| 中文摘要: |
| 目的 研究陶瓷制品口缘和器身中多种金属元素的迁移风险，并考察合规判定规则。方法 采用体积分数为4%乙酸模拟物对41种杯类陶瓷口缘和器身进行3次迁移实验，用电感耦合等离子体质谱法对试液中的18种金属元素进行检测。结果 陶瓷制品口缘和器身的金属元素迁移量平均值随迁移次数递减;铝(Al)、钴(Co)、锌(Zn)、铅(Pb)的最大迁移量超过讨论限量10%的样品数，明显高于其他金属元素的样品数，且同样特征的样品中口缘的样品数高于器身的样品数。结论 陶瓷制品具有较高的Al、Co、Zn、Pb迁移风险，而且口缘比器身的迁移风险更高。建议金属元素迁移量以第1次迁移实验结果进行合规判定。 |

| The work aims to study the migration risk of various metal elements in the drinking rim and body of ceramic products and investigate the rule of compliance determination. 3 migration tests were performed on the drinking rim and body of 41 different types of ceramic mugs with 4% (volume fraction) acetic acid simulant, and 18 elements were detected by inductively coupled plasma mass spectrometry. The mean migration of metal elements in the drinking rim and body decreased as the times of migration increased. The number of samples with the greatest migration of Aluminum (Al), Cobalt (Co), Zinc (Zn) and Lead (Pb) exceeding 10% of the migration discussion limit was significantly higher than that of other metal elements, and the number of samples with the same characteristic in the drinking rim was higher than that in the body. Ceramic products have a high migration risk of Al, Co, Zn and Pb, and the migration risk in the drinking rim is higher than that in the body. It is recommended to determine the compliance of the migration amount of various metal elements with the first migration test results. |
