江西省市售不锈钢餐具中24种元素迁移量调查

目的 了解江西省市售不锈钢餐具中24种元素迁移含量，为江西省食品安全风险监测工作提供数据支持。方法 从江西省11个地市的超市、农贸市场、网店采集65份不锈钢餐具，采用电感耦合等离子体质谱法分析测定。结果 65份餐具均有多种元素迁移检出，样品总检出率为100.0%，24种元素迁移总量范围为3.35×10 - 2～1.76 mg/kg。铅、铬、镍元素的迁移检出率分别为23.1%、100.0%、87.7%，最大检出值分别为3.39×10 - 4、0.137、1.35×10 - 2 mg/kg，均未超过限量标准。结论 江西省市售不锈钢餐具中元素迁移普遍存在，建议制定相关标准，加强监管力度。

Investigation on the migration of 24 elements in stainless-steel dinnerware sold in Jiangxi Province

Objective To investigate the migration of 24 elements in stainless-steel dinnerware sold in Jiangxi Province, and to provide reference for food safety risk monitoring. Methods A total of 65 stainless-steel dinnerware samples were purchased from supermarkets, farmers markets and online stores in 11 cities in Jiangxi Province. The migration of 24 elements were determined by inductively coupled plasma mass spectrometry. Results All 65 samples were detected with migration of multiple elements. The total detection rate was 100.0% with total concentrations ranging from 3.35 ×10-2 mg/kg to 1.76 mg/kg. The detection rates of lead, chromium and nickel were 23.1%, 100.0% and 87.7%, respectively, with the highest contents of 3.39×10-4 mg/kg, 0.137 mg/kg, 1.35×10-2 mg/kg, respectively, but none of them exceeded the standard limits. Conclusion The element migration is common in stainless-steel dinnerware sold in Jiangxi Province. It is recommended that relevant regulation be established with enhanced supervision.
