Lead and other heavy metals are found to leach from the glazes of some Tunisian glazed earthenware in concentrations high enough to constitute a serious health hazard. When yellow/green and white/green colored mugs available on the Tunisian market were filled with acetic acid solutions, concentrations of up to 51 microg lead per ml of leachate were measured. The values greatly exceed the limit allowed by the US Food and Drug Administration (FDA) regulations for a 24-h leaching test. The use of a traditional milk derivative (leben) widely consumed as a beverage in Tunisia as a leaching agent shows that amounts as high as 1407 microg of lead is ingested per mug of milk derivative consumed. The use of such utensils may constitute a serious health hazard to the Tunisian consumer. Stringent regulations and controls are therefore required to protect the consumer against lead and other heavy metals of non-occupational origin.
人们发现，突尼斯一些釉面陶的釉料中会渗出铅和其他重金属，其浓度高到足以构成严重的健康危害。当突尼斯市场上的黄绿相间和白绿相间的马克杯装满醋酸溶液时，测得每毫升沥出液中铅的浓度高达51微克。这些数值大大超过了美国食品药品监督管理局（FDA）法规对24小时沥出试验所允许的限值。在突尼斯被广泛当作饮料饮用的一种传统乳制衍生物（leben）用作沥出剂，结果表明，每饮用一杯这种乳制衍生物，会摄入高达1407微克的铅。使用这类器具可能会对突尼斯消费者构成严重的健康危害。因此，需要严格的法规和管控措施来保护消费者免受非职业来源的铅和其他重金属的危害。
