Abstract

Abstract Zinc, cadmium, and lead in livers, kidneys, and feathers of 48 young and adult Atlantic puffins found dead or dying off the coast of Galicia (Northwest Spain) were determined. The most abundant between the three elements was the essential metal zinc, with highest mean levels (173 ± 9 mg/kg dry weight) in livers. For the two non-essential metals, the highest mean levels of cadmium were found in kidneys (22.1 ± 1.0 mg/kg dry weight), and of lead in feathers (1.31 ± 0.10 mg/kg dry weight). For some birds, concentrations of zinc and cadmium exceeded established risk levels. The concentrations of the three metals were positively correlated in livers. In kidneys and livers, cadmium levels were correlated. With respect to age, the levels of the three metals in adults were higher than in young animals. Female birds showed significantly higher levels than males. The results are useful for establishing baseline data of the concentrations of the three metals for this species. Graphical Abstract

西班牙大西洋海雀肝脏、肾脏和羽毛中锌、镉和铅的含量

在西班牙西北部加利西亚海岸发现的48只大西洋海鹦的肝脏、肾脏和羽毛中检测了锌、镉和铅的含量。三种元素中含量最高的是必需金属锌，肝脏中锌的平均含量最高(173±9 mg/kg干重)。对于这两种非必需金属，肾脏中镉的平均含量最高(22.1±1.0 mg/kg干重)，羽毛中的铅含量最高(1.31±0.10 mg/kg干重)。对一些鸟类来说，锌和镉的浓度超过了既定的危险水平。三种金属在肝脏中的浓度呈正相关。在肾脏和肝脏中，镉水平是相关的。就年龄而言，成年动物体内这三种金属的含量高于幼年动物。雌鸟的水平明显高于雄鸟。研究结果对建立该物种三种金属浓度的基线数据是有用的。图形抽象
