Total mercury concentrations were determined in muscle, liver and kidney of Cichlia ocellaris and Colossoma macropomum sampled at Tapajos and Carnapijo Rivers in Amazon ecosystem during the flood period of 2009. In background area the highest levels of mercury were observed in liver of piscivorous (0.3 ± 0.03 ug/g dry wt) and non piscivorous fish (0.20 ± 0.1 ug/g dry wt), but in contaminated area the highest level of mercury in piscivorous fish was detected in liver (0.45 ± 0.27 ug/g dry wt) and in muscle (0.26 ± 0.05 ug/g dry wt) of non piscivorous fish. These results suggested that the presence of anthropogenic source plays a key role in the pattern of mercury distribution in fish tissues.
在亚马逊生态系统的托坎廷斯河和卡纳皮焦河流域的洪水期，对在 2009 年采集的眼斑拟石首鱼和巨臀脂鲤的肌肉、肝脏和肾脏中的总汞浓度进行了测定。在背景地区，观察到肉食性鱼类（0.3±0.03μg/g 干重）和非肉食性鱼类（0.20±0.1μg/g 干重）肝脏中的汞含量最高，但在污染地区，非肉食性鱼类的肝脏（0.45±0.27μg/g 干重）和肌肉（0.26±0.05μg/g 干重）中的汞含量最高。这些结果表明，人为污染源的存在在鱼类组织中汞的分布模式中起着关键作用。
