| 目的 使用高效检测技术快速筛查市售不锈钢电热水壶的重金属元素含量及其迁移量情况，有效保障消费者健康安全。方法 本研究利用电感耦合等离子体质谱仪（ICP-MS）测量了20批次不锈钢电热水壶样品中13种重金属元素迁移量，并检查各产品的标签标识。使用手持式X-射线荧光光谱仪（XRF）快速检测了不锈钢电热水壶各个部件的元素含量并对其材质进行分析。结果 多元素迁移量实验表明，部分样品存在重金属迁出现象，尤其是锰（Mn）、铝（Al）元素。XRF实验表明，部分样品使用非食品级不锈钢作为原材料。此外，一些样品还存在产品标签标识不合格、标注材质与实际用料不一致等问题。结论 ICP-MS和XRF实验结果揭示了不锈钢材质是导致重金属迁出的关键因素，本研究为提升行业质量监管效能、保障消费者健康安全及推动产业技术升级提供理论依据。 |

| Objective To rapidly screen the elemental content and migration of heavy metals in commercially available stainless steel electric kettles using efficient detection technologies, thereby safeguarding consumer health and safety. Methods In this study, 20 batches of stainless steel electric kettle samples were analyzed using inductively coupled plasma mass spectrometry (ICP-MS) to determine the migration levels of 13 heavy metal elements, along with label compliance checks. A handheld X-ray fluorescence (XRF) spectrometer was employed to rapidly detect the elemental content of key components and analyze their material composition. Results Multi-element migration experiments revealed heavy metal migration in some samples, particularly manganese (Mn) and aluminum (Al). XRF analysis identified the use of non-food-grade stainless steel in certain products. Additionally, non-compliant product labeling and discrepancies between labeled and actual material compositions were observed in some samples. Conclusion The combined ICP-MS and XRF results demonstrated that stainless steel material quality was a critical factor influencing heavy metal migration. This study provides theory basis for enhancing industry quality regulation, ensuring consumer health and safety, and promoting technological advancements in product manufacturing. |
