目前的研究确定了从马格达莱纳河流域收集的鱼类肌肉和肝脏组织中的总汞浓度。共有378个肌肉样本和102个肝脏样本被纳入分析。肌肉组织中汞的平均含量最高的是非肉食性动物皮洛odus blochii。然而，作为一个群体，食肉动物肌肉组织中的汞含量明显高于非食肉动物（p < 0.05）。4种鱼的体重与肌肉或肝脏中汞含量呈显著相关（p < 0.05）。在总汞浓度方面，没有观察到基于物种或性别的差异。
The present research determined the total mercury concentrations in muscle and liver tissue in fish collected from the Magdalena River watershed. A total of 378 muscle samples and 102 liver samples were included in the analysis. The highest mean mercury level in muscle tissue was found in the noncarnivore, Pimelodus blochii. However, as a group, carnivores had significantly higher (p < 0.05) mercury levels in their muscle tissue than noncarnivores. A significant correlation (p < 0.05) was obtained between fish mass and mercury concentrations in muscle or liver in four species. No differences were observed in total mercury concentration based either on species or gender.
