1992 - 1994年期间，在沿着意大利和希腊西海岸发现的条纹海豚（Stenella coeruleoalba）、短吻海豚（Tursiops truncatus）和普通海豚（Delphinus德尔菲）胎儿的肝脏和肾脏中测定了三丁基锡及其降解产物单丁基锡（MBT）和二丁基锡（DBT）的浓度。丁基锡（BT）化合物中检测到几乎所有的样品分析，并高于在肝脏中的肾脏。肾中的总BT浓度为0.78 - 8.05 m gg/kg湿重，肝中为0.015 - 1.02 m gg/kg湿重。蓝耳白宽吻海豚有较低的BT浓度比条纹海豚。虽然只分析了一个胎儿样本，但它显示了所有样本中最高的BT浓度。与其他成年海豚中的BT浓度不同，怀孕海豚的肝脏中的BT浓度较高（4.35微克/千克湿重），这表明BT从母亲转移到胎儿。BT浓度在性别之间没有显著差异。在分解产物中，DBT在大多数肝脏样品中占主导地位，MBT在肾脏中更丰富。虽然已知在发达国家沃茨的鲸目动物中发现了BT浓度，但我们的观察强烈表明，在S. coeruleoalba的相似或高于报告的其他Stenella物种收集沿海地区靠近港口或码头。版权所有# 2000约翰威利父子有限公司。
Concentrations of tributyltin (TBT) and its degradation products, monobutyltin (MBT) and dibutyltin (DBT), were determined in the liver and kidney of striped dolphins ( Stenella coeruleoalba), bottlenose dolphins ( Tursiops truncatus) and in a fetus of the common dolphin (Delphinus delphi) found stranded along the western Italian and Greek coasts in the period 1992‐1994. Butyltin (BT) compounds were detected in almost all the samples analyzed and were higher in the kidney than in the liver. Total BT concentrations were 0.78‐8.05m gg ˇ 1 wet wt in kidney and 0.015‐1.02m gg ˇ 1 wet wt in liver of S. coeruloealba. Bottlenose dolphins had lower BT concentrations than striped dolphins. Although only one fetal sample was analyzed, it showed the highest BT concentrations of all. Unlike BT concentrations in the other adult dolphins, in the pregnant dolphin they were higher in the liver (4.35 m gg ˇ 1 wet wt), suggesting that BTs are transferred from mother to fetus. No significant differences in BT concentrations were found between sexes. Of the breakdown products, DBT was predominant in most liver samples and MBT was more abundant in kidney. Although BT concentrations are known to be found in cetaceans inhabiting waters of developed countries, our observations strongly suggest that concentrations found in S. coeruleoalba were either similar to or higher than those reported for other Stenella species collected from coastal areas close to harbors or marinas.
