摘　　要：目的了解2017年清远市市售水产品中稀土元素的含量,并对其进行健康风险评价。方法采用高压密罐消解-电感耦合等离子体质谱仪(以下简称ICP-MS)检测16种稀土元素,并参照美国环保局(USEPA)推荐的健康风险方法,对稀土元素可能对人体健康产生的健康风险进行评价。结果 2017年清远市市售水产品中稀土元素的含量为4.9～1 749 g/kg,平均为187 g/kg。贝类水产品的稀土元素平均含量最高,其次是蟹和虾,最低是鱼。居民通过水产品摄入的稀土元素日均摄入量为0.11 g/kg·d,远远低于安全剂量标准。结论 2017年清远市市售水产品中稀土元素污染程度较低,居民通过市售水产品摄入稀土元素是安全的。[Objective]To understand the content of rare earth elements in aquatic products from market in Qingyuan City in2017,and evaluate their health risk. [Methods] 16 kinds of rare earth elements were detected by inductively coupled plasmamass spectrometry（ ICP-MS） after high pressure tank digestion. The health risks of rare earth elements were evaluated with reference to the health risk method recommended by US Environmental Protection Agency（USEPA）.[Results] The content of rare earth elements of aquatic products in Qingyuan City was 4.9-1 749 g/kg,and the average content was 187 g/kg. The average content of rare earth elements in shellfish aquatic products was the highest,followed by crabs and shrimp,and that in fish was the lowest. The daily intake of rare earth elements ingested by residents through aquatic products was 0.11 g/kg·d,which was far below the safe dose.[Conclusion] The pollution level of rare earth elements in aquatic products in Qingyuan City is low,and it is safe for residents to ingest rare earth elements through aquatic products.
