Ipulasitiki ikhona yonke indawo ekuphileni kwethu kwansuku zonke, akunjalo? Kusukela ekhishini kuya ezimotweni esizisebenzisayo, konke kwenziwa ngepulasitiki. Ngenxa yokuthi ivame kakhulu, sivame ukucabanga ukuthi zonke lezi zinhlobo zepulasitiki ziphephile empilweni yethu. Kodwa ingabe kunjalo ngempela? Njengoba kunezinhlobo eziningi kangaka zamakhemikhali epulasitiki, sazi kanjani ukuthi yiziphi ezinhle empilweni yethu nokuthi yiziphi ezimbi? Izinto eziningi esizisebenzisayo, okuhlanganisa izitsha zasekhishini namabhokisi okudla kwasemini, ziqukethe uhlobo olubizwa ngokuthi i-polypropylene. Ake sixoxe ngalokhu namuhla.
Iyini le polypropylene?
Kalula nje, i-polypropylene uhlobo lwepulasitiki. Isetshenziselwa ukwenza yonke into kusukela ezinkomishini ze-yogurt ezithengwa esitolo kuya emabhodleleni amanzi kuya emabhokisini okudla kwasemini. Enye yezinzuzo zayo ezinkulu ukuthi ingaphinde isetshenziswe kalula. Yingakho isibe olunye lwezinhlobo zepulasitiki ezidumile kakhulu emhlabeni namuhla.
Ungabona kalula ukuthi into yepulasitiki yenziwe nge-polypropylene. Uma inombhalo othi '5' ngaphakathi kophawu lokuphinda usebenzise oluyinxantathu phansi, kusho ukuthi yenziwe nge-polypropylene.
Iyini i-polypropylene esetshenziselwa yona?
I-Polypropylene uhlobo lwepulasitiki oluwusizo kakhulu. Isetshenziswa emikhakheni eminingi ngenxa yamandla ayo, izindleko eziphansi, kanye nokuguquguquka kwayo. Ake sibone ukuthi isetshenziselwani ngokuyinhloko.
| Insimu yokusetshenziswa | Izibonelo |
|---|---|
| Ukupakisha | Ngenxa yokuthi ziqinile kakhulu futhi azibizi kakhulu, zisetshenziselwa ukwenza izinto ezifana nezinkomishi ze-yogurt, izinkomishi zokuphuza, amabhodlela amanzi, kanye nezitsha zokudla. |
| Izinto zasekhaya | Ipulasitiki emakhaya ethu isetshenziswa kabanzi ekwenzeni izimpahla ezisetshenziswayo njengezihlalo, amatafula, amathoyizi kanye nemithwalo. |
| Izingxenye zezimoto | Ngenxa yokuthi ayibizi futhi ingabunjwa kalula ibe yisimo esifunwayo, isetshenziselwa ukwenza amabhampa, izembozo zebhethri, amaphaneli angaphakathi eminyango, kanye namaphaneli ezinsimbi ezimotweni nasemaveni. |
| Izicelo zezokwelapha | Ngenxa yokuthi ziyamelana namakhemikhali namagciwane, zisetshenziselwa ukwenza izinto ezifana nesirinji yokujova, amathileyi okudla esibhedlela, izinkomishi zemithi, kanye nezitsha zikaPetri. |
Ingabe lokhu kuqukethe i-BPA eyingozi?
Nazi izindaba ezinhle! I-Polypropylene ayinayo i-Bisphenol-A (BPA).
I-BPA iyikhemikhali esetshenziselwa ukuqinisa ipulasitiki. Ibilokhu isetshenziswa ekupakisheni ukudla kusukela ngawo-1960.
Ucwaningo lukhombisile ukuthi uma ufudumeza izinto ezifana nezitsha zepulasitiki, amapuleti, namabhodlela, leli khemikhali elibizwa ngokuthi i-BPA liyancibilika epulasitikini bese lingena ekudleni esikudlayo. Lokho akuyona into enhle nhlobo. Ngoba lapho i-BPA ingena emizimbeni yethu, iqala ukusebenza njenge-hormone i-estrogen emizimbeni yethu. Lokhu kungabangela izinkinga eziningi zempilo. Isibonelo, kungashintsha ukusebenza kwesimiso somzimba sokuzivikela, kuthinte ikhono lokuthola abantwana, kusheshise ukuthomba kwamantombazane, futhi kwandise ingozi yesifo senhliziyo.
Ngakho-ke, hlala ubheka ilebula ethi “ayinayo i-BPA” uma uthenga imikhiqizo yepulasitiki. Futhi, gwema amapulasitiki anekhodi yokuvuselela 3 noma 7, njengoba engase abe ne-BPA. Gwema ukushisa izitsha zepulasitiki kuma-microwave noma nini lapho kungenzeka.
Ake sifunde futhi ngekhemikhali ebizwa ngokuthi ama-Phthalate.
Ezinye izindaba ezinhle ukuthi i-polypropylene ayinawo amakhemikhali abizwa ngokuthi ama-phthalates.
Ama-phthalates ayiqembu lamakhemikhali asetshenziselwa ukuthambisa amapulasitiki, okwenza abe lula futhi aqine. Kodwa manje ucwaningo luthole ukuthi ama-phthalates nawo ayingozi empilweni yethu. Angalimaza uhlelo lwethu lwe-endocrine. Angatholakala kukho konke kusukela ezindwangu zetafula kanye nefenisha kuya ekupakishweni kokudla kanye nezimonyo.
Ungavezwa kuma-phthalates ngezindlela ezilandelayo:
- Ukungena ngokudla.
- Ngokuphefumula.
- Ngokuphuza amanzi angcolile.
- Ngokumuncwa emzimbeni ngesikhumba.
Ngakho-ke ingabe i-polypropylene inobuthi ngempela?
I-polypropylene ngokuvamile ibhekwa njengepulasitiki ephephile ukuyisebenzisa. Ivunyelwe ngisho nayizikhungo ezifana ne-US Food and Drug Administration (FDA) ukuze isetshenziswe kanye futhi isetshenziswe kabusha ezitsheni zokudla.
Azikho izifundo okwamanje ezibonisa ukuxhumana okuqondile phakathi kwe-polypropylene nomdlavuza kubantu. Kodwa kukhona okusha okudingeka sikunake lapha. Futhi lokho yi -microplastics . Okusho ukuthi, izinhlayiya zepulasitiki ezincane kakhulu ukuba zingabonwa ngamehlo enyama. Kusadingeka kwenziwe ucwaningo oluningi ngemiphumela yalezi microplastics ze-polypropylene emizimbeni yethu kanye nasemvelweni.
Yiziphi izinzuzo kanye nokungalungi kwe-polypropylene?
Uma kuqhathaniswa namapulasitiki aqukethe amakhemikhali ayingozi njenge-BPA, i-polypropylene iyindlela enhle kakhulu. Ake sibheke izinzuzo zayo eziyinhloko kanye nokungalungi kwayo.
| Izinzuzo | Izingozi |
|---|---|
| Isisindo esincane. | Iba buthakathaka kalula emazingeni okushisa aphansi kakhulu. |
| Iqinile, kodwa iguquguquka. | Iyanyamalala kancane kancane uma ivezwa elangeni. |
| Izindleko zokukhiqiza ziphansi. | Akuboli uma kufakwe enhlabathini. |
| Kuvunyelwe ukusetshenziswa ekudleni. | Ingozi enkulu kunazo zonke: ama-microplastic . |
| Imelana nokushisa futhi ihlala isikhathi eside. | |
| Kungaphinde kusetshenziswe. |
Ingozi enkulu yezempilo evela ku-polypropylene ivela kuma-microplastic esikhulume ngawo ngaphambili. Lawa mancane kakhulu kangangokuthi angangena emizimbeni yethu ngamanzi esiwaphuzayo kanye nokudla esikudlayo. Ucwaningo lwamuva nje luthole ukuthi izinhlayiya ze-polypropylene ezincane ezingafani zingathinta ukukhula kwamangqamuzana omdlavuza webele womuntu futhi zinegalelo ekuqhubekeni komdlavuza . Lolu olunye lwezifundo zokuqala ezibonisa ukuthi ama-microplastic athinta kanjani amangqamuzana omdlavuza womuntu. Uma unemibuzo ngalokhu, khuluma nodokotela wakho.
Ungayisebenzisa kanjani i-polypropylene ngokuphepha?
Ngokulandela le mithetho elula, ungasebenzisa imikhiqizo ye-polypropylene ngokuphephile.
- Sebenzisa imikhiqizo yepulasitiki enelebula elingenayo i-BPA kuphela.
- Ungalokothi ufudumale ukudla ezitsheni zepulasitiki, ikakhulukazi kuma-microwave.
- Uma unezinto zepulasitiki ezindala kuno-2012 , zilahle, ngoba zingase zibe ne-BPA.
- Ungasebenzisi kabusha amabhodlela amanzi noma ezinye izitsha ezinekhodi yokuvuselela inombolo 1. Zenzelwe ukusetshenziswa kanye kuphela.
- Ungavumeli ingane yakho encane noma isilwane sakho sasekhaya sihlafune amathoyizi epulasitiki.
Ngokuvamile, kuphephile ukusebenzisa izitsha zeglasi esikhundleni sepulasitiki noma nini lapho kungenzeka khona ukugcina nokuphakela ukudla.
Umlayezo Wokuya Nawe Ekhaya
- I-Polypropylene (inombolo 5) iyindlela ephephile kakhulu kunezinye izinhlobo eziningi zepulasitiki ngoba ayinayo i-BPA nama-phthalates.
- Gwema ukusebenzisa noma yiluphi uhlobo lwepulasitiki ukufudumeza ukudla. Izitsha zengilazi noma ze-ceramic zilungele lokho.
- Ama-microplastic ayingozi enkulu empilweni, ngakho-ke kunengqondo ukunciphisa ukusetshenziswa kwepulasitiki ngangokunokwenzeka.
- Uma uthenga noma usebenzisa umkhiqizo wepulasitiki, hlola njalo ikhodi yokuvuselela kuwo. Inombolo 5 yi-polypropylene.
