Recently the attention of the trace elements is arisen to the biochemical importances and the biochemical significances have been discussed and shown by several workers. And also UN-narcotic Committee has shown that geographical difference of Opium based on the produced area, would be significant on its contents of trace elements. The problem of Rice in Korea is urgently important on the nutritional and agricultural view points for the soil improvement of its production and for the betterment of health program. In order to check the adaptability of cultural problems to the different qualities of the with regards to the kinds of rice species and in order to know the consumption of trace elements through rice, the contents of trace elements on 40 samples of the polished rice sampled from the different areas consisting in 8 kinds of rice species are studied on contents of Al, Mn, Ni, Zn, Co, Cu and Fe in this paper. Though the further wide spread studies should be carried out, it seems that Al, Fe and Ni contents show little differences by the kinds of rice species and Cu, Al, Mn, Zn, and Ni contents show geographically little differences. But these differences are not significant statistically. The Co was not detected from the rice samples. It is not clear whether Co content in rice is a undetectable amount or the Co is absent in rice at all.
