Abstract EN
In order to determine copper toxicity (LC50) to a local species (Cnesterodon decemmaculatus) in the South American Pilcomayo River water and evaluate a cross-fish-species extrapolation of Biotic Ligand Model, a 96 h acute copper toxicity test was performed.
The dissolved copper concentrations tested were 0.05, 0.19, 0.39, 0.61, 0.73, 1.01, and 1.42 mg Cu L-1.
The 96 h Cu LC50 calculated was 0.655 mg L-1 (0.823-0.488).
96-h Cu LC50 predicted by BLM for Pimephales promelas was 0.722 mg L-1.
Analysis of the inter-seasonal variation of the main water quality parameters indicates that a higher protective effect of calcium, magnesium, sodium, sulphate, and chloride is expected during the dry season.
The very high load of total suspended solids in this river might be a key factor in determining copper distribution between solid and solution phases.
A cross-fish-species extrapolation of copper BLM is valid within the water quality parameters and experimental conditions of this toxicity test.
