In oder to prevent of the hazard' by trace metals such as Hg, Cd, Pb, Cu and Zn, the contents of these metals were analyzed. Hg, Cd, and Pb were not . detected , but the mean contents of Cu and Zn were O.33ppm and 0.356 ppm, respectively. It seems that the higher oontents of Cu and Zn in beas sprouts was the results of relative high concentration of itself. These contents has no problean in now, but the more sanitary management in manufacture and in bean producing region will be needed.
