Ingabe i-PFOA ikhona emaphoyiseni angaphandle?
Ukupheka yonke indawo, ikakhulukazi abapheki be-fat-fat, baye bathembela emaphoyiseni okugcoba njengendlela enhle yokupheka noma yokupheka ukudla, kusuka kuma-omelets nama-sauces kuya kumaqebelengwane e-Bundt aphethwe kahle, ngaphandle kokushiywa ngemuva kokuhlanza okunamandla okukhulu.
Ezweni lokupheka amafutha aphansi, ikakhulukazi, amaphini okugcoba angadingeki, ngoba ayidinga amafutha amancane noma angabikho okupheka. Kodwa hhayi okokuqala, kuphakanyiswe imibuzo mayelana nokuphepha kwe-cookware engekho, ikakhulukazi ngenxa yokukhathazeka kwezemvelo nge-perfluorooctanoic acid (PFOA) -wayaziwa nangokuthi i-C-8-ikhemikhali esetshenziselwa ukubopha ukugqoka okungenasiphakamiso epanini.
PFOA (C-8) noDuPont
Ekuqaleni kuka-2006, i-Environmental Protection Agency (EPA) yacela izinkampani eziyisishiyagalombili zaseMelika, kuhlanganise noDuPont, umenzi weTekhlon-brand nonstick cookware, ukuze asebenze ekuqothulweni kwe-PFOA-ukuthi babhalela i-carcinogen cishe-ngo-2015.
I-PFOA iboniswe ukuthi ibangelwa umdlavuza, isisindo sokuzalwa esincane kanye nesistimu yomzimba yokuzivikela ekhunjulwayo ezilwaneni ze-laboratory ezivezwe ngokwezinga eliphezulu le-PFOA.
Ucwaningo lubonise ukuthi amakhemikhali abe khona emazingeni aphansi egazini lama-9 kwabangu-10 baseMelika, nasegazini labaningi abasanda kuzalwa. Futhi nakuba imiphumela ye-PFOA emazingeni aphansi abantu ephikisanayo, kubonakala sengathi kukhona ukuxhumana phakathi kwe-PFOA kanye namazinga aphakanyiswe yi-cholesterol.
Okubaluleke nakakhulu, abanye abantu bathi i-PFOA ukuchayeka kubangelwa ukukhubazeka kwezinsana ezinganeni ezisebenzela isitshalo seTeflon ekuqaleni kwawo-1980.
Ukuthi amakhemikhali adluliselwa kanjani kubantu akucaci futhi, kuze kube manje, abukho ubufakazi bokuthi i-cookware engekho emthethweni, ikakhulukazi, iyisola.
Kodwa uDuPont ubelokhu enesiphambano se-EPA okwesikhashana futhi wayekhokhiswa kakhulu ngokusolakala ukuthi wayefihla idatha iminyaka eminingi ebuhlungu be-PFOA, futhi futhi engcolisa ukutholakala kwamanzi okuphuza e-Ohio River eduze nesitshalo saseWest Virginia.
Ukuzwa Ukushisa
Buyela emaphoyiseni angaphandle. Bobabili iDuPont kanye ne-EPA bathi abapheki abakhathazeki kakhulu uma basebenzisa kahle i-cookware yokuphepha.
Kunengxabano encane ukuthi, ngaphezu kwamazinga athile okushisa-okushisa kunombhoshongo womusi wamafutha okupheka noma iphuzu lapho kushaywa khona ukudla-ukugqoka okungapheli kuzokwehla futhi kukhululeke imfucuza ecolekile. Noma yikuphi ukuphakama okungaphansi kokushisa okwedlulele kuzonikeza amagesi anobuthi.
Ngokusho kweDuPont, i-cookware ne-Teflon yokugqoka ingubo yokugqoka inokunciphisa ukusetshenziswa okusetshenzisiwe okuphezulu okungu-500 F nokuthi ukuchithwa okuphawulekayo kwengubo kuyokwenzeka kuphela uma izinga lokushisa lidlula cishe ngo-660 F, okungahle kwenzeke uma amaphiko angapheli eshiyiwe noma engenalutho eshisayo ukushisa.
Umagazini we- Cook's Illustrated (isixhumanisi sibhalisile kuphela) kubikiwe ekuhlolweni kwezikhwama ezingapheli emzimbeni kaMeyi / June 2005 futhi wathola ukuthi ukushisa okunjalo okwedlulele kungafinyelelwa ngisho nokupheka ukudla okuthile ekushiseni okuphezulu (njenge-stir-fries).
Ezimweni eziningi, izinga lokushisa eliphezulu libhaliswe okwesibili noma ezimbili kuphela, liwela ngamadriki angama-200 njengoba ukudla kudluliselwa emhlabeni jikelele.
Ngonyaka we-2003 i-Environmental Working Group (EWG) ibike ukuthi ukugqoka okungapheli "kungafinyelela ama-degree angama-700 ku-3 kuya kwemizuzu emithathu, kukhishwa ama-gesi namakhemikhali angu-15, kubandakanya ama-carcinogens amabili."
Ukukhululwa kwemfucumfucu enobuthi kusuka ekuphekeni kwe-cookware kuyaziwa ukubulala izinyoni zezilwane emazingeni okushisa aphansi kakhulu-ezingaphansi kuka-464 F, ngokwe-EWG.
I-Nonstick Cookware ne-PFOA
Kodwa ngenkathi i-PFOA isetshenziselwa ukubopha ukugqoka kwe-cookware engapheliyo, i-DuPont ithi le makhemikhali ethile yabuye yabhujiswa enkambisweni yokushisa ekukhiqizeni, futhi ayikho emkhathini ophelile.
Izakhi zokulandelela ze-PFOA zitholakala, kodwa-ke, ekuvivinyweni okukodwa okwedlulele lapho izindawo ezibekwe khona zingaphansi komhlaba, kodwa izigqoko zanamuhla ezigqoke izikhuni zikhuni kunanini ngaphambili futhi zingakwazi ukumelana nokuphathwa okuncane ngokucophelela kunezizukulwane zangaphambilini ze-cookware.
Namathela Ngesikhwama Sezintambo
Kunezinkinga ezimbili lapha:
- Kungakhathaliseki ukuthi i-PFOA ikhona ekuphekeni kwe-cookware
- Ukukhishwa kwe-PFOA emvelweni
Ngokuqondene nokupheka okupheka, kubonakala sengathi akuncane isizathu sokukhipha izimbiza zethu namapane ethu okwamanje. Ngaphansi kokusetshenziselwa okuvamile, amapanki cishe aphephile.
Ngokuphathelene neDuPont, nezinye izinkampani zamakhemikhali ', ukubhekelelwa kwemvelo kuyathinteka, kubonakala sengathi kuthathwa isinyathelo esifanele ukuqinisekisa ukuthi ukukhishwa kwe-PFOA kuzokwenziwa kodwa kungakapheli iminyaka eyishumi.
Kungakhathaliseki ukuthi ukusetshenziswa kwe-PFOA emikhankeni engabheki kanye neminye imikhiqizo kuzoqedwa ngokuphelele ngokuhamba kwesikhathi akucacile, nakuba izinkampani ezibandakanya iDuPont kuthiwa zifuna ezinye izindlela ezifanele.
Ukusebenzisa i-Nonstick Cookware Ngokuphepha
- Ungalokothi ushiye amaphoyinti angaphandle kwezingodo ezingalindelwe emlilweni ovulekile noma eminye imithombo yokushisa.
- Ngesikhathi upheka, ungavumeli izinga lokushisa lishise ngaphezu kuka-450 F.
- Ungasebenzisi izitsha zensimbi ekuphekeni kwe-cookware.
- Geza i-cookware engekho ngesandla usebenzisa izihlungi ezingenabuthi kanye nezipanji (ungasebenzisi uboya be-steel).
- Ungagcini i-cookware engapheli phezulu komunye nomunye.
- Gcina izinyoni zezilwane eziphuma ekhishini.
