Cadmium and lead contents were determined in pork and duck liver pastes produced in Spain. The average concentration levels that were measured were 19 ng/g for cadmium and 578 ng/g for lead in pork liver pastes and 14 ng/g for cadmium and 157 ng/g for lead in duck liver pastes. The possible sources of these trace elements were investigated: product formulation, technological process and packaging. It has been observed that the contents of lead in pork liver pastes are higher than would be expected from the liver content alone, and that the main source of lead is the tin container.
测定了西班牙生产的猪肝酱和鸭肝酱中的镉和铅含量。测得的平均浓度水平为：猪肝酱中镉含量为19纳克/克，铅含量为578纳克/克；鸭肝酱中镉含量为14纳克/克，铅含量为157纳克/克。对这些微量元素的可能来源进行了调查：产品配方、工艺流程和包装。据观察，猪肝酱中的铅含量高于仅由肝脏本身所含铅量所预期的水平，且铅的主要来源是锡制容器。
