Measured copper toxicity to Cnesterodon decemmaculatus [Pisces : Poeciliidae] and predicted by biotic ligand model in pilcomayo river water a step for a cross - fish - species extrapolation

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 96h acute copper toxicity test was performed. The dissolved copper concentrations tested...

520 |a 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 96h 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 1.42mg Cu L -1. The 96h Cu LC50 calculated was 0.655mg L -1 [0.823-0.488]. 96-h Cu LC50 predicted by BLM for Pimephales promelas was 0.722mg 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.
