Xyoo tsis ntev los no, ntau tus kws tshawb fawb thiab cov neeg siv khoom zoo ib yam tau txhawj xeeb txog kev noj qab haus huv tshwm sim los ntawm kev kis mus rau bisphenol-A (BPA). BPA yog tshuaj lom neeg pom nyob hauv ntau yam khoom yas, txawm hais tias muaj coob ntxiv ntawm cov khoom cim "BPA dawb" tam sim no muaj. Koj tuaj yeem zam ntau yam yas uas muaj BPA los ntawm kev nyeem cov ntawv, thiab txwv koj qhov muaj peev xwm kis tau rau BPA los ntawm kev hloov qee yam khoom xaiv thiab tus cwj pwm. Txawm li cas los xij, koj yuav tsum tau kawm qhov teeb meem rau koj tus kheej, thiab txiav txim siab tias koj ntseeg nws tseem ceeb npaum li cas kom zam dhau BPA, thiab muaj kev nyab xeeb npaum li cas koj xav tias ntau yam "BPA dawb" yas yuav yog.
Cov kauj ruam
Ntu 1 ntawm 3: Txheeb Plastics nrog BPA
Kauj Ruam 1. Txheeb xyuas cov khoom yas rau daim ntawv lo
Ntau yam khoom yas, thiab tshwj xeeb tshaj yog cov khoom siv rau khoom noj lossis dej haus lossis menyuam cov khoom ua si, muaj cov lej cim uas tuaj yeem qhia koj yog tias lawv muaj BPA. Saib hauv qab ntawm cov khoom lag luam rau tus lej los ntawm ib rau xya (1-7) puag ncig los ntawm daim duab peb sab ua los ntawm peb tus xub xub (feem ntau hu ua "cim rov ua dua tshiab").
- Cov khoom nrog tus lej 3, 6, thiab tshwj xeeb tshaj yog 7 feem ntau yuav muaj BPA. Cov khoom nrog 1, 2, 4, lossis 5 feem ntau tsis muaj BPA.
- Daim ntawv "BPA pub dawb" ntawm cov khoom lossis ntim khoom, ua ke nrog ib tus lej "nyab xeeb dua" rov ua dua, yog koj qhov kev nyab xeeb tshaj plaws kom zam dhau BPA.
Kauj Ruam 2. Txheeb xyuas cov khoom siv polycarbonate
BPA tau siv los muab qee qhov "muab" rau cov yas yas txhawm rau txhawm rau txo qis tawg thiab tawg, thiab cov yas nruj feem ntau yog ua los ntawm polycarbonates. Yog tias cov khoom yas muaj tus lej rov ua dua “7” thiab/lossis muaj cim “PC,” nws yog polycarbonate thiab yuav muaj BPA ntau dua.
- Yog tias cov khoom yas tau nruj thiab pob tshab - piv txwv li, cov thawv ntim khoom noj rov siv tau - qhov txawv yog qhov zoo uas nws yog polycarbonate uas yuav muaj BPA.
- Cov mos mos dua, hloov pauv tau, thiab cov yas tsis zoo feem ntau tsis yog polycarbonates thiab tsawg dua yuav muaj BPA. Tab sis ib txwm saib rau daim ntawv lo.
Kauj Ruam 3. Pov tseg cov khoom yas qub
BPA tau siv txij li xyoo 1950s lig, yog li muaj qhov sib txawv uas koj lub hnub nyoog "khob sippy" lossis koj tus pog yawg lub tais yas yas ntim khoom ntim ntim muaj BPA. Cov khoom qub tsis zoo li yuav muaj cov cim cim rau ib yam nkaus.
- Coob leej neeg tshwj xeeb txhawj xeeb txog BPA raug rau menyuam yaus. BPA tau txwv hauv lub raj mis menyuam yaus thiab menyuam yaus lub khob sippy los ntawm FDA hauv Asmeskas xyoo 2012, thiab yav dhau los hauv Tebchaws Europe. Yog tias koj muaj lub raj mis yas yas qub, xav tias lawv muaj BPA thiab muab pov tseg.
- Kev khawb, khaus khaus thiab raug dua, thiab rov ua kom sov ntau dua ua rau tso BPA ntau dua los ntawm cov khoom yas. Qhov no yog lwm qhov laj thawj los txiav txim siab pov tseg cov khoom qub, siv tau zoo uas yuav muaj BPA.
Ntu 2 ntawm 3: Txwv Tsis Pub Muaj BPA Raug
Kauj Ruam 1. Xaiv cov zaub mov thiab dej haus uas tsis yog yas
Ua ntej yuav siv cov yas yas thoob plaws, txhua yam los ntawm cov menyuam lub raj mis mus rau cov tais sib xyaw feem ntau yog ua los ntawm cov khoom siv xws li iav, ceramic, thiab stainless hlau. Raws li kev txhawj xeeb txog BPA thiab lwm yam tshuaj lom neeg hauv cov yas tau loj tuaj, yog li ntawd tseem muaj kev lag luam rau cov khoom noj thiab dej haus ua los ntawm cov ntim khoom sib hloov no, uas tsis ua rau cov khoom puas tsuaj.
- Yog tias txawm tias tsis muaj BPA-dawb lub raj mis ua rau koj txhawj xeeb, piv txwv li, muaj cov iav tshiab xaiv uas suav nrog lub tes tsho silicone sab nraud kom txwv tsis pub tawg.
- Nco ntsoov, txawm li cas los xij, ntau lub kaus poom hlau siv rau khoom noj thiab dej haus (zoo li taum thiab npias) muaj cov kab yas uas muaj BPA. Kev noj zaub mov tsis tu ncua los ntawm cov ntim khoom zoo li tsawg kawg ib ntus nce qib BPA ntshav. Cov kaus poom feem ntau tsis muaj cov cim qhia txog kev siv (lossis tsis muaj) ntawm BPA linings, tab sis koj tuaj yeem pom cov npe ntawm cov tuam ntxhab uas tsawg kawg thov tsis txhob siv BPA.

Kauj Ruam 2. Txwv kev siv cua sov lossis ua kom huv nrog cov yas
Txawm hais tias koj cov khoom yas tau tshaj tawm tias yog "microwave nyab xeeb" lossis "tshuab ntxuav tais diav muaj kev nyab xeeb," qhov kub siab ua rau cov yas tsis muaj zog thiab pab txhawb kev tso tshuaj lom neeg zoo li BPA. Tshuaj hnyav los yog nplawm thiab txhuam uas ua rau khawb tuaj yeem ua rau tib qhov teeb meem.
Yog tias koj xav txwv qhov muaj peev xwm kis tau BPA: Siv lub khob iav zoo-nyab xeeb lossis tais diav kom sov cov zaub mov hauv lub microwave. Tsis txhob muab cov khoom kub lossis dej haus tso ncaj qha rau hauv cov thawv yas. Ntxuav cov khoom yas los ntawm txhais tes, nrog xab npum maj mam, dej sov, thiab txhuam tsis txhuam los yog khaub ncaws. Muab pov tseg khawb, tsis hloov xim, ploj mus, lossis plam plhaws plhaws, lossis cov yas ntim khoom noj uas tau siv rau lub sijhawm ntev
Kauj Ruam 3. Nrhiav lwm txoj yas rau cov khoom uas ua rau lub qhov ncauj tiv tauj
Tshwj xeeb tshaj yog yog tias koj muaj menyuam yaus nyob ib puag ncig, koj paub tias cov ntim khoom noj thiab dej haus tsis yog cov yas nkaus xwb uas ua rau lub qhov ncauj sib cuag. Kev nqus, zom, lossis - yog - nqos cov khoom yas zoo li txhuam hniav thiab cov khoom ua si tuaj yeem ua rau muaj BPA raug.
- Ib zaug ntxiv, kev txhawj xeeb pej xeem ntau ntxiv txog dab tsi tuaj yeem nyob hauv lawv cov yas tau ua rau rov tshwm sim ntawm cov khoom me nyuam, khoom ua si, thiab lwm yam khoom lag luam ua los ntawm cov khoom siv ib txwm, tsis yog yas. Tsis kho, cov ntoo uas tsis tau kho yog tsuas yog lom zem ntau li cov yas.
- Tshwj xeeb tshaj yog rau menyuam yaus, saib cov khoom ua si uas ua los ntawm ntoo tsis muaj txheej, paj rwb, ntaub plaub, thiab lwm yam. Tsis txhob cia koj tus menyuam yaus zom zaub hauv TV, xov tooj ntawm tes, thiab lwm yam.
Kauj Ruam 4. Txo kev txhawj xeeb ntau ntxiv txog kab noj hniav ntau dua li ua tau BPA hauv koj cov tshuaj txhuam hniav thiab cov khoom sib xyaw
BPA tsis tau siv ncaj qha rau hauv cov tshuaj txhuam hniav los yog cov khoom sib xyaw, tab sis nws tuaj yeem tshwm sim raws li cov khoom seem uas seem dhau los ntawm cov txheej txheem tsim khoom lossis tsim nyob rau hauv ib feeb los ntawm kev puas tsuaj ntawm lwm cov ntaub ntawv hauv cov foob. Txhua qhov pov thawj qhia tias ib qho kev kis BPA yuav yog ib ntus (feem ntau tsawg dua peb teev) thiab 50, 000 zaug qis dua qhov pib rau qhov tshwm sim tshwm sim sai.
Cov kab hauv qab, yam tsawg kawg nkaus kom deb li qhov kev tshawb fawb tam sim no qhia: Koj tuaj yeem pom zoo rau feeb me ntsis ntawm BPA rau ib ntus tom qab ua kev kho hniav tiav. Txawm li cas los xij, qhov kev pheej hmoo ntawm kev noj qab haus huv ntawm kev tawm kab noj hniav lossis lwm yam teeb meem kho hniav tsis tau kho yuav tsum muaj ntau dua kev txhawj xeeb txog kab BPA
Ntu 3 ntawm 3: Txheeb Xyuas Qhov Teeb Meem
Kauj Ruam 1. Kawm paub ntau ntxiv txog BPA
Tsis tau nkag mus rau kev kawm txog tshuaj lom neeg ntawm no, nws yog tej zaum txaus los hais tias bisphenol-A (BPA) yog cov khoom siv tshuaj lom neeg ntxiv. Nws ntxiv cov yoog raws lub zog rau ntau yam ntawm cov yas polycarbonate, ntxiv rau cov tshuaj epoxy hauv cov khoom xws li tuaj yeem ua cov txheej thiab cov tshuaj txhuam hniav.
Hmoov tsis zoo, thaum noj ntau txaus, BPA kuj tau pom tias yog "cov tshuaj cuam tshuam" uas ua rau cov tshuaj estrogen. Cov lus nug tiag tiag yog "BPA phem npaum li cas rau peb?", Thiab "Yuav tsum siv BPA ntau npaum li cas thiaj ua rau muaj kev phom sij?"
Kauj Ruam 2. Nyuaj rau ob sab ntawm kev sib cav txog BPA kev nyab xeeb
Tsoomfwv Meskas Cov Khoom Noj thiab Tshuaj (FDA) tau hais meej txog qhov teeb meem: "tam sim no pom zoo siv BPA hauv cov ntim khoom noj thiab ntim khoom muaj kev nyab xeeb." Thiab, tsuas yog kom pom meej ntxiv: “Puas yog BPA nyab xeeb? Yog.” Yeej, FDA (thiab cov tuam txhab tsim cov yas) sib cav tias thaum BPA tuaj yeem tsim teeb meem kev noj qab haus huv, qhov nyiaj koj tuaj yeem noj tau los ntawm cov khoom lag luam yog qis dua qhov pib rau kev txhawj xeeb.
- Cov neeg tawm tsam tiv thaiv BPA thiab qee tus kws tshawb fawb tsis paub meej txog qhov ntawd, txawm li cas los xij. Vim tias BPA ua raws li cov tshuaj estrogen, lawv thov, txawm tias tsawg dua tuaj yeem cuam tshuam rau lub hlwb, kev coj tus cwj pwm, thiab kev tsim menyuam yaus, tshwj xeeb tshaj yog hauv cev xeeb tub, menyuam mos, thiab menyuam yaus. Kev kis BPA kuj tseem tuaj yeem txuas rau kev rog thiab tej zaum tseem muaj qee yam mob qog noj ntshav.
- Yeej, cov neeg tawm tsam BPA tawm tsam, BPA tsis pom zoo los ntawm FDA vim tias nws tau raug pov thawj "nyab xeeb"; nws tau yooj yim "tsis tau pov thawj tsis nyab xeeb" rau qib uas txaus los ntseeg lub koom haum.
Kauj Ruam 3. Nug seb puas muaj cov yas uas tsis muaj BPA yuav tsum muaj kev nyab xeeb dua
Hauv kev teb rau cov neeg siv khoom siab, ntau lub tuam txhab yas tau maj nrawm tshem BPA los ntawm lawv cov khoom. Feem ntau, BPA tau hloov los ntawm bisphenol-S (BPS) lossis cov tshuaj zoo sib xws. Hmoov tsis zoo, muaj pov thawj ntau ntxiv tias BPS (thiab lwm yam tshuaj zoo sib xws) kuj tseem yuav ua rau muaj kev cuam tshuam zoo sib xws rau tib neeg lub cev li BPA.
- Ib txoj kev tshawb fawb ntawm 455 cov khoom yas tau pom tias yuav luag txhua ntawm lawv, suav nrog cov ntawv "BPA-free," muaj qee cov tshuaj estrogen-ua raws cov tshuaj hauv.
- Yeej, yog tias koj ntseeg tias koj yuav tsum muaj kev txhawj xeeb txog BPA thiab zam nws, koj yuav tsum tau sim txwv koj kev sib cuag nrog txhua yam yas (tshwj xeeb yog cov yas polycarbonate). Ib zaug ntxiv, kawm qhov teeb meem thiab txiav txim siab zoo tshaj plaws rau koj tus kheej thiab koj tsev neeg.
