The distribution of metals (Cd, Cu, Zn, Fe, Cr, Pb and Sn) were investigated in various tissues and organs obtained from striped dolphins (Stenella coeruleoalba) stranded along the Apulian coasts (Southern Italy) during April-July 1991. Metals were determined by atomic absorption spectrophotometry. Metal concentrations were generally high in the liver, and low in brain and melon. Some metals showed organ-specific accumulations: copper, tin and zinc exhibited high concentrations in liver, the highest cadmium concentration was observed in kidney. Pathological, microbiological and parasitological surveys were performed on the animals. It was not possible to relate dolphin death to a specific cause, or to contaminants; however, the accumulation of metals may contribute to certain pathological alterations.
1991年4月至7月期间，对在意大利南部普利亚海岸搁浅的条纹海豚（Stenella coeruleoalba）的各种组织和器官中金属（镉、铜、锌、铁、铬、铅和锡）的分布情况进行了调查。通过原子吸收分光光度法测定金属含量。肝脏中的金属浓度普遍较高，而大脑和瓜状体中的浓度较低。一些金属表现出器官特异性积累：铜、锡和锌在肝脏中浓度较高，肾脏中镉的浓度最高。对这些动物进行了病理、微生物和寄生虫学调查。无法将海豚的死亡与特定原因或污染物联系起来；然而，金属的积累可能会导致某些病理变化。
