Contents and distribution of rare earth elements in wheat seeds

Contents of 15 rare each elements (REEs) in the seeds of 60 breeds of wheat have been analyzed by the inductively-coupled plasma mass spectrometry (IC P-MS). The distribution pattern of contents of REEs in wheat seeds has been observed and compared with that in soils. Comparison with literature data has also been made, The results show that the background of REEs in wheat s eeds is 10(-11)-10(-8) g . g(-1), 3 - 4 levels lower than in soils. The dis tribution pattern Is light REEs higher in contents and slight Eu-anomaly, s imilar to that In soils. The data obtained in this study can accurately rep resent the background content of REEs in wheat seeds.
