The Environmental Working Group inokurudzira kusashandisa dental floss yakagadzirwa nePTFE.Boka racho rinoti “Kuratidzirwa kuPFCs kwave kuchibatanidzwa nekenza yeitsvo uye testicular, cholesterol yakakwira, utachiona husina kujairika hwemahomoni ethyroid, pamuviri-induced hypertension uye preeclampsia, kufutisa uye uremu hwekusununguka ....PFCs inosvibisa mvura, inorambira munharaunda uye inoramba iri mumuviri kwemakore.Vanotungamira vagadziri vePFCs vakabvuma kubvisa mamwe emakemikari aya pakupera kwa2015, kusanganisira PFOA, inonyanya kuzivikanwa, iyo yaimbove chinhu chakakosha mukugadzira polymer.Nehurombo, hapana humbowo hwekuti makemikari akatsiva PFOA akachengeteka zvakanyanya. "
Vanachiremba vemazino vave vachitiudza kwemakumi emakore kuti kushandisa mazino floss zvinobudirira kubvisa plaque, gel-sechinhu chakagadzirwa nebhakitiriya chinoumba pakati nepakati pemazino, uyewo pasi pegum line.Zvave zvichifungidzirwa kuti chikamu chakakosha chemaitiro edu ehutsanana hwemazino nekuti kukwesha kwakajairika hakubvisi plaque yese.Uye kana isina kubviswa, inoomesa uye inogona kukonzera gingivitis kana kuzvimba kwemazino.Pakupedzisira, mazino anotanga kuparadzana nemazino, achiita “homwe” dzinogona kutapukirwa, pakupedzisira dzichiparadza bhonzo zvoita kuti mazino arasikike.Flossing inovhiringa bhakitiriya, ichiimisa isati yagadzira plaque.Zvidzidzo zvakasiyana-siyana zvakaratidza kuti, kunze kwekurasikirwa kwezino, chirwere chemazino chinhu chikuru chengozi yeAlzheimer's uye ndangariro nyaya.
Nekudaro, kukahadzika kwakakandwa nguva pfupi yadarika pakubatsira kwekutsvaira kwemazino kubvisa plaque.Ongororo yakaitwa muna 2015 nesangano renhau reAssociated Press (AP) yaisanganisira zvikumbiro zveRusununguko rweRuzivo kuDhipatimendi reUS reHutano neHuman Services (HHS) richikumbira tsvakiridzo inotungamira kurudziro yaro mukufarira kupuruzira.HHS yakazosiya zano racho chinyararire, uye Public Health England yataurawo kuti ichange ichiongorora kutungamira kwayo pakufambisa.Mutsamba yakanyorerwa AP, hurumende yeUS yakabvuma kushanda kweiyo flossing hakuna kumboongororwa.Izvi zvinoita sezvisiri chokwadi zvachose, nekuti AP yakatarisa zvidzidzo makumi maviri neshanu achienzanisa misanganiswa yemabhurashi emazino akasiyana uye floss ndokuona kuti humbowo hwekupuruzira "husina simba, hahuna kuvimbika," hwemhando "yakaderera kwazvo", uye inotakura "zvine mwero." kune mukana mukuru wekusarura."
Kunyangwe iwe ukafunga kuramba uchienderera mberi ne floss ikozvino, wakarurama kubvunza kuti ndeupi rudzi rwe floss yekushandisa, kune zvese hutano hwako uye iyo yezvakatipoteredza uye yakasara budiriro.
Imwe dental floss inogadzirwa kubva naironi, faibha yekugadzira inotorwa kubva muzvigadzirwa zvepetroleum.Petroleum chinhu chisina kugadzikana, kucherwa nekugadzirwa kwacho kwakave nekukanganisa kukuru pavhu, pasi pemvura, pamusoro pemvura, uye ecosystem.Nylon inotora makore angangoita makumi mashanu kuti iparare mumhoteredzo, uye floss yakaraswa (kunyanya kana yakandwa muchimbuzi) inogona kuvhara masiweji, kusvibisa madziva, nekukuvadza mhuka dzesango.Floss inowanzoputirwa nepetroleum-based wax.MaAmerican anotenga anopfuura mamirioni matatu mamaira emazino floss gore rega rega, saka uku kukuvadza kwakanyanya.
Floss yakagadzirwa kubva ku polytetrafluoroethylene (PTFE) iri kuramba ichizivikanwa - uye inotengeswa kumahofisi emazino kuti apiwe vatengi.Vanhu vazhinji vanochifarira nekuti hachitsemuke uye chiri nyore “kutsvedza” pakati pemazino akaomarara uye nekupoterera simbi.
Zvimwe zvinoshandiswa zvinogona kuva zvinonaka uye zvinowedzera zvinosiyana nemugadziri uye zvinogona kusanganisira fluoride.Pfupiso yeimwe dental floss patent inoti: “Porous, high strength (PTFE) dental floss yakaputirwa nemicro-crystalline wax.Kana zvichidiwa, floss inogona zvakare kubatanidza imwe kana kupfuura inoshanda tartar control, anticaries, antiplaque uye/kana antibacterial actives uye/kana mazino anogamuchirwa emishonga akadai sekuporishesa uye abrasive agents, coolant, flavour and/kana coagulants.”
Izvo zvese zvinogona kunetsa kune hutano hwedu, asi PTFE ndiro dambudziko guru, mumaonero angu.Inopawo iyo yekuputira mune isiri-stick cookware, pasi peiyo DuPont yekutengesa zita polymer.Kunyangwe iyo yakanyanya kunetseka pamusoro pepolymer kwave kuburitswa kwehupfu kana cookware yanyanya kupisa, kemikari inoshandiswa mukugadzirwa kwayo, inonzi perfluorooctanoic acid (PFOA), inogadzira mamwe matambudziko.PTFE ndeyekirasi yeperfluorochemicals (PFCs), iyo yave inosvibisa pasi rose munguva pfupi.Vakawanwa mumaguta edu, pazvitsuwa zviri kure, mumasango, uye munzvimbo dzine polar, vachiratidzira mumvura yokunwa nemhuka dzomusango.
Ongororo dzinoratidzawo kuti vanenge vanhu vese, zvisinei nezera, vane mamwe maPFC muropa ravo.Iwo akawanikwa mumasampuli emukaka wezamu wevanhu, uye muropa revana vachangoberekwa.
