Musamwe madzi ochokera m'mabotolo apulasitiki, musadye chakudya cha m'zitini, musaike chakudya chotentha m'mabokosi apulasitiki... Mwina mwamvapo nkhani zambiri izi, eti? Nthawi zambiri, munthu wobisika kumbuyo kwa machenjezo onsewa ndi mankhwala otchedwa BPA, kapena Bisphenol A. Kodi tiyenera kuopadi izi? Kapena ayi? Pali nkhani zambiri zokhudza izi. Choncho, tiyeni tidziwe bwino lomwe kuti ndi chiyani masiku ano.
Kodi BPA (Bisphenol A) ndi chiyani kwenikweni?
Mwachidule, BPA ndi mankhwala omwe amagwiritsidwa ntchito m'mafakitale. Yakhalapo kuyambira m'ma 1950. Kodi mukudziwa kuti imagwiritsidwa ntchito chiyani? Imagwiritsidwa ntchito kwambiri popanga mapulasitiki a polycarbonate ndi ma epoxy resins. Izi ndi zomwe zimapanga zinthu zambiri zapulasitiki zomwe timagwiritsa ntchito, makamaka zolimba komanso zowonekera .
Taganizirani izi, zinthu monga mabotolo amadzi omwe mumagwiritsa ntchito, zidebe zapulasitiki zosungiramo chakudya, ndi zitseko za zakudya ndi zakumwa zina zam'chitini zingakhale ndi BPA.
Kalekale, BPA inkagwiritsidwa ntchito m'zinthu zambiri. Komabe, pamene panali kukambirana padziko lonse za zoopsa zake pa thanzi, mabungwe monga FDA (Food and Drug Administration) ku United States, makamaka FDA, anapempha makampani opanga mabotolo a ana, makapu oziziritsa, ndi zitini za mkaka wa ana kuti asiye kugwiritsa ntchito BPA. Chifukwa chake, zinthu zambiri za ana zomwe zili pamsika tsopano zilibe BPA , kutanthauza kuti, zilibe BPA. Komanso, makampani ambiri opanga mabotolo amadzi ndi zidebe za chakudya tsopano asiya kugwiritsa ntchito BPA mwaufulu. Chifukwa chake, pali zinthu zochepa kwambiri zomwe zili ndi BPA m'nyumba mwathu tsopano kuposa momwe zinalili zaka makumi angapo zapitazo. Komabe, BPA si chinthu chomwe chaletsedwa kotheratu.
Ndi malo ati omwe angakhale ndi BPA?
BPA, mankhwala omwe akhala akugwiritsidwa ntchito kulimbitsa mapulasitiki kwa zaka zoposa 40, akupezeka m'malo ambiri otizungulira. Kafukufuku akusonyeza kuti oposa 90% a ife tili kale ndi BPA yochepa m'matupi athu. Imatha kulowa m'matupi athu osati kudzera mu zinthu zomwe timagwiritsa ntchito zokha, komanso kudzera mumlengalenga, fumbi, ndi madzi.
Zinthu zomwe zimapezeka kawirikawiri zomwe zingakhale ndi BPA ndi izi:
- Mabotolo ena amadzi apulasitiki
- Chipinda chamkati cha zakudya ndi zakumwa zam'chitini
- Zidebe zosungiramo chakudya zopangidwa ndi pulasitiki
- Zipangizo zina zachipatala
- Zotsekera mano
- Ma CD (ma CD)
Akatswiri amanena kuti ngakhale makampani ena angatchule makontena awo kuti "Opanda BPA," mwina akugwiritsa ntchito ma bisphenols ena ofanana ndi BPA, monga BPS kapena BPF. Palinso mafunso okhudza momwe alili otetezeka, kotero ndi bwino kugwiritsa ntchito makontena agalasi nthawi iliyonse yomwe zingatheke.
Kodi zinthu zimenezi zimalowa bwanji m'thupi mwathu?
Njira yaikulu yomwe BPA imalowera m'thupi lathu ndi kudzera mu chakudya ndi zakumwa zomwe timamwa. BPA imapezeka m'zinthu monga chakudya cham'zitini, madzi apulasitiki okhala ndi mabotolo, ndi mabokosi a nkhomaliro a polycarbonate, ndipo imatha kulowa m'chakudya kapena chakumwa chomwe chilimo.
Chofunika kwambiri ndi kutentha . Mukayika chinthu chotentha mu chidebe cha pulasitiki, mwachitsanzo, mukayika mpunga womwe mumabweretsa ku ofesi mu bokosi la chakudya cha pulasitiki pamene ukadali wotentha, pali mwayi waukulu kuti mankhwala awa asungunuke ndi kulowa mu chakudya. BPA ingathenso kufalikira kwa mwana kudzera mu mkaka wa m'mawere.
Kodi BPA ndi yoipa kwambiri pa thanzi lathu?
Anthu anayamba kuda nkhawa ndi izi pambuyo poti kafukufuku wa nyama adapeza kuti kupezeka ndi BPA yambiri kumalumikizidwa ndi matenda monga kuperewera kwa mimba, matenda a shuga, kunenepa kwambiri, matenda a mtima, ndi kuthamanga kwa magazi. Kafukufuku wina mwa anthu wapezanso kulumikizana pakati pa BPA ndi matenda ena. Komabe, sizinatsimikizidwe mwachindunji kuti BPA ndiye chifukwa cha matenda amenewo. Pakadali pano, pali maphunziro omwe amatsutsana ndi zotsatirazi.
Komabe, padakali mkangano wokhudza zotsatira zomwe BPA ingayambitse m'thupi. Tiyeni tiwone zoopsa zimenezo.
| Chiwopsezo cha thanzi chomwe chingakhalepo | Kufotokozera |
|---|---|
| Zotsatira pa kuchuluka kwa mahomoni | Akatswiri ena amakhulupirira kuti BPA imagwira ntchito ngati mahomoni m'thupi, zomwe zimasokoneza kuchuluka kwa mahomoni ndi chitukuko chabwinobwino, makamaka mwa ana osabadwa, makanda, ndi ana aang'ono. Zotsatira za kafukufuku wa nyama ndi zosakanikirana. |
| Mavuto a ubongo ndi khalidwe | Pulogalamu ya National Toxicology ya FDA yayang'ana kwambiri zotsatira zomwe BPA ingathe kubweretsa pa ubongo ndi khalidwe la ana. |
| Kuopsa kwa khansa | Kafukufuku wina wa zinyama wasonyeza kugwirizana pakati pa kukhudzana ndi BPA ndi chiopsezo chowonjezeka cha khansa mtsogolo. |
| Matenda a mtima | Kafukufuku awiri apeza kuti akuluakulu omwe ali ndi BPA yambiri m'thupi lawo ali ndi mwayi waukulu wopeza matenda a mtima. Koma sizikudziwika ngati izi zimachitika chifukwa cha BPA yokha. |
| Zochitika zina | Ngakhale kuti kafukufuku wachitika pa mgwirizano pakati pa BPA ndi matenda monga kunenepa kwambiri, matenda a shuga, ndi ADHD, palibe umboni wokwanira wa izi. |
Ndani amene ali pachiwopsezo chachikulu?
Kafukufuku wambiri akusonyeza kuti makanda ndi ana aang'ono ndi omwe ali pachiwopsezo chachikulu cha zotsatira za BPA, chifukwa matupi awo akadali kukula ndipo sangathe kuchotsa zinthu zovulaza kuposa akuluakulu.
Kodi tingatani kuti tidziteteze ku BPA?
Maphunziro akupitilirabe pankhaniyi. Pakadali pano, pali njira zosavuta zomwe mungachite kuti mupewe BPA. Mwa kutsatira izi, mutha kusamalira thanzi lanu komanso la banja lanu popanda mantha osafunikira.
- Chepetsani kugwiritsa ntchito pulasitiki momwe mungathere. Mwina sizingatheke kuchotsa pulasitiki kwathunthu. Koma chepetsani kugwiritsa ntchito ziwiya zapulasitiki, makamaka zakudya zamafuta (sambal, margarine, mayonesi) ndi zakudya zotentha.
- Gwiritsani ntchito ziwiya zagalasi, zadothi, kapena zachitsulo chosapanga dzimbiri. Izi ndizoyenera kwambiri kusungiramo chakudya komanso zakudya kapena zakumwa zotentha.
- Musatenthetse ziwiya za pulasitiki. Musamayike mu microwave kapena mabokosi a pulasitiki mu chotsukira mbale. Kutenthako kumatha kuswa pulasitiki pakapita nthawi ndikutulutsa BPA.
- Sankhani zinthu zopanda BPA. Mabotolo ambiri a ana, makapu, ndi zinthu zina tsopano ali ndi mawu oti "Opanda BPA" olembedwa bwino.
- Chepetsani kudya zakudya zam'chitini. Zitini zambiri zimatha kukhala ndi BPA mkati mwa mkati mwawo.
- Yang'anani code yobwezeretsanso pa pulasitiki. Ngati pali kansalu kakang'ono pansi pa chidebe cha pulasitiki chokhala ndi nambala 3 kapena 7 mkati, mwina kangakhale ndi BPA.
- Samalani posankha mkaka wa ana. Makampani ambiri tsopano amagwiritsa ntchito zitini zopanda BPA. Ngati pali kukayikira kulikonse kuti chitinicho chili ndi BPA, akatswiri ena amati ndi bwino kusankha mkaka wa ufa m'malo mwa mkaka wamadzimadzi, chifukwa zakumwa zimatha kuyamwa BPA.
Ngati muli ndi mafunso ena okhudza izi, chonde titumizireni uthenga.Musaope kulankhula ndi dokotala. Iye adzakupatsani upangiri wolondola kwambiri.
Uthenga Wopita Nawo Kunyumba
- BPA ndi mankhwala omwe amapezeka mu mapulasitiki ndi zitini zina.
- Malingaliro asayansi ndi osakanikirana pankhani ya momwe imakhudzira thupi la munthu, koma ndikofunikira kusamala, makamaka pa thanzi la ana aang'ono.
- Palibe chifukwa chochita mantha, koma mutha kuchepetsa kukhudzidwa ndi BPA mwa kutsatira njira zosavuta.
- Pewani kuyika zinthu zotentha m'mabotolo apulasitiki. Nthawi zonse gwiritsani ntchito mabotolo agalasi kapena achitsulo chosapanga dzimbiri ngati n'kotheka.
- Kuchepetsa kudya zakudya zam'chitini ndi njira yabwino yochepetsera kukhudzana ndi BPA.
