Yiqiniso, umkhiqizo onjalo osetshenziswa kabanzi kumelwe uphephe, akunjalo? Kodwa, ngeshwa, akunjalo. Amanye amakhemikhali akupulasitiki angaphelela ekudleni kwethu, futhi abakhiqizi abaphoqelekile ukudalula ukuthi yimaphi amakhemikhali abawasebenzisayo.
Ipulasitiki ngokuqinisekile yenza ukuphila kwethu kube lula, kodwa i-aftertaste ebabayo ekudleni okugcinwe noma okuphekwe epulasitiki isikhathi eside kusho okuthile.
Ukuthembela kwethu epulasitiki kudala izinkinga eziningi. Sethula kuwe izizathu eziyisi-7 zokuthi kungani kufanele ulahle ipulasitiki, ikakhulukazi uma kuziwa ekudleni.
1. I-BFA (Bisphenol A)
Kunezinhlobo eziningi ezahlukene zepulasitiki, futhi ngayinye inikezwa inombolo ethile. Abathengi bangasebenzisa lezi zinombolo ukuze banqume ukuthi ipulasitiki ethile ingagaywa kabusha yini.
Uhlobo ngalunye lwepulasitiki lukhiqizwa ngokwe "iresiphi" ethile. Ipulasitiki #7 iyipulasitiki eqinile ye-polycarbonate futhi yilolu hlobo oluqukethe i-BPA.
Ngokuhamba kwesikhathi, i-BPA yakha emzimbeni wethu futhi inomthelela ekubhujisweni kwesistimu ye-endocrine, futhi yandisa ingozi yokuthuthukisa izifo eziyingozi njengomdlavuza nesifo senhliziyo. Izingane, kuhlanganise nezinsana ngisho nezinsana, zizwela kakhulu emiphumeleni ye-BPA ekudleni kwethu. Yingakho i-BPA ingasetshenziswa ezintweni ezifana namabhodlela ezingane nezinkomishi.
Kodwa i-BPA ingacasha ezintweni eziningi: emathini esobho e-aluminium, amathini ezithelo nemifino, amaphepha okulidida, amathini e-soda, ama-DVD nezinkomishi ze-thermos. Zama ukuthenga imikhiqizo ebhalwe ukuthi “BPA free” ukuze ukhawulele imiphumela eyingozi yale nto emzimbeni wakho.
2. Ama-Phthalates
Amapulasitiki athambile, asetshenziswa ezinhlotsheni eziningi zamathoyizi ezingane, aqukethe ama-phthalates, okwenza izinto ziphenduleke. Amathoyizi avame ukwenziwa ngePVC, noma ipulasitiki engu-#3. Ama-Phthalates awaboshiwe ngamakhemikhali ku-PVC, ngakho-ke angena kalula esikhunjeni noma kunoma yikuphi ukudla ahlangana nakho.
Ucwaningo lubonisa ukuthi ama-phthalates alimaza i-endocrine kanye nezinhlelo zokuzala zezingane ezisakhula futhi angase akhulise ngisho nobungozi bomdlavuza wesibindi. Futhi iphunga elibangela ikhanda le-PVC entsha liphakamisa ukuthi le nto inobuthi.
Kungaba nzima ukugwema ngokuphelele lezi zinto. Ngezinye izikhathi zingatholakala emikhiqizweni yokunakekelwa komuntu siqu, ngakho-ke bheka ilebula "ye-phthalate-free" emikhiqizweni wena nomndeni wakho eniyisebenzisayo ukunakekela isikhumba sakho.
3. I-Antimony
Wonke umuntu uyazi ukuthi amabhodlela amanzi epulasitiki asevele abe inhlekelele yemvelo, kodwa akuwona wonke umuntu oqaphela ukuthi usongo olunjani empilweni yethu. Ipulasitiki esetshenziswa kulawa mabhodlela ingu-#1 PET futhi isebenzisa ikhemikhali ebizwa ngokuthi i-antimony njenge-catalyst ekukhiqizeni kwayo. Abacwaningi basola ukuthi i-antimony yandisa ingozi yomdlavuza.
Ucwaningo olwengeziwe luyadingeka ukuze kutholwe izingozi ezigcwele ze-antimoni emanzini, kodwa i-antimoni isivele yaziwa ngokuphuma emabhodleleni anamanzi. Imiphumela emibi yezempilo iye yabikwa kubantu abasebenza ngobungcweti nge-antimony ngokuthinta noma ngokuhogela ikhemikhali.
4. Izithasiselo ezilwa namagciwane
Uhlobo lwepulasitiki iningi leziqukathi zethu zokugcina ukudla ezenziwe nge-polypropylene (#5 ipulasitiki). Isikhathi eside ipulasitiki #5 ibithathwa njengenye indlela enempilo kunepulasitiki ye-BPA. Kodwa-ke, kusanda kutholakala ukuthi izithasiselo ze-antibacterial ziyaphuma kuwo.
Lokhu kusanda kutholwa, futhi luseluningi ucwaningo okufanele lwenziwe ukuze kutholwe umonakalo ongadalwa ipulasitiki engunombolo 5 emzimbeni. Kodwa-ke, amathumbu ethu kufanele agcine ibhalansi ethambile yamagciwane ukuze asebenze kahle, futhi ukwengeza izithasiselo ze-antibacterial emzimbeni kungaphazamisa le bhalansi.
5. I-Teflon
I-Teflon iwuhlobo lwepulasitiki engagxili emboza amabhodwe athile namapani. Abukho ubufakazi bokuthi iTeflon inobuthi ngokwemvelo emzimbeni, kodwa ingakhulula amakhemikhali anobuthi emazingeni okushisa aphakeme kakhulu (ngaphezu kwama-degree angu-500). I-Teflon iphinde ikhiphe amakhemikhali ayingozi phakathi nokukhiqizwa nokulahlwa kwayo.
Ukuze ugweme ukuchayeka kule nto, khetha izitsha ezenziwe ngezinto eziphephile. Inketho enhle kungaba insimbi ephonsiwe kanye nezitsha zokupheka ze-ceramic.
6. Ukungenisa okungenakugwema
Imboni yamakhemikhali iyavuma ukuthi ayikho indlela yokugwema izingcezu ezincane zepulasitiki ekudleni, kodwa igcizelela ukuthi inani lezakhi ezinjalo lincane kakhulu. Okuvame ukunganakwa ukuthi amaningi alawa makhemikhali awakwazi ukucutshungulwa ngumzimba, kodwa kunalokho ahlala ezicubu zethu ezinamafutha futhi aqhubeke enqwabelana lapho iminyaka eminingi.
Uma ungakakulungeli ukuyeka ukusebenzisa ipulasitiki, kunezindlela ezimbalwa zokunciphisa ukuchayeka kwakho. Isibonelo, ungalokothi ushise ukudla ngepulasitiki, njengoba lokhu kwandisa inani lepulasitiki elingeniswayo. Uma usebenzisa ipulasitiki yokupakisha ukumboza ukudla, qiniseka ukuthi ipulasitiki ayihlangani nokudla.
7. Ukulimala kwemvelo kanye nokuphazamiseka kochungechunge lokudla
Akuzona izindaba ukuthi ipulasitiki ithatha isikhathi eside ukubola futhi inqwabelane ezindaweni zokulahla imfucumfucu ngesivinini esishaqisayo. Okubi nakakhulu ukuthi iphelela emifuleni nasezilwandle zethu. Isibonelo esiyinhloko iGreat Pacific Garbage Patch, inqwaba enkulu yepulasitiki entantayo emane nje ingesinye “seziqhingi” eziningi zikadoti eziye zakheka emanzini omhlaba.
Ipulasitiki ayiboli, kodwa ngaphansi kwethonya lelanga namanzi, ihlehla ibe yizinhlayiya ezincane. Lezi zinhlayiya zidliwa izinhlanzi nezinyoni, ngaleyo ndlela zingene ohlelweni lokudla. Yiqiniso, ukudla izinto ezinobuthi eziningi kangaka kulimaza nenani lalezi zilwane, kunciphisa inani lazo futhi kusongela ukushabalala kwezinhlobo ezithile zezilwane.
Akulula ukuqeda ngokuphelele ipulasitiki ngenxa yokuba khona kwayo yonke indawo ekudleni kwethu. Nokho, kunezinyathelo ezimbalwa ezilula ongazithatha ukuze unciphise umthelela.
Ukuze uqalise, shintshela ezitsheni zengilazi, izitsha zokuphuza, namabhodlela ezingane. Sebenzisa ithawula lephepha ku-microwave ukuze ubambe i-splatter, hhayi ukugoqa kwepulasitiki. Kungumqondo omuhle futhi ukuhambisa iziqukathi zepulasitiki zokugeza izandla kunokuzifaka emshinini wokuwasha izitsha, futhi ulahle noma yimuphi upulasitiki oklwetshiwe noma osontekile.
Ngokunciphisa kancane kancane ukuncika kwethu kupulasitiki, sizoqinisekisa ukuthi impilo yoMhlaba kanye nabo bonke abakhileyo kuwo izothuthuka kakhulu.
