Txawm li cas los xij, muaj kev sib cav tsis tu ncua thiab kev txhawj xeeb txog cov txiaj ntsig kev noj qab haus huv ntawm plasticizers. Tsab ntawv xov xwm no yog lub hom phiaj los tshawb txog lub ntsiab lus los ntawm kev muab kev txheeb xyuas qhov tob ntawm ntau hom plasticizers, lawv cov ntawv thov, thiab cov kev pheej hmoo uas lawv yuav ua rau tib neeg noj qab haus huv.
Hom Plasticizers:
1. Phthalate-Based Plasticizers:
- Phthalate-based plasticizers tau siv dav rau ntau xyoo lawm. Lawv txhim kho qhov yooj thiab softness ntawm cov yas, ua rau lawv haum rau ntau yam kev siv.
- Feem ntau phthalate-based plasticizers suav nrog diethyl phthalate (DEP), dimethyl phthalate (DMP), thiab dibutyl phthalate (DBP).
- Cov plasticizers no tau raug tshuaj xyuas vim lawv muaj peev xwm cuam tshuam rau tib neeg kev noj qab haus huv.
2. Non-Phthalate Plasticizers:
- Hauv xyoo tas los no, tau muaj kev hloov pauv mus rau cov khoom siv tsis yog phthalate hauv cov lus teb rau kev txhawj xeeb ib puag ncig kev siv phthalates.
- Non-phthalate plasticizers, xws li adipates, esters, thiab citrates, muab lwm txoj hauv kev uas muaj feem cuam tshuam txog kev noj qab haus huv tsawg dua.
- Cov plasticizers no tau dhau los ua neeg nyiam hauv kev lag luam uas xav tau kev nyab xeeb dua.
Kev siv ntawm Plasticizers:
1. Khoom siv:
- Plasticizers feem ntau yog siv los tsim cov kav dej PVC, flooring, thiab cables. Lawv muab tau yooj yim thiab durability, ua rau cov ntaub ntawv no tiv taus ntau yam mob.
- Yog tsis muaj plasticizers, cov kav dej PVC yuav nruj thiab ua rau tawg, txwv tsis pub lawv siv tau hauv kev tsim kho.
2. Automotive Kev Lag Luam:
- Plasticizers ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv tsheb, xws li dashboard npog, lub rooj zaum npog, thiab lub kauj tsheb.
- Lawv txhim kho qhov hloov pauv ntawm cov khoom no, ua rau lawv tiv taus kev cuam tshuam thiab txhim kho kev nyab xeeb tag nrho.
3. Cov Khoom Siv Kho Mob:
- Plasticizers yog siv dav hauv kev tsim khoom siv kho mob, xws li IV hnab, catheters, thiab cov ntshav hloov ntshav.
- Cov khoom siv no xav tau kev hloov pauv yooj yim, thiab cov khoom siv yas kom ntseeg tau tias cov ntaub ntawv siv tau tuaj yeem tiv taus kev khoov thiab kev tswj tsis tau tawg.
Muaj peev xwm noj qab haus huv:
1. Kev cuam tshuam ntawm endocrine:
- Ib qho ntawm cov kev txhawj xeeb tseem ceeb cuam tshuam nrog cov yas yas, tshwj xeeb tshaj yog cov phthalate-based, yog lawv lub peev xwm los cuam tshuam cov kab mob endocrine.
- Cov kev tshawb fawb tsiaj tau pom tias qee cov phthalates tuaj yeem cuam tshuam nrog kev tsim cov tshuaj hormones thiab kev ua haujlwm, ua rau muaj kev cuam tshuam kev loj hlob thiab kev loj hlob.
2. Asthma thiab Allergies:
- Qee qhov kev tshawb fawb qhia txog qhov sib txuas ntawm qhov raug rau qee cov yas yas, xws li phthalates, thiab muaj kev pheej hmoo ntau ntxiv ntawm kev mob hawb pob thiab kev ua xua.
- Txawm li cas los xij, kev tshawb fawb ntxiv yog xav tau los tsim kom muaj kev sib txuas ntawm cov yas yas thiab cov kev mob nkeeg no hauv tib neeg.
3. Carcinogenicity:
- Qee cov khoom siv yas, xws li phthalates xws li diethylhexyl phthalate (DEHP), tau raug cais ua cov kab mob carcinogens los ntawm cov koom haum tswj hwm.
- Ntev ntev raug rau cov qib siab ntawm cov yas yas no tau pom muaj kev cuam tshuam tsis zoo hauv kev tshawb fawb tsiaj, ua rau muaj kev txhawj xeeb txog lawv cov peev xwm carcinogenicity hauv tib neeg.
4. Kev tsiv teb tsaws chaw rau zaub mov:
- Plasticizers tuaj yeem txav los ntawm cov khoom ntim khoom noj rau hauv cov zaub mov nws tus kheej, tshwj xeeb tshaj yog thaum raug tshav kub lossis acidic.
- Qhov no ua rau muaj kev txhawj xeeb vim qee cov plasticizers tuaj yeem tsim kev puas tsuaj thaum noj lossis nqus los ntawm lub cev.
Kev tswj hwm kev ntsuas thiab kev nyab xeeb ntawm cov neeg siv khoom:
1. Phthalate Bans:
- Ntau lub koom haum tswj hwm, xws li US Consumer Product Safety Commission (CPSC) thiab European Union, tau qhia txog kev txwv kev siv qee yam phthalates hauv cov neeg siv khoom.
- Cov kev txwv no txhawm rau txo qis qhov cuam tshuam rau cov khoom siv phom sij, tshwj xeeb yog siv hauv cov khoom ua si menyuam yaus thiab cov khoom tu menyuam yaus.
2. Lwm yam kev nyab xeeb:
- Kev txhim kho thiab siv cov yas yas uas tsis yog phthalate tau nce traction nyob rau xyoo tas los no raws li cov lus teb rau kev noj qab haus huv cuam tshuam nrog cov tshuaj yas yas.
- Cov kev xaiv no muab cov yam ntxwv zoo sib xws thaum txo cov kev pheej hmoo ntawm kev noj qab haus huv tsawg.
3. Consumer Awareness and Choices:
- Kev cob qhia cov neeg siv khoom txog cov kev pheej hmoo thiab cov txiaj ntsig ntawm cov yas yas yog qhov tseem ceeb rau kev txiav txim siab xaiv.
