摘　　要：目的 获得中国不同地区食物中稀土元素的含量,评估中国人膳食中稀土元素的摄入量。方法 结合中国总膳食研究的方法,应用电感耦合等离子体质谱法,获得主要膳食中稀土元素的含量水平,并结合食物消费量数据得到我国居民膳食中稀土元素的摄入量。结果 我国成年男子的16种稀土元素的摄入量平均为250.9μg/天,总体范围从27.5-706.2μg/天。结论 结合我国目前的食品安全现状,关注中国居民的膳食稀土元素的摄入量同样重要。Objective To obtain REEs content in different food and assess the dietary intakes of REEs in different provinces in China. Methods Using the total diet study method, the analytical samples were obtained in different provinces by food consumption survey. The REEs levels of dietary samples were determined by inductively coupled plasma mass spectrometry （ICP-MS）. Results Dietary intake of 16 REEs was averagely was 250.9μg/d for adults, ranging from 27.5μg/d to 706.2μg/d. Conclusion The results remind us that it is the time to pay more attention on dietary intake of REEs in China.
