Ngaba ukhe wakhathazeka kancinci ngento epapashwe kumaphephandaba, kumabonwakude, nakwi-intanethi kutshanje? Libali lokuba irayisi esiyityayo kunye nezinye iziselo zeziqhamo zinokuba nekhemikhali enobuthi ebizwa ngokuba yi-arsenic. Le ntetho isasazeke ngakumbi malunga nejusi yeapile kunye neediliya, kunye nerayisi. Kuqhelekile ukuziva usoyika kancinci xa usiva oku. Ke namhlanje, masithethe ngento eyenzekayo ngokwenene, ukuba kufuneka soyike, kunye nento ekufuneka siyazi ngale nto.
Yintoni i-arsenic? Ingena njani ekutyeni?
Ngamafutshane, i-arsenic yinto efumaneka ngokwemvelo kumhlaba nasemanzini omhlaba . Yintsimbi enzima, njengelothe kunye ne-mercury. Kodwa ingxaki kukuba, ukongeza kule arsenic yendalo, i-arsenic ikwafakwa kwindalo esingqongileyo ngenxa yemisebenzi yabantu.
Cinga ngoku: Ngaphambili, abalimi babesebenzisa iikhompawundi ze-arsenic njengezibulali-zinambuzane kunye nezichumisi. Babezisebenzisa nokugcina iinkuni ezinyangiweyo. I-arsenic eyongezwe emhlabeni ngale ndlela inokuhlala emhlabeni iminyaka emininzi.
Umzekelo, uninzi lwamasimi erayisi kumazantsi e-United States ayekade engamasimi ekotoni. Izibulali-zinambuzane ezine-arsenic zazisetyenziswa kakhulu ukulawula i-cotton bollworm, izinambuzane ezitshabalalisa ikotoni. Ngoko ke, umhlaba usenokuba usenamanqanaba aphezulu e-arsenic nanamhlanje.
Eyona nto ibalulekileyo esinokuyiqonda koku kukuba xa izityalo zifunxa izondlo ezizifunayo emhlabeni, ukuba kukho i-arsenic kuloo mhlaba, izityalo zifunxa i-arsenic ngempazamo, zicinga ukuba sisondlo ezisidingayo.
Ziziphi ukutya okunokwenzeka ukuba ziqulathe i-arsenic?
Enyanisweni, phantse zonke izityalo zifunxa i-arsenic emhlabeni. Imifuno eluhlaza kunye neembotyi zinokuba ne-arsenic ephezulu kunee-nuts. Nangona kunjalo, ekubeni inani leembotyi esizityayo imihla ngemihla lincinci xa lithelekiswa nokutya okuqhelekileyo njengerayisi, inani le-arsenic engena emzimbeni ngazo nalo lincinci.
Ingqwalasela ekhethekileyo inikwa apha kwirayisi.
Isizathu soku kukuba irayisi ikhuliswa kwiindawo ezikhukuliswe ngamanzi. I-Arsenic yinto enyibilika lula emanzini. Ngenxa yoko, izityalo zerayisi ezikhula kwiindawo ezikhukuliswe ngamanzi zinamandla amakhulu okufunxa i-arsenic kunezityalo ezikhuliswe kumhlaba owomileyo.
Abaphandi bafumanise ukuba xa befumana ukhozo lwerayisi nge-X-ray, uninzi lwe-arsenic luhlala kwintsholongwane . Le nxalenye iyasuswa xa senza irayisi emhlophe (xa i-bran isusiwe). Oku kuthetha ukuba irayisi emdaka, ene-bran, inokuba noxinzelelo lwe-arsenic oluphezulu kunerayisi emhlophe.
Ukongeza, ukutya kwaselwandle kukwaqulathe amanqanaba aphezulu e-arsenic, kodwa iingcali ezininzi zikholelwa ukuba ukutya kwaselwandle kuqulathe uhlobo lwe-arsenic olungenabungozi kangako emizimbeni yethu.
Ziziphi iingxaki zempilo ezinokubakho xa i-arsenic ingena emzimbeni?
Lo ngumbuzo omkhulu kubo bonke abantu. Imiphumo yokungena kwe-arsenic emzimbeni iyahluka ngokuxhomekeke kubungakanani kunye nobude bokuchaphazeleka. Masiqonde oku ngokucacileyo ngetafile.
| Indlela yokuvezwa | Iziphumo ezinokubakho kwimpilo |
|---|---|
| Ukuvezwa ngaxeshanye kumanqanaba aphezulu kakhulu (okungaqhelekanga) |
|
| Ukuvezwa Okungapheliyo |
Musa ukoyika xa ubona ezi zinto. Oku kumalunga neengozi zokuchanabeka kwi-arsenic iminyaka emininzi . Ukutya irayisi nokusela isiselo seziqhamo ngosuku akuyi kubangela iziphumo ezibi kangaka.
Ngoko ke, ngaba simele siyeke ukusela iziselo zeziqhamo size sizinike abantwana?
Hayi, akufuneki siyeke yonke into ngaxeshanye. Iingcali zithi kufuneka sibe krelekrele. Ukuba wena okanye umntwana wakho nisela iziselo ezininzi zeziqhamo yonke imihla, ayingombono umbi ukunciphisa kancinci.
"Asinakuba ngabagqibeleleyo ngokupheleleyo kuyo yonke into. Ukuba sizama ukuba njalo, siya kusilela. Ukuba kukho into enokuphepheka lula, yiphephe, kodwa ungayicingi kakhulu."
Eyona nto ingcono kukuba,Endaweni yokutya ukutya okufanayo okuninzi, zama ukufaka iintlobo ngeentlobo zokutya ekutyeni kwakho ngendlela elinganiselayo.
Ngaba irayisi kunye nokutya okungeyomvelo kukhuselekile kule nkalo?
Lo ngumbuzo abantu abaninzi abawubuzayo. Ekubeni i-arsenic yinto ehlala emhlabeni iminyaka emininzi, awunakuthi ukutya okukhuliswe ngendlela yendalo akuna-arsenic. Kuba isityalo siyakufunxa emhlabeni. Ukuba kukho i-arsenic kuloo mhlaba, isityalo sinokukufunxa nokuba indlela yokulima injani.
Uyazi njani ukuba umzimba wakho une-arsenic ephezulu? Yintoni omele uyenze ukuba ukrokrela oku?
Ukuvezwa ixesha elide kumanqanaba aphantsi e-arsenic akwenzeki ukubangela iimpawu ezicacileyo. Abanye abantu banokubona umbala wolusu, njengamabala okanye iintsumpa ezincinci, ezandleni zabo, ezinyaweni nasemzimbeni ngokuhamba kwexesha.
Eyona nto ibalulekileyo:
Ukuba unesikrokro, uloyiko, okanye iimpawu zokuvezwa yi-arsenic ngokutya okanye emanzini, nceda ungazicingeli. Eyona nto ingcono onokuyenza kukubonana nogqirha wakho wosapho (GP) ukuze akunike ingcebiso.
Ukuba kuyimfuneko, ugqirha unokujonga ubungakanani be-arsenic emzimbeni wakho ngovavanyo lwegazi, umchamo, iinwele, okanye iinzipho.
Ukuba usela amanzi equla kwaye unamathandabuzo, ungavavanya isampuli yamanzi kwaye, ukuba kuyimfuneko, usebenzise izihluzi zamanzi ukususa i-arsenic emanzini. Ukuba ufuna ulwazi olukhawulezileyo malunga nayo nayiphi na ityhefu, ungafowunela iZiko loLwazi lweeTyhefu leSizwe kwiSibhedlele sikaZwelonke saseColombo ukuze ufumane ingcebiso. Nangona kunjalo, kubalulekile ukufuna ingcebiso kagqirha ngaphambi kokuba uthathe naluphi na unyango lwalo naluphi na uhlobo lwesifo.
Yintoni umahluko phakathi kwe-arsenic yendalo kunye ne-inorganic?
Oku kubuchwephesha kancinci, kodwa masiqonde ngokulula.
- I-Arsenic engaphiliyo: Ezi zizinto ezifumaneka kwindalo esingqongileyo (umhlaba, amanzi). Olu hlobo luthathwa njengolona lunobungozi kakhulu kwaye luyingozi kwimpilo yabantu.
- I-Arsenic ye-Organic: Ezi ziikhompawundi ze-arsenic ezenziwa kwizityalo nakwizilwanyana. Kusekho ingxoxo malunga nobuthi bazo.
Umyalezo Wokuya Ekhaya
- I-Arsenic ifumaneka ngokwemvelo emhlabeni nasemanzini, ngoko ke okunye ukutya esikutyayo kusenokuba nenani elincinci layo.
- Nangona kukho iingxelo zamanqanaba e-arsenic kwirayisi nakwezinye iziselo zeziqhamo, musa ukoyika ngokungeyomfuneko oku.
- Eyona ndlela ilungileyo kukuphepha ukutya ukutya okuninzi kohlobo olufanayo ixesha elide kwaye utye ukutya okunesondlo okwahlukeneyo.
- Irayisi emdaka enebran inokuba namanqanaba aphezulu e-arsenic kunerayisi emhlophe, ngoko ke licebo elihle ukutshintshiselana phakathi kweentlobo ezahlukeneyo zerayisi.
- Ukuba nje ukutya kubhalwe "organic" akuthethi ukuba akunayo i-arsenic.
- Ukuba uneengxaki zempilo okanye iimpawu kule meko, nceda udibane nogqirha wakho ukuze ufumane iingcebiso ezifanelekileyo kunye novavanyo, endaweni yokuthembela kulwazi olukwi-intanethi.
