Musa ukusela amanzi kwiibhotile zeplastiki, musa ukutya ukutya okusemathinini, musa ukufaka ukutya okushushu kwiibhokisi zesidlo sasemini zeplastiki... Mhlawumbi ukhe weva la mabali amaninzi, akunjalo? Rhoqo, umlinganiswa ofihlakeleyo emva kwazo zonke ezi zilumkiso yikhemikhali ebizwa ngokuba yiBPA, okanye iBisphenol A. Ngaba simele soyike oku ngokwenene? Okanye akunjalo? Kukho intetho eninzi ngayo. Ngoko ke, masifumanise ukuba yintoni kanye kanye namhlanje.
Yintoni kanye kanye iBPA (iBisphenol A)?
Ngamafutshane, i-BPA yikhemikhali esetyenziswa kwiifektri. Ibikho ukususela ngeminyaka yoo-1950. Uyazi ukuba yenzelwe ntoni? Isetyenziswa kakhulu ekwenzeni iiplastiki ze-polycarbonate kunye nee-epoxy resins. Ezi zezona zinto zenza uninzi lweemveliso zeplastiki esizisebenzisayo, ingakumbi ezomeleleyo nezicacileyo .
Cinga ngako, izinto ezifana neebhotile zamanzi ozisebenzisayo, izikhongozeli zokugcina ukutya zeplastiki, kunye nemigca yokutya okusemathinini kunye neziselo zinokuba ne-BPA.
Kudala, i-BPA yayisetyenziswa kwiimveliso ezininzi. Nangona kunjalo, xa kwakukho ingxoxo kwihlabathi liphela malunga neengozi zayo zempilo, imibutho efana ne-FDA (Food and Drug Administration) e-United States, ingakumbi i-FDA, yacela iinkampani ezenza iibhotile zeentsana, iikomityi zokusela, kunye neetini zefomyula zeentsana ukuba ziyeke ukusebenzisa i-BPA. Ke ngoko, iimveliso ezininzi zeentsana ezikwimarike ngoku azina-BPA , oko kukuthi, azina-BPA. Kwakhona, iinkampani ezininzi ezenza iibhotile zamanzi kunye nezikhongozeli zokutya ngoku ziye zayeka ngokuzithandela ukusebenzisa i-BPA. Ke ngoko, zimbalwa kakhulu iimveliso ezine-BPA emakhayeni ethu ngoku kunakwiminyaka embalwa eyadlulayo. Nangona kunjalo, i-BPA ayisiyonto ivaliweyo ngokupheleleyo.
Zeziphi iindawo ezinokuba ne-BPA?
I-BPA, ikhemikhali ebisoloko isetyenziswa ukuqinisa iiplastiki kangangeminyaka engaphezu kwama-40, ifumaneka kwiindawo ezininzi ezisingqongileyo. Izifundo zibonisa ukuba ngaphezu kwama-90% ethu sele enayo i-BPA encinci emizimbeni yethu. Ingangena emizimbeni yethu kungekuphela nje ngezinto esizisebenzisayo, kodwa nangomoya, uthuli, namanzi.
Izinto eziqhelekileyo ezinokuba ne-BPA ziquka:
- Iibhotile zamanzi zeplastiki
- Ulwelo lwangaphakathi lokutya okusemathinini kunye neziselo
- Izikhongozeli zokugcina ukutya ezenziwe ngeplastiki
- Ezinye izixhobo zonyango
- Izinto zokuvala amazinyo
- Iidiski ezimfutshane (iiCD)
Iingcali zithi nangona ezinye iinkampani zinokubiza izikhongozeli zazo ngokuthi "azina-BPA," kusenokwenzeka ukuba zisebenzisa ezinye ii-bisphenols ezifana ne-BPA, ezifana ne-BPS okanye i-BPF. Kusekho imibuzo malunga nokuba zikhuselekile kangakanani, ngoko ke kububulumko ukusebenzisa izikhongozeli zeglasi nanini na xa kunokwenzeka.
Ezi zinto zingena njani emizimbeni yethu?
Eyona ndlela iphambili i-BPA engena ngayo emizimbeni yethu kukutya neziselo esiziselayo. I-BPA inokufumaneka kwizinto ezifana nokutya okusemathinini, amanzi afakwe ebhotileni yeplastiki, kunye neebhokisi zesidlo sasemini ze-polycarbonate, kwaye inokungena ekutyeni okanye kwisiselo esikuyo.
Eyona nto ibalulekileyo bubushushu . Xa ubeka into eshushu kwisikhongozeli seplastiki, umzekelo, xa ubeka irayisi oyizisa eofisini kwibhokisi yesidlo sasemini yeplastiki ngelixa isashushu, kukho ithuba elikhulu lokuba le khemikhali iya kunyibilika ize ingene ekutyeni. I-BPA inokudluliselwa kumntwana ngobisi lwebele.
Ngaba i-BPA imbi ngokwenene kwimpilo yethu?
Abantu baqala ukuxhalaba ngale nto emva kokuba izifundo zezilwanyana zifumanise ukuba ukuchanabeka kumanqanaba aphezulu e-BPA kunxulunyaniswa neemeko ezifana nokuphuphuma kwesisu, isifo seswekile, ukutyeba kakhulu, isifo sentliziyo, kunye noxinzelelo lwegazi oluphezulu. Ezinye izifundo ebantwini zikwafumene unxibelelwano phakathi kwe-BPA kunye nezifo ezithile. Nangona kunjalo, akuqinisekiswanga ngokuthe ngqo ukuba i-BPA yimbangela yezo zifo. Okwangoku, kukho izifundo eziphikisana nezi ziphumo.
Nangona kunjalo, kusekho ingxoxo malunga nemiphumo enokubakho ye-BPA emzimbeni. Makhe sijonge ukuba zeziphi ezo ngozi.
| Umngcipheko onokwenzeka kwimpilo | Inkcazo |
|---|---|
| Iziphumo kumanqanaba e-hormone | Ezinye iingcali zikholelwa ukuba i-BPA inokusebenza njengehomoni emzimbeni, iphazamise amanqanaba aqhelekileyo ehomoni kunye nophuhliso, ingakumbi kwiintsana ezisandul’ ukuzalwa, iintsana, kunye nabantwana abancinci. Iziphumo ezivela kwizifundo zezilwanyana ziyaxubana. |
| Iingxaki zobuchopho kunye nokuziphatha | Inkqubo yeSizwe ye-FDA yeToxicology igxile kwimiphumo enokubakho ye-BPA kwiingqondo nakwindlela yokuziphatha yabantwana. |
| Umngcipheko womhlaza | Ezinye izifundo zezilwanyana zibonise unxibelelwano phakathi kokuchatshazelwa yi-BPA kunye nomngcipheko okhulayo womhlaza kamva ebomini. |
| Isifo sentliziyo | Izifundo ezimbini zifumanise ukuba abantu abadala abanamanqanaba aphezulu e-BPA emizimbeni yabo banamathuba amaninzi okufumana isifo sentliziyo. Kodwa akucaci nokuba olu nxibelelwano lubangelwa yi-BPA ngokwayo. |
| Ezinye iimeko | Nangona uphando lwenziwe malunga nonxibelelwano phakathi kwe-BPA kunye neemeko ezifana nokutyeba kakhulu, isifo seswekile, kunye ne-ADHD, akukho bungqina buqinileyo boku. |
Ngubani osengozini enkulu?
Izifundo ezininzi zibonisa ukuba iintsana nabantwana abancinci basengozini enkulu yeziphumo ze-BPA, kuba imizimba yabo isakhula kwaye ayikwazi ukukhupha izinto eziyingozi kunabantu abadala.
Singenza ntoni ukuze sizikhusele kwi-BPA?
Izifundo zisaqhubeka ngale nto. Okwangoku, kukho amanyathelo alula onokuwathatha ukuze uhlale kude ne-BPA. Ngokulandela la manyathelo, unokunyamekela impilo yakho neyentsapho yakho ngaphandle koloyiko olungeyomfuneko.
- Nciphisa ukusebenzisa kwakho iplastiki kangangoko unako. Kusenokungabi lula ukuyisusa ngokupheleleyo iplastiki. Kodwa nciphisa ukusetyenziswa kwezikhongozeli zeplastiki, ingakumbi ukutya okunamafutha (isambal, imargarine, imayonnaise) kunye nokutya okushushu.
- Sebenzisa izikhongozeli zeglasi, zeporcelain, okanye zentsimbi engagqwaliyo. Ezi zilungele ngokukodwa ukugcina ukutya kunye nokutya okushushu okanye iziselo.
- Musa ukufudumeza izikhongozeli zeplastiki. Musa ukufaka ii-microwave okanye iibhokisi zesidlo sasemini zeplastiki kwisitya sokuhlamba izitya. Ubushushu bunokwaphula iplastiki ngokuhamba kwexesha bukhuphe i-BPA.
- Khetha iimveliso ezingenayo i-BPA. Iibhotile ezininzi zabantwana, iikomityi, kunye nezinye iimveliso ngoku zinamagama athi "Akukho BPA" abekwe ngokucacileyo.
- Nciphisa ukutya okusemathinini. Iitini ezininzi zinokuba ne-BPA ngaphakathi.
- Jonga ikhowudi yokusetyenziswa kwakhona kweplastiki. Ukuba kukho unxantathu ezantsi kwesikhongozeli seplastiki esinenombolo 3 okanye 7 ngaphakathi, kusenokwenzeka ukuba iqulethe i-BPA.
- Lumka xa ukhetha ubisi lweentsana. Iinkampani ezininzi ngoku zisebenzisa iitini ezingenayo i-BPA. Ukuba kukho amathandabuzo okuba ubisi lweentsana lune-BPA, ezinye iingcali zithi kungcono ukhethe ubisi lweentsana oluyimpuphu kunobisi oluyimpuphu, kuba ulwelo lunamathuba amaninzi okufunxa i-BPA.
Ukuba unemibuzo engaphezulu malunga noku, nceda unxibelelane nathi.Ungoyiki ukuthetha nogqirha. Uza kukunika icebiso elichanekileyo.
Umyalezo Wokuya Ekhaya
- I-BPA yikhemikhali efumaneka kwiiplastiki nakwiitoti ezithile.
- Iimbono zesayensi zixubene malunga nemiphumo yayo emzimbeni womntu, kodwa kubalulekile ukuba silumke, ingakumbi kwimpilo yabantwana abancinci.
- Akukho mfuneko yokuba woyike, kodwa unganciphisa ukuvezwa kwakho kwi-BPA ngokulandela amanyathelo alula.
- Kuphephe ukufaka izinto ezishushu kwizikhongozeli zeplastiki. Sebenzisa izikhongozeli zeglasi okanye zentsimbi engagqwaliyo ukuba kunokwenzeka.
- Ukunciphisa ukutya okusemathinini kukwayindlela elungileyo yokunciphisa ukuvezwa yi-BPA.
