3Contents and distribution of rare earth elements in wheat seeds显示文摘Contents of 15 rare earth elements (REEs) in the seeds of 60 breeds of wheat have been analyzed by the inductively-coupled plasma mass spectrometry (ICP-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 seeds is 10 11-108 g -g-1, 3-4 levels lower than in soils. The distribution pattern is light REEs higher in contents and slight Eu-anomaly, similar to that in soils. The data obtained in this study can accurately represent the background content of REEs in wheat seeds.LIANG Tao ZHANG Shen WANG Lijun YAN Beizhan WANG Naifen LIU Husheng WANG Xiaoyan 2000Chinese Science Bulletin2000,45,7:0
