Raws li cov neeg nyiam tsiaj, peb saib xyuas peb tus tsiaj kev nyab xeeb kom lawv tsis txhob muaj xwm txheej, pub zaub mov rau lawv noj thiab coj lawv mus rau tsiaj thaum lawv muaj mob. Tab sis dab tsi txog cov khoom ua si peb yuav rau peb cov dev - peb puas kub siab txog txaus txaus ntshai?

Dr. Rory Lubold, tus kws kho tsiaj nrog Paion Veterinary hauv Scottsdale, Arizona piav qhia tias "Cov khoom ua si yog ib feem tseem ceeb ntawm tus tsiaj lub neej. "Lawv tau ua cov cuab yeej txhawb nqa thiab qhov kev xav los ntawm kev xav los ua kom peb cov tsiaj tu thiab ua si." Tab sis vim tias cov yas thiab cov khoom siv tuaj yeem ua rau zais kev phom sij, nws qhia tias koj yuav tsum "saib xyuas koj cov tsiaj txhu tom qab muab cov khoom ua si tshiab rau nws."

Tsis zoo li menyuam cov khoom ua si menyuam yaus, tsis muaj lub cev uas tswj xyuas kev nyab xeeb ntawm cov menyuam dev. Thaddeus Harrington, tus kws tshaj lij ntawm tsoomfwv Meskas Consumer Product Safety Commission tau hais tias, "Cov khoom ua si tsiaj tsis poob rau hauv peb txoj cai," npaj siv.

Qhov ntawd txhais tau hais tias theus yog ntawm cov neeg siv khoom kom txheeb xyuas kev nyab xeeb los ntawm kev nyab xeeb, thiab nkag siab cov ntawv sau tuaj yeem tuaj yeem pab tau. Qee cov dev cov khoom ua si muaj cov ntawv cim xws li “BPA-free,” “phthalate-free” thiab “nontoxic,” tab sis rau cov neeg uas tsis muaj kev xav paub txog cov ntsiab lus, cov lus no yuav tsis meej pem. Yog li, dab tsi yuav tsum cov tsiaj cov niam txiv saib thaum yuav khoom ua si, thiab peb yuav tsum zam dab tsi?

BPA yog dab tsi?

Thawj kauj ruam kom nkag siab cov ntawv sau rau dev cov khoom ua si yog cim lub ntsiab lus. BPA yog luv rau bisphenol A, ib qho tshuaj siv rau hauv kev tsim cov pa roj carbon polycarbonate. Raws li Center Center for Disease Control (CDC), BPA pom muaj nyob txhua qhov chaw-los ntawm cov taub ntim hauv cov dej haus thiab cov zaub mov tuaj yeem txuas mus rau cov tsheb. Ob qho tib si tib neeg thiab tsiaj txhu cuam tshuam nrog nws los ntawm cov khoom noj thiab dej haus.

Cov Phthalates Yog Dab Tsi?

Lo lus "phthalates" yog hais txog ib pawg tshuaj lom neeg kuj hu ua "yas," uas CDC piav qhia ua cov yas hloov tau yooj yim. Cov no muaj nyob hauv ntau lub hnab yas ntim khoom, cov khoom ua si rau menyuam yaus thiab tsiaj, thiab lub thawv ntim khoom.

Ib yam li BPA, kev cuam tshuam rau phthalates tsuas yog los ntawm cov zaub mov thiab dej haus uas tau khaws cia hauv cov thawv yas, lossis los ntawm cov khoom ua si uas muab tso rau hauv lub qhov ncauj. Cov ntawv lo uas nyeem “BPA-free” lossis “phthalate-free” txhais tau tias lub tuam txhab tau sim nws cov ntaub ntawv kom ntseeg tau tias lawv tsis muaj cov tshuaj lom no.

Raws li Harrington piav qhia, dev cov khoom ua si tsis yog tswj hwm los ntawm tsoomfwv, txhais tau tias tsis muaj txoj cai txwv kom cov tuam txhab sim cov khoom ua si lossis ua raws li tus qauv (tsis zoo li menyuam cov khoom ua si). Qee lub tuam txhab yuav rov ua lawv cov ntaub ntawv nrog cov ntaub ntawv hais txog kev sim hauv lawv lub vev xaib, tab sis lwm qhov tsis muaj ntaub ntawv ntau heev. Thaum daim ntawv lo qhia tias lawv tau ua qhov kev sim, qhov kev twv zoo tshaj plaws rau cov niam txiv yog tiv tauj lub tuam txhab ncaj qha.

Dab Tsi Tsis Nontoxic?

Tseem tab tom xav tias daim ntawv “tsis zoo” txhais tau li cas? Uas ib tug yog trickier. Raws li ib puag ncig ua hauj lwm ib puag ncig, "Lub ntsiab lus lag luam no txhais tau tias cov khoom lag luam lossis cov khoom yuav tsis ua mob rau tib neeg kev noj qab haus huv lossis ib puag ncig."

Muaj Peev Xwm Teeb ntawm BPA thiab Phthalates

Kev phom sij ntawm BPA thiab phthalates tseem muaj ntau qhov tsis paub, tab sis ib qho yog qhov tseeb: cov tshuaj lom neeg no muaj ntau qhov nyob ib puag ncig thiab peb lub cev. Raws li National Institute for Environmental Health Sciences tau tshawb fawb, Xyoo 2003-2004 Kev Tshuaj Ntsuam Xyuas Kev Noj Qab Haus Huv thiab Khoom Noj Hauv Tebchaws (NHANES III) tshawb pom los ntawm CDC pom cov qib BPA nyob rau hauv 93 feem pua ntawm 2, 517 cov zis ntsuas ntawm tib neeg 6 xyoo thiab laus dua.”

BPA tau dhau los ua kev txhawj xeeb rau pej xeem hauv xyoo tsis ntev los no vim muaj ntau cov kev tshawb fawb uas pom tias cov tshuaj ua "ua rau muaj kev cuam tshuam" endocrine, "txhais tau tias nws tuaj yeem hloov cov tshuaj hormones. Cov kev tshawb fawb no tau txuas BPA nrog cov teeb meem kev muaj me nyuam hauv cov nas (uas muaj qhov cuam tshuam rau tib neeg kev muaj me nyuam) thiab hloov cov thyroid hormone ntau ntau hauv cov poj niam cev xeeb tub. Zoo sib xws, cov kev tshawb fawb tsis ntev los no txog phthalate tau qhia tias nws yuav muaj kev cuam tshuam rau menyuam txoj kev loj hlob lossis tseem muaj kev pheej hmoo mob ntshav qab zib hauv tib neeg.

Txawm hais tias tsis tshua muaj kev tshawb fawb txog kev cuam tshuam ntawm cov tshuaj no rau cov tsiaj hauv tsev, kev tshawb nrhiav xyoo 2013 tau qhia tias cov khoom lag luam rau kev zom thiab qog los ntawm dev feem ntau muaj BPA thiab phthalates, uas tuaj yeem, qee kis, thiav tawm ntawm cov yas thiab mus rau hauv cov dev cov qaub ncaug Cov.

Ib qho kev tshawb pom ntau dua uas tau ua rau xyoo tas los no qhia tias BPA hauv cov dev hauv kaus poom tseem muaj kev cuam tshuam ntawm cov tsiaj cov tsiaj BPA, qhia kev hloov pauv mus rau lawv lub plab microbiome. Dr. Lubold tau hais tias "Tus naj npawb ntawm BPA hauv cov khoom noj dev hauv kaus poom muaj ntau dua qhov nyiaj hauv cov khoom ua si," Dr. Lubold tau hais tias, "Tsis muaj ntau cov ntaub ntawv hais txog kev txhawj xeeb txog kev noj qab haus huv nrog BPA thiab phthalates lossis lwm yam tshuaj lom thaum hais txog lawv suav nrog cov khoom ua si."

Vim tias tseem muaj ntau yam heev uas peb tsis paub txog cov tshuaj no, nws yog qhov zoo tshaj rau sab nyab xeeb. Dr. Lubold hais tias "Raws li txoj cai dav dav, nws yuav zoo kom tsis txhob muaj cov tshuaj ntxiv thiab cov yas ua kua thaum ua tau," tab sis nws sau tseg tias qhov yuav ua rau cov tsiaj muaj mob tuaj ntawm cov tshuaj no tsawg tsawg.

Nws hais tias, "Feem ntau cov dev yuav zom cov khoom ua si qee zaus thiab tsis noj tshuaj lom neeg kom txaus rau qhov tseem ceeb," nws hais. "Txawm li cas los xij, cov tshuaj siv tau tuaj yeem qog cov estrogens thiab muaj kev cuam tshuam rau ib puag ncig mus txog ib puag ncig."
