Abstract

The U.S. Food and Drug Administration (FDA) conducted a survey of domestic and imported ceramic dinnerware from January to February 1992 to determine the status of lead leaching from this ware. Ceramicware was screened at the collection point by using the Quick Color Test (QCT); if the QCT was positive, the ware was analyzed in the laboratory by using atomic absorption spectroscopy (AAS). For imports, 5222 lots were examined using the QCT. Of these lots, 46 exceeded FDA's 1991 guidelines as determined by using AAS. For domestic ware, 676 lots were examined using the QCT, and 17 lots exceeded the 1991 guidelines. The violation rates, 0.9% for imports and 2.5% for domestic ware, were about twice as high as they would have been under the 1980 guidelines.

摘要

1992年1月至2月期间，美国食品药品监督管理局（FDA）对国产和进口陶瓷餐具进行了一项调查，以确定此类餐具铅溶出的情况。在收集点使用快速颜色测试（QCT）对陶瓷餐具进行筛选；如果QCT呈阳性，则在实验室使用原子吸收光谱法（AAS）对该餐具进行分析。对于进口产品，使用QCT检查了5222批产品。在这些批次中，有46批超过了FDA 1991年的指导标准（通过AAS测定）。对于国产餐具，使用QCT检查了676批产品，有17批超过了1991年的指导标准。违规率方面，进口产品为0.9%，国产餐具为2.5%，大约是1980年指导标准下违规率的两倍。
