- Abstract
We collected 06 samples of sediment and 264 samples of fish. The Hg in sediments ranged between 0.038 and 0.065 μg.g-1.The results indicate that sediment is in agreement with "uncontaminated" Amazonian rivers. The carnivorous species presented the highest level of Hg on muscle (mean 0.927 μg/g-1), followed by piscivorous (mean 0.873 μg.g-1), planktophagus (mean 0.566 μg.g-1), omnivorous (mean 0.533 μg.g-1) and detritivorous (mean 0.176 μg/g-1). Fourty four percent (44%) of the total species collected presented mean levels of THg on muscle, a percentage greater than the threshold recommended by WHO.
