Abstract
The contents of 17 metals in 134 vegetables, 67 fruits, 10 potatoes and 15 fungi, collected from markets in Osaka Prefecture from 1983 to 1985, were determined by inductively coupled plasma (ICP) atomic emission spectrometry, and satisfactory results were obtained as regards accuracy and speed of operation. Analytical results for Ca in Chinese vegetables (taisai and chingentsuai) revealed high levels of 1091ppm and 736ppm, respectively. On the other hand, fungi contained P at high levels, though the concentration of Ca was found to be low.Recoveries of 85.3-115% were obtained for the 17 elements when added to brown rice.This method was applied to the analysis of “Rice Flour-Unpolished (NIES No. 10-1)”, and the results were in satisfactory agreement with the certified reference values.
