IQela eliSebenzayo lokusiNgqongileyo licebisa ngokuchasene nokusetyenziswa kwefloss yamazinyo eyenziwe nge-PTFE.Eli qela lithi “Ukuchanabeka kwii-PFCs kuye kwanxulunyaniswa nomhlaza wezintso namatyhalarha, icholesterol eninzi, umlinganiselo ongaqhelekanga wamadlala edlala lengqula, uxinezeleko lwegazi olubangelwa kukukhulelwa kunye nepreeclampsia, ukutyeba ngokugqithiseleyo nokuzalwa kobunzima obuphantsi ....Ii-PFCs zingcolisa amanzi, ziyazingisa kokusingqongileyo kwaye zihlala emzimbeni iminyaka.Abavelisi abahamba phambili be-PFCs baye bavuma ukukhupha ezinye zezi khemikhali ekupheleni kwe-2015, kuquka i-PFOA, eyona nto idume kakhulu, eyayisetyenziselwa ukuba ibe yinto ephambili ekwenzeni i-polymer.Ngelishwa, abukho ubungqina bokuba iikhemikhali ezithathe indawo yePFOA zikhuselekile. ”
Oogqirha bamazinyo bebesixelela kangangamashumi eminyaka ukuba ukusetyenziswa kwefloss yamazinyo ngokufanelekileyo kususa i-plaque, into efana nejeli eyenziwe ngebhaktiriya eyenza ngaphakathi naphakathi kwamazinyo, kunye nangaphantsi kwentsini.Kucingelwa ukuba yinxalenye ebalulekileyo yenkqubo yethu yococeko lwamazinyo kuba ukuxubha okuqhelekileyo akulisusi lonke i-plaque.Yaye ukuba ayisuswanga, iyaqina kwaye inokubangela i-gingivitis okanye ukuvuvukala kweentsini.Ekugqibeleni, iintsini ziqalisa ukwahluka emazinyweni, zenze “iipokotho” ezinokosuleleka, ekugqibeleni zitshabalalise amathambo kuze kuphumele ekuphumeni kwamazinyo.I-flossing iyayiphazamisa ibhaktheriya, iyimise ngaphambi kokuba idale i-plaque.Izifundo ezahlukeneyo zibonise ukuba, ngaphandle kokulahleka kwamazinyo, isifo seentsini singumngcipheko omkhulu we-Alzheimer kunye nemiba yememori.
Nangona kunjalo, amathandabuzo asanda kwenziwa malunga nokuba luncedo kokutyalwa kwamazinyo ukususa ngokufanelekileyo i-plaque.Uphando lwe-2015 ngumbutho weendaba i-Associated Press (AP) ibandakanya izicelo zeNkululeko zoLwazi kwiSebe lezeMpilo lezeMpilo kunye neeNkonzo zoLuntu (HHS) e-US ecela uphando olukhokelela ekunconyweni kwayo ekuthandeni i-flossing.I-HHS emva koko yalilahlisa ingcebiso ngokuzolileyo, kwaye iMpilo yoLuntu yaseNgilani ikwathe iza kuphonononga eyayo isikhokelo malunga neflossing.Kwileta eya kwi-AP, urhulumente wase-US wavuma ukuba ukusebenza kweflossing akuzange kwenziwe uphando.Oko kubonakala kungeyonyani ngokupheleleyo, kuba i-AP ijonge kwizifundo ezingamashumi amabini anesihlanu ethelekisa indibaniselwano yeebhrashi zamazinyo ezahlukeneyo kunye nefloss kwaye yafumanisa ukuba ubungqina beflossing "bubuthathaka, abuthembekanga kakhulu," bomgangatho "ophantsi kakhulu", kwaye buphethe "ophakathi". kumathuba amakhulu okukhetha.”
Nokuba uthatha isigqibo sokuqhubeka nokubhabha okwangoku, ulungile ukubuza ukuba loluphi uhlobo lwefloss onokuthi ulusebenzise, kwimpilo yakho nakwimeko engqongileyo kunye nayo yonke impucuko.
Enye ifloss yamazinyo yenziwe ngenayiloni, ifayibha yokwenziwa ephuma kwiimveliso zepetroleum.I-Petroleum sisixhobo esingenazinzo, ukutsalwa kunye nokuveliswa kwayo okuye kwanempembelelo enkulu eyingozi emhlabeni, kumanzi aphantsi komhlaba, amanzi angaphezulu, kunye ne-ecosystem.Inayiloni ithatha malunga neminyaka engamashumi amahlanu ukudilika kokusingqongileyo, kwaye ifloss elahliweyo (ingakumbi xa iphoswe kwindlu yangasese) inokuvala imijelo ehambisa amanzi amdaka, ingcolise amachibi, kwaye yenzakalise izilwanyana zasendle.Ifloss isoloko iqatywe ngewax esekwe kwipetroleum.Abantu baseMelika bathenga ngaphezulu kwezigidi ezithathu zeemayile zefloss yamazinyo minyaka le, ke lo monakalo mkhulu.
Ifloss eyenziwe nge-polytetrafluoroethylene (PTFE) iya ithandwa kakhulu - kwaye ithengiswa kwiiofisi zamazinyo ukuba zinikwe abathengi.Abantu abaninzi bayayithanda ngenxa yokuba ayiqhekezi kwaye kulula “ukutyibilika” phakathi kwamazinyo aqinileyo kunye neentsimbi zokujikwa.
Ezinye izithako zinokuba yincasa kunye nezongezo ezihluka kumenzi kwaye zinokubandakanya i-fluoride.Isishwankathelo selungelo elilodwa lomenzi wefloss yamazinyo sifundeka ngolu hlobo: “I-Porous, high strength (PTFE) ifloss yamazinyo iqatywe nge-micro-crystalline wax.Ukuba kuyanqweneleka, ifloss isenokuthi ibandakanye ulawulo lwetartar olusebenzayo olunye okanye ngaphezulu, iianticaries, antiplaque kunye/okanye antibacterial actives kunye/okanye iiarhente ezamkelekileyo ngokwamazinyo ezifana nokupolisha kunye ne-abrasive agents, izipholisi, izithambiso kunye/okanye iicoagulants.”
Ezo zonke zinokuba yingxaki kwimpilo yethu, kodwa i-PTFE yeyona ngxaki inkulu, ngokoluvo lwam.Ikwabonelela ngokutyabeka kwi-cookware engeyiyo intonga, phantsi kwegama lorhwebo le-DuPont yepolymer.Nangona eyona nto ixhalabisayo kwipolymer ibe kukukhutshwa kweetoxin xa i-cookware ishushu kakhulu, imichiza esetyenziswa ekwenzeni kwayo, ebizwa ngokuba yi-perfluorooctanoic acid (PFOA), idala ezinye iingxaki.I-PTFE yeyodidi lwe-perfluorochemicals (PFCs), eziye zaba zingcoliso zehlabathi ngexesha elifutshane.Ziye zafunyanwa kwizixeko zethu, kwiziqithi ezikude, emahlathini, nakwimimandla epholileyo, zibonakala kumanzi okusela kunye nezilwanyana zasendle.
Uhlolisiso lukwabonisa ukuba phantse bonke abantu, kungakhathaliseki ukuba badala kangakanani na, banePFCs ezithile egazini labo.Ziye zafunyanwa kwiisampuli zobisi lwebele lomntu, kunye negazi leentsana ezisanda kuzalwa.
