Bungwe la Environmental Working Group limalimbikitsa kuti musagwiritse ntchito floss ya mano yopangidwa ndi PTFE.Gululo linanena kuti “Kukumana ndi PFCs kwakhala kukugwirizana ndi khansa ya impso ndi testicular, cholesterol yambiri, kuchuluka kwa mahomoni a chithokomiro, matenda oopsa a mimba ndi preeclampsia, kunenepa kwambiri komanso kubadwa kochepa ....Ma PFC amawononga madzi, amalimbikira m'chilengedwe ndipo amakhalabe m'thupi kwa zaka zambiri.Otsogola opanga ma PFC avomereza kuti athetse ena mwa mankhwalawa kumapeto kwa chaka cha 2015, kuphatikiza PFOA, yodziwika kwambiri, yomwe idakhala yofunika kwambiri popanga polima.Tsoka ilo, palibe umboni kuti mankhwala omwe adalowa m'malo mwa PFOA ndi otetezeka kwambiri. ”
Madokotala amano akhala akutiuza kwa zaka zambiri kuti kugwiritsa ntchito floss kumachotsa plaque, chinthu chonga gel opangidwa ndi mabakiteriya omwe amapanga mano ndi pakati, komanso pansi pa chingamu.Amaganiziridwa kuti ndi gawo lofunikira kwambiri paukhondo wa mano chifukwa kutsuka kwabwinobwino sikuchotsa zolembera zonse.Ndipo ngati sichichotsedwa, imauma ndipo imatha kuyambitsa gingivitis kapena kutupa kwa mkamwa.M’kupita kwa nthaŵi, nkhama zimayamba kupatukana ndi mano, n’kupanga “matumba” oti akhoza kutenga matenda, n’kuwononga fupa n’kuthothoka mano.Flossing imasokoneza mabakiteriya, kuwayimitsa asanayambe kupanga plaque.Kafukufuku wosiyanasiyana wasonyeza kuti, kupatula kutayika kwa mano, matenda a chingamu ndi chiopsezo chachikulu cha matenda a Alzheimer's ndi kukumbukira.
Komabe, posachedwapa zakhala zikukayikitsa za phindu la kupukuta mano kuti achotse zomangira.Kufufuza kwa 2015 kochitidwa ndi bungwe lazofalitsa nkhani la Associated Press (AP) kudakhudza zopempha za Ufulu Wachidziwitso ku US Department for Health and Human Services (HHS) kupempha kafukufuku wotsogolera ku malingaliro ake mokomera kuwonda.HHS pambuyo pake idasiya upangiri mwakachetechete, ndipo Public Health England yanenanso kuti iwunikanso malangizo ake pakuwomba.M'kalata yopita kwa AP, boma la US lidavomereza kuti flossing silinafufuzidwepo.Izi zikuwoneka kuti sizowona kwenikweni, chifukwa AP idayang'ana maphunziro makumi awiri ndi asanu kuyerekeza kuphatikiza kwa misuwachi ndi floss zosiyanasiyana ndipo adapeza kuti umboni wa kuwonda ndi "wofooka, wosadalirika kwambiri," wamtundu "wotsika kwambiri", ndipo umakhala ndi "zapakati". kukhala ndi kuthekera kwakukulu kochita kukondera. ”
Ngakhale mutasankha kupitiriza kupitiriza floss pakali pano, ndinu olondola kukayikira mtundu wa floss ntchito, onse thanzi lanu ndi chilengedwe ndi ena chitukuko.
Dongosolo lina la mano limapangidwa kuchokera ku nayiloni, ulusi wopangidwa kuchokera ku mafuta a petroleum.Mafuta a petroleum ndi chinthu chosasunthika, kukumba ndi kupanga chomwe chakhala ndi zotsatira zowononga kwambiri nthaka, madzi apansi, madzi apansi, ndi zachilengedwe.Nayiloni imatenga pafupifupi zaka makumi asanu kuti iwonongeke m'chilengedwe, ndipo floss yotayidwa (makamaka ikaponyedwa m'chimbudzi) imatha kutseka ngalande, kuipitsa nyanja, ndi kuvulaza nyama zakutchire.Floss imakutidwanso ndi sera yopangidwa ndi petroleum.Anthu aku America amagula ma floss a mano opitilira 3 miliyoni chaka chilichonse, kotero izi ndizowonongeka kwambiri.
Ulusi wopangidwa kuchokera ku polytetrafluoroethylene (PTFE) ikukula kwambiri - ndipo imagulitsidwa ku maofesi a mano kuti aperekedwe kwa makasitomala.Anthu ambiri amachikonda chifukwa sichimang'ambika ndipo ndichosavuta "kutsetsereka" pakati pa mano othina ndi kuzungulira zingwe.
Zosakaniza zina zimatha kukhala zokometsera ndi zowonjezera zomwe zimasiyana ndi wopanga ndipo zingaphatikizepo fluoride.Chidule cha patent imodzi ya dental floss imati: "Porous, high strength (PTFE) dental floss imakutidwa ndi sera yaying'ono.Ngati mungafune, floss imathanso kuphatikizirapo mankhwala a tartar, anticaries, antiplaque ndi/kapena antibacterial actives ndi/kapena zovomerezeka mano monga kupukuta ndi zonyezimira, zoziziritsira, zonunkhiritsa ndi/kapena zoziziritsa kukhosi.”
Zonsezi zitha kukhala zovuta pa thanzi lathu, koma PTFE ndiye vuto lalikulu, m'malingaliro anga.Imaperekanso zokutira muzophika zopanda ndodo, pansi pa dzina lake la malonda la DuPont polima.Ngakhale chodetsa nkhaŵa chachikulu pa polima chinali kutulutsa poizoni pamene zophikira zikatenthedwa, mankhwala omwe amagwiritsidwa ntchito popanga, otchedwa perfluorooctanoic acid (PFOA), amabweretsa mavuto ena.PTFE ndi gulu la perfluorochemicals (PFCs), zomwe zakhala zowononga padziko lonse lapansi pakanthawi kochepa.Apezeka m'mizinda yathu, m'zilumba zakutali, m'nkhalango, ndi m'madera a polar, akuwonekera m'madzi akumwa ndi nyama zakutchire.
Kafukufuku akusonyezanso kuti pafupifupi anthu onse, mosasamala kanthu za msinkhu, ali ndi ma PFC ena m’magazi awo.Apezeka mu zitsanzo za mkaka wa m'mawere wa anthu, komanso m'magazi a ana obadwa kumene.
