Resumo: | Toxicity tests have been widely used as a form of monitoring degraded areas. This work has as objective to evaluate the toxicity of copper for Piauçu from the determination of LC50 for 96 hours and analysis of alterations in the enzymatic and leukocyte patterns, in sublethal exposure (25 and 50% of the lethal concentration) for 96 hours. The LC50 of copper for Piauçu, during 96 hours, is 0.09±0.03 mg L-1 Cu2+. After exposure to the sublethal concentrations, enzymatic concentrations of Alanine Aminotrasferase and Aspartate Aminotransferase did not show any significant difference between the individuals of the control and metal groups. Plasma glucose showed a significant increase in fish exposed to 25 and 50% of LC50, when compared with control. Eosinophil, lymphocyte and neutrophil showed no significant difference from the control group. Thrombocytes increased significantly in the fish exposed to 50% of the LC50, as did monocytes in fish exposed to 25 and 50% of LC50. The results indicate that Piauçu is a species sensitive to the lethal effects of copper, and that exposure to the sublethal concentrations causes immune disorder; however, it does not induce liver damage according with the measured enzymes. |

Este trabalho teve como objetivo avaliar a toxicidade do cobre para o piauçu a partir da determinação da CL50 96h e da análise de alterações nos padrões enzimáticos e leucocitários, em exposição subletal (25 e 50% da concentração letal) por 96h. A CL50 96h do cobre para o piauçu foi 0,09 ± 0,03 mg L-1. Após a exposição às concentrações subletal, os valores das concentrações enzimáticas de Alanina Aminotrasferase e Aspartato Aminotransferase não apresentaram diferença significativa entre os indivíduos do grupo-controle e dos expostos ao metal. A glicose plasmática apresentou aumento significativo nos peixes expostos a 25 e 50% da CL50, quando comparados ao controle. O eosinófilo, o linfócito e o neutrófilo não apresentaram diferença significativa do grupo-controle. Os trombócitos aumentaram significativamente nos peixes expostos a 50% da CL50; os monócitos, nos peixes expostos a 25 e 50% da CL50. Os resultados indicam que o piauçu é uma espécie sensível aos efeitos letais do cobre e que a exposição a concentrações subletais causa um distúrbio imunológico, porém não induz dano hepático, de acordo com as enzimas mensuradas.Universidade Estadual De Maringá2009-12-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersiontestes ecotoxicológicosapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/493910.4025/actascibiolsci.v32i1.4939Acta Scientiarum.
