Copper concentrations were determined in muscle, liver, kidney, spleen and lung tissues of three dolphin species. Dolphins of Tursiops truncatus (young and adult), Stenella coeruleoalba and Grampus griseus were stranded along the Croatian coast. Concentrations in tissues of all three dolphin species were highest in the liver (4.92-16.5 μg/g) followed by kidney (2.85-5.29 μg/g). Similar levels were measured in muscle, spleen and lung in range 1.13-3.67 μg/g. Statistics analysis showed significant differences of Cu concentrations for muscle (p = 0.008), kidney (p = 0.04) and liver (p = 0.02) between the three dolphin species. Also, for all three species significant differences between tissue types of the same species were determined (p < 0.001, all). However, there were no significant differences in Cu levels of the same tissues between males and females within same species. Also, significant differences of body length and weight between three dolphin were found (p < 0.001, both).
测定了三种海豚的肌肉、肝脏、肾脏、脾脏和肺组织中的铜浓度。宽吻海豚（幼体和成体）、条纹原海豚和灰海豚在克罗地亚海岸搁浅。所有三种海豚组织中的浓度在肝脏中最高（4.92 - 16.5微克/克），其次是肾脏（2.85 - 5.29微克/克）。肌肉、脾脏和肺中的浓度相似，范围在1.13 - 3.67微克/克。统计分析表明，三种海豚之间肌肉（p = 0.008）、肾脏（p = 0.04）和肝脏（p = 0.02）中的铜浓度存在显著差异。此外，对于所有三种物种，同一物种不同组织类型之间也存在显著差异（p < 0.001，全部）。然而，同一物种内雄性和雌性相同组织中的铜水平没有显著差异。此外，还发现三种海豚之间的体长和体重存在显著差异（p < 0.001，两者皆是）。
