Summary: | •Copper toxicity to a tropical fish varied greatly in different Amazonian waters.•The biotic ligand model could not capture this variability.•Possible physiological protection was offered by natural organic matter.•Care must be used in applying BLM to fish in tropical waters.
Copper at high concentrations is an ionoregulatory toxicant in fish and its toxicity is known to be strongly modulated by the water chemistry. The toxicity of Cu to the tropical fish cardinal tetra (Paracheirodon axelrodi) was investigated in waters from two major rivers of the Amazon watershed: the Rio Negro (filtered |
