Hmoov zoo vim cov neeg siv khoom tsis txaus siab, BPA tau raug tshem tawm los ntawm cov yas muag los siv ua lub raj mis dej thiab cov thawv ntim khoom noj. Tsuas yog tsib xyoos dhau los thaum kuv tus poj niam thiab kuv muaj peb tus menyuam thawj zaug (peb muaj menyuam ntxaib), nrhiav BPA-dawb lub raj mis yog qhov nyuaj thiab kim heev; Txij li thaum Lub Xya Hli 2012, txawm li cas los xij, FDA tau txwv tsis pub siv cov me nyuam lub raj mis thiab khob sippy.

Nov yog ob yam uas yuav tsum tsom ntsoov rau.

1. Ua ntse txog cov kaus poom. BPA yog txheej txheej sab hauv cov kaus poom. Zam cov zaub hauv kaus poom thiab xaiv cov tshiab lossis khov yuav tsum tsis txhob hloov pauv. Kev yuav taum qhuav es tsis txhob taum taum yuav tsis tsuas yog txo koj qhov raug rau BPA xwb, tab sis nws yog tus nqi ntau dua thiab nws ua rau tswj koj cov sodium kom tsawg dua. Thaum muas cov txiv lws suav, nrhiav cov muag hauv iav hub thaum twg los tau. Thaum muaj cov kaus poom dawb BPA rau taum, lawv tsis tshua muaj tshwm sim rau cov khoom lag luam lws suav, vim tias cov kua qaub ntawm cov txiv lws suav ua rau txheej txheej tiv thaiv BPA yog ib qho tseem ceeb tiv thaiv tiv thaiv cov hlau ntawm cov kaus poom.

2. Poob phaus. BPA yog cov tshuaj muaj roj-soluble uas tuaj yeem khaws cia hauv koj cov rog rog. Yog li thaum koj tuaj yeem ua qhov zoo tshaj plaws kom koj lub tsev BPA-dawb plua plav thaum tsis khaws koj cov zaub mov hauv cov yas uas muaj BPA, cov xov xwm phem yog qhov ntawd. koj tej zaum yuav yog lub nkoj loj tshaj plaws ntawm BPA hauv koj lub neej. Qhov xwm zoo yog tias koj lub cev tuaj yeem tso tawm BPA ntawm cov zis. Thaum koj tso nws los ntawm koj lub cev rog, koj lub cev tuaj yeem tshem tau nws. Kev poob phaus thiab nyob twj ywm ntshiv tuaj yeem yog ib txoj hauv kev zoo tshaj plaws los txo koj cov kev raug mob thiab kev txuam nrog BPA.
