The results obtained between 1980 and 1985 in a Dutch monitoring programme investigating the presence of cadmium, lead, mercury and arsenic in meat, livers and kidneys of cattle are presented. During the period of investigation no clear trends were observed in the metal concentrations, except for lead in kidneys, for which the average concentration decreased from 0.48 mg/kg in 1980 to 0.24 mg/kg in 1985. The average cadmium and lead concentrations found in livers and kidneys in the present study were lower than those obtained for Dutch cattle investigated between 1970 and 1980. In general the metal concentrations found were in good agreement with data reported for other countries. The provisional Dutch legal limits for heavy metals in foods were exceeded only for cadmium in 2 kidney samples. Significant linear relations were found between the concentrations in livers and kidneys for arsenic, cadmium and lead. Significant relations were found also between the cadmium and lead concentrations in livers and between the cadmium levels in livers and kidneys and the age of the animals investigated.
本文展示了1980年至1985年期间在荷兰一项监测计划中获得的结果，该计划调查了牛的肉、肝脏和肾脏中镉、铅、汞和砷的存在情况。在调查期间，除了肾脏中的铅，金属浓度没有观察到明显趋势，肾脏中铅的平均浓度从1980年的0.48毫克/千克降至1985年的0.24毫克/千克。本研究中在肝脏和肾脏中发现的镉和铅的平均浓度低于1970年至1980年期间对荷兰牛进行调查所获得的浓度。总体而言，所发现的金属浓度与其他国家报告的数据高度一致。仅在2个肾脏样本中的镉超过了荷兰食品中重金属的临时法定限量。在肝脏和肾脏中，砷、镉和铅的浓度之间发现了显著的线性关系。在肝脏中的镉和铅浓度之间，以及在肝脏和肾脏中的镉水平与所调查动物的年龄之间也发现了显著关系。
