| Research Abstract |
Dietary intake of silicon and other elements were investigated for the adult and childereninhabitants in Japan, Chaina and Korea. For this purpose, 24-hour food duplicate sampleswere collected. The minerals in each sapmle were instrumentally measured by use ofICP-AES,AAS and ICP-MS.
(1)There was a wide variation of silicon concentrations of thedrinking water by home and region respectively among Japan, China and Korea. Itsfindings would be considered to be large effects on the dietary silicon intake .
(2)Silicon andother element concentration of finger nail for children show a wide variation by each andthe kindergarten in China and Korea.
