El objetivo del presente trabajo fue evaluar la toxicidad letal media por exposicion a cianuro libre en efluentes y relaves mineros. El estudio se realizo durante el periodo poca lluvia, donde fueron seleccionadas cuatro muestras representativas de efluentes, asi como relaves mineros, estableciendose tres replicas por cada muestra ambiental para el analisis. Para la determinacion de la toxicidad letal media, fueron ensayos cuatro tratamientos de dilucion mas un tratamiento control, asi como determinadas bajo condiciones experimentales segun recomendaciones de la Comunidad Economica para la Cooperacion y el Desarrollo, la utilizacion de Brachydanio rerio y Eisenia andrei como biomodelos. Se observo, una mortalidad del 100% de los individuos de Brachydanio rerio a las 24 horas de duracion del ensayo, cuya concentracion letal media correspondio a 0.078mg/L-1, mientras que en Eisenia andrei la concentracion letal media ocurrio a las 48 horas de duracion del ensayo y correspondio a 0.016g de relave. Se concluyo que los bioensayos indicaron efectos de toxicidad inmediata en efluentes y relaves mineros expuestos a cianuro libre. Palabras clave: toxicidad letal media, exposicion, cianuro libre, efluentes y relaves mineros, Brachydario rerio, Eisenia andrei, Puno-Peru. Evaluation of lethal half toxicity for exposition to free cyanide in outflows and wash again miners utilizing the biomodels Brachydanio and Eisenia andrei Abstract The objective of present work was to evaluate the lethal half toxicity for exposition to free cyanide in outflows and wash again miners. The study sold off during the period of a little rain, where were selected four representative signs of outflows, those wash again miners, established three replies for each environmental sign for analysis. For the determination of lethal half toxicity, four further treatments of dilution were essays a treatment control, thus the determined under experimental conditions according to recommendations of the Economic Community for Cooperation and Development, Brachydanio rerio utilization re-river and Eisenia andrei like biomodels . It was observed, a mortality of Brachydanio rerio 100 % of the individuals’ re-river to the 24 hours of duration of the essay, whose lethal half concentration 1 corresponded to 0.078mg/L, while than in Eisenia andrei the lethal half concentration occurred to the 48 hours of duration of the essay and corresponded to 0.016g of wash again. It was been understood that bioessays indicated effects of immediate toxicity in outflows and wash again miners exposed to free cyanide. Keywords: lethal half toxicity, exposition, free cyanide, outflows and wash again miners, Brachydanio rerio, Eisenia andrei, Puno-Peru.
