Ungaphuzi amanzi avela emabhodleleni epulasitiki, ungadli ukudla okusemathinini, ungafaki ukudla okushisayo emabhokisini epulasitiki... Cishe usuzwile eziningi zalezi zindaba, akunjalo? Ngokuvamile, umlingiswa ofihliwe ngemuva kwazo zonke lezi zixwayiso yikhemikhali ebizwa ngokuthi i-BPA, noma i-Bisphenol A. Ingabe kufanele sikwesabe ngempela lokhu? Noma cha? Kunokukhulunywa okuningi ngakho. Ngakho-ke, ake sithole ukuthi kuyini ngempela namuhla.
Iyini ngempela i-BPA (i-Bisphenol A)?
Kalula nje, i-BPA iyikhemikhali esetshenziswa emafektri. Ibilokhu ikhona kusukela ngawo-1950. Uyazi ukuthi yenzelwe ini? Isetshenziswa kakhulu ekwenzeni amapulasitiki e-polycarbonate nama-epoxy resins. Lokhu yikho okwakha iningi lemikhiqizo yepulasitiki esiyisebenzisayo, ikakhulukazi leyo eqinile, esobala .
Cabanga ngakho, izinto ezifana namabhodlela amanzi owasebenzisayo, izitsha zokugcina ukudla zepulasitiki, kanye nezingxenye zokudla neziphuzo ezisemathinini kungase kube ne-BPA.
Esikhathini esithile esidlule, i-BPA yayisetshenziswa emikhiqizweni eminingi. Kodwa-ke, lapho kunengxoxo yomhlaba wonke mayelana nezingozi zayo zempilo, izinhlangano ezifana ne-FDA (Food and Drug Administration) e-United States, ikakhulukazi i-FDA, zacela izinkampani ezenza amabhodlela ezingane, izinkomishi zokusela, kanye namathini efomula yezingane ukuba ziyeke ukusebenzisa i-BPA. Ngakho-ke, imikhiqizo eminingi yezingane emakethe manje ayinayo i-BPA , okungukuthi, ayinayo i-BPA. Futhi, izinkampani eziningi ezenza amabhodlela amanzi nezitsha zokudla manje ziyekile ngokuzithandela ukusebenzisa i-BPA. Ngakho-ke, kunemikhiqizo embalwa kakhulu equkethe i-BPA emakhaya ethu manje kunaseminyakeni embalwa edlule. Kodwa-ke, i-BPA akuyona into evinjelwe ngokuphelele.
Yiziphi izindawo ezingaba ne-BPA?
I-BPA, ikhemikhali ebilokhu isetshenziswa ukuqinisa amapulasitiki iminyaka engaphezu kwengu-40, cishe ingatholakala ezindaweni eziningi ezisizungezile. Izifundo zibonisa ukuthi abangaphezu kuka-90% kithi kakade banenani elincane le-BPA emizimbeni yethu. Ingangena emizimbeni yethu hhayi ngezinto esizisebenzisayo kuphela, kodwa nangomoya, uthuli, namanzi.
Izinto ezivamile ezingase zibe ne-BPA zifaka:
- Amabhodlela amanzi epulasitiki
- Ulwelwesi lwangaphakathi lokudla neziphuzo ezisemathinini
- Izitsha zokugcina ukudla ezenziwe ngepulasitiki
- Amanye amadivayisi ezokwelapha
- Izinto zokuvala amazinyo
- Ama-compact disc (ama-CD)
Ochwepheshe bakhomba ukuthi nakuba ezinye izinkampani zingase zibize izitsha zazo ngokuthi “azinayo i-BPA,” empeleni kungenzeka ukuthi zisebenzisa amanye ama-bisphenol afana ne-BPA, njenge-BPS noma i-BPF. Kusenemibuzo mayelana nokuthi ziphephile kangakanani, ngakho-ke kuwukuhlakanipha ukusebenzisa izitsha zeglasi noma nini lapho kungenzeka.
Lezi zinto zingena kanjani emizimbeni yethu?
Indlela eyinhloko i-BPA engena ngayo emizimbeni yethu iwukudla neziphuzo esiziphuzayo. I-BPA ingatholakala ezintweni ezifana nokudla okusemathinini, amanzi asemabhodleleni epulasitiki, kanye namabhokisi okudla kwasemini e-polycarbonate, futhi ingangena ekudleni noma esiphuzweni esikuqukethe.
Into ebaluleke kakhulu izinga lokushisa . Uma ufaka into eshisayo esitsheni sepulasitiki, isibonelo, uma ubeka ilayisi oliletha ehhovisi ebhokisini lesidlo sasemini lepulasitiki lisashisa, kunethuba elikhulu lokuthi leli khemikhali lizoncibilika futhi lingene ekudleni. I-BPA ingadluliselwa enganeni ngobisi lwebele.
Ingabe i-BPA imbi ngempela empilweni yethu?
Abantu baqala ukukhathazeka ngalokhu ngemuva kokuba izifundo zezilwane zithole ukuthi ukuchayeka emazingeni aphezulu e-BPA kuhlotshaniswa nezimo ezifana nokuphuphuma kwesisu, isifo sikashukela, ukukhuluphala ngokweqile, isifo senhliziyo, kanye nomfutho wegazi ophakeme. Ezinye izifundo kubantu zithole nokuxhumana phakathi kwe-BPA nezifo ezithile. Kodwa-ke, akukafakazelwa ngokuqondile ukuthi i-BPA iyimbangela yalezo zifo. Okwamanje, kunezifundo eziphikisana nale miphumela.
Kodwa-ke, kusenempikiswano mayelana nemiphumela engaba khona ye-BPA emzimbeni. Ake sibheke ukuthi ziyini lezo zingozi.
| Ingozi engaba khona empilweni | Incazelo |
|---|---|
| Imiphumela emazingeni ama-hormone | Abanye ochwepheshe bakholelwa ukuthi i-BPA ingasebenza njenge-hormone emzimbeni, iphazamise amazinga ajwayelekile ama-hormone kanye nentuthuko, ikakhulukazi ezinsaneni, izinsana, kanye nezingane ezincane. Imiphumela evela ezifundweni zezilwane ixubile. |
| Izinkinga zobuchopho nokuziphatha | Uhlelo Lukazwelonke Lwezokwelapha Ubuthi lwe-FDA lugxile emiphumeleni engaba khona ye-BPA ebuchosheni nasekuziphatheni kwezingane. |
| Ingozi yomdlavuza | Ezinye izifundo zezilwane zibonise ukuxhumana phakathi kokuchayeka ku-BPA kanye nengozi eyengeziwe yomdlavuza kamuva ekuphileni. |
| Isifo senhliziyo | Izifundo ezimbili zithole ukuthi abantu abadala abanamazinga aphezulu e-BPA emizimbeni yabo banamathuba amaningi okuthola isifo senhliziyo. Kodwa akucaci ukuthi lokhu kuxhumana kubangelwa yi-BPA uqobo. |
| Ezinye izimo | Nakuba ucwaningo luye lwenziwa mayelana nokuxhumana phakathi kwezimo ezifana nokukhuluphala ngokweqile, isifo sikashukela, kanye ne-ADHD kanye ne-BPA, abukho ubufakazi obuqinile balokho. |
Ubani osengozini enkulu?
Izifundo eziningi zisikisela ukuthi izinsana nezingane ezincane zisengozini enkulu yokuthola imiphumela ye-BPA, ngoba imizimba yazo isakhula futhi ayikwazi ukuqeda izinto eziyingozi kunabantu abadala.
Yini esingayenza ukuze sizivikele ku-BPA?
Izifundo zisaqhubeka ngalokhu. Okwamanje, kunezinyathelo ezilula ongazithatha ukuze uhlale kude ne-BPA. Ngokulandela lezi, unganakekela impilo yakho neyomndeni wakho ngaphandle kokwesaba okungadingekile.
- Nciphisa ukusebenzisa kwakho ipulasitiki ngangokunokwenzeka. Kungase kungenzeki ukuqeda ipulasitiki ngokuphelele. Kodwa nciphisa ukusetshenziswa kwezitsha zepulasitiki, ikakhulukazi ekudleni okunamafutha (i-sambal, i-margarine, i-mayonnaise) kanye nokudla okushisayo.
- Sebenzisa izitsha zengilazi, ze-porcelain, noma zensimbi engagqwali. Lezi zifaneleka kakhulu ukugcina ukudla kanye nokudla noma iziphuzo ezishisayo.
- Ungafudumezi izitsha zepulasitiki. Ungafaki ama-microwave noma amabhokisi esidlo sasemini emshinini wokuwasha izitsha. Ukushisa kungaphula ipulasitiki ngokuhamba kwesikhathi futhi kukhulule i-BPA.
- Khetha imikhiqizo engenayo i-BPA. Amabhodlela amaningi ezingane, izinkomishi, neminye imikhiqizo manje inamagama athi "Akukho-BPA" abekwe ngokusobala.
- Nciphisa ukudla kwakho okusemathinini. Amathini amaningi angase abe ne-BPA ngaphakathi kwawo.
- Bheka ikhodi yokuvuselela kabusha epulasitikini. Uma kukhona unxantathu phansi kwesitsha sepulasitiki esinenombolo 3 noma 7 ngaphakathi, cishe izoba ne-BPA.
- Qaphela lapho ukhetha ifomula yezingane. Imikhiqizo eminingi manje isebenzisa amathini angenayo i-BPA. Uma kukhona ukungabaza ngokuthi ithini liqukethe i-BPA, abanye ochwepheshe bathi kungcono ukukhetha ifomula eyimpuphu kunobisi oluwuketshezi, njengoba uketshezi lunamathuba amaningi okumunca i-BPA.
Uma uneminye imibuzo mayelana nalokhu, sicela usithinte.Ungesabi ukukhuluma nodokotela. Uzokunikeza iseluleko esinembile kakhulu.
Umlayezo Wokuya Nawe Ekhaya
- I-BPA iyikhemikhali etholakala kwezinye izipulasitiki namathini.
- Imibono yesayensi ixubile ngemiphumela yayo emzimbeni womuntu, kodwa kubalulekile ukuqaphela, ikakhulukazi ngempilo yezingane ezincane.
- Asikho isidingo sokwesaba, kodwa unganciphisa ukuchayeka kwakho ku-BPA ngokulandela izinyathelo ezilula.
- Gwema ukufaka izinto ezishisayo ezitsheni zepulasitiki. Sebenzisa njalo izitsha zeglasi noma zensimbi engagqwali uma kungenzeka.
- Ukunciphisa ukudla kwakho okusemathinini kuyindlela enhle yokunciphisa ukuchayeka ku-BPA.
