目的：研究粮食中稀土元素残留的检测方法，了解本地区粮食中稀土残留情况。方法2014年河北10个重要地区开展的食品安全监测项目中，采用ICP-MS法对Sc、Y、La、Ce、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb、Lu 16种稀土元素进行检测。结果在所检测的296份样品中，全部样品均检测出Y元素，其余元素均在样品中部分检出，检出样品均未超出国家规定的稀土元素的最大残留限量(MRLs)。结论 ICP-MS法可以有效地检出Sc、Y、La、Ce、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb、Lu共16种稀土元素，通过检测结果可看到有必要持续监测和控制粮食中稀土元素的残留情况，从而保障人们的安全健康。

Objective To research the detection methods of rare earth elements residues in food, in order to realize the rare earth residue in this area.MethodsAccording to the detection methods in 2014 food safety monitoring program, which were carried out in 10 main areas in Hebei province of China, 16 rare earth element in grain, including Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, were determined by inductively coupled plasma mass spectrometry (ICP-MS).ResultsIn all 296 samples, Y was found in all samples. Other rare earth elements were found in several samples. All samples detected did not contain the rare earth elements beyond the Maximum Residue Limit (MRLs) of the national requirement.ConclusionThe ICP-MS is an efficient method to detect the 16 rare earth element in grain. It is necessary to assure safety and health of human beings by monitoring the rare earth element residue in grain uninterruptedly.
