This paper reports on total Hg concentrations in muscle tissue from 12 fish species collected in the Itacaiúnas and Parauapebas Rivers in the Carajás region, South Pará. It is found that carnivorous species present Hg concentrations higher than herbivorous and omnivorous species. Also, large carnivorous species presented higher Hg concentrations than smaller carnivorous species. Significant positive relationships are found between fish weight and total Hg concentrations for at least two species studied in detailed, the carnivorous Paulicea lutkeni (jaú) and Serrasalmus nattererii (piranha).
本文报道了在巴西北部帕拉州卡拉雅斯地区的伊塔卡尤纳斯河和帕劳阿佩巴斯河采集的12种鱼类肌肉组织中的总汞浓度。研究发现，肉食性鱼类的汞浓度高于草食性和杂食性鱼类。此外，大型肉食性鱼类的汞浓度高于小型肉食性鱼类。对于至少两种详细研究的鱼类，肉食性的卢氏保罗丽鱼（jaú）和纳氏锯脂鲤（食人鱼），发现鱼的体重与总汞浓度之间存在显著的正相关关系。
