Fil: Fabrizio de Iorio, Alicia Rosa. Universidad de Buenos Aires. Facultad de Agronomía. Buenos Aires, Argentina. 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. application/pdf doi:10.1155/2012/849315 issn:1687-8191 http://ri.agro.uba.ar/greenstone3/library/collection/arti/document/2012Casares eng info:eu-repo/semantics/openAccess openAccess http://ri.agro.uba.ar/greenstone3/library/page/biblioteca#section4 Journal of Toxicology Vol.2012 http://www.hindawi.com/ CALCIUM CHLORIDE COPPER MAGNESIUM RIVER WATER SODIUM SULFATE ANALYSIS OF VARIANCE BIOTIC LIGAND MODEL CONTROLLED STUDY FISH LC 50 NONHUMAN PIMEPHALES PROMELAS RIVER SUSPENDED PARTICULATE MATTER TOXICITY TESTING WATER QUALITY CNESTERODON DECEMMACULATUS PIMEPHALES PROMELAS PISCES POECILIIDAE Measured copper toxicity to Cnesterodon decemmaculatus (Pisces : Poeciliidae) and predicted by biotic ligand model in pilcomayo river wate : a step for a cross-fish-species extrapolation article info:eu-repo/semantics/article info:ar-repo/semantics/artículo publishedVersion info:eu-repo/semantics/publishedVersion |
