Kodi polypropylene yomwe timagwiritsa ntchito tsiku lililonse ndi yotetezekadi?

Pulasitiki ili paliponse m'miyoyo yathu ya tsiku ndi tsiku, sichoncho? Kuyambira kukhitchini mpaka magalimoto omwe timagwiritsa ntchito, chilichonse chimapangidwa ndi pulasitiki. Chifukwa chakuti ndi chofala kwambiri, nthawi zambiri timaganiza kuti mitundu yonseyi ya pulasitiki ndi yotetezeka pa thanzi lathu. Koma kodi ndi zoonadi? Ndi mitundu yosiyanasiyana ya zinthu zopangidwa ndi pulasitiki, tingadziwe bwanji zomwe zili zabwino pa thanzi lathu ndi zomwe zili zoipa? Zinthu zambiri zomwe timagwiritsa ntchito, kuphatikizapo ziwiya za kukhitchini ndi mabokosi a nkhomaliro, zili ndi mtundu wotchedwa polypropylene. Tiyeni tikambirane za izi lero.

Kodi polypropylene iyi ndi chiyani?

Mwachidule, polypropylene ndi mtundu wa pulasitiki. Imagwiritsidwa ntchito popanga chilichonse kuyambira makapu a yogurt ogulidwa m'sitolo mpaka mabotolo amadzi mpaka mabokosi a nkhomaliro. Chimodzi mwa ubwino wake waukulu ndikuti imatha kubwezeretsedwanso mosavuta. Ichi ndichifukwa chake yakhala imodzi mwa mitundu yotchuka kwambiri ya pulasitiki padziko lonse lapansi masiku ano.

Mukhoza kudziwa mosavuta ngati chinthu cha pulasitiki chapangidwa ndi polypropylene. Ngati chili ndi nambala '5' mkati mwa chizindikiro cha kubwezeretsanso cha katatu pansi, zikutanthauza kuti chapangidwa ndi polypropylene.

Kodi polypropylene imagwiritsidwa ntchito chiyani?

Polypropylene ndi mtundu wa pulasitiki womwe ndi wothandiza kwambiri. Umagwiritsidwa ntchito m'magawo ambiri chifukwa cha mphamvu yake, mtengo wake wotsika, komanso kusinthasintha kwake. Tiyeni tiwone chomwe chimagwiritsidwa ntchito makamaka.

Kodi izi zili ndi BPA yoopsa?

Nkhani yabwino ndi iyi! Polypropylene ilibe Bisphenol-A (BPA).

BPA ndi mankhwala omwe amagwiritsidwa ntchito kulimbitsa mapulasitiki. Yakhala ikugwiritsidwa ntchito m'mapaketi azakudya kuyambira m'ma 1960.

Kafukufuku wasonyeza kuti mukatentha zinthu monga zidebe zapulasitiki, mbale, ndi mabotolo, mankhwala otchedwa BPA amasungunuka kuchokera mu pulasitiki ndikulowa m'chakudya chomwe timadya. Sizabwino konse. Chifukwa BPA ikalowa m'matupi mwathu, imayamba kugwira ntchito ngati hormone ya estrogen m'matupi mwathu. Izi zingayambitse mavuto angapo azaumoyo. Mwachitsanzo, zimatha kusintha magwiridwe antchito a chitetezo chamthupi, kukhudza kuthekera kobereka ana, kufulumizitsa msinkhu mwa atsikana, ndikuwonjezera chiopsezo cha matenda amtima.

Tiyeni tiphunzirenso za mankhwala otchedwa Phthalates.

Nkhani ina yabwino ndi yakuti polypropylene ilibe mankhwala otchedwa phthalates.

Ma phthalates ndi gulu lina la mankhwala omwe amagwiritsidwa ntchito kufewetsa mapulasitiki, kuwapangitsa kukhala osinthasintha komanso olimba. Koma tsopano kafukufuku wapeza kuti ma phthalates nawonso ndi owopsa pa thanzi lathu. Angathe kuwononga dongosolo lathu la endocrine. Amapezeka mu chilichonse kuyambira nsalu za patebulo ndi mipando mpaka ma phukusi azakudya ndi zodzoladzola.

Mutha kukhudzidwa ndi ma phthalates m'njira zotsatirazi:

• Kumeza kudzera mu chakudya.
• Mwa kupuma.
• Mwa kumwa madzi odetsedwa.
• Mwa kulowa m'thupi kudzera pakhungu.

Ndiye kodi polypropylene ndi poizoni kwenikweni?

Polypropylene nthawi zambiri imaonedwa kuti ndi pulasitiki yotetezeka kugwiritsa ntchito. Yavomerezedwanso ndi mabungwe monga US Food and Drug Administration (FDA) kuti igwiritsidwe ntchito kamodzi kokha komanso mogwiritsidwanso ntchito.

Palibe maphunziro omwe akusonyeza kulumikizana mwachindunji pakati pa polypropylene ndi khansa mwa anthu. Koma pali china chatsopano chomwe tiyenera kulabadira apa. Ndipo ndicho ma microplastics . Ndiko kuti, tinthu ta pulasitiki tomwe ndi tating'ono kwambiri kuti tisawonekere ndi maso. Kafukufuku wambiri akufunikabe kuchitidwa pa zotsatira za ma polypropylene microplastics awa pa matupi athu ndi chilengedwe.

Kodi ubwino ndi kuipa kwa polypropylene ndi kotani?

Poyerekeza ndi mapulasitiki omwe ali ndi mankhwala owopsa monga BPA, polypropylene ndi njira ina yabwino kwambiri. Tiyeni tiwone zabwino zake zazikulu ndi zoyipa zake.

Chiwopsezo chachikulu cha thanzi cha polypropylene chimachokera ku mapulasitiki ang'onoang'ono omwe tidakambirana kale. Awa ndi ang'onoang'ono kwambiri kotero kuti amatha kulowa m'thupi lathu kudzera m'madzi omwe timamwa komanso chakudya chomwe timadya. Kafukufuku waposachedwa adapeza kuti tinthu tating'onoting'ono ta polypropylene tosaoneka bwino tingakhudze kukula kwa maselo a khansa ya m'mawere a anthu ndikuwonjezera kufalikira kwa khansa . Iyi ndi imodzi mwa maphunziro oyamba kuwonetsa momwe mapulasitiki ang'onoang'ono amakhudzira maselo a khansa ya anthu. Ngati muli ndi mafunso aliwonse okhudza izi, lankhulani ndi dokotala wanu.

Kodi mungagwiritse ntchito bwanji polypropylene mosamala?

Mwa kutsatira malamulo osavuta awa, mutha kugwiritsa ntchito zinthu za polypropylene mosamala.

• Gwiritsani ntchito zinthu zapulasitiki zokha zomwe zili ndi chizindikiro chopanda BPA .
• Musatenthetse chakudya m'zidebe zapulasitiki, makamaka mu microwave.
• Ngati muli ndi zinthu zapulasitiki zakale kuposa chaka cha 2012 , zichotseni, chifukwa zitha kukhala ndi BPA.
• Musagwiritsenso ntchito mabotolo amadzi kapena zidebe zina zokhala ndi code yobwezeretsanso nambala 1. Zapangidwa kuti zigwiritsidwe ntchito kamodzi kokha.
• Musalole mwana wanu wamng'ono kapena chiweto chanu kutafuna zoseweretsa zapulasitiki.
