Resumen
[ES]Debido a los problemas asociados a la producción del aceite se propuso este trabajo para conocer el poder de toxicidad sobre bioindicadores presentes en las zonas acuáticas cercanas a las salidas de residuos de las almazaras. En nuestro estudio utilizamos la especie Daphnia magna de la clase Crustácea. Para comprobar la toxicidad del alpechín se realizaron dos experimentos: un primero de supervivencia donde se obtuvo una dosis letal del 50% con una dilución de alpechín de 4,74% demostrando una alta toxicidad sobe estos individuos. El segundo ensayo se centró en los efectos subletales como es la reproducción, con un experimento de exposición de 21 días a dos diluciones de 1% y 2%.
[EN]Due to problems, associated with oil production, this work was proposed to find out the power of toxicity on bio-indicators present in the aquatic areas near the waste outlets of the oil mills. In our study, we used the Daphnia magna species, which belong to the Crustacea class. To verify the toxicity of vegetable water, two experiments were carried out: the first one was a survival experiment where a lethal dose of 50% was obtained with a concentration a vegetable water dilution of 4.74%, thus demonstrating a high toxicity on these individuals. The second trial focused on sub-lethal effects, such as reproduction, with a 21-day exposure to two dilutions of 1% and 2%,
