| Abstract:: |
| Objective To obtain the concentrations and daily intakes of 15 rare earth elements in foods for adult men in four areas in China. Methods With duplicate portion study,120 mixed diet samples were collected from adult men in cities of Tianjin, Chengdu, Zhenjiang and Taiyuan, which belong to 4 areas with different dietary types in China. The concentrations of cerium, dysprosium, erbium, gadolinium, lanthanum, lutetium, holmium, neodymium, praseodymium, scandium, samarium, terbium, thulium, yttrium and ytterbium in these samples were determined by Inductively Coupled Plasma Mass Spectrometry(ICP-MS)after pretreatment, and the daily intakes of them were also calculated. Results The concentrations of 15 rare earth elements and their daily intakes in foods for adult men were obtained. Conclusions The concentrations of these elements in each area are consistent with normal distribution. The total rare earth element concentration in the diet of adult men ranges from 24.68 to 109.27 μg/g. The daily intake of total rare earth elements is about 24 μg/d. Reference values of the rare earth element concentrations in the diet and daily intake of Chinese adult men were updated. |
