UMadhuri, umama wezingane ezimbili oneminyaka engu-32 ubudala, weza emtholampilo wami ekuseni ngalolo suku wangibuza ngelukuluku elikhulu nokwesaba.
"Dkt. Priya, ngihlala ngiphekela umndeni wethu ilayisi esitsheni sokupheka ilayisi. Kodwa muva nje ngibone ephephandabeni ukuthi ilayisi lingase libe ne -arsenic, ikhemikhali eyingozi emzimbeni. Ingabe lokhu kuyiqiniso, dokotela? Ingabe lokhu kuzolimaza izingane zami ezincane? Ayikho indlela esingakugwema ngayo lokhu?" kubuza uMadhuri.
Ngamthulisa uMadhuri ngathi, "Madhuri, umbuzo owubuzile ubaluleke kakhulu. Namuhla, ama-95% emindeni apheka irayisi esitofini ngokulinganisa amanzi. Le ndlela yokupheka ngaphandle kokuhlunga amanzi yandisa amathuba okuba i-arsenic elayisini ingene emizimbeni yethu. Ngakho-ke namuhla, ake sixoxe ngokuthi i-arsenic ingena kanjani elayisini, ukuthi iyilimaza kanjani imizimba yethu, nokuthi singayisusa kanjani i-arsenic elayisini sisebenzisa izindlela zesayensi ezazisetshenziswa okhokho bethu."
I-arsenic ivelaphi elayisini?
I-Arsenic iyisakhi samakhemikhali esenzeka ngokwemvelo ngamanani amancane kakhulu enhlabathini, emanzini nasemoyeni. Kodwa-ke, i-arsenic itholakala ngamanani amakhulu ezibulala-zinambuzane kanye nemithi yokubulala ukhula (imithi yokubulala ukhula) kanye nomanyolo wamakhemikhali ovame ukusetshenziswa kwezolimo zanamuhla.
Njengoba izitshalo zerayisi zimunca amanzi amaningi kunezinye izitshalo ngesikhathi sokukhula, i-arsenic encibilika enhlabathini nasemanzini imuncwa kalula futhi ibekwe ezinhlamvini zerayisi. Ucwaningo luye lwabonisa ukuthi irayisi iwumthombo oyinhloko wokudla we-arsenic engena emzimbeni womuntu. I-Arsenic ngokuyinhloko inezinhlobo ezimbili:
1. I-Arsenic Engokwemvelo: Ayinabo ubuthi obuncane.
2. I-Arsenic Engaphili: Lolu uhlobo oluyingozi kakhulu lwe-arsenic.
🚨 Amafulegi Abomvu Obuthi Obuningi Be-Arsenic Obudinga Ukwelashwa Okusheshayo
Izimpawu ezilandelayo eziyingozi zingase zivele ngenxa yokuqongelela ngokweqile kwe-arsenic emzimbeni (i-Arsenic Poisoning), futhi esimweni esinjalo, kufanele kutholakale usizo lwezokwelapha ngokushesha:
- Ubuhlungu obukhulu esiswini kanye nokuhlanza okuqhubekayo.
- Uhudo olunamanzi olunephunga elingavamile, elifana nephunga likagalikhi.
- Ukuba ndikindiki/ukuthuthumela ezandleni nasezinyaweni.
- Amabala amnyama esikhumbeni angacacile kanye nemisipha eqinile nebuhlungu.
Umonakalo wesikhathi eside emzimbeni obangelwa yi-arsenic
Ukuqongelela isikhathi eside kwe-arsenic engeyona engokwemvelo elayisini kungabangela izifo ezinkulu:
1. Umthelela ezinganeni ezincane:
Izingane ezincane zizwela kakhulu ku-arsenic ngoba i-metabolism yazo ishesha uma iqhathaniswa nosayizi womzimba wazo.
- Ukwehla kwe-IQ (isilinganiso sobuhlakani): Ukukhula kwamangqamuzana obuchopho kungaphazamiseka, okuholela ekuphazamisekeni kokufunda kanye nentuthuko yengqondo ezinganeni.
- Ukuzivikela komzimba okubuthakathaka: Ukwanda kokuthambekela kokugula njalo.
2. Umthelela kubantu abadala:
- Ingozi Yomdlavuza: Ukuchayeka isikhathi eside ku-arsenic kwandisa ingozi yomdlavuza wesikhumba , umdlavuza wamaphaphu, kanye nomdlavuza wesinye .
- Isifo senhliziyo nesifo sikashukela: Silimaza izindonga zemithambo yegazi, sandise ingozi yokuhlaselwa yinhliziyo, futhi siphazamise ukusebenza kwe-insulin, okuholela kusifo sikashukela.
Ucwaningo lwesayensi ngezindlela zokupheka irayisi
Ososayensi benze izivivinyo eziningana ngenani le-arsenic elisusiwe ngesikhathi sokupheka ilayisi:
- Ucwaningo luka-Andrea Raab kanye nethimba: Babonise ukuthi uma sisebenzisa isilinganiso samanzi esincane esivame ukusisebenzisa ukupheka ilayisi esitofini selayisi (njengezinkomishi zamanzi ezingu-2.5 ngenkomishi eyodwa yelayisi), i-arsenic elayisini ayisuswa nhlobo, futhi ifakwa emzimbeni kanye nelayisi.
- Ucwaningo luka-M. Azizur Rahman kanye nethimba: Bathole ukuthi ngokufaka amanzi engeziwe ngenkathi bepheka ilayisi bese behlunga amanzi asele ngemva kokuba ilayisi seliphekiwe (i-Draining Method), ngaphezu kuka-50% we-arsenic engaphili equkethwe elayisini isuswa kanye namanzi.
Ukuhlakanipha kwesayensi kokhokho bethu
Ogogo nomkhulu bethu babevame ukupheka ilayisi esitofini ngokufaka amanzi engeziwe ebhodweni elikhulu. Ngemva kokuba ilayisi seliphekiwe, babesebenzisa isihluzo ukuze bahluze amanzi e-bran asele (amanzi e-rice porridge).
Nakuba babengazi isizathu sesayensi salokhu ngaleso sikhathi, ucwaningo lwamakhemikhali lwanamuhla luqinisekisile ukuthi indlela engcono kakhulu nenempilo yokususa i-arsenic elayisini kwakuyindlela "yokuhlunga iphalishi" eyayisetshenziswa okhokho bethu.
Izinyathelo ezi-5 okufanele uzilandele ukuze upheke ilayisi ngokuphephile
Unganciphisa kalula inani le-arsenic elayisi ekhaya ngokulandela lezi zinyathelo:
1. Geza irayisi kahle: Ngaphambi kokupheka, hlanza irayisi kahle. Ukuhlanza kususa cishe u-10% we-arsenic engaphandle kwerayisi.
2. Ukucwilisa ilayisi: Cwilisa ilayisi emanzini okungenani amahora angu-4-8 noma ubusuku bonke ngaphambi kokupheka. Bese ukhipha amanzi bese ugeza futhi.
3. Ukwengeza amanzi engeziwe: Engeza amanzi avamile aphindwe kasithupha (izinkomishi eziyisithupha zamanzi ngenkomishi eyodwa yelayisi) bese upheka.
4. Khipha amanzi asele: Ngemva kokuba irayisi seliphekiwe, khipha amanzi asele esitofini selayisi noma ebhodweni bese ulisusa ngokuphelele.
5. Sebenzisa amanzi ahlanzekile: Uma uhlala ezindaweni lapho i-arsenic itholakala khona emanzini amaningi (isib. izindawo zaseRajarata), sebenzisa amanzi ahlanziwe (i-Filter/RO Water) esikhundleni samanzi omthombo wokuwasha nokupheka ilayisi.
Okumele Ukwenze Nokungafanele Ukwenze
| ✔️ Izinto okufanele uzenze (Okufanele Uzenze) | ❌ Okungafanele ukwenze |
|---|---|
| Engeza ukudla okuhlukahlukene ekudleni kwezingane zakho. Ngaphezu kwelayisi, nikeza amazambane endawo afana ne-kurakkan, i-thanahal, kanye ne-cassava. | Unganiki ubisi lwelayisi njengobisi oluyinhloko oluthatha indawo yobisi ezinganeni ezingaphansi kweminyaka emi-5 ubudala. |
| Uma uthenga irayisi, zama ukukhetha izinhlobo zelayisi zendawo ezikhuliswe ngendlela yemvelo. | Ungapheki ilayisi ngqo esitofini sokupheka ilayisi ngaphandle kokuligeza kahle nokulicwilisa. |
| Uma ilayisi seliphekiwe, ungashiyi i-rice cooker ku-"Warm" kuze kube yilapho amanzi omile, kodwa khipha amanzi ngokushesha. | Khuthaza abalimi ukuthi banciphise ukusetshenziswa okungadingekile komanyolo wamakhemikhali kanye nemithi yokubulala ukhula ekulimeni. |
❓ Eminye imibuzo ongase ube nayo (Imibuzo Ebuzwa Njalo)
Ingabe i-arsenic ingasuswa ngokuphelele ngokugeza nokucwilisa ilayisi? ▼
Cha, ayikwazi ukususwa ngokuphelele. Nakuba ukugeza nokucwilisa kuzosusa okunye, iningi lenani elisele lingasuswa ngokupheka emanzini amaningi bese kuhluzwa amanzi.
Kungani kungafanele ukunikeza izingane ezincane ubisi lwelayisi? ▼
Ubisi lwelayisi luqukethe amazinga aphezulu kakhulu e-arsenic engakhiqizi. Leli nani le-arsenic, uma liqhathaniswa nesisindo somzimba sezingane ezincane, lingabangela umonakalo omkhulu ekukhuleni kwazo nasebuchosheni, ngakho akufanele linikezwe izingane ezingaphansi kweminyaka emi-5.
Ingabe iklabishi elibomvu liqukethe i-arsenic eningi kuneklabishi elimhlophe ?
Yebo, ngokuvamile, ungqimba lwangaphandle lwelayisi (i-bran/i-husk) luvame kakhulu ukuqongelela i-arsenic. Nakuba ilayisi elibomvu noma ilayisi elinsundu eline-bran linomsoco kakhulu, okuqukethwe kwe-arsenic kungase kube phezulu kancane kunelayisi elimhlophe. Ngakho-ke, kubalulekile ukucwilisa nokuhlunga amanzi lapho upheka ilayisi le-bran.
Ungapheka kanjani ilayisi esitofini selayisi ngaphandle kwe-arsenic? ▼
Ungapheka ilayisi esitofini selayisi ngokufaka amanzi engeziwe. Uma ilayisi seliphekiwe kahle, cisha isitofini selayisi, khipha amanzi asele, bese uvula isitofini (esibekweni esifudumele) ukuze womise ilayisi kancane.
