usawoti Iodized iye kabanzi njengendlela esikhundleni zemvelo eChina ngo-1995, khona-ke baqala futhi ngakhula iziguli ezinomdlavuza yegilo. Leli qiniso sibonakala sethusa.

iodized usawoti abaphikisi bakholelwa ukuthi kubangela ukulimala ngenakugwemeka, futhi ukukhiqizwa yayo kumele kumiswe. Baphinde bathi kuyasiza kakhulu ukusebenzisa ithebula usawoti ngaphandle iodine. Izibalo zamuva libike ukuthi iphesenti abanomdlavuza yegilo liye landa, okwenza kube ukuthuthukiswa uhlobo aphakeme abantu abanomdlavuza e-Beijing. Kule minyaka eyi-10, ukukhula isilinganiso lezi izifo landa ngabantu 225%.

umbono uchwepheshe

Umdlavuza wegilo - okuvame kakhulu umdlavuza zokugula intsha esikhulakhulile (kufika ku-10% nokudlanga sabantu). Kuyinto evamile ngaphezulu amantombazane. Lapho umdlavuza medullary we yegilo indlala intsha babe 5.1%.

Noma kunjalo, izazi awukanikezi ukuwamukela lo mqondo wokuthi akukho ukuhlobana yangempela phakathi abanale nkinga nosawoti iodized. Bacabanga ukuthi kuphephile futhi kusebenza ngempumelelo nokuvimbela ukuntula iodine.

Ucwaningo lubonisa ngokucacile ukuthi abukho ubufakazi ngqo ukuthi ukusetshenziswa kasawoti iodized kuholela umdlavuza yegilo. I-International Council futhi wakhipha isimemezelo esenziwa ukusetshenziswa usawoti iodized engahlobene nesenzakalo umdlavuza yegilo.

Ukuthuthukiswa umdlavuza kungenxa yezizathu eziningi, kuhlanganise izici zendawo ezungezile nokushiswa ngemisebe, yofuzo. Gu Juni, Beijing esibhedlela okunomsoco, uthi ukuba zibancishe usawoti iodized ukunciphisa ingozi yokuba nesifo somdlavuza yegilo. Nokho, lokho kungase kubangele nezinye izinkinga zempilo ezingathi sína, ezifana ubuthulu ngisho ukulimala kobuchopho ezinganeni.

iodine isibalo

EChina, okuqukethwe iodine usawoti 30 mg kilogram per. I umhlali isilinganiso ukusetshenziswa China yansuku zonke angaphansi kuka-10 grams.

U.S Kunconywa umthamo sangemihla kuyinto 300 micrograms iodine, futhi ngo-1100 ngokuhambisana-World Health Organization. Lokhu kusho ukuthi ukusetshenziswa micrograms akukho kuka 300 iodine ngosuku ngokuphelele ephephile zonke izindinganiso wezokwelapha.

5 KIO3 + KI + 3H2SO4 = 3I2 + K2SO4 + 3H2O 3.

isiphetho

Salt iyona ebaluleke kakhulu izakhi ezibalulekile ukuze umsebenzi elilungile ukuphila komzimba womuntu. It ehilelekile ukuthwala umoya-mpilo nezakhi ezondla umzimba, kanye imisipha ukunyakaza (ukudluliselwa nerve amaza). Njengoba umzimba awukwazi uqobo ukuthuthukisa sodium izinqolobane we ketshezi kufanele njalo agcwaliswa.
