研究了阿根廷巴伊亚布兰卡河口三种鲨鱼肌肉和肝脏中总汞、镉和锌的积累。 汞浓度在所分析物种的肌肉（范围：0.77-2.99 μ g/g）和肝脏（0.79-2.26 μ g/g）中相似。 镉和锌在肝脏中的浓度高于肌肉。 金属浓度的频率分布被认为是对数正态分布。 金属浓度与鲨鱼的总长度成比例增加。 在金属浓度的显着差异归因于在河口的位置没有发现。鲨鱼的物种之间的饮食差异似乎是最重要的原因，在其金属浓度的差异。
Total mercury, cadmium, and zinc accumulation was studied in muscle and liver of three species of shark from the Bahia Blanca estuary, Argentina. The mercury concentrations were similar in both muscle (range: 0.77-2.99-mu-g/g) and liver (0.79-2.26-mu-g/g) of the analyzed species. Concentrations of cadmium and zinc were higher in liver than in muscle. The frequency distributions of metal concentrations were found to be log-normal. The metal concentrations increased proportionally to the total length of the sharks. Significant differences-attributable to location in the estuary-in metal concentrations were not found. Dietary differences among species of shark seemed to be the most important causes for differences in their metal concentrations.
