Contents and distribution of rare earth elements in wheat seeds

Abstract

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 –10 8 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.

Contents and the biogeochemical characteristics of rare earth elements in wheat seeds

Abstract

Contents of fifteen rare earth elements (REEs) in the seeds ofsixty breeds of wheat collected from seed bank were measured byinductively coupled plasma mass spectrometry (ICP-MS). The distributionpatterns of contents of REEs in wheat seeds (n = 58) wereobserved and compared with their average level in soils (n =364). Differences among regions and between spring and winter wheat weretested. Comparison with literature data was also made. The results showthat the content of REEs in wheat seed ranges between10 −11 g · g −1 and10 −8 g · g −1 , 3–4 orderof magnitudes lower than that in soils. The distribution patterns arethat light REEs enriched and the Eu-anomaly is weak, similar to the soilcase. No obvious differences were found among different regions andbreeds. The data obtained in this study represent the contents of thefifteen REEs in wheat seeds.
