摘　　要：目的:调查珠海市市售水产品中稀土元素的含量水平。方法:随机采集珠海市5个功能区的农贸市场、商超等共150份水产动物样品,采用微波消解-电感耦合等离子体质谱法测定样品16种稀土元素含量。结果:2022年珠海市售水产品中稀土元素总量为0.01~6679.64μg·kg^(-1),平均含量为176.2μg·kg^(-1),中位值为6.0μg·kg^(-1)。不同类别的水产品种稀土元素含量变化大致为双壳类>腹足、头足类>甲壳类>鱼类。以轻稀土元素富集为主,以轻稀土元素铈(Ce)平均含量最高、其次为镧(La)、钕(Nd),重稀土元素钇(Y)较高。结论:珠海市部分地区及种类水产品中稀土元素相对含量较高,建议加强监管力度。Objective:To investigate the content level of rare earth elements in aquatic products in Zhuhai.Method:150 samples of aquatic products in five functional areas were randomly collected from farmers’markets and supermarkets,and the content of 16 rare earth elements was determined by microwave digestion-inductance coupled plasma mass spectrometry.Result:The total amount of REEs in aquatic products in Zhuhai in 2022 was 0.01~6679.64μg·kg^(-1),the average content was 176.2μg·kg^(-1),and the median value was 6.0μg·kg^(-1).The content of rare earth elements in different categories of aquatic products is roughly bivalves>gastropod,cephalopod>crustaceans>fish.The distribution characteristics of rare earth are mainly enriched by light rare earth elements,and the average content of Ce is the highest,followed by La and Nd,and Y of the heavy rare earth element is higher.Conclusion:The content of rare earth elements in some areas and species of Zhuhai is relatively higher,so it is suggested to strengthen supervision.
