Kodi mudatengapo chidole cha pulasitiki chokongola ndipo mudadzifunsapo kuti n’chiyani chimachiteteza kuti chisasweke? Mwina chimapangidwa ndi PVC—pulasitiki yodziwika bwino kwambiri m’zoseweretsa za ana, kuyambira zoseweretsa zosambira za rabara mpaka zomangira zolimba. Koma nayi nkhani: PVC yokha ndi yosokoneza pang'ono. Imasweka mosavuta ikatentha (taganizirani kuyendetsa galimoto dzuwa kapena kungoseweredwa ndi zambiri) ndipo imatulutsa mankhwala oipa panthawiyo. Pamenepo ndi pomwe “zokhazikika” zimalowa. Zili ngati zothandizira zomwe zimapangitsa PVC kukhala yolimba, yosinthasintha, komanso yokhazikika.
Koma si zinthu zonse zokhazikika zomwe zimapangidwa mofanana. Ndipo pankhani ya zoseweretsa za ana, "zopanda poizoni" si mawu ongotchulidwira chabe—ndi nkhani yaikulu.
Ana Amasewera Mosiyana (Ndipo Zimenezo Ndi Zofunika)
Tiyeni tinene zoona: ana sasamalira zoseweretsa mofatsa. Amazitafuna, amazithira madzi, ndipo amazipaka pankhope zawo zonse. Ngati chosungira chidole chili ndi zinthu zovulaza monga lead, cadmium, kapena mankhwala enaake oopsa, poizoniyo amatha kutuluka—makamaka pulasitiki ikayamba kutha kapena kutentha.
Matupi ang'onoang'ono amakhala okhudzidwa kwambiri ndi poizoniyu. Ubongo ndi ziwalo zawo zikukulirakulirabe, kotero ngakhale pang'ono chabe zingayambitse mavuto akulu: ganizirani ziphuphu pakhungu, kusokonezeka kwa mimba, kapena choipa kwambiri, mavuto a nthawi yayitali okhudzana ndi kukula. Zoletsa poizoni? Amapewa zinthu zoipa, kotero simuyenera kuda nkhawa ndi zomwe zikutuluka mwana wanu akamaluma chidole chake chomwe amakonda kwambiri.
It'Si Za Chitetezo Chokha—Zoseweretsa Zimakhalanso Zokhalitsa
Zolimbitsa thupi zopanda poizoni sizimangoteteza ana okha—zimathandiza kuti zoseweretsa zizikhala bwino. PVC yokhala ndi zolimbitsa thupi zabwino imakhala yowala komanso yokongola (palibe chikasu chachikulu pakatha miyezi ingapo), imakhala yosinthasintha (palibe ming'alu yosweka ikapindika), ndipo imapirira kuseweretsa movutikira. Izi zikutanthauza kuti chidole chomwe mwana wanu amakonda lero sichidzasanduka chisokonezo chophwanyika mwezi wamawa.
Kodi mwaonapo momwe zoseweretsa zina zapulasitiki zowonekera bwino zimakhalira ndi mitambo kapena ming'alu? Muzidzudzula zinthu zokhazikika. Zosakhala poizoni, monga calcium-zinc kapena barium-zinc blends, zimapangitsa PVC kukhala yowoneka bwino komanso yomveka bwino, ngakhale mutasamba nthawi zambiri, kukoka, ndi kutaya.
Mmene Mungadziwire Zinthu Zabwino
Simukusowa digiri ya sayansi kuti muwone ngati chidole chili chotetezeka. Ingochitembenuzani ndikusanthula chizindikirocho:
Pewani zizindikiro zofiira izi: Mawu ngati “chitsulo,” “cadmium,” kapena “organic tin” (mtundu wa mankhwala oletsa poizoni) ndi zizindikiro zochenjeza.
Yang'anani magetsi obiriwira awa: Mawu monga “opanda poizoni,” “opanda lead,” kapena “akukwaniritsa EN 71-3″ (muyezo wokhwima wa chitetezo ku Europe) amatanthauza kuti yayesedwa.
Mitundu yotetezeka yokhazikika: “Kashiamu-zinki"kapena"barium-zinki"Zolimbitsa thupi ndi anzanu—ndizolimba pa kusunga PVC yolimba koma yofatsa kwa ana aang'ono."
Mfundo Yofunika Kwambiri
Ponena za zoseweretsa za ana, “chokhazikika cha PVC chopanda poizoni"Ndi mawu ochulukirapo kuposa kungonena zachikale. Ndi nkhani yokhudza kuteteza mwana wanu akamasewera, ndikuwonetsetsa kuti zoseweretsa zake zomwe amakonda zimakhalapo nthawi zonse zovuta komanso zosangalatsa.
Nthawi ina mukadzagula zoseweretsa, tengani kamphindi kuti muwone chizindikirocho. Mwana wanu adzakuthokozani (ndipo nthawi zambiri amavutika chifukwa cha zoseweretsa zosweka) ndipo mudzapumula mosavuta podziwa kuti nthawi yawo yosewerera ndi yotetezeka komanso yosangalatsa.
