Toxicity of nanomaterials to Amazonian fish in different water types

The Negro and Solimoes rivers in the Amazon Basin house an incredible diversity of fish, up to 3000 species, and are critical to the economies and cultures of the communities through which they run. The waters of the Rio Negro are clear and black, with a high concentration of dissolved organic material but almost no dissolved salts. The waters of the Solimoes are quite turbid, with a high sediment load and dissolved salt levels more typical of a freshwater river. The unintentional release of toxins from large-scale mining and petroleum extraction industries is a major threat to the health of the Amazonian ecosystem but little is known about the bioactivity of toxins in the unique water types of the Negro and Solimoes rivers.
