目的获得我国4地区成年男子膳食中15种稀土元素浓度和每日摄入量.方法通过双份饭法,采集分属4个膳食类型地区的天津、成都、镇江、太原共120例成年男子膳食样品,预处理后应用电感耦合等离子体质谱(ICP-MS)测定其中Ce、Dy、Er、Gd、Ho、La、Lu、Nd、Pr、Sc、Sm、Tb、Tm、Y、Yb的浓度,并计算每日各元素摄入量.结果获得了我国4地区成年男子膳食中15种稀土元素浓度和每日摄入量.结论我国4地区成年男子膳食中大部分稀土元素浓度符合正态分布,总稀土元素浓度范围约为24.68 ～ 109.27 μg/g,总稀土元素日摄入量约为24 μg/d,更新了我国成年男子膳食中稀土元素浓度和日摄入量参考值.

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.
