Kuyinto esiyenzayo sonke, uma sithenga ibhodlela lamanzi esitolo, futhi uma siqeda ukuphuza amanzi, sigcwalisa ibhodlela elifanayo bese silisebenzisa futhi. Mhlawumbe sinalo lelo bhodlela izinsuku eziningi. Senza lokhu ngoba sikhathalela imvelo, noma ngoba asinaso esinye isitsha uma kwenzeka isimo esiphuthumayo. Kodwa wake wacabanga ukuthi kuphephile kangakanani empilweni yakho ukusebenzisa kabusha ibhodlela elifanayo lepulasitiki ngokuphindaphindiwe? Namuhla, sizoxoxa ngalokho kanye.
Ingabe wonke amabhodlela epulasitiki ayafana? Isho ukuthini inombolo engezansi kwebhodlela?
Uma uthatha ibhodlela lepulasitiki bese ubheka phansi, uzobona inombolo ngaphakathi konxantathu. Lokhu kubizwa ngokuthi 'i-Resin Identifying Code' (RIC). Lokhu kukutshela ukuthi ibhodlela lenziwe ngohlobo luni lwepulasitiki. Akukutsheli ukuthi lingaphinde lisetshenziswe noma cha, kukutshela nje uhlobo lwepulasitiki. Amabhodlela amanzi esiwaphuzayo avame ukwenziwa ngamapulasitiki aphinde asetshenziswe. Ake sibheke izinhlobo eziyinhloko.
| Inombolo yonxantathu (RIC) | Uhlobo lwepulasitiki | Ngokuvamile kubonakala |
|---|
| 1 | I-Polyethylene terephthalate (i-PET noma i-PETE) | Amabhodlela amanzi avamile namabhodlela eziphuzo ezibandayo esiwathenga esitolo aklanyelwe ukusetshenziswa kanye. |
| 2 | I-polyethylene enobukhulu obuphezulu (i-HDPE) | Amabhodlela aqinile kancane, aqinile njengamabhodlela obisi, amabhodlela e-shampoo, namabhodlela okugeza. |
| 7 | Okunye (ngokuvamile i-Polycarbonate) | Amanye amabhodlela amanzi amakhulu (asetshenziswa ezindaweni zokuhambisa amanzi), amanye amabhodlela asetshenziselwa ezemidlalo. |
Umbuzo wangempela uwukuthi - ingabe amakhemikhali akupulasitiki ayangena emanzini?
Enye yezinto ezikhathaza kakhulu abantu lapho besebenzisa amabhodlela epulasitiki kabusha ukuhlanzwa kwamakhemikhali, noma 'ukuhlanzwa kwamakhemikhali'. Kalula nje, yilapho amanye amakhemikhali asetshenziswa ukwenza ipulasitiki ehlanza kancane kancane emanzini esiwaphuzayo. Izimbangela eziyinhloko zalokhu ukuchayeka emazingeni okushisa aphezulu (njengokushiya ibhodlela emotweni ipakwe elangeni), ukuchayeka elangeni, kanye nokushiya ibhodlela lamanzi endaweni yalo isikhathi eside.
Yimaphi la makhemikhali angaba yingozi?
- I-Antimony: Lena ikhemikhali esetshenziswa ekukhiqizeni ipulasitiki ye-PET. Ingangena emanzini lapho amazinga okushisa aphezulu. Ukuchayeka isikhathi esifushane kungabangela isicanucanu , ukuhlanza , kanye nesifo sohudo . Ukuchayeka isikhathi eside kungakhuphula ne-cholesterol kanye namazinga kashukela egazini . Ngakho-ke, ungalokothi ushiye amabhodlela amanzi epulasitiki elangeni. Lapho izinga lokushisa legumbi liphansi kakhulu.
- I-Bisphenol A ( BPA ): Lokhu kuvame ukusetshenziselwa ukwenza uhlobo 7 (i-polycarbonate) futhi ngezinye izikhathi uhlobo 3 lwepulasitiki. Ezinye izifundo zibonise ukuthi ukuchayeka ku-BPA kungandisa ingozi yomfutho wegazi ophakeme , isifo sikashukela sohlobo 2 , kanye nesifo senhliziyo . Kungathinta nokukhula kobuchopho bezingane ezingakazalwa kanye nezingane ezincane. Izindaba ezinhle ukuthi i-BPA manje ayivunyelwe emabhodleleni ezingane nasezinkomishini eziphuzayo.
- Ama-phthalates: Lawa ngamakhemikhali asetshenziselwa ukwenza amapulasitiki athambe futhi aguquguquke. Angatholakala kwamanye amathoyizi kanye nokupakishwa kokudla kwe-PVC. Izifundo zibonisa ukuthi angaphazamisa ukukhula okuvamile kanye nokuthuthukiswa kobuchopho ezinganeni.
Uma ukhathazekile ngala makhemikhali, sebenzisa imikhiqizo enelebula ethi ayinayo i-BPA . Futhi gwema izitsha zepulasitiki ezinelebula ethi 3, 6, noma 7 ngangokunokwenzeka.
Usongo olukhulu kunamakhemikhali! Lokho amagciwane!
Nakuba abantu abaningi bengazi,
ukukhula kwamagciwane kuyingozi enkulu empilweni kunokukhishwa kwamakhemikhali ngokusebenzisa amabhodlela epulasitiki kabusha. Cabanga ngakho, uma uphuza amanzi ebhodleleni, amagciwane asemlonyeni wakho aqoqana esivalweni nasentanyeni yebhodlela. Futhi amagciwane asezandleni zethu nawo asakazeka kulo lonke ibhodlela.
Eqinisweni, abakhiqizi benza la mabhodlela ukuze asetshenziswe kanye kuphela. Isizathu esiyinhloko salokho ingozi yokwanda kwaleli gciwane.
Uma usebenzisa ibhodlela elifanayo izinsuku eziningi, kukhula amagciwane amaningi ngaphakathi kwalo. Futhi, la magciwane afihla kahle
emihuzukweni nasemaqhubu avela lapho usebenzisa ibhodlela. Kunzima kakhulu futhi ukususa la magciwane ngokuphelele ngensipho evamile, ngoba ukuma kwebhodlela kwenza kube nzima ukuhlanza ingaphakathi. Uma la magciwane engena emzimbeni, kungabangela ukucasuka kwesisu kanye nohudo.
Ngakho-ke iyiphi inketho engcono kakhulu nephephile?
Uma ucabanga ngakho konke lokhu, into engcono kakhulu ongayenza ukunciphisa ukusetshenziswa kabusha kwamabhodlela amanzi epulasitiki ngangokunokwenzeka.
- Sebenzisa amabhodlela engilazi noma ensimbi engagqwali: Lezi yizinketho ezinhle kakhulu. Kulula kakhulu ukuzihlanza, asikho isidingo sokukhathazeka ngokuvuza kwamakhemikhali, futhi zilungele imvelo. Uma usuthenge ibhodlela elihle, ungalisebenzisa iminyaka eminingi.
- Uma kufanele usebenzise ibhodlela lepulasitiki kabusha: Uma kufanele usebenzise ibhodlela lepulasitiki kabusha, zama ukungalisebenzisi isikhathi esingaphezu kosuku . Futhi, ligeze kahle ngamanzi ashisayo nensipho ngemva kokusetshenziswa ngakunye bese ulivumela lome ngokuphelele.
- Ukuphinda usebenzise: Uma usuqedile ukuyisebenzisa, ungayilahli nje emgqonyeni kadoti, kodwa uyiyise esikhungweni sokuphinda usebenzise. Kuyindlela enhle yokusiza imvelo.
Uma uneminye imibuzo mayelana nalokhu, noma uma ucabanga ukuthi into efana nalena ibangela izimpawu zakho (isib. ukucasuka kwesisu), kungcono
ukubona udokotela womndeni wakho ukuze akunike iseluleko.
Umlayezo Wokuya Nawe Ekhaya
- Amabhodlela amanzi epulasitiki avamile (inombolo 1 - i-PET) owathenga esitolo aklanyelwe ukusetshenziswa kanye kuphela .
- Ukukhula kwamagciwane kuyingozi enkulu empilweni kunokuvuza kwamakhemikhali ngesikhathi sokusetshenziswa kabusha.
- Ungalokothi ushiye amabhodlela amanzi epulasitiki elangeni noma ezindaweni ezinokushisa okuphezulu (isib. ngaphakathi ezimotweni).
- Uma kufanele uyisebenzise kabusha, yigeze futhi uyihlanze kahle nsuku zonke. Kodwa gwema ukusebenzisa ibhodlela elifanayo isikhathi eside.
- Inketho ephephile nengcono kakhulu ukuthenga ibhodlela elingasetshenziswa kabusha elenziwe ngengilazi noma ngensimbi engagqwali .
Amabhodlela epulasitiki, amabhodlela amanzi, izingozi zempilo, amagciwane, i-BPA, ukuhlanzwa kwamakhemikhali, ukuphepha kwamabhodlela epulasitiki, ukusebenzisa kabusha amabhodlela epulasitiki, amathiphu ezempilo eSinhala
