ubuthi obisini lwebele (PFAS)Ngiqinisekile uzosaba.
Yize kuthusa ukuzwa ukuthi amakhemikhali abizwa nge-perfluoroalkyl ne-polyfluoroalkyl (PFAS) atholakala kumasampula obisi lwebele ahlolwa, ongoti bathi ukuncelisa kuseyiyona ndlela enempilo kokubili izingane kanye nomama. Yilokhu okudingeka ukwazi omama abasha.
Buyini lobu buthi be-PFAS?
I-PFAS ngamakhemikhali asetshenziswe amashumi eminyaka kuwo ukudla okusheshayo wrappers, amapani angagxili, igwebu elicisha umlilo, izingubo ezingangeni manzi, izimonyo, nendwangu engangenwa amabala esetshenziswa kosofa nomata.
Lezi zinto zibizwa ngokuthi "amakhemikhali angunaphakade" ngenxa yezibopho eziqinile phakathi kwama-athomu azo zivimbele ukuba zingabhidlizi. I-PFAS iphikelela emvelweni futhi iqongelela emizimbeni yethu. Ucwaningo luye lwabonisa ukuthi la makhemikhali okuhlobene nomdlavuza, amasosha omzimba abuthakathaka, ukwanda kwe-cholesterol, nezinkinga zegilo.
Lolu cwaningo lwatholani?
Lokhu kungokokuqala ukutadisha kwenziwa ngaphezu kweminyaka eyi-15 ukubona ukuthi i-PFAS ikhona yini obisini lwebele. Amasampula obisi lwebele avela kwabesifazane abangu-50 endaweni yaseSeattle ahlolwe ama-PFAS angu-39 ahlukene futhi atholakala equkethe i-16 yala makhemikhali. Amaphesenti ayikhulu amasampula aqukethe izinga elithile le-PFAS.
Yini abazali okufanele bayithathe kulolu cwaningo? Ingabe omama kufanele besabe ukuncelisa?
Angicabangi ukuthi omama kufanele besabe ukuncelisa.. Ngokuvamile, kuhle ukuqaphela ukungcola kwemvelo okungenzeka kube khona, kokubili ngokombono wezempilo yomphakathi kanye nokubuka komuntu ngamunye, mayelana nokucabanga ngempilo yakho siqu nokuthi singakunciphisa kanjani ukuchayeka ngokuvamile.
Siyazi ukuthi i-PFAS ingathinta ukusebenza kwamasosha omzimba, ikakhulukazi amasosha omzimba. Esikwaziyo ngobisi lwebele ukuthi luqukethe amasosha omzimba, kodwa futhi lunezici eziningi ezithinta amasosha omzimba. Nakuba lawa makhemikhali engase ehlise umsebenzi wokuzivikela wengane, ngokuqinisekile awenza ngeke iqede ngokuphelele imiphumela yokuvikela yobisi lwebele. Ubisi lwebele luqukethe [izici zokuzivikela ezifweni ezifana] nama-cytokines nama-interleukin avikela izifo zokuphefumula nezinye izifo.
Uma la makhemikhali enqwabelana emizimbeni yethu kukho konke ukuphila kwethu, ingabe kuyasiza ekunciphiseni ukuchayeka manje?
Yebo. Lawa ma-PFAS anqwabelana kuyo yonke impilo yakho, ngakho-ke ingane esanda kuzalwa nayo inesikhathi sokuphila ngaphambi kwayo, kanye nempilo yonke yokuchayeka nayo. Ukunciphisa ukuchayeka ekhaya ngangokunokwenzeka kuzosiza ukuthuthukisa impilo yesikhathi esizayo yanoma iyiphi ingane.
Ngokuvamile, siphila emphakathini onezimboni, ngakho-ke kuzoba nokuchayeka kwamakhemikhali. Ayikho indlela yokufika ekuchayekeni okuyiziro. Kodwa esingakwenza ukuzama ukunciphisa ukuchayeka ngangokunokwenzeka, ekhaya lomuntu, indlela yokuphila kanye nempilo yansuku zonke.
Kunezinto ezilula esikhuluma ngazo [ukusiza ukugwema ukuchayeka kwamakhemikhali] ezingaqondile ku-PFAS, njengokuthi khumula izicathulo uma sifika ekhaya, ukuhlanza amafreyimu amafasitela, ukugcina okhaphethi bengenasici, ukudla ukudla okusha nemifino uma kungenzeka, nokuzama ukugwema ukudla okugayiwe ngangokunokwenzeka.
Yiziphi ezinye zezinzuzo zokuncelisa?
Kulinganiselwa ukuthi bangakwazi nciphisa izifo zokuphefumula ezinganeni ngo-50% uma ukwazi ukuncelisa izinyanga ezine noma eziyisithupha. Futhi kukhona nobufakazi bokunciphisa izifo zesisu. Kukhona futhi izinzuzo ze-neurodevelopmental kanye ne-bonding.
bambelela kulokhu
Ngokuvumelana ne Centers for Disease Control and Prevention, izingane ezincela ibele zinengozi ephansi yokuba nesifuba somoya, isifo sikashukela sohlobo loku-1, izifo ezindlebeni, ukukhuluphala ngokweqile, izifo ezingathi sína zokuphefumula okuphansi, kanye nesifo sesisu. Omama abancelisa ibele banengozi encane yokuba nomfutho wegazi ophakeme, uhlobo lwesifo sikashukela sohlobo 2, nomdlavuza webele nowesibeletho.
Amathiphu okunciphisa ukuchayeka ku-PFAS
Nciphisa ukudla okungase kupakishwe kuma-wrapper aqukethe i-PFAS noma ezitsheni, njengokudla okunamafutha, ukudla okukhiphayo, nama-popcorn we-microwave.
Lapho upheka, ungasebenzisi izitsha ezingaqediwe; uma wenza kanjalo, lahla i-pan lapho ama-chips enamathela noma imihuzuko. (Amakhemikhali awasuki ku-coating uma iqinile.)
Uma ufuna ukuthenga ukhaphethi omusha noma ifenisha, cela umenzi ukuthi angagcobi izinto ezimelana namabala.
Hlola izithako ezisohlwini noma izingxenye zemikhiqizo yakho yokunakekela ukuze uthole amagama athi "fluoro" noma "perfluoros" futhi ugweme imikhiqizo enalawa makhemikhali. Eminye imikhiqizo, njengezinhlobo ezithile zezimonyo kanye nefloss yamazinyo, iqukethe i-PFAS.
