Ngaba wakha wacinga ukuba kunokubakho into enobungozi efihliweyo emanzini esiwaselayo nokutya esikutyayo yonke imihla engabonakaliyo emehlweni ethu, engenancasa, kwaye engenavumba? Inokwenzeka ngokwenene. Yiyo loo nto i-arsenic . Mhlawumbi ukhe waliva eli gama kwiphephandaba nakwiTV. Kodwa inyani yile, kubaluleke kakhulu kuthi sonke ukuba siqaphele impembelelo enokuba nayo kwimpilo yethu. Ngoko masithethe ngale nto namhlanje, ngendlela onokuyiqonda.
Yintoni iArsenic?
Ngamafutshane, i-arsenic sisiqalelo sekhemikhali esifumaneka ngokwemvelo emhlabeni nasematyeni eplanethi yethu. Njengentsimbi ne -calcium . Kodwa ingxaki kukuba, i-arsenic inetyhefu emizimbeni yethu . Yongezwa kwindalo esingqongileyo ngenxa yokuqhuma kweentaba-mlilo, ngaphakathi emhlabeni, nakwinkunkuma yemizi-mveliso.
I-Arsenic ikhona kwiindlela ezimbini eziphambili.
1. I-Organic Arsenic: Le yi-arsenic edityaniswe ne-carbon element. Ihlala ifumaneka kwizicubu zezityalo nezilwanyana. Ayinabungozi kangako kunezinye iintlobo.
2. I-Arsenic engaphiliyo : Olu lolona hlobo luyingozi kakhulu nolunobungozi . Olu lolona hlobo ludla ngokungcolisa amanzi okusela kunye nomhlaba. Olu hlobo lukhutshwa luvela kwimizi-mveliso kunye neenkuni ezicociweyo.
Xa sithetha " ngetyhefu ye-arsenic", sithetha kakhulu ngokutya i-arsenic engaphiliyo.
Oku kungena njani emizimbeni yethu?
Kukho iindlela ezininzi eziphambili i-arsenic enokungena ngazo emizimbeni yethu. Kwane-World Health Organization (WHO) ithi ukungcoliswa kwamanzi angaphantsi komhlaba yi-arsenic yeyona ngxaki inkulu yempilo yoluntu ehlabathini.
- Ngokusela amanzi: Le yeyona ndlela iphambili neyona iyingozi. Amanzi omthombo, asetyenziswa ngabantu abaninzi, ingakumbi kumazwe afana nelethu, anokungcoliswa yi-arsenic efumaneka emhlabeni kwezinye iindawo. Ekubeni i-arsenic ingenancasa, umbala, okanye ivumba, akukho ndlela yokwazi ukuba le tyhefu ikhona na emanzini ngaphandle kokuyivavanya.
- Ukusuka ekutyeni:I-arsenic esemhlabeni ifunxwa zizityalo. Oku kunokukhokelela kumanqanaba aphezulu e-arsenic kwezinye ukutya, ingakumbi irayisi. Ezinye iintlanzi , iinkukhu, kunye neekhowa nazo zinokuba ne-arsenic. Nangona kunjalo, ekubeni le yinkqubo yendalo, akunakwenzeka ukuyisusa ngokupheleleyo i-arsenic ekutyeni.
- Ngokuphefumla: I-Arsenic ingaginywa nangokuphefumla uthuli okanye umsi onayo (umzekelo, ovela kwezinye iifektri).
Into ebalulekileyo kukuba xa i-arsenic ingena emzimbeni, iqokelelana kancinci kancinci. Endaweni yokuba ifumane idosi enkulu ngaxeshanye, kukuqokelelwa kancinci kancinci kwe-arsenic ngokuhamba kwexesha okubangela izifo ezihlala ixesha elide neziyingozi.
Zithini iimpawu zetyhefu ye-arsenic?
Iimpawu zoku ziyahluka ngokuxhomekeke kubungakanani kunye nobude bokuginywa kwe-arsenic. Zinokwahlulwa zibe ziindidi ezimbini: ubuthi obubukhali, obuvela xa kuginywa isixa esikhulu ngaxeshanye, kunye nobuthi obungapheliyo, obuvela xa kuginywa isixa esincinci kangangexesha elithile.
| Iimpawu zetyhefu ye-arsenic | |
|---|---|
| 1. Iimpawu ezibukhali - Xa kutyiwa isixa esikhulu ngaxeshanye | |
| Inkqubo yokugaya ukutya | Intlungu ebuhlungu esiswini, isicaphucaphu, ukuhlanza (ngamanye amaxesha kunye negazi), kunye norhudo olunzima. |
| Ezinye iimpawu | Incasa efana neyentsimbi okanye yegalikhi emlonyeni, intloko ebuhlungu kakhulu, iintlungu zemisipha. |
| Kwimeko enzima | Ukusebenza kwentliziyo kunye nenkqubo yemithambo-luvo kunokuphazamiseka kwaye nokufa kunokubakho. Ukuba unale mpawu, kufuneka uye kwiYunithi yoNyango oluNgxamisekileyo (ETU) yesibhedlele ngoko nangoko. |
| 2. Iimpawu Ezingapheliyo - Iimpawu ezikhula ngokuhamba kwexesha | |
| Utshintsho lolusu | Ukutyeba kolusu (ingakumbi iintende zezandla neenyawo), utshintsho kumbala wolusu (amabala amnyama okanye amhlophe), kunye namadyungudyungu amancinci eluswini. |
| Inkqubo yemithambo-luvo | Iimeko ezinje ngokuba ndindisholo, ukulahlekelwa zimvakalelo, kunye nokukhubazeka okuncinci. |
| Ezinye iziphumo zexesha elide | Ukuphazamiseka kwesingqisho sentliziyo, ukozela, isicaphucaphu, ukubona okufipheleyo, ukuxhuzula, kunye nomngcipheko ophezulu weentlobo ngeentlobo zomhlaza. |
Zithini iziphumo zempilo ezihlala ixesha elide?
Kulapho kufuneka sigxile khona kakhulu. Ukuchanabeka kwi-arsenic ixesha elide kunokubangela iingxaki zempilo ezinzulu kakhulu.
- Umhlaza: I-arsenic engaphiliyo yi-carcinogen eyaziwayo. Yimbangela enkulu yomhlaza wolusu, umhlaza wemiphunga, umhlaza wesinyi, umhlaza wezintso, kunye nomhlaza wesibindi.
- Isifo seswekile: Uphando lufumanise unxibelelwano phakathi kokungena kwi-arsenic kunye neemeko ze-metabolic ezifana nesifo seswekile.
- Isifo sentliziyo: Sinokuchaphazela ukusebenza kwentliziyo kwaye sibangele uxinzelelo lwegazi oluphezulu kunye nezinye izifo zentliziyo.
- Iziphumo ebantwaneni: Abantwana abachaphazeleka yi-arsenic besebancinci basengozini enkulu yokuhlaselwa zizifo ezahlukeneyo xa sele bebadala. Ezi ziphumo zinokuhlala iminyaka emva kokuba ukubonakaliswa kwazo kuyekile.
Masifunde ngokuxilongwa kunye nonyango.
Ukuba unezi mpawu okanye ukrokrela ukuba unetyhefu ye-arsenic, ngokuqinisekileyo kuya kufuneka ubone ugqirha . Ugqirha uza kukubuza ngeempawu zakho aze, ukuba kuyimfuneko, acele uvavanyo lokujonga inqanaba le-arsenic emzimbeni wakho.
- Uvavanyo lomchamo
- Uvavanyo lwegazi
- Uhlalutyo lweenzipho neenwele
Xa kufikwa kunyango, akukho "nyango" lulodwa olusebenzayo lokunyanga ityhefu ye-arsenic. Eyona nto ingcono onokuyenza kukuphepha ukuginya i-arsenic.
Nangona kunjalo, kwezinye iimeko, ingakumbi kwiimeko zotyhefu olukhawulezileyo, unyango olubizwa ngokuba yi-"chelation therapy" lusetyenziswa ukususa i-arsenic emzimbeni. Nangona kunjalo, lunokuba nemiphumo emibi kwaye ke ngoko lwenziwa kuphela phantsi kweliso likagqirha.
Ukongeza, uphando oluthile lubonise ukuba ukuthatha idosi yemihla ngemihla ye-vitamin folic acid kunokunciphisa amanqanaba e-arsenic egazini kubantu abachaphazeleka yi-arsenic ixesha elide. Nangona kunjalo, kubalulekile ukuthetha nogqirha wakho ngaphambi kokuba wenze nayiphi na kwezi zinto.
Ukuba ukrokrela ukuba kukho nayiphi na ityhefu, ungafowunela iZiko loLwazi lweTyhefu leSizwe kwiSibhedlele sikaZwelonke saseColombo ukuze ufumane ingcebiso.
Ungazikhusela njani kwi-arsenic?
Ukuthintela kungcono ngokuphindwe kaliwaka kunonyango. Ngoko ke sizikhusela njani kolu tshaba lungabonakaliyo?
- Vavanya amanzi akho equla: Ukuba usebenzisa amanzi equla, kubalulekile ukuba uwavavanye rhoqo ukuze ubone ukuba awanazo na i-arsenic nezinye iintsimbi ezinzima. Ungakwenza oku ngokuqhagamshelana noMhloli wezeMpilo yoLuntu (PHI) okanye iarhente karhulumente efanelekileyo.
- Izihluzi zamanzi: Khumbula, izihluzi zamanzi eziqhelekileyo zasekhaya azikwazi ukususa i-arsenic. Izihluzi ezikhethekileyo (umz. i-reverse osmosis, i-alumina esebenzayo) ezenzelwe ngokukodwa ukususa i-arsenic ziyafuneka.
- Ukutya: Yitya ukutya okunesondlo okuneentlobo ngeentlobo zokutya, kunokuba uzigcinele uhlobo olunye lokutya, ingakumbi irayisi evela kwindawo enye.
- Ukhuseleko kwindawo yokusebenza: Ukuba usebenza kwishishini apho usenokuba uchanabeke khona kwi-arsenic (umz., ukumbiwa kwemigodi, iikhemikhali zezolimo), landela iinkqubo zokhuseleko ezibonelelwa ngumbutho wakho.
Umyalezo Wokuya Ekhaya
- I-Arsenic yityhefu eyingozi engenancasa, ivumba, okanye umbala kwaye inokufumaneka emanzini nakwezinye izinto zokutya.
- Ukuhlala ixesha elide ungaziboni izinto ezinjalo kunokukhokelela kwizifo ezinzulu ezifana nezifo zesikhumba, isifo seswekile, isifo sentliziyo kunye nomhlaza.
- Ukuba usebenzisa amanzi equla, kubaluleke kakhulu ukuba uwavavanye ukuze afumane i-arsenic.
- Ukuba uneempawu ezihlala ixesha elide ezifana notshintsho olungabonakaliyo lolusu okanye ukungacaci kwamalungu omzimba wakho, musa ukukuthatha lula oko uze ubone ugqirha.
- Ukuthintela lolona nyango lungcono, ngoko ke hlala ukhumbula amanzi akhuselekileyo kunye nokutya okunesondlo.
