| Abstract: | In 2000, 63 (polished) white rice samples were collected in eight administrative areas all over South Korea and analyzed for
16 elements by inductively coupled plasma atomic emission spectrometry (ICP-AES). Potassium had the highest content, next
to Mg, Ca, Si, Zn, Na, Al and Fe. Most of the samples contained worldwide average concentrations of essential and trace elements
in rice grains reported by various researches. For inter-area differences in those elements in the rice, the statistical analysis
showed no significant differences (p > 0.05) among the eight administrative areas, suggesting that inter-area differences were not substantial in most cases.
Thus, the present data can be used as national background levels of elements in rice produced in South Korea. Using the published
data on daily consumption of rice in South Korea, it was possible to estimate the daily intake of As, Cd, Cu, Pb and Zn via
rice. The results showed that a regular consumption of rice produced in Korea plays an important role in accumulation of essential
and trace elements in Korean, especially for farm-households consuming relatively large amounts of rice. |
