Under the influence of acidic agents, ceramic glazes and decorations for ceramics may release certain toxicants, especially lead and cadmium. Both elements are essential constituents of ceramic colours and glazes; their release to acidic foods is technologically unavoidable, but it may be minimized by the utilization of appropriate decoration agents and techniques. In most industrial countries, the release of toxicants from utensils is severely limited, the maximum permissible values and the methods of test and analysis being in part very different and not always in agreement with the demands and conditions of practice. The problems related to the release of toxicants from ceramic utensils are treated from the aspects of ceramics, test techniques, analytics, toxicology and food law, with special regard to the necessity for a well-balanced compromise between the justified hygienic demands of health protection and the actual technological possibilities. The endeavours of the ceramic industry of the GDF to produce ceramic utensils releasing as little toxicants as possible are outlined.
在酸性介质的影响下，陶瓷釉料及陶瓷装饰可能会释放某些有毒物质，尤其是铅和镉。这两种元素是陶瓷颜料和釉料的基本成分；它们向酸性食物中的释放从技术角度来说是不可避免的，但可以通过使用合适的装饰剂和技术将其降至最低。在大多数工业国家，餐具中有毒物质的释放受到严格限制，最大允许值以及测试和分析方法部分差异很大，且并不总是与实际需求和条件相符。从陶瓷、测试技术、分析、毒理学和食品法等方面探讨了与陶瓷餐具有毒物质释放相关的问题，特别关注在合理的健康保护卫生要求与实际技术可能性之间达成良好平衡的必要性。概述了德国陶瓷工业联合会努力生产有毒物质释放尽可能少的陶瓷餐具的情况。
