Usanwe mvura inobva mumabhodhoro epurasitiki, usadye chikafu chemumagaba, usaise chikafu chinopisa mumabhokisi epurasitiki ekudya kwemasikati... Pamwe wakanzwa nyaya dzakawanda idzi, handiti? Kazhinji, hunhu hwakavanzika huri shure kweyambiro idzi ikemikari inonzi BPA, kana kuti Bisphenol A. Tinofanira kutya izvi zvechokwadi here? Kana kuti kwete? Pane zvakawanda zvinotaurwa nezvazvo. Saka, ngationei kuti chii chaizvo nhasi.
Chii chinonzi BPA (Bisphenol A) chaizvo?
Zvichitaurwa zviri nyore, BPA ikemikari inoshandiswa mumafekitori. Yagara iripo kubvira kuma1950. Unoziva here kuti inoshandisirwei? Inonyanya kushandiswa kugadzira mapurasitiki epolycarbonate uye epoxy resins. Izvi ndizvo zvinoumba zvigadzirwa zvepurasitiki zvakawanda zvatinoshandisa, kunyanya izvo zvakasimba, zvinoonekera .
Funga nezvazvo, zvinhu zvakaita semabhodhoro emvura aunoshandisa, midziyo yepurasitiki yekuchengetera chikafu, uye jira rezvimwe zvekudya nezvinwiwa zvemumagaba zvinogona kunge zvine BPA.
Kare kare, BPA yaishandiswa muzvigadzirwa zvakawanda. Zvisinei, pakava nehurukuro pasi rose nezvenjodzi dzayo dzehutano, masangano akadai seFDA (Food and Drug Administration) muUnited States, kunyanya FDA, akakumbira makambani anogadzira mabhodhoro evana, makapu anonwiwa, uye magaba emukaka wevana kuti arege kushandisa BPA. Nokudaro, zvigadzirwa zvakawanda zvevana zviri pamusika ikozvino hazvina BPA , kureva kuti, hazvina BPA. Zvakare, makambani mazhinji anogadzira mabhodhoro emvura nemidziyo yechikafu ikozvino arega kushandisa BPA nekuzvidira. Saka, kune zvigadzirwa zvishoma zvine BPA mudzimba dzedu ikozvino kupfuura zvaivepo makumi emakore apfuura. Zvisinei, BPA haisi chinhu chakarambidzwa zvachose.
Ndedzipi nzvimbo dzingangove neBPA?
BPA, kemikari yave ichishandiswa kusimbisa mapurasitiki kwemakore anopfuura makumi mana, ingangowanikwa munzvimbo dzakawanda dzakatipoteredza. Zvidzidzo zvinoratidza kuti vanopfuura 90% vedu tatova nehuwandu hushoma hweBPA mumiviri yedu. Inogona kupinda mumiviri yedu kwete chete kuburikidza nezvinhu zvatinoshandisa, asiwo kuburikidza nemhepo, guruva, nemvura.
Zvinhu zvakajairika zvinogona kunge zvine BPA zvinosanganisira:
- Mamwe mabhodhoro emvura epurasitiki
- Mucheka wemukati wezvikafu nezvinwiwa zvemumagaba
- Matangi ekuchengetera chikafu akagadzirwa nepurasitiki
- Mimwe michina yekurapa
- Zvivharo zvemazino
- MaCD (maCD)
Nyanzvi dzinoti kunyange hazvo mamwe makambani angati magaba avo "haana BPA," anogona kunge achishandisa mamwe ma bisphenols akafanana neBPA, akadai seBPS kana BPF. Pachine mibvunzo yekuti akachengeteka sei, saka kuchenjera kushandisa magaba egirazi pese pazvinogoneka.
Zvinhu izvi zvinopinda sei mumiviri yedu?
Nzira huru iyo BPA inopinda nayo mumiviri yedu ndeyekudya nezvinwiwa zvatinonwa. BPA inogona kuwanikwa muzvinhu zvakaita sechikafu chemumagaba, mvura yepurasitiki yakaputirwa mumabhodhoro, uye mumabhokisi ekudya epolycarbonate, uye inogona kupinda muchikafu kana chinwiwa chirimo.
Chinhu chinonyanya kukosha kupisa . Kana ukaisa chimwe chinhu chinopisa mupurasitiki, semuenzaniso, kana ukaisa mupunga waunouya nawo kuhofisi mubhokisi repurasitiki rekudya kwemasikati richiri kupisa, pane mukana mukuru wekuti kemikari iyi inyungudike yopinda muchikafu. BPA inogonawo kutapuriranwa kumwana kuburikidza nemukaka wemuzamu.
BPA yakaipa zvechokwadi pahutano hwedu here?
Vanhu vakatanga kunetseka nezveizvi mushure mekunge ongororo dzemhuka dzaona kuti kuwanda kweBPA kwakabatana nemamiriro ezvinhu akadai sekubuda kwepamuviri, chirwere cheshuga, kufuta, chirwere chemwoyo, uye BP. Zvimwe zvidzidzo muvanhu zvakawanawo hukama pakati peBPA nezvimwe zvirwere. Zvisinei, hazvina kuratidzwa zvakananga kuti BPA ndiyo inokonzera zvirwere izvozvo. Panguva iyi, kune zvidzidzo zvinopesana nemigumisiro iyi.
Zvisinei, kuchine gakava pamusoro pemigumisiro inogona kuitika yeBPA mumuviri. Ngatitarisei njodzi idzodzo.
| Njodzi inogona kuitika pahutano | Tsananguro |
|---|---|
| Mhedzisiro pamazinga emahormone | Dzimwe nyanzvi dzinofunga kuti BPA inogona kushanda sehomoni mumuviri, zvichikanganisa huwandu hwemahomoni akajairwa uye kukura, kunyanya muvana vachiri mudumbu, vacheche, nevana vadiki. Mhedzisiro yezvidzidzo zvemhuka yakasiyana. |
| Matambudziko ehuropi nemaitiro | Chirongwa cheNational Toxicology cheFDA chakanyanya kutarisa pamigumisiro inogona kuitika yeBPA papfungwa dzevana nemaitiro avo. |
| Njodzi yekenza | Dzimwe ongororo dzemhuka dzakaratidza hukama huripo pakati pekusangana neBPA nenjodzi yakawedzera yekenza gare gare muhupenyu. |
| Chirwere chemwoyo | Zvidzidzo zviviri zvakaratidza kuti vanhu vakuru vane BPA yakawanda mumuviri wavo vane mukana mukuru wekuwana chirwere chemwoyo. Asi hazvizivikanwe kana kubatana uku kuri kukonzerwa neBPA pachayo. |
| Mamwe mamiriro ezvinhu | Kunyangwe tsvakiridzo yakaitwa pakutsvaga hukama huripo pakati peBPA nematambudziko akadai sekufutisa, chirwere cheshuga, uye ADHD, hapasati pave neuchapupu hwakasimba hweizvi. |
Ndiani ari panjodzi huru?
Ongororo dzakawanda dzinoratidza kuti vacheche nevana vadiki ndivo vanonyanya kukanganiswa neBPA, nekuti miviri yavo ichiri kukura uye haigone kubvisa zvinhu zvinokuvadza kupfuura vanhu vakuru.
Chii chatingaita kuti tizvidzivirire kubva kuBPA?
Zvidzidzo zvichiri kuenderera mberi panyaya iyi. Panguva ino, kune matanho ari nyore aunogona kutora kuti usashandise BPA. Nekutevera aya, unogona kutarisira hutano hwako nehwemhuri yako pasina kutya kusingakoshi.
- Deredza kushandisa kwako mapurasitiki zvakanyanya sezvinobvira. Zvingasakwanisika kubvisa mapurasitiki zvachose. Asi deredza kushandisa mapurasitiki, kunyanya pakudya zvine mafuta (sambal, margarine, mayonnaise) uye zvekudya zvinopisa.
- Shandisa midziyo yegirazi, porcelain, kana simbi isina ngura. Izvi zvinonyanya kukodzera kuchengetera chikafu uye zvekudya kana zvinwiwa zvinopisa.
- Musapisa midziyo yepurasitiki. Musaisa ma microwave kana mabhokisi epurasitiki ekudya kwemasikati mudhishi rekugezesa ndiro. Kupisa kunogona kupwanya purasitiki nekufamba kwenguva uye kuburitsa BPA.
- Sarudza zvigadzirwa zvisina BPA. Mabhodhoro mazhinji evana, makapu, nezvimwe zvigadzirwa zvino zvave nemashoko ekuti "BPA-Free" akanyorwa pachena.
- Deredza kudya kwako chikafu chakabikwa mugaba. Magaba mazhinji anogona kunge aine BPA mukati mawo.
- Tarisa kodhi yekudzokorodza papurasitiki. Kana paine katatu pasi pemudziyo wepurasitiki ine nhamba 3 kana 7 mukati, kanowanzova neBPA.
- Chenjerera pakusarudza mukaka wevana. Makambani mazhinji ikozvino anoshandisa magaba asina BPA. Kana paine kusava nechokwadi chekuti kani rine BPA, dzimwe nyanzvi dzinoti zviri nani kusarudza mukaka weupfu pane mukaka wemvura, sezvo zvinwiwa zvichinyanya kupinza BPA.
Kana muine mimwe mibvunzo nezveizvi, ndapota taurai nesu.Usatya kutaura nachiremba. Achakupa mazano akanyatsonaka.
Mharidzo Yekuenda Nayo Kumba
- BPA ikemikari inowanikwa mune mamwe mapurasitiki nemakani.
- Mafungiro esainzi akasiyana-siyana nezvemigumisiro yayo pamuviri wemunhu, asi zvakakosha kungwarira, kunyanya nezvehutano hwevana vadiki.
- Hapana chikonzero chekuvhunduka, asi unogona kuderedza kubatwa neBPA nekutevera matanho ari nyore.
- Dzivisa kuisa zvinhu zvinopisa mumidziyo yepurasitiki. Shandisa midziyo yegirazi kana yesimbi isina ngura kana zvichibvira.
- Kuderedza kudya kwako chikafu chakabikwa mugaba inzira yakanaka yekuderedza kubatwa neBPA.
