Trace element concentrations were determined in meat, kidney and liver tissue of cattle, which had resided more than 18 months in areas historically contaminated by emissions from the non-ferrous metal industry or in regions with normal background metal contamination levels in Belgium. Trace element levels were determined by inductively coupled plasma-mass spectrometry. Lead, arsenic and cadmium concentrations in meat were low for all cattle. Concentrations in kidneys were, respectively, 1.8-, 2.2- and 2.5-fold higher in cattle from the contaminated areas compared to animals from reference areas. The European maximum level for cadmium in kidney was exceeded by 75% of the kidneys from contaminated areas and 47% of the kidneys from reference areas. Lead, arsenic and cadmium concentrations in bovine livers from contaminated areas were increased by a factor of 2.3. Zinc levels in livers and kidneys were within normal ranges, but 20% higher in the contaminated areas compared to reference areas. Copper levels in livers were high in all areas. Dairy cattle accumulated significantly higher levels of cadmium in kidneys and of lead in liver and kidneys than did beef cattle.
对在比利时历史上受到有色金属行业排放污染的地区或背景金属污染水平正常的地区生活超过 18 个月的牛的肉、肾和肝组织中的微量元素浓度进行了测定。采用电感耦合等离子体质谱法测定微量元素水平。所有牛的肉中铅、砷和镉浓度均较低。与参照区动物相比，污染区牛的肾中铅、砷和镉浓度分别高出 1.8 倍、2.2 倍和 2.5 倍。污染区 75%的肾脏和 47%的参照区肾脏超过了欧洲肾脏中镉的最大限量。污染区牛的肝中铅、砷和镉浓度增加了 2.3 倍。肝和肾中的锌水平在正常范围内，但污染区比参照区高 20%。所有地区的肝铜水平都很高。奶牛在肾脏中积累的镉和在肝脏和肾脏中积累的铅明显高于肉牛。
