PTFE Floss

Environmental Working Group pom zoo kom siv cov tshuaj txhuam hniav ua nrog PTFE.Cov pab pawg tau hais tias "Kev cuam tshuam rau PFCs tau cuam tshuam nrog rau lub raum thiab qog nqaij hlav qog noj ntshav, cov roj cholesterol siab, cov thyroid hormone tsis txawv txav, kev xeeb tub vim mob ntshav siab thiab preeclampsia, rog rog thiab yug me nyuam qis....PFCs qias neeg dej, tsis tu ncua nyob rau hauv ib puag ncig thiab nyob twj ywm hauv lub cev rau xyoo.Cov tuam txhab ua lag luam ntawm PFCs tau pom zoo rau theem tawm qee cov tshuaj no los ntawm qhov kawg ntawm 2015, suav nrog PFOA, qhov tsis zoo tshaj plaws, uas tau siv los ua cov khoom tseem ceeb hauv kev ua polymer.Hmoov tsis zoo, tsis muaj pov thawj tias cov tshuaj uas tau hloov PFOA muaj kev nyab xeeb dua. "

Cov kws kho hniav tau qhia peb ntau xyoo lawm tias kev siv cov tshuaj txhuam hniav zoo tshem tawm cov quav hniav, ib yam khoom zoo li gel ua los ntawm cov kab mob uas tsim rau ntawm cov hniav, nrog rau hauv qab ntawm cov pos hniav.Nws tau raug xav tias yog ib feem tseem ceeb ntawm peb txoj kev tu hniav vim kev txhuam hniav ib txwm tsis tshem tag nrho cov quav hniav.Thiab yog hais tias nws tsis raug tshem tawm, nws hardens thiab ua rau gingivitis los yog o ntawm cov pos hniav.Thaum kawg, cov pos hniav pib cais tawm ntawm cov hniav, tsim "pockets" uas tuaj yeem kis tus kab mob, thaum kawg ua rau cov pob txha thiab ua rau cov hniav poob.Flossing cuam tshuam cov kab mob, nres nws ua ntej nws tuaj yeem tsim cov quav hniav.Ntau yam kev tshawb fawb tau pom tias, ib sab ntawm cov hniav poob, kab mob ntawm cov pos hniav yog ib qho kev pheej hmoo loj rau Alzheimer's thiab teeb meem nco.

Txawm li cas los xij, tsis ntev los no tsis ntev los no tau muab pov rau ntawm qhov muaj txiaj ntsig ntawm kev kho hniav kom zoo tshem cov quav hniav.Kev tshawb nrhiav xyoo 2015 los ntawm lub koom haum xov xwm Associated Press (AP) koom nrog Kev ywj pheej ntawm cov ntaub ntawv thov mus rau US Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab Kev Pabcuam Tib Neeg (HHS) thov rau kev tshawb fawb ua rau nws pom zoo rau kev siv tshuaj txhuam hniav.HHS tom qab ntawd ntsiag to tso cov lus qhia, thiab Public Health England kuj tau hais tias nws yuav tshuaj xyuas nws tus kheej cov lus qhia ntawm kev siv tshuaj txhuam hniav.Hauv tsab ntawv mus rau AP, tsoomfwv Meskas tau lees paub qhov ua tau zoo ntawm kev siv tshuaj txhuam hniav tsis tau tshawb fawb.Qhov ntawd zoo li tsis muaj tseeb, vim tias AP tau saib nees nkaum tsib qhov kev tshawb fawb sib piv cov kev sib txuas ntawm ntau yam txhuam hniav thiab txhuam hniav thiab pom tias cov pov thawj rau kev txhuam hniav yog "tsis muaj zog, tsis muaj kev ntseeg siab," ntawm "tsawg" zoo, thiab nqa "ib nrab. rau qhov muaj peev xwm loj rau kev tsis ncaj ncees. "

Txawm hais tias koj txiav txim siab txuas ntxiv mus txuas ntxiv rau tam sim no, koj muaj cai nug seb hom xov tooj twg siv, rau koj txoj kev noj qab haus huv thiab ib puag ncig thiab lwm yam kev vam meej.

Qee cov tshuaj txhuam hniav yog tsim los ntawm nylon, hluavtaws fiber ntau tau los ntawm cov khoom siv roj av.Petroleum yog ib qho khoom siv tsis ruaj khov, kev rho tawm thiab kev tsim khoom uas tau muaj kev cuam tshuam loj rau cov av, dej hauv av, dej saum npoo av, thiab ecosystems.Nylon yuav siv sij hawm li tsib caug xyoo los rhuav tshem hauv ib puag ncig, thiab muab cov ntaub ntawv pov tseg (tshwj xeeb tshaj yog thaum nws muab pov rau hauv chav dej) tuaj yeem thaiv cov kav dej, cov pas dej ua paug, thiab ua phem rau cov tsiaj qus.Floss kuj feem ntau coated nrog roj av siv quav ciab.Cov neeg Amelikas yuav ntau tshaj peb lab mais ntawm cov hniav txhuam hniav txhua xyoo, yog li qhov no yog qhov kev puas tsuaj loj heev.

Floss ua los ntawm polytetrafluoroethylene (PTFE) tau dhau los ua neeg nyiam - thiab tau ua lag luam rau cov chaw kho hniav kom muab rau cov neeg siv khoom.Muaj coob tus neeg nyiam nws vim nws tsis shred thiab yooj yim rau "glide" ntawm cov hniav nruj thiab ib ncig ntawm braces.

Lwm cov khoom xyaw tuaj yeem yog flavors thiab additives uas txawv nrog cov chaw tsim khoom thiab tuaj yeem suav nrog fluoride.Cov ntsiab lus ntawm ib qho kev kho hniav patent nyeem: "Ntxhiab, siab zog (PTFE) cov hniav txhuam hniav yog coated nrog micro-crystalline wax.Yog tias xav tau, cov ntaub nplaum kuj tseem tuaj yeem suav nrog ib lossis ntau dua kev tswj hwm tartar, tshuaj tiv thaiv kab mob, tshuaj tiv thaiv kab mob thiab / lossis cov kab mob tua kab mob thiab / lossis cov khoom siv kho hniav xws li polishing thiab abrasive agents, coolants, flavorants thiab / lossis coagulants.

Txhua tus tuaj yeem ua teeb meem rau peb txoj kev noj qab haus huv, tab sis PTFE yog qhov teeb meem loj tshaj plaws, hauv kuv lub tswv yim.Nws kuj tseem muab cov txheej txheem hauv cov khoom siv tsis-stick, raws li nws lub npe lag luam DuPont polymer.Txawm hais tias qhov kev txhawj xeeb tseem ceeb ntawm polymer tau tso tawm cov co toxins thaum cookware overheated, cov tshuaj siv hauv nws cov khoom siv, hu ua perfluorooctanoic acid (PFOA), tsim lwm yam teeb meem.PTFE belongs rau chav kawm ntawm perfluorochemicals (PFCs), uas tau dhau los ua cov pa phem thoob ntiaj teb hauv lub sijhawm luv luv.Lawv tau pom nyob rau hauv peb lub zos, ntawm tej thaj chaw deb Islands tuaj, nyob rau hauv hav zoov, thiab nyob rau hauv lub polar cheeb tsam, tshwm sim nyob rau hauv cov dej haus thiab cov tsiaj qus.

Cov kev tshawb fawb tseem qhia tau tias yuav luag txhua tus neeg, tsis hais hnub nyoog li cas, muaj qee qhov PFCs hauv lawv cov ntshav.Lawv tau pom nyob rau hauv cov qauv ntawm tib neeg cov kua mis, thiab nyob rau hauv cov ntshav ntawm cov me nyuam mos.
